This page illustrates the main weapon systems embarked on the ships of E.F.N.I., and the other EA systems that, even if are not in use in the E.F.N.I., are intresting from the technical point of view. The basic principles of some weapon families are illustrated by technical schemes.

The nominal Bore of a weapon is the diameter of the beam/projectile/bolt ( or the dimensions of the impact area, if this is not circular ).
The Power/energy is given in Joules (Energy) for the weapons that operates with pulses/bolts, and it is the energy of a single shot, while it is expressed in Watts (Power) for the weapons operating in continuous fire mode (continuous beam).


The most powerful weapons utilized by the Earthforce are the Earthforce Arsenals AEGIS Heavy Particle G.O.D. cannons.
G.O.D. is the acronymous for Global Orbital Defence, because the first incarnations of this weapon, the Mk II and Mk III were conceived for the Global Orbital Defence Satellites, a powerful network of heavy satellites, placed around the Earth, and conceived early after the end of the Earth-Minbari War; the Mk I was an experimental model for the cannons of the satellites, while the MkIV, developed for the "battlemaster project", was the workbench for the shipborne family, that saw the service with the Warlock Heavy Destroyers.
The origin of the concept is very obvious: a weapon system able to avoid another battle of the Line. Beyond the batteries of missiles and the defensive weapons, the main offensive arm of the large G.O.D. satellites was a weapon "able to destroy a Sharlin Cruiser with a single shot, at ranges exceeding the standard range of the Minbari main beam weapons". Even if the range requirement was just accomplished, the Earthforce Arsenals, the "weapon arm" of the EFRAD, went well beyond the requirements regards to the power of the weapon, as can be seen in the attached technical Data. The G.O.D. cannon is a complex weapon, a large linear particle accelerator fed by a battery of Synchrothrons (accumulation rings)
See technical schematics .
The heavy particles (cesium nuclei) are accumulated and accelerated in the primary accumulation rings, until the buildup of a discharge is completed. Then the particles of all the accumulation rings are released in a collector an driven in the barrell of the weapon, that is a linear accelerator able to increase the speed/energy of the particles to relativistic levels and drive them against the target: the concept is very classic, but the technologies employed are very advanced, mainly in the magnetic fields generators and in the control of the particle stream.

The early models of G.O.D. cannons had three large accumulation rings, but the progress in the synchronization of the primary feeders, the devices that drive the particle streams from the accumulation rings to the collector, enabled to build weapons with an elongated design like the Mk V, that allowed this weapon to be installed in the hull of a ship, the Warlock class destroyers, giving to the Earth ships a firepower never experienced before, and up to the long ranges. The drawbacks of the G.O.D. cannons are the low rate of fire and the dimensions, that imposes a spinal installation.

The accumulative working principle, yet applied in the Omega heavy particle/pulse cannons, allows a peak power that can be enormously higher than the average power used to feed the weapon, and is this capability to operate a "buildup" of the discharge, in addiction to the long barrell of the second stage accelerator, is the technology that gives to the G.O.D. cannons their impressive destructive power: to give an idea, can be taken as reference the most infamous beam weapon in standard use in an ISA Navy, the "Nur'nil'bok" ("lone sword"), the main bow beam of the Minbari Sharlin Warcruisers. This exceptional (and deadly) weapon has a core diameter of 10 meters, and a power output of more than 7300 Terawatts in continuous mode, and this means that even the power input must be the same.
The Aegis Mk V of the Warlocks has a maximum power input of 2400 Terawatts, about twice a Raytheon OMEGA cannon, but a maximum discharge, with a buildup time of 30" and a discharge time of 1", has an instantaneous power output of 75000 Terawatts: this means that, even with a low rate of fire, the peak power on the target is more than ten times the power of a Sharlin, while the enormous Mk X of the Tillmans (45 Megatons/discharge) and Mk XIII of the Centurions (65 Megatons/discharge) are weapons with a power level close or eventually superior respect to the weapons used by some of the First Ones ships, like the Shadow battlecrabs (in fact the aegis Mk V has yet a peak power that is superior to a Shadow battlecrab beam, even if a battlecrab can shoot continuously).
This "overkill" capability has a simple consequence: there is no defence. None of the ship of the Younger Races can survive this power, and even many "Ancients" could find nearly impossible to oppose an attack brought on with a G.O.D. cannon.

Actually, the models in service are the Mk IV (G.O.D. Satellites), the Mk V (Warlock class destroyers), the Mk VI (Nike class Cruisers), the Mk IX (Nova II Dreadnoughts), the Mk X (Tillman Heavy Dreadnoughts) and the Mk XIII, the most powerful, on the Centurion Class Dreadnoughts. Actually the new batches of the Warlocks and Nikes and the next batch of the Centurions, will be equipped with the E-1 variants of the Mk V, Mk VI and Mk XIII, that incorporates a fast discharge technology (Pulse Compression) that enhances the penetrating power. (Note: The Mk VI is a lightly shortened variant of the Mk V)

The first shot in combat of the G.O.D. cannons of a Warlock was fired in the "Strelas'tha" incident of 2262, incidentally aginst a "rebel" Minbari Sharlin, (see Strelas'tha incident dossier), while the first large scale operational use of these weapons was during the Drakh attack of 2265: the Mk III cannons of the G.O.D satellites were capable to nearly vanquish the attacking Drakh forces, even if this was not enough to avoid the spreading of the Plague nanovirus, while in that same battle, the heavy destroyers Warlock, Enchantress, Sorceress, Necromancer, Rhiannon, Persephone, Titans (Navy) and Styx (EFNI) fired their G.O.D. cannons against the warships of the Drakh fleet: The Aegis Cannons fired 72 double discharges and 69 hit the targets, obliterating them with a single shot. Until today, each time a G.O.D. cannon discharge has reached his target, it has demonstrated a terminal effectiveness, with a 100% kill ratio.

