Onece 4 was a BFF-1 bulk freighter that was part of Onece group. Following the Battle of Hoth, it was shipping foodstuffs through the Javin sector, and went through customs at Outpost D-34. The freighter was inspected by Maarek Stele and after confirming its cargo to be legal it was allowed to leave. However, Onece 3 was actually smuggling Rebels and was disabled by Imperial forces and was captured, despite Rebel intervention. Onece 4, meanwhile, entered hyperspace bound for parts unknown.
