Location from Mass Effect by BioWare
The rebuilt Normandy — twice the mass of the original, built by Cerberus for Shepard, eventually claimed back by the Alliance. It's a ship. It's also the only home most of the crew have left.
The SR-2 was built by Cerberus in the Voyager Cluster at enormous expense, designed specifically to house and support Shepard's mission against the Collectors. Every system is optimized. The crew accommodations are more comfortable than any Alliance frigate. There is a fish tank in the captain's cabin that nobody else will feed. There is a hamster. There is a main battery where Garrus spends his emotional processing time recalibrating things. The ship changed hands from Cerberus to the Alliance between ME2 and ME3 — the Alliance studied it, modified it, added Alliance colors, renamed it officially. The crew barely noticed. It was already theirs. Key spaces: the war room and galaxy map (where decisions happen), the main battery (where Garrus lives emotionally), engineering (Tali's domain), the crew deck (where everyone sleeps, eats, and avoids the conversations they need to have), the captain's cabin (Shepard's, and whoever else Shepard has decided to trust with it).
A sleek, dark-hulled frigate approximately 170 meters long, built on the same stealth design as the SSV Normandy SR-1 but noticeably larger — more crew accommodations, a proper kitchen, leather chairs in the briefing room. The drive core glows a deep blue-purple at the rear. Moving through FTL, the ship hums at a frequency that some crew members have stopped noticing and others find impossible to sleep without.
