The LWJ-251 deflector shield projector was the shield generator used aboard JA-347 starfighters and 1JD-1 droid starfighters. Like the rest of those fighters, it was developed by Eniam Nationalized Engineering. The LWJ-251 was powered by a JLJ-56 reactor.
JLJ stood for Lohjohinik Waklukkih Jahkohklukk, which was Driyoin for Energy Shield System.
