BARD PAPER: SARA5000
Leviathan-Class Assault Transport
design by Lewis Roberts
From Path of Tears pg 38
"These ships will provide the Coalition with the capability to
move large numbers of combat troops from one world to another and
conduct opposed landings. Each of these ships will carry a light
brigade, and include launch facilities for a spearhead battalion
of drop troops. Although this capability is not intended for use
in combat, the Leviathan-Class will be streamlined to
allow landing on planetary surfaces.
Proponents of the coreward stategy see these ships as providing
new capabilites to pacify worlds far out in the AO, while
consolidating strategists expect that these ships will be used
closer to home."
POT lists a brigade as having three batallions of roughly 500
soldiers each. I assumed a light brigade was one with only two
battalions. The ship is also supposed to be able to drop a
spearhead battalion into combat. I figured that 400 soldiers and
100 dummy capsules dropped with most of their command and control
assests located on the ship sounded like a spearhead battalion.
The ship was designed with FFS with the help of Antti
Lahtinen's spreadsheet. An older
version was designed with SSDS
The Leviathan-Class Assualt Transports will be the
biggest ship in the Coalition Navy upon completion. The same team
of Naval architects that designed the rest of the Clippers
designed the Leviathan-Class. It shows this lineage, both
in its appearence and its internal arrangements. The ship looks
like a streamlined version of the Aurora and
Maggart-Classes Clippers, with the addition of small
stabelizing wings in common with theLancer and
Fussilier-Classes. (For a picture of the
Lancer/Fussilier-Class see their respective Battle
The inside of the ship also resembles the other Clippers. This
has its good points and its bad. The mechanical systems on each
of the clipper line tend to be versions of each other, and
reduces the amount of training maintence staffs need. The
staterooms are also identical allowing transfered sailors to
feel instantly at home. Unfortunatly some of the problems with
the other clippers have not been fixed, every stateroom still
has the same badly designed fresher made by Novastar Inc. It has
a habit of backing up and "regurgitating" its contents back over
the floor of the fresher. The Navy has tried to get Novastar to
fix the design but since Novastar's CEO August Delparo was just
arrested for treason, the company is in a state of confusion and
has been unable to come to any agreement over replacing the
designs. So when Delparo gets convicted, alot of Coalition
sailors will cheer his downfall.
During a hostile landing, 400 marines will use the drop capsules
to make a meteoric descent. They will be accompianed by 100 MK II
capsules in various loadouts, depending on the mission and the
commander's preferences. (For details on drop capsules see RCEG.)
At the same time the ship will be firing planetary assualt
missiles at enemy targets. As its laser turrets are equiped with
tunable lasers, they can also be turned on targets on the ground,
though they are intended at point defense weapons.
Once a beachhead has been achieved, the ship can launch its
Fury-Class Assualt Landers, which carry a further 196
marines. At the same time, any carried grav vehicles can be
launched. These can include Intrepid-Class Grav Tanks,
Pyrrhus-Class Support Sleds, and
Ferret/Mongoose-Class Attack Speeders. The remaining Marines
can be carried down by a second wave of the Furies or the
Leviathan itself can land. This is only done when the landing
zone is secure.
The Leviathan is designed to do more than simply transport
the Marines to their destination, once above the battle site it
can provide support to its Marine complement. It has 500
planetary assualt missiles (see RCEG for details) to soften up
ground targets. It also has numerous communcation facilities to
act as a command post while the battle is underway. It has an
additional computer which is for use by the Marine complement for
mission planning. It carries several surveilence satellites in a small
2-ton hanger. These satellites can be launched to provide real time
knowledge of the battlefield.
The Leviathan is normally expected to carry a Drop Infantry
brigade, but in case it carries an armored brigade, the Heplar
drive has been built oversize to compensate for the greater density
of armored vehicles. THe Leviathan can carry an extra 10,000 tons
without any loss of mobility.
It is not expected that the Leviathan-Class will opperate
alone. It does not have the firepower to take out opposing
starships. It will probably operate in concert with several
clippers or destroyers. After these ships have cleared away
enemy spacecraft they can be used as orbital artillery.
Fussilier-Class will not tend to be used in this role, as
their partical accelerators do not work as well in this role as
theLancer-Class's meson gun. Aurora-Class,
Maggart-Class, and Belladonna-Class Clippers can
also carry fighters which will provide air support to the troops.
