The Lethe-class mobile command base was the United Kingdom of Isselmere-Nieland's response to Questers' Hood-class and Praetonia's Iron Duke-class super-capitals. Strangely, the Lethe was comparable to neither of those vessels, being much more similar to Whittier's so-called Battle Island, a fortship, or an Orwellian floating fortress from 1984.

Armour
Type: Lethe-pattern (RANAC441)
Compartmentalisation: 272 transverse and 12 longitudinal bulkheads, supported by hardened crossbeams, triple-bottomed with a reinforced distributed keel, with alternating dry-wet layers. 72 NBC main citadels, 144 smaller NBC safe areas.
Shell: Shell of anechoic, corrosion-resistant, environmentally-safe, encrustation-repellant polymerised ceramic tiles (hull bottom to maximum safe draught level), high temperature-resistant polymerised ceramic tiles (above)
Decapping layer: 610 mm layered composite of case-hardened austenitic nickel-molybdenum-steel alloy, backed by 250 mm of reinforced water-resistant concrete followed by 210 mm layer of high hardness steel spall-liner followed by boron-carbon layer protected by titanium-infused polymerised ballistic ceramic for NBC protection, followed by wet layer. (1070 mm)
Frame: high-strength low-alloy structural steel (HSLASS) skeleton and bracers, former covered by a skin of 760 mm of face-hardened triple hardness steel at a twenty-two degree angle, backed by 508 mm of water-resistant concrete reinforced with depleted uranium rods braced by TAV spacers — dry layer — followed by 760 mm high hardness steel alloy plating, separated by 300 mm of KERI foam and HSLASS bracers, lined by a 210 mm face-hardened high hardness steel, ballistic polymerised ceramic anti-spall liner and NBC layer — wet layer. (2538 mm)
Inner frame: 210 mm face-hardened high hardness steel, ballistic polymerised ceramic anti-spall liner and NBC layer, followed by KERI foam and internal furnishings — dry layer (610 mm).
Torpedo bulkhead: At 26-degree angle, composition comparable to decapping layer.
Hull bottoms: 610 mm layered composite of face-hardened austenitic nickel-molybdenum-steel alloy plates supported and braced by HSLASS, filled with 250 mm KERI foam, followed by 406 mm layered composite of face-hardened triple hardness steel plate supported by HSLASS girders braced by HSLASS spacers with void space filled by KERI foam and NBC layer, with a 406 mm layered composite of face-hardened triple hardness steel covered by a ballistic polymerised ceramic anti-spall liner and NBC layer.
Decks: Covered in corrosion- and slip-resistant polymer coating over steel alloy plating. Deck armour of steel alloy, ballistic ceramic plates, titanium alloy bracing (with titanium alloy plating over key areas), KERI foam, steel alloy plating, steel alloy bracing, ballistic fabrics (spall protection), and tempered ballistic plastic plates. Main deck armour at 30-degree downward angle from horizontal, connecting the base of the superstructure with the hull.
Reactors: Protected by additional level of depleted uranium rods (armour) and heat exchangers and insulation to diffuse infra-red signature and noise.
Main missile batteries: protected by additional layer of ballistic ceramics and by high volume flooding mechanisms. Launch ports for heavy missile batteries protected by deck armour.
Gun batteries: Tertiary guns (155mm ETC) positioned outside first longitudinal bulkhead (secondary hulls), secondary guns (210mm RG) positioned between first and secondary longitudinal bulkheads (primary hulls), with additional titanium plating around the magazines and immersion systems to quell fires. Primary guns and magazines are "quadruple-hulled."
