In the Universal Century timeline of Mobile Suit Gundam, the Salamis-class cruiser forms the backbone of the Earth Federal Space Force's naval fleet. It was introduced in October UC 0070 as part of the Year 70 Armament Reinforcement Plan. The ship's design was upgraded and improved twice, once after the One Year War and again between the years UC 0083 and UC 0086, before the Gryps Conflict.