One of the newest developments in the weapon systems is the Fusion Pulse Cannon, a weapon outcome of the last advancements in the Gravitic enhancement of the fusion process. The buildup of the energy of the plasma bolt is obtained inside the barrell of the weapon, that is, by all the points of view, the matching of a Gravitic fusion reactor and a plasma pulse accelerator. The main advantages are the enormous power of a bolt, the high speed and the enhanced range of the bolt itself, and the relatively low energy consumption, while the disadvantage of such weapons are the weight, the bulk dimensions and the cost; the Gravitic Fusion Pulse Cannons have shown itselves devastating at the short and medium ranges, with terminal effects of a magnitude order highers than the ones of the classic Pulse cannons, and an impressive rate of fire.

The Hyach Spinal laser technology was acquired (salvaged) by the E.A. shortly after the Earth-Minbari war. It still remains one of the most powerful known raking/piercing weapons, with the advantage of being uninterceptable, but it is very difficult to integrate in an E.A. tech based ship, due to the power drainage and cooling requirements. The development of pulse/particle beams for the Omega class destroyers and of the G.O.D. particle cannon absorbed the bulk of the E.A. weapon systems r&d capabilities, so the reserach around the spinal laser went on slowly, until in the late 2250, when an old but effective principle was applied to the Spinal laser: a Q-spoiling device. This device converted the spinal laser in a pulse weapon, eliminating its raking capability. However, the single pulse of the Q-spoiling spinal laser allowed it to pack the same energy of a 6" full power discharge in a single 0.02" burst, with a magnificent piercing power retained at the maximum range. The weapon itself drained a lot less power in a controllable way (the power input efffects only the rate of fire, not the power of a single shot ), and developed less than a quarter of the waste heat of the original type, allowing a light and sleek overall installation. Unable to compete with the heavy particle GOD cannon in terms of raw power, it is instead a good choice to give a long range punch to new medium and light units, and can be retrofitted on older ships, at a fair cost, without overwhelming their power distribution plant.

The limit of the istantaneous power of a classic optical laser is set by the reflectivity of the two mirrors (aft and fwd) of the laser: part of the energy (light) treated by the laser is not reflected by the mirrors, but is absorbed by them; more powerful is the laser, more high is the absolute energy adsorbed by the mirrors. Above a given power level, the mirrors overheath and melt, or sublimate. The original Hyach spinal lasers, and the classic lasers used by the E.A. and by other known races used mirrors made of a tungsten alloy, with a complex cooling system. The actual Eart Alliance Q-spoiling laser utilizes mirros made of an inorganic liquid crystals polymer that has twelve times the reflectivity of the old mirrors, and twice the thermal capacity: this means that a Q-spoiling laser of actual production can manage 20-25 times the instantaneous power of the old lasers: this new technology, in conjunction with the Q-spoiling pulse compression principle, allowed to build a family of weapons with an inusitate piercing power, unmatched by any other known type of weapon of the Younger races. Obviously, this doesn't means that the Q-spoiling lasers are the definitive weapon: the high piercing power is not necessarily united with the raw destructive capability of a plasma weapon or of some types of raking weapons, like heavy particle beams or similar (*except for the A.M.S. T-1000 Q-laser of the Gladium Assault ships, whose extreme power induces different effects on the target, with high level of induced damages.).

In any case, a discharge of Q-laser is almost always able to pierce the armor of a target, and able to inflict heavy damage to any device or system directly on the trajectory of the laser inside the hull. Must be added that the actual models of Q-lasers, either the spinal and the turret models, have a fairly high rate of fire, and so, with a sustained ripple, are able to inflict a devastating cumulative damage. The weapon system (General Electric GAD 16-U) of the Nike Cruisers is based on this principle, and has proven itself extremely effective in combat.

Actually, the "Q-Lasers" are installed in a spinal emplacement on the
Nova Delta Dreadnoughts (A.M.S. QSL -2E), on the Lupo frigates (A.M.S. QSL - 3S) and on the Vigilante Patrol Corvettes and are proposed for the Omega. Some turret mounted types have been developed: the powerful A.M.S. QSL 2T Long Lance, designed for the Tillman Dreadnoughts, the A.M.S. QSL - 4T installed on the Centurion and the Nova II Dreadnoughts and the A.M.S. QSL - 5T proposed as a retrofit for the Nova Beta: they have a shorter barrel, a more compact cooling system, and a power of about 75% of the spinal models. The same cannon is available for spinal installation on lighter ships (A.M.S. QSL - 5S).

The A.M.S. T-1000 is a special purpose Q-spoiling Spinal Laser, whose length is about one kilometer: the details about this weapons are classified; it was developed in accordance with the specifications and under a contract issued by the E.F.N.I. to satisfy the requirement for an uninterceptable and unshieldable weapon with extreme piercing power, greater than the ones of the Mk XIII G.O.D. cannons and of the Quantum Discharge Weapon of the Victory Class ISA Destroyers. The only detail that can be published is the declaration of an official speaker of the Earth Alliance - "The T-1000 can penetrate more than a mile of solid steel". Further details will be published when the Joint Staffs of the Earthforce Navy will allow the disclosure/declassification - We apologize for this necessary censorship. - The T-1000 is the Main weapon of the Gladium Class Heavy Assault Vectors.

