The U.S.S. Enterprise, badly damaged after its encounter with Khan Noonien Singh, returned home to Earth for refit and repairs. Upon arrival, it was announced by Fleet Admiral Morrow that the ship would be decommissioned. Learning from Spock’s father, Sarek, that there may be a chance to revive his fallen son, Admiral Kirk broke Starfleet regulations by stealing the Enterprise from Spacedock and took it to the Genesis Planet to retrieve his comrade’s regenerated body. There, Kirk destroyed his ship to prevent it from falling into the hands of rogue Klingons and to save his crew.
Following a tense battle with Khan Noonien Singh at the Mutara Nebula, the damage that the Enterprise sustained had not spared its bridge. Explosions left charred residue on surfaces around the bridge, notably across the starboard-side turbolift alcove. After the ship sustained even further damage at the hands of a Klingon attack orbiting the Genesis Planet, most ship systems shorted out, leaving the bridge dark with its dim emergency lighting and most of its consoles shorted out.

For the film’s climactic scene featuring the self-destruction of the U.S.S. Enterprise, supervising model maker Steve Gawley and his crew actually constructed a complete model of the ship, one-third smaller than the original filming miniature, for full shots of the partially destroyed ship.

Being a direct continuation of the previous movie, the bridge was consciously left as close as possible to its last appearance. The Roddenberry Archive has chosen to depict the bridge as it was during its final moments, with dimmer lighting and inactive consoles.
