The 13th Autonomous Corps (第13独立部隊?) is a faction featured in the Mobile Suit Gundam television series and the Mobile Suit Gundam II: Soldiers of Sorrow and Mobile Suit Gundam III: Encounters in Space compilation films. During the One Year War, it was an independent subdivision of the Earth Federation Space Force's Tianem Fleet, to which the White Base was assigned prior to its return to space. The composition of the 13th Autonomous Corps changed over time, as the White Base sometimes travelled by itself, and on other occasions, was escorted by a handful of cruisers .
Bright and Mirai sat before a trio of Federation officials, led by Admiral Gopp. Admiral Gopp stated that the White Base corps would continue to operate as it had in the past. Continuing, he assigned them to the Tianem Fleet but said they wouldn't be given official notification until it commenced .
Later on, the other members of White Base crew would hear from Lieutenant Colonel Antonio Callas that their composition would remain the same, formally being made a part of the 13th Autonomous Corps of the Tianem Fleet. LtCol Callas proceeded to announce each of the crew's ranks and names while another officer handed out their assignments. Fraw Bow arrived late to receive her assignment as she had to deal with Katz, Letz and Kikka, all of them refusing to leave White Base, Childcare Officer Kolin decided to assist Fraw in talking to them. The casualties of the crew were all given two rank promotions with Ryu Jose posthumously assigned and promoted to LTJG. Amuro decided to speak up against LtCol Callas, believing mere promotions were not enough .
LTJG Sleggar Law was transferred to the 13th Autonomous Corps an hour before the White Base was scheduled to leave Earth .
