SHARLIN WARCRUISER
The Sharlin, and its heir, the Shargoti, are the backbone
of the Minbari Navy since more than 800 years ago; The first
series of Sharlins, the Sharlin-Haza, entered in service about in
the 1450 A.D., while the Sharlin is an improvement dated back to
the late XIX century, and the larger and more powerful Shargoti
is relatively recent, a design of the late 2100's. The Shargoti
is the only ship of the family in actual production, and are
available more than 900 of them. The whole production of the
Sharlin family amounts to a total of a few less than 4400 ships,
but about 800 of them have been decommissioned or were lost in
service. The Sharlin family (Upgraded Sharlin-haza, Sharlin and
Shargoti) is actually (2280) in service in more than 3400 units,
representing the maximum naval power of this sector of the
Galaxy. In the present essay the reference unit is the Sharlin,
but are provided even the data for the Shargoti, that has
replaced the Sharlin in the shipyards since the 2238.
The Sharlin is a conceptual derivation of the Tinashi Haza -
Tinashi frigates (or cruisers)
used by the Minbari Navy in the "Ancient War" fought
against the Shadows in the years around the 1250 A.D., and
developed their architecture and their technology, in an
evolutionary more than revolutionary way, in order to overcome
the limits shown in the operational use by the older ships, and
produce a warship capable to fight with superior effectiveness
the Shadow capital ships (Battlecrabs). Almost all the design of
the Sharlin is centered upon this driver concepts, and the
outcomes were an enormous firepower and an exceptional strategic
mobility, obtained essentially thanks to the high average speeds
attainable in the hyperspace thanks to the advanced, low fuel
consumption propulsion system.
The Sharlin is a large, powerful ship, more than 1500 meters long
and 1700 meters tall, with a mass of about 55 millions metric
tons, a basic crew complement of 130, and overall performances
and effectiveness that place it well above the typical capital
ships of the Younger races. The architecture of the Sharlin is
clearly structurated on three main elements: a main hull, that
holds the crew and the primary systems, a large rear fin that is
the main gravimetric drive that generates the thrust (in fact,
the "pull"), and three relatively smaller fins, one
dorsal and two ventrals, that have installed at their tips three
secondary gravimetric projectors used for the manoeuvres through
the warping of the main gravimetric field.
The hull is a monocoque spaceframe, made of a reticular structure
of advanced metallic alloys reinforced with chrystalline fibres,
lightweight and of adequate strength, that holds the main systems
and the crew stations in combat conditions, the fins are a
conventional torsion box structure of the same material with
internal ribs and stiffeners.
The passive defence is based upon materials and concepts deeply
differents from the human design. The Main hull, very well
protected against the fire of beam weapons and energy weapons, is
heavily armoured with a stratified armour of polychrystalline
mesh and heavy refractory alloys, while fins and gravimetric
projectors are lightly protected, to allow a good efficience of
the gravimetric propulsion system and to avoid an excessive
growth of the ships's mass. The Minbari armour is conceived to
oppose the Shadow weapons, and the whole design is developed in
order to ensure the protection of crew and main systems against
the fire of the shadow fighters and auxiliary vessels, and to
allow a certain level of survivability, at least at the long
ranges, to the main beam weapons of the Shadow battlecrabs.
The Sharlin Warcruisers have neither an equivalent of the E-Web,
nor an interceptor grid (even if the gravimetric field generated
by the propulsion has a certain dissipative effect against the
pulse weapons), but their passive defence (as the ones of all the
combat capable Minbari ships and crafts) is supported by the most
powerful and effective electronic deception and jamming system
known, the "Stealth device", capable to avoid a
positive lock on from all the known electromagnetic scanners and
targeting systems (radar and microwave based) in use, at least
among the Younger races, and that is a determinating advantage in
combat, allowing to the Sharlins to fight at long and medium
distances with all their firepower with a virtual immunity from
the enemy fire. As said, the gravitic tidal effect generated by
the propulsion system provides even a secondary dissipative
effect against the plasma based weapons, but its effectiveness is
limited in respect to higly coherent plasma bolts, or against
shots fired at close distance.
The power generation system and the propulsion system, the
"Stalasha" drive, is an integrated design of three
gravitic enhanced fusion reactors and a main quantum singularity
reactor that generates the bulk of the power, while the fusion
reactors are used to start the quantum reactor and as an
auxiliary power source in combat situations. The power is
produced thanks to a grid of high efficiency magnetoplasmadynamic
generators placed in arrays along the flanks of the upper and
ventral fins, directly fed by the plasma tapped from the fusion
and quantum reactors, through channels running along the fins.
This system, even if large and expensive, allows a good degree of
redundancy and damage tolerance thanks to the distributed
architecture. The power output, fully available in the
distribution grid* is around the 350000 Terawatts, about 2.5
times the total power output of an Omega
Brightwarrior, more than three times a Nova DN, and this
enormous power, by the way, allows even to strongly cut down the
recharge time of the jump engines.