The General Electric Gad 16 U is a weapon that is non conventional respect to a class of weapons, the Q-lasers, that are non conventional in itselves.
This compact system was designed in the late 2260's taking into account the particular needs of the
Nike class cruisers: the concept of the GAD 16 U is based upon the saturation of a target with highly piercing laser shots: all in all, an engagement is not based upon the power of a single discharge, but upon the cumulative effect of many weapons firing on a same area.
At 800 shots/barrell/minute, an engagement, that usually is 1-1.2" long and carried on with three or four turrets means that a target can find itself with an area of about 50 or 100 meters of diameter with something like 500 or 600 holes of a span of diameter and some tenths (or hundreds) of meters deep through hull and internal system: this has repeatedly shown to be well enough to "sing the last song" to a Drakh cruiser.
While not used on other ships, and while being really somthing "strange" in the weapon systems panorama, the GAD 16 U is someway a masterpiece of optics and high technology, but there are even the "versus" arguments: small dimensions and light weight, high rate of fire, impressive piercing power, awesome accuracy and reaction time, while giving the interesting outcomes exposed above (and, BTW, the "Terminator Cannon" is even an excellent antifighter weapon) are paid in terms of cooling needs, maintenance, and, mostly, high costs.
In fact the whole Nike project is something ahead of the EA standard technology, and even the exceptional combat performances has not avoided tho the GAD 16 U and to the Nike battle cruisers to become "special weapons" for special purposes: at the end, a Nike costs something like 1.5 Warlock Destroyers, and this means something.

The Beam/Pulse weapons are a family of complex, effective and versatile system that allows the use of the same barrel both as a Plasma or as a Pulse Cannon and as an heavy particle beam. This technology, exclusive of the Earth Alliance, that allows the use of a same weapon for two completely different modes, Plasma Pulses (Higher power and damage), and Particle beam pulses (Higher range) has relevant tactical advantages and has given excellent proof with many products; the dual bolt/beam technology is one of the better protected Earthforce secrets.

The pulse-particle beam cannons of the OMEGA type are an hybrid particle beam weapon, like the Centauri and Narn main particle beams, but in the higher range of power output, with an added plasma bolt capability for short range antiship warfare and, in high rate of fire pulse mode double themselves as anti-fighter defence and as interceptors. All this is packed in an extremely compact turrett, whose dimensions can easily mislead the valuation of the real power of the OMEGA, while in fact are the outcome of years of research, developement and hard design efforts.
The OMEGA cannon is one of the most effective and powerful weapons known:as said it can operate in plasma pulse mode (medium rate of fire, high energy bolts), in interceptor mode (high rate of fire, medium energy pulses) or in particle beam mode; in this case, the emission is a beam of high energy particles (Ionized Cesium atoms) beam, that is electrically neutralized just before the exit from the barrell: the fire mode, in this case, can be continuous (Raking mode), but the standard mode is a series of discharges of 0.5-1.2 seconds of duration, that allows a peak power double than the continuous beam emission, and that allows, besides a raking effect, an excellent penetration.
The design of the weapon allows an instantaneous switch between the pulse and the beam mode: at medium and short distances this capability can be exploited in the "dual fire" : while an high power discharge is built up in the accumulation ring, the barrell can operate in pulse mode without interferences, and so it is possible to fire upon a target with a continuous bombardement of three-pulses plasma bursts immediately followed by a beam discharge, by another pulse burst and so on: this type of attack is something that very few targets can hope to survive

In the days of its inception and along all its service, the Raytheon OMEGA cannon gave to the Earth Destroyers a firepower that was a quantum leap respct to older designs, placing them at a level of excellence among the warships of the Younger races: the pulse mode, at short distance, allowed effects on the target that, while not exceeding the performances of the broadsides of a Nova, were anyway impressive. The heavy particle beam mode gave an unprecedented effectiveness at all the ranges, matched with an easy targeting and to a penetration on the target that is at a level on par or superior to almost all the capital ships of other alien powers, and was one of the resons that made of the Omega destroyers one of the most effective and deadly warships ever seen: the Omegas, thanks to the combination of firepower, protection, sturdiness and an overall equilibrated design, have proven themselves to be at least on the same level of the extremely advanced Drakh cruisers, superior to all the other capital ships but the Minbari, and have been a key factor in the survival of the human race and in the victory of the ISA against the Drakhs.

The SUPEROMEGA cannon is another Masterpiece, as was at the time of his inception the OMEGA heavy Particle/pulse cannon.
This new weapon is exactly the conceptual equivalent of the Omega cannons, I.E. a same, compact weapon able to treat either plasma discharges and a powerful, long ranged particle beam. Given the success and the effectiveness and operational versatility of the original system, the R&D team of the Raytheon Co. attempted a further step, the matching of the Ion Bolt technology of Centauri derivation, and the "Slicer beam" technology of the "Shadomegas". The problem was that all the units of the "Shadow beam" were lost, but in this occasion the Technical Division of the EFNI was really helpful: the technical branch of the Service was able to collect, organize and salvage a large amount of informations, thanks to his investigations and thanks to testimoniances and interviews with the survivors of the "Omega-X" personnell and of the technical teams that followed that project.
A five years research program, started in the January of 2269, produced a compact, extremely powerful and affordable weapon of about the same dimensions of the OMEGA cannon: the capabilities are impressive, given the piercing and explosive power of the large calibre Ion bolts of this new weapon, and the penetration and raking capabilities of an high density, high amperage antimatter beam. In the Ion pulse mode, this weapon operates in the same way of the Ion bolt weapons (see "Ion bolt weapons") - In the Antimatter beam mode, it operates as an high efficience particle accelerator, as the original OMEGA cannon, but the feeding system is totally different: instead of the original heavy particles accumulation ring, there is a double ring that operates in two stages: the first stage acts as an antimatter generator, the second ring, that is the feeder of the cannon, is an antimatter accumulation ring. The same process, in the original shadowtech weapon, was entirely accomplished in the barrell of the weapon, but the rate of fire was low, the barrell, heavy and bulky, induced aiming problems and slow tracking of the target, while the new feeding system is simpler, allows more power and a higher rate of fire, and it's a lot more affordable and resistant than the original coaxial feeder.
The SUPEROMEGA actually is standard issue for both the upgraded
Omega Brightwarrior destroyers and for the Nova Delta Brightwarrior DN.
Some unclassified data are availble, but other data and internal devices are highly classified, and cannot be published - We sincerely apologize to the public for this necessary limitation.

