Designation:

Excalibur-class Submersible Assault Ship (SLV)

Class History:

Ship's complement:

Note: The given numbers are approximations; the exact number varied somewhat due to operational realities and different ships.

Dimensions:

Propulsion systems:

Main power system: 2 Rolls-Royce FWR-12 or fusion reactors with a rated power of 277 MW each.
Propulsion systems (8): Westinghouse CE-6 MHD engines mounted in two sets of three at the lower stern of the ship, with the exhausts surrounded by a heavy shroud for impact protection and infra-red signature reduction.
The total effective propulsive power is 1.6 million SHP.

Endurance and mobility limits:

The dry stores endurance is 3 months maximum; after that, the Excalibur-class need to restock, most commonly from an underway replenishment ship. Potable water and oxygen can be obtained from the surrounding ocean.
The effective life of the fusion reactors is 30 years.
The maximum speed is 38 knots surfaced and 22 knots submerged. The maximum diving depth is 560 meters operationally, and 1000 meters in an emergency.
The mecha consumables supplies (mainly missiles) are limited; the Excalibur is unable to sustain continuous combat operations for much more than 10 days.
The missile magazines for the ship's own launchers are typically empty after 3 major assaults.
The magazine for the ship's torpedo tubes can store 300 large weapons such as heavyweight torpedoes or cruise missiles.

Weapon systems:

Bofors PL-7 point defense turrets (8): These standard RDF weapons can fire 130 MJ of particle energy four times per second at a range of up to 10 km.
Raytheon MLB-18 missile launchers (6) : A 'pepperbox' missile launcher with 10 missiles ready to fire and another 30 missiles in the magazines for each launcher. The system fires Avatar and Savior surface to surface missiles. The launchers line the deck edge.
Bofors QRB-18 missile bins (6) : A flush mounted bin for quick-reaction anti-mecha missiles. Each bin contains 6 high-explosive, short range (maximum 3.2 km) Mach 3.0 combined IIR/passive laser homing SA-20 Shortbow missiles. There are fifteen reloads for each bin.
Mk82 760mm torpedo tubes (6) : Conventional albeit large torpedo tubes. These can fire a large variety of weapons. Weapons with a diameter of less than 760mm can be fired by using liners in the tubes. The weapons used are most often Honeywell Mk96 Shark VADCAP 533mm multi-purpose torpedoes and cruise missiles.
