The JLJ-56 reactor was a highly efficient reactor core developed by Eniam Nationalized Engineering. The JLJ-56 was used in their JA-347 starfighters and 1JD-1 droid starfighters. It was similar to the older JLJ-51 reactor, but was larger and more powerful to support the new shield generator about the two starfighters. JLJ stood for Johiklukkialoh Lohjohinik Jahkohklukk, which was Driyoin for Advanced Power System.