Both the OMEGA and SUPEROMEGA are available even in a "spinal" fixed variant, characterized by the large magnetic deflector at the bore of the barrell, that allows the steering of the beam and of the bolts projected in order to allow to aim the fire against a target. This configuration is overall equivalent to the turret variant, with some minor penalties in the effective range and the add-on complexity of the deflector.

The Raytheon WI 999 is one of the two hybrid ion weapons actually in use, the other being the Raytheon SUPEROMEGA. An outcome of the Brightwarrior project, it was designed to give to the Warlocks and to the Nikes the superior performances of the Ion cannons matched with the long range of the particle beams; it was indeed an excellent weapon, but Earthforce, with some valid reasons, gave its preference to the MI 190 Ion Cannon, that allowed similar performances in almost all the tactical situation except the longer ranges, but at a vastly lower price and without the need to replace the whole turrets. In fact, the long range arms of both Warlocks and Nikes are the heavy particles G.O.D. cannon, the missiles and the Starfuries, and so the beam capability was not really needed. This accurate and powerful weapon, anyway, due to its operational flexibility in some particular tactical situation, has been chosen by the EFNI Naval Service as a standard issue and it is the equipement of the E.A.S.Styx and, funding allowing, will be eventually embarked even in the Nike cruisers of the EFNI.

During all his space expantion history, the Earth Alliance Navy based his anti-fighter/anti missile defence on two main systems: the Interceptors/energy web, able to disrupt the incoming fire of Plasma bolt and particle weapons, and to intercept and destroy missiles and fighters at close range, and a powerful covering of fighters. This combination proved herself extremely effective through the Dilgar war, and in the skirmishes during the whole period until the Minbari war. During this devastating conflict, both the Nova and, in a lesser measure, the Hyperions, found themselves ill-equipped against the Nials fighters, almost always presents in numbers larger than the earther Starfuries, and qualitatively well superior to the fighters of the E.A. In many occasions, units that could survive a combat with the Minbari were destroyed by the implacable attacks of the Nials, lacking a weapon system more powerful and ranged than the interceptors, but quick and small enough to deal with the nimble and fast fighters.

The technological answer was the pulse/particle weapons, systems able to operate in dual mode, with a particle beam for the higher distance, and a fast rate of fire plasma pulse mode for the medium and short range covering. The very first of these systems was the Walther-Raytheon WR 1000, that saw the combat in the final weeks of the Earth Minbari war, and proved itself really more effective than the older systems, able, in some measure, to oppose the overwhelming superiority of the Nials.

This early weapon evolved in the more powerful Walther-Raytheon WRK 1005, that became the standard equipment of the Omega destroyers and of many more new E.A. Units, a weapon able not only to offer an extremely effective anti fighter capability, but able, at the medium to short ranges, to inflict heavy damage at larger warships. Its double pulse/particle beam mode allows a flexibility and performances unmatched by any other former design. The Walther/Raytheon WRX 1028, actually embarked mainly on the Warlock Destroyers and on the newest units, is a smaller design better suited to the anti fighter/anti missile defence, due to the higher rate of fire. Both these weapons will remain in production for long years, thanks to their effectiveness and polyvalence, and are integrated in the Interceptor Grid Mk II and Mk III.

The Plasma cannons and the Plasma pulse cannons have been the mainstay of the fleet arsenals from the dawn of the Earth Alliance expansion beyond the solar system, through the acquisition of the pulse compression technology from the Dilgars. The Plasma weapons are a simple and effective concept: high temperature plasma (helium collected from the fusion reactor of a starship, but even other gases like Xenon or argon, used by the Earth Alliance, ionised and heathed inside the barrell), is accumulated in a containement chamber inside the weapon. Once the necessary Plasma charge is accumulated, the "bolt" itself is compressed, to allow the maintenance of concentration for a given time, released in the barrell of the weapon and accelerated by elctromagnetic fields. The energy accumulated in a bolt is impressive, and, until the bolt begins to decay and dissipate, it is able to inflict devastating damages, and allows high penetrating power. The main disadvantage of the plasma weapons are the short range and the energy and plasma drainage from the main reactors. The great advantages are the piercing power and the ability to release on impact a large energy pulse, able to damage either the outer and inner structures of a target due both the thermal-ablative effect and to the concussive-explosive effect of the Plasma bolt: this last effect is very important even in regards of the penetration mechanism: when the plasma bolt impacts an armour, it vapourises the material of the plate, and this generates even the equivalent of a powerful explosive blast, and a shockwave through the armour.
This "explosive" effect can be powerful enough to collapse mechanically and breach through armour and hull structure of a ship.
The EA armours are less sensitive to this effect due to the high mechanical (and thermal) resistance of the composite materials employed, and to the effective compartimentation of the hulls, but the crystalline armours, while proportionally equally or even more effectives against beam weapons, are more brittle, and much more subject to the "concussive breaching" of the bolt weapons.