The gravimetric drive propulsion is the most powerful known among
the Younger races (the enormous rear fin of the Sharlins is the
visual evidence of how powerful this drive is), and allows good
acceleration performances regardless the high mass of this ship,
more than 3.5 g's, and, while power thirsty, has the classic
advantages of the gravimetric drives that, not needing propellant
reaction mass as the Newtonian engines (like the plasma and
particle/ion engines) allows enormous endurance and range, and
very high attainable speeds, given that the maximum acceleration
can be maintained for a very long time; this is particularly
sensible in terms of strategic mobility: a Sharlin can travel
through the hyperspace at very high speeds, cutting down the
operational times.
The weapon system is maybe the most relevant asset of the
Sharlin/Shargoti family: the Minbari main weapons are particle
cannons that fire continuous beams of antimatter neutralized
particles, with an enormous amperage and an unmatched power
output: such a scheme is essential to fight effectively against
the Shadow vessels, that must be subject to a continuous powerful
attack to ovrwhelm their energy dissipative armour, but is
devastating against all the targets, due to the sheer power and
the long range.
The Main antiship weapons are a spinally installed beam cannon
(Bow beam) with a power output of 7200 Terawatts (more than 10000
TW for the Shargoti) and six 3500 Terawatts beam cannons, two of
them placed inside the hull in the bow area, and the other four
placed in external pods, two forward facing on the sides of the
ventral fins, and two rear facing on the sides of the rear
gravimetric fins. These weapons are usully fired in short bursts
to avoid overheating, but the main bow beam is capable to sustain
a full power continuous fire more than 50" long, even if in
this case it requires a cooling down time of more than an half
minute.***
On the leading edges of the ventral fins are placed four fusion
discharge cannons, a short range plasma discharge weapon of
impressive destructive power, while on the masts visible on the
bow, on the secondary cannons pods and on the two upper corners
of the stern plate of the hull are placed a total of 18 steerable
"slicer beams", even in this case beam projectors but
with a steering system that allows the shifting of the beam on a
wide firearc (about 180°) - these weapons are conceived as
polyvalent systems, as point defence against the fighters and as
secondary antiship weapons - the power output is about 400-500
terawatts, well enough to inflict heavy damages even to an
averagely armoured warship.
In the root of the dorsal fin, forward facing, is installed an
heavy antimatter projector, a discharge weapons based upon
gravimetric technology (the conceptual ancestor of the quantum
discharge cannon), that at short range allows to fire a beam of
impressive power output (around 12000 Terawatts) - Due to the
large diameter (25-30 meters) and relatively scarce coherence of
the beam, this weapon has a relatively low penetrating power
respect to the main bow beam, but is a perfect solution to
overwhelm energy dissipative defences, like the one used by the
Shadows. The high power output makes of it a very effective
"demolition tool", but usually the Minbari crews prefer
to rely on the accuarcy and power of their main antiship beam
weapons.
It is available even a "Electro Magnetic Pulse
Projector", a weapon that is capable to fire an high power
Electromagnetic pulse capable to incapacitate the electronic and
electric sytems of a small sized craft up to some kilometers of
distance. As all the medium and large Minbari warships, the
Sharlin has embarked a gravimetric "tractor beam"
system, an array of small, directional gravimetric field
projectors that can be used in docking manoeuvres, to tow another
ship, or to "hook" it - range and low reaction time,
and even the limitated power level of this system precludes its
use as a weapon or a defence system.
The Point defence of the Sharlin, beyond the "steerable
slicers", relies heavily on its complement of fifteen Nial
fighters, whose effectiveness is beyond every doubt.
In the last two years, the whole fleet of Sharlins and Shargoti
is undergoing a retrofit program to equip all of them with an
interceptor grid, based upon 7 high rate of fire ion bolters
developed by the Minbari with the technical assistance of Earth
Alliance, that has given the basic technolgy, the technical
specifications and the design of the high torque, high precision
servomotors and of the special closed loop tracking and control
system needed to ensure the performance of the interceptors. The
"Anla'sa" (sentinel) Interceptors-CIWS ensure now to
the Minbari cruisers the same high level of defence against the
fire of bolt weapons that is typical of the EA warships, and
enhances the performances of the antifighter point defence. As
known, the sharing of the Interceptor technology is one of the
most significant contributions of the Earth Alliance to the whole
ISA, and one of the operational benefits of the agreements in the
ISA and the participants to the Treaty of the Four Stars.
The Sharlin and the Shargoti are universally considered the
"reference ship" for the younger races: Highly
advanced, long ranged, durable, fast, with an absolutely
devastating firepower and an awesome stealth system, they are
really superior weapons, and represent the true power of the
Minbari military, and, in fact, almost the best of the Inter
Stellar Alliance. The best testament of the real power of the
Sharlins is the simple fact that, among almost all the peoples of
the ISA, the most prized aknowledgement of the power and
excellence of a ship design is "... could go even
against a Sharlin".
