Bravo One, a UT-60D transport/[gunship], provided service to the Alliance to Restore the Republic's Extraction Team Bravo during the time of the Galactic Civil War. In 0 BBY, under the leadership of General Davits Draven, Bravo Team undertook a successful operation to liberate Jyn Erso—a human female criminal who later became crucial to the theft of the Death Star blueprints—from an Imperial labor camp located on the planetary surface of Wobani.
Following a successful extraction from the planet, Bravo One experienced a small mechanical issue, preventing it from entering hyperspace. The team sought shelter within an asteroid field within the Wobani system, and K-2SO—an KX-series security droid who had previously served the Empire—sent a high-priority message to all accessible Rebel ships.