The Pulse technology is essentially a series of systems that enhance the plasma bolt compression and shaping, giving a better piercing power, and increasing slightly the range, and a fast feeding system that allows to increase up to an order of magnitude the rate of fire of a plasma based weapon.

A classic example of heavy plasma weapon, the LPA 1000 was the standard equipment of the Rocketdyne Nova DN of the Beta series, and was born on the guidelines of all the Nova project "...so powerful to defeat the main capital ships of the most advanced races known".
Limited in range as all the plasma based weapons, it set new standards both for the design and for the inusitate power of the single bolts. Initially deemed as a surdimensionated and power thirsty system, it proved itself excellent, someway decisive during the Dilgar war and was one of the few effective weapons during the Minbari conflict, being able to cleanly bore through the armor of the main hull of the Sharlin cruisers. The piercing power is high, but still confrontable with the smaller systems used on the Hyperions; the explosive/concussive effect at the impact was instead, and still is, a punishment difficult to sustain even for the most advanced combat ships, as was also seen during the Drakh war, when the old Novas were able to win the artillery duel against many enemy warcruisers with their devastating broadsides.

The M152 was a relatively light weapon developed in the wake of the Minbari War as a new equipement for the Hyperion cruisers.

The HLPA 2011 is the last evolution of the Westinghouse "1000" series heavy plasma wepons. Large, heavy, complex, extremely powerful, it exploits the "Phased Plasma" technology, that ensures a superior density of the plasma bolt, with enhanced penetration and superior concussive effects.
The HLPA 2011 is one of the most destructive weapons actually used on the EA warships, namely some Omega Gamma and, mostly, the
Nova Delta Dreadnoughts. The HLPA 2011, during the Drakh war, has shown to be so accurate and potent to become one of the most thrusted systems for many years to come, and worthwile of further developments.

The Westinghouse "Mjolnir" is the very first heavy plasma mortar, ancestor of the plasma pulse mortars of the actual generation. Designed in the late 2210's as heavy antiship weapon, it entered in service in the 2225, with the Nova class Dreadnoughts. It is still today used on many classes of warships from the destroyer to superior cathegories.
The Mjolnir, even if relatively lightweight and simple, is a large and bulky weapon, short ranged and power thirsty, that has its best carachteristics in the high power and in the accuracy. The rate of fire is acceptable, the piercing power is good, while the concussive and explosive effects on the target are impressive. Is due to its short range effectiveness that it is still today used on large part of the ships of the fleet. Due to the dimensions, the Mjolnir was never fitted in a turret mount: it is installed in a fixed twin mount under the bow of the Novas and Omegas, in a quadruple mount in the bow of the Tillman heavy Dreadnoughts, on the sides of the bow of the Nova II, and on the sides of the hull of the Warlock Destroyers. During the early 2250's was developed a variant of the Mjolnir, the EM2 , more powerful and with an articulated mount, to be used as antiship battery in fixed space installations, like shipyards, arsenals, orbital outposts and stations.
It was the main antiship defence weapon of the M3xx series orbital outpost core stations and of the Babylon series diplomatic stations.

The actual Plasma Pulse Mortars are the last developement of the pure plasma weapons. Employing the pulse technology and a new "flat" barrel design that improves the penetrating power, they are among the most effective weapons actually used on the Earthforce units.
The most distinctive characteristics of this type of design are the extremely high power respect to the light weight and the simple construction, that allows high production rates, low cost and an exceptional cost/effectiveness. Since their inception in 2268, the plasma mortars, employed both on the
Lupo Frigates (HP-01A) and on the Vigilante Patrol Cutters (HP-08A), have proven themselves an excellent, affordable weapon.

The Raytheon M111 was born as the standard weapon of the
Warlock destroyers, and equipped even the Nike cruisers and the Tillmann Dreadnoughts.
Heir of the developement work made on the OMEGA cannons and on the HPPA type 1505, exploits totally the pulse technology, with an high level of plasma pulse compression (Phased Pulse) that, matching high bolt power and high rate of fire allows a superior penetration in a compact and lightweight design. Until the inception of the ion weapons, the M111 had very few opponents in terms of short and medium range effectiveness.

The WRX 1028 is a close-in defence system, base of the Mk III interceptor grid and an excellent antifigter/anti missile weapon. It renounces to the polyvalence of the WRK 1005 (it has not a particle beam capabilty) and to the power of the single shot in exchange for an awesome rate of fire, allowed by the Gatling design: the WRX 1028 has a six barrell bundle operating in a way similar to the Copeland-Westinghouse GAU-112 U "Warhammer" used on the Thunderbolt.
The rate of fire ensured by the Gatling pulse technology allows some extreme performances, like an antifighter "firewall" barrage mode, with area saturation patterns.

