JA189 was a TIE fighter pilot who served the Galactic Empire during the Galactic Civil War. After the Battle of Hoth, JA189 and three other pilots were sent into the Hoth asteroid belt to chase down the Millennium Falcon. Imperial Lieutenant Commander Ciena Ree helped coordinate the four pilots from on board the Executor-class Star Dreadnought Executor, but even with her aid all four TIE/ln space superiority starfighters crashed within the belt while chasing the Falcon. JA189 was the second to crash.
