In the fictional Gundam universe, the SCV-70 (LMSD-71) White Base was a Pegasus-class mobile suit carrier deployed by the Earth Federation. Through the first part of One Year War, the White Base's registration name was unknown to the Zeon forces, so they referred to her by the codename 'Trojan Horse' no doubt because of her unusual shape. After the war, she was re-designated MSC-02 even though she had been destroyed at A Baoa Qu.