The mainstay of the Centauri artillery weapon systems, as well known, are the Ion weapons. Beyond the Centauri, only the Minbari, among the Younger races, shared the conceptual know-how about this type of weapons, even if only the Centauri evolved this tecnology to an unparalleled effectiveness, while the Minbari abandoned the concept hundreds of years ago.
The Ion Cannons are the further step after the pulse/plasma weapons: the "Ion" bolt itself is of the same physical nature of the plasma ones, but the Centauri are able to obtain extremely powerful and dense bolts with exceptional destructive power, either in terms of penetration and raw energy release on the target, and ranges well beyond the usual limits of the bolt weapons, due to the high speed of the ion discharges that the Centauri were able to obtain. The advantages of this type of wepon are clear: the high penetrating power matched with the explosive effects and the impulsive high energy release of a powerful plasma cannon, with relatively contained power feeding, and a range confrontable with the most common beam weapons.
Earthforce developed an interest in the Ion bolter technology after the "Thirdspace Aliens" incident of Babylon 5: the Heavy fighters (class "3 alpha") utilized by the Alien race are protected by a type of "energy field/energy shield", able to resist the fire of the plasma bolters of the fighters, and in some degree the fire of the particle weapons, but not sufficiently powerful to survive the fusion pulse cannon fire of the Whitestars: in case of an engagement with such adversaries, the antifighter weapons (WRK1005) of the Omega destroyers and of almost all the E.A.ships could be ineffective, while the powerful Ion weapons of the Vorchans have power and rate of fire well in excess to destroy the Class 3-Alpha targets with a single hit. the Twin Ion array of the Vorchans has such dimensions to barely fit on the mountings of the WRK1005, so it would be an excellent alternative for an upgrading of most part of the Earthforce Space Fleet.
There was an obvious problem: the Centauri, given the stressed relations with the ISA in that period, were all but available to give access to one of their most relevant military technology. Even the rare relics of damaged or destroyed Centauri vessels didn't revealed the true nature of the Ion technology, Neither to the E.A., nor to the other members of the ISA.
In the Wake of the "Damocles" initial report about the menace of the Thirdspace Aliens, Earthforce pushed the research about some key technologies: in this particular area, the EFNI was able to gather fundamental informations that allowed the EFRAD to break the curtain of the Ion technology, and to develop a small family of weapons with sufficient power to ensure the single-shot kill capability against the class "3 alpha" target for the smaller weapons, and the penetratione of the gravitic shield of the capital ships for the larger cannons (Raytheon M190, Raytheon SUPEROMEGA), thanks to the high energy density and the high speed of the bolt.

The Ion Weapons technology is refined, and based upon brilliant principles: outside the barrell, a "Ion" bolt is simply a neutral plasma bolt, not conceptually different from the ones of a plasma or pulse weapons, even if much more dense, powerful and fast, but inside the weapon the processing of the bolt is extremely different from the classic plasma weapons. First of all, the Centauri developed a particular magneto-gravitic containement field extremely powerful, and conceptually assimilable to the fields of the Gravitic striction fusion reactors and weapons, but generated by a very compact device and with an extreme density. This allows to process a large quantity of fully ionized heavy atoms, and to pack them in an very dense form in the main chamber of the barrel; the bolt is easily accelerated along the barrell of the weapons (a simple, higly efficient LINAC), thanks to his excellent electric charge/mass ratio, that allows high speeds in relatively short barrels. At this point is obtained a dense, fast, extremely energized plasma bolt, that, because of his high positive charge, would dissipate in a few hundred meters...except for the fact that the Centauri were able to develop a charge neutralization system that injects a well calibrated free electron multiple stream in the muzzle of the weapon, and neutralizes the bolt, that, from this point, works like a normal plasma bolt. The most technologically demanding devices of such a weapon are the containement/compression fields, and, mainly, the neutralization system in the muzzle of the weapons, with its fast operating and self calibrating synchronization circuits.

The EFRAD, in conjunction with the research teams of the most important weapons design companies, was able to develop, validate, and produce two weapons that enable a quick and simple (and expensive, by the way) upgrading of the antifighter defence and of the Interceptor Grid of the Earthforce ships. The application of the technologies developed by the Earth in his double function weapons (particle/bolt and particle/plasma), and in the gravitic fusion plasma cannons, allowed to quickly develop a proprietary Ion technology.

One of the considerations that induced almost all the other ISA members (Except obviously the Minbari) to give up about the Ion technology research and development, was the fear for the high energy requirements of these weapons: in fact, this is not a correct approach. A weapon, except the internal fusion fed weapons, has a power output directly related to the power input: the Ion Cannons have an high energetic efficience, and the exceptional power of the Centauri weapons is due to the large power availability of their vessels.

Correctly, Earthforce wasn't so much concerned: the E.A. warships are notoriously slow, but this is not due a low power availability, it is related to the high mass of all the heavily armored E.A. units: all the Earth warships are very heavy for their dimensions, but with powerful engines and reactors, and a large power availability, so they are well able to manage the requirements of the Ion Weapons.

The actual production systems, (that have been developed as interceptor-capable) are the Raytheon SUPEROMEGA (see chapter
"BEAM /PULSE WEAPONS"), the Walther-Raytheon WRI 2028, the substitute for the lightweight WRX1028, the Raytheon MI 190, that is designed to fit into the barrel holders of the M111 plasma/pulse cannon turrets of the Warlocks and of the Nikes, and the the twin barreled Westinghouse-OTO Melara WM 203 that has been designed to be the most powerful installation compatible with the WRK1005 emplacements of the Omegas and of the units that actually employs this weapon. This last technical choiche was not an accident: the WM203 is roughly equivalent to the Tavari ArmCo VOXX twin turrett of the Centauri Vorchan: this means that, with 12 emplacements, an Omega or a Nova Delta can develop a firepower nominally equivalent to six Vorchans: given the firarcs and the position of the E.A. weapons, a single target will be always subject to a firepower equal to the one of three/four Vorchans, and this only with the secondary weapons! So, while the antifighter/antimissile and the interceptor capability is not only retained, but vastly improved (with some overkilling, if this expression has some conceptual validity), the antiship firepower is vastly improved, and made of the various units utilizing this weapon (Omega, Nova Delta, Nova 2, Lupo) a furtherly more dangerous challengher.

