The Breha functioned as a diplomatic starship utilized by the Alliance to Restore the Republic. The ship's architecture bore a striking similarity to the J-type 327 Nubian starship. After the destruction of the Death Star, Leia Organa and Luke Skywalker embarked on a clandestine mission to Tibrin aboard the Breha, masquerading as diplomats representing House Berenko of Naboo with the intention of arranging a trade agreement. During this mission, Imperial forces caused the Breha to crash into the ocean.