THE SHARLIN IN COMBAT
|
* Note 1 - All the Human
ships, and almost all the known ships but the Minbari, have a
power-propulsion plant based on fusion reactors. The power output
of the reactors is not totally available for the onboard users
(weapons, jump engines and so on) for technical reasons: the
power generators are always magnetoplasmadynamics systems,
usually integrated in the engines. Even The fusion reactors are
integrated in the engines, and they feed directly the propulsion
system, if this is a Newtonian engine, so in first the whole
power output, in form of an overheated plasma flow, is channelled
in the engines and accelerated through them thanks to a magnetuic
nozzle. Beyond the primary nozzle is usually placed a
magnetoplasmadynamics generator, directly fed by the engine flow,
that taps part of the power of the flow to convert it in electric
enrgy, available for the users. This is the scheme used by the
Earth Allaince designs from the Nova to all the actual ships, by
the Centauri, and by the Narns in the G'quan and Bin'tak classes
and newer. Even if appearently complex, in fact the system is
simple, ruggedized and efficient. Usually, of the whole power
produced by the fusion reactor/engine complex, a percentage
between 10% and 20% is available for the electric power
production, this percentage being of about the 35% for the more
advanced gravimetric enhanced designs of the Centauri and of the
Earth Alliance. An Omega Epsilon has a power output of about
110000 Terawatts, but the power available for the users in
electric form (so to feed weapons and other systems) is about
36000 terawatts - these numbers are 310000 TW and 135000 TW
respectively for the Warlock; a Sharlin has the whole flow of
350000 or 360000 TW available for propulsion, or weapon feeding,
or jump engine recharge. This concept is applied even by the
Vree, and even in this case the firepower of their ships is
disproportionately high respect to mass and dimensions.
**
Note 2 - A
spinally installed weapon solidal with the hull, that requires to
aim the whole ship against a target to hit it, is a technical
choice that is commonly criticized; in fact, the disadvantages of
this type of installation are easy to see, essentially, a
relatively long reaction time and problems to fight against
multiple, side attacking foes at the short distances. The many
advantages, instead, are less easy to see: first of all is
possible to install a spinal weapon significantly longer, larger
and more powerful than a turret mounted cannon: classic samples
are the G.O.D. cannons, the spinal lasers, the Bow beams of the
Minbari cruisers; perhaps, the weapon is even more protected:
instead of being an external evident and visible target, it is
placed well inside the hull, only the gunports are exposed. Even
the eventual ancillary systems, coolant jackets, feeding systems,
energy accumulators, are much more protected. must be added that,
at least in the Human and Hyach designs, the spinally installed
weapons have shown to be more accurate than the turreted ones
(and the human weapons are maybe the most accurate in use). The
spinal installation, overall, is a good solution for long range,
powerful weapons: the distance means that the relative angular
speed of an even fast moving target is small enough to allow an
effective tracking even with slow manoeuvres, so if the power
grid of a ship can support a bulky, powerful, long range weapon,
the spinal installation is quite a good solution. As a note, the
Vree Xill light cruiser has its main weapon, a powerful array of
rapid fire antimatter bolt projectors, that is not only in a
fixed installation, but fires at 90° degrees respect to the main
plane of the ship (the Xill is a Flying saucer) - Due to the
extremely high acceleration and the awesome nimbleness of the
design, even at short ranges this unusual installation has shown
to be the most potent antifighter weapon known, devastating even
against the swarms of Shadow and Vorlon fighters, and the combat
performances of the Xill are excellent regardless the
"spinal" mount of its Antimatter Shredders. Must be
furterly remarked that, for the few that is known, at least two
Ancient races, the Torvalus and the Kirishiacs, use spinally
installed main weapons (on their extremely nimble and
manoeuverable ships, must be added), while Vorlons and Shadows
use spinal/internal main weapons installations, but with
steerable beams.
*** Note
3 - The Minbari ships, due to their gravimetric
drive and the highly efficient reactors, don't need to carry
large amounts of fuel, and so, paradoxally, this is a theoretical
limit in the full exploitation of the firepower: almost all the
beam weapons used by the Younger races, while intrinsecally very
efficient, need a certain cooling: given the fact that a warship
cannot use large radiating panels, the only solution is to use
the propellant tanks as heath sinks: the propellant is circulated
in the systems of the weapons, and sent back into the fuel tanks.
The large amount of mass stored, and the chriogenic temperatures
of the propellants used ensure the satisfaction of the cooling
needs: an Omega or a Warlock, with a residual 50% of the
propellant, can easily sustain more than two hours of continuous
use of the weapons before manifestating cooling problems, and
this is well beyond the average length of a fighting, that
usually, even in large battles, implies a series of engagements
of less than a minute each one, while the antifighter and point
defence systems, that usually fire for longer periods, have a
power output and cooling needs well below the main antiship
weapons. The Sharlin, with its small chriogenic fluids reserve
and the enormous power output of the weapon, theoretically needs
a "waste heath management" in a fight. In fact, due to
the overall superiority and the sheer power and devastating
effect of the Minbari weapons, a series of short discharges is
usually well enough to defeat almost all the average opponents,
and the "cooling question" never was a limitating
factor.