A collateral information: after the liberation of the Centauri Republic from the Drakh infiltration, and after their rejoin of the ISA, the Earth Alliance restarded the traditionally close and friendly relations with the Centauri Republic.
One of the first discussions required by the Republic to clarify the "Ion Technology situation" led to some interesting consequences: first of all, The Earth Alliance signed a non disclosure agreement, to keep the secrecy about this technology; the Earthforce procurement agency paid the Royalties for the utilization of the ion technology, and , in exchange, the House Tavari Armament Company, builders of the Vorchan Class Warships and traditional suppliers of the Centauri Navy, became the first alien company to be listed in an Earth Alliance stock exchange (HTAV.C - NASDAQ).

Railguns are potent weapons, and have been for a long time, until the Dilgar war, a masterpiece of the Earth Alliance technology. Conceptually simple, it is just a linear electric motor that accelerates a conductive projectile, it requires very good material technology to became a really operative and effective weapon. Since their inception they were well liked because of their awesome piercing power and affordability, and the ability to destroy enemy armors and systems. The railguns of the first generation were partially replaced in the favour of the Earth Alliance purchasers by the now available pulse weapons, that allowed a major theorical damage capability without ammunition supply, even with a lower piercing power. The Minbari War was an hard teacher, but in that desperate days, the Artemis Beta "Railfrigates" were among the few warships able to inflict heavy damage to the Minbari units, in the occasions when they were able to survive the firsts seconds of the battle and open fire against the enemy. The railguns of that period were low rate of fire weapons (10-25 rounds/minute), with heavy aluminium projectiles.

In the recent times, from the immediate aftermath of the Minbari war to the developments of the mid 2250's, a new generation of railguns has started the resurrection of this weapon system: the main differences are the projectiles, that are no more a large aluminium slug, but a complex composite hard core penetrator, the APHCLR shot, accelerated in a ionized helium "bubble" wrapped around the projectile itself that eliminates any friction between barrel/rails and projectile, and the rate of fire that in the last products, thanks to a new revolver feeding system and to the"frictionless" projectile, is an awesome 2600 rounds minute for a twin mount, with a 16000 rounds carousel magazine. The piercing power of the small 127 mm penetrator used by the "Super Rapido" series railguns is well enough to pierce all the known hulls, even the ones belonging to the most advanced races, and the rate of fire allows a devastating saturation fire.

* APHCLR=Armor Piercing sabot Hard Core Long Rod - The actual railgun projectiles, as can be seen in the Technical Schematics, are a composite shot that has a lightweight external frame, that is essentially the "armature" of the impactor and its "engine" inside the barrel. The Frame, or "Sabot", holds along its centerline a rod made of an iridium/cobalt based alloy, extremely dense (about 20, so 2.5 times the steel), slender and though, that represents the 85% of the mass of the projectile: at the impact the external sabot virtually sublimates, with a relatively low penetration and a craterization of the external face of the armor, but the kinetic energy of the rod is so high and so concentrated on a small area, that this inner core is virtually unstoppable.
The subcalibre principle is well known, at least as a concept, from the mid XX century and is not strictly necessary because even the older "solid" shots were virtually always capable to bore through the armors of the targets, but the new "subcalibre" scheme, while more complex and expensive, ensures that the impactor travels well deeply through the hull, the systems and the structures of the enemy units, and allows to produce enormous internal damages: everything on the path of the penetrator is destroyed, frequently along all the width of a ship.

The TG4 was the first "new generation" railgun, literally built around the APHCLR ammunition of 203mm (8") of calibre. While lacking the revolver feeding system, and using a classic direct ramming sledge, that does not allow the superior rate of fire of the newer models, is indeeed an effective weapon, whose main merit is to have traced the path of new technologies and concepts. Its fast, massive projectile has an impressive piercing power, and the weapon is extremely accurate.
Standard equipment of the EFNI units built in the 2250's (Nova-N and Hyperion-N), has proven its effeectiveness in many occasions, even during the Drakh war.

The 127mm (5") railguns were a lucky development aimed to allow a superior antiship effectivenes to medium warships against well armoured but highly manoeuverable targets. Indeed, even if relatively small, the lightweight and elongated 127mm APHCLR projectile has a terrific piercing power, and this series of railguns is the first to use the "revolver" feeding principle, that allows a rate of fire of more than 1200 shots minute (20 shots each second) for each barrell.
Largely employed on the Lupo Frigates and Nike Cruisers, but embarked even on ships of the dreadnought/destroyer class, the matching of high penetration, accuracy and high rate of fire makes of these railguns a devastating short range weapon.

