Modern US Military Turbine Missile Fuel Specifications
RJ-4, RJ-5 and RJ-6 are fuels developed for ram-jet missiles. RJ-4 was for the Navy Sea Launched Cruise Missile. RJ-5 was selected for the Air Force Air Launched Cruise Missile program but replaced by RJ-6 due to low temp performance issues. JP-9 was also used by the Air Force for Air Launched Cruise Missiles but was replaced by JP-10.
