Dixieland
From Gineipaedia, the Legend of Galactic Heroes wiki
The Dixieland was the flagship of the United Earth Government's Space Force's 4th Patrol Division in the early 26th century CE. It was commanded by captain Arnold F. Bach.
The Dixieland gained widespread prominence, or noteriety, when it was used in the 2527 Military Expenditure Hearings to demonstrate the decadence of the UEG's Space Force. (LOGH: 'To Earth')