For all its history, from the beginning of the space combat until the present days, Earthforce has always had an articulated inventory of missiles, that can be divided in two main breeds: the endoatmospheric missiles, mainly tactical weapons, anti-aircraft (either air to air and surface to air), or ground attack weapons (air to ground and ground to ground), and the exoatmospheric missiles, that were subdivided in antifighter/antimissile, bombardement and antiship roles. The endoatmospheric missiles are out of the objectives of this paragraph, that instead presents the last evolutions in the exoatmospheric antiship missiles.
Missiles are not equally used by the space fairing races: Earthforce, Centauri and Drazi Navies all uses at least one type of missile, if not more, while Minbari, Narn, Vree and Brakiri don't believe in this type of weapon: Minbari and Vree relate on their technologycal edge in the areas of propulsion, weapons and electronic warfare, and the Narns, having their historical enemy in the Centauri Republic, have not been able to develop guidance systems unjammable by the advanced Centauri electronic countermeasures.
Antiship and antifighter missiles were an important part of Earthforce weapon systems until the Dilgar war: the tecnologycal superiority of the Dilgars was not enough to render uneffective Earthforce missiles launched in swarms, but was enough to proof these old generation weapons not so effective, respect to the combination of heavy plasma artillery and Starfury fighters.
The lack of cost/effectiveness during this war, in combination with the efforts in development of the new generation Plasma Pulse Weapons, brought a lack of interest in the evolution of old weapon systems: Missiles and railguns were the victims of the budget relocations, and Earth Alliance faced the Minbari with missile systems of a generation dated before the Dilgar war, and based on active radar homing+direct data link guidance principles: obviously, they were almost useless against the Minbari. The only hit of a missile warhead during the Minbari war was achieved by warheads removed from the missiles, and used as hand-laid mines in the Asteriod belt to destroy the Drala-Fi (Shargoti class battlecruiser).

A more realistic approach to the missile utilization followed the war, and started from some fundamental assessments:
1-The basic radar homing guidance principle alone is effective only against less technologically advanced foes: new (or old, but different) guidance principles must be used.
2-There is not a technology able to obtain the optical and infrared invisibility.
3-A thermonuclear warhead is effective against an heavily armored ship (particularly if equipped with refractive crystalline armor) only with a direct impact or with a very close range detonation. In this case, the ship is or destroyed or crippled.
4-A Starfury, with a maeneuvered approach trajectory, can close the distances until to the physical contact with almost anythting, if it's able to avoid the pursuit of enemy fighters. Consequence: a saturation swarm attack of very maneuverable and very fast medium range missile, should be able to avoid partially enemy fighters pursuit and to survive CIWS fire long enough to insure a very probable direct hit.

From these statements were devloped some new families of missiles: the most important of them are the Rayhtheon "Blue Phoenix" polyvalent heavy missile, the Sandia "Shillelagh" antiship missile and the A.M.S. "Viper" missiles. The most important difference between these weapons is that the Shillelagh and the Viper are single warhead missiles (the shillelagh is a medium sized shipborne missile, while the Viper is a relatively small missile utilized by the Starfury fighters of the Aurora SA-23-G, Badger, SA-26-A Thunderbolt, and SA-32-A Firebolt models), while the "Blue Phoenix" is a very large missile, equipped, in his antiship variant, with seven independent terminal attack vehicles, that are, from all the viewpoints, smaller missiles with high speed and extreme maneuverability. The first operational destination of these missiles was the Global Orbital Defence Satellite grid: The G.O.D. sats have a large number of launch silos for these missiles, intended for saturation "swarm" attacks, and the missiles itselves are equipped with a totally redundant guidance and homing system, that, while retaining an improved radar homing system, is centered upon an array of optical sensors, operating either in the visible light, ultraviolet and Infrared bands, with advanced image recognition and data fusion systems and algorithms, that render very impervious to the jamming/cloaking the guidance system. Both the Shillelagh, the Viper, and the "Barracuda" terminal attack vehicles of the Blue Phoenix are equipped with plasma thrusters that enable quick random maneuvres to dodge the antimissile weapons fire, and an exceptional maneuverability. The propulsion systems of these medium and short range missiles are centered upon high thrust, short endurance Ion engines, ables to achieve accelerations of 70 to 850 "g's" for a few minutes*.

Operational use

Operationally, the first use of these missiles was during the Battle for the Earth, when the Earth Liberation Forces faced the Clark's Regime, and were fought by the missiles of the G.O.D. Satellites. The ripples of missiles, even if destroyed in the percentage of 70/75% by the Starfuries, the Whitestars and the Nials, and furtherly intercepted by the close-in weapons of the Liberation Fleet, were able to get many direct hits against the ships, included seven direct hits against the Sharlin Cruisers that supported the Earth Fleet: none of the warheads detonated, avoiding further losses of human lives, because the arming codes of the thermonuclear warheads were altered and disabled by a loyal intrusion agent of the E.F.N.I.
The first ship class to employ these new, effective missiles, in an installation able to insure a saturation attack, was the Warlock destroyer, with his 12 "Blue Phoenix" and 16 "Shillelagh" launching silos. The first use of this weapon was in the
"Strelas'tha" incident , when the second of the three rebel Minbari cruisers belonging to the "Tragati Fleet" met his destiny, trying to ambush the Warlock Destroyer "Sorceres" on border patrol duty: the Minbari ship hit first, but the special armor of the Warlock contained the damage, and the E.A. unit was able to reply to the fire with the railguns, and a ripple of the Warlock's missiles, and in this occasion the warheads were armed: one "Shillelagh" missile and at least four "Barracuda" terminal Vectors achieved a close detonation, incapacitating the minbari Cruiser that was destroyed by a G.O.D. cannon discharge. Historically, and laying a curtain of discreption about the politic wake of the incident, this was the first time an Earth Force Warship survived an One-to-one, open space engagement with a Minbari unit, and, furthermore, won the fight, even if damaged.
The missile systems of the Warlocks in the evolved variants Block IV-A and Block VIA and -Doperated with all their devastating power against the Drakhs, in the "Second Line Battle" of 2266, and were instrumental in the destruction of the Drakh warfleet.

*The Viper has a solid propellant, Magnetoplasmadynamic engine, simpler and smaller than the Ion engines of the larger missiles.
