Designed by Yang Enterprises under a secret contract with the Terran Alliance, the Lagos-class Battlecruiser was originally designed to protect the Terran Alliance’s colonies once they were founded, but the prototype’s existence was was discovered and exposed by the media before it could be completed. As such, the Lagos-class became the first capital-class ship in the Navy’s arsenal, and at the same time became a cover story for the construction of the new attempt to covertly protect colonies – the Conqueror-class. Structurally, the Lagos and the Conqueror are identical, with identical weapons loadouts. This made it easier to hide the construction of the Conqueror-class ships, since the parts being shipped to the Yang Enterprises Neptune Astroconstruction Facility could be classified as being for Lagos-class vessels.  The primary difference between the Lagos and the Conqueror classes is that the Lagos class lacks the Korovin-Arakaki Active Optical Camouflage System (KAAOCS – “Kay-Ox”) and the Vantablack coating which give the Conqueror its remarkably low visual signature.

Weapons loadout comprises 12 torpedo tubes (4 fore, 4 aft, 2 port, 2 starboard), 60 missile tubes mounted in distributed batteries for broad coverage, 8 Turov-Barker Corporation Andromeda-type 128-megajoule railgun turrets, 40 Pandyne Integration 1-megawatt pulse laser systems divided equally between turret mounts and flush emplacements, one light gas gun battery comprising two Northtech-Microstellar 400mm methane combustion light gas guns, and one spinally-mounted Artemis-class bombardment laser.

Embarked auxiliary vehicles include two flight of fighters (7 per flight , ‘command standard’ of one wing of attack craft and one wing comprising 4 interceptors and 3 bombers) and one flight of swift assault craft (‘command standard’ of two Incursion-class assault craft, two Octopus-class close-in weapons system vessels, and one Striker-class marine assault craft).  Additional hangar space exists for one Ferry-class Swift Cargo Vessel, four general purpose transport shuttles, one vehicle of up to the size of a Hecate-class runabout, and a dedicated hangar bay designed for Hermes-class couriers – however the hangar space for these vehicles is not considered to be on combat alert and requires more time to prep a vehicle for launch.

Crew complement aboard a Lagos-class is one of the highest in the fleet, surpassed only by the Iwo Jima-class and the planned Antarctic-class Mobile Marine Bases.  Consequently, accommodations are military-standard: enlisted crew hot-bunk, junior officers have shared quarters, and command officers have private quarters. Traditional crew numbers comprise 7 command officers (ranked O-4 through O-6, O-7 if the vessel is the flagship of a battle group, though occasionally the leader of the embarked marine battalion is actually a W-5 warrant officer), 26 junior officers (O-2 through O-3 and W-3 through W-5), and 359 enlisted crew.

Construction of the Lagos-class was originally terminated with the Kano due to the high cost of building, operating, and maintaining the vessels.  Naval strategic planners saw no need to build more of them since there was no real threat for them to face.  In the wake of the attack on New Geneva construction was resumed, however retooling construction bays which had been refitted for other uses took time and Joint Fleet Command does not expect any new Lagos-class vessels to launch before Q2 2031.
