The MJU-51/B was developed by the USAF ASTE program and is designed to defend modern higher signature fighters and transports against the latest generation MANPAD and air-to-air missile threats world wide. The MJU-51/B utilizes Special Material, Alloy Surfaces’ proprietary patented technology, to emit IR energy in the same band as an aircraft. The MJU-51/B is manufactured in a 2”x1”x8” (MJU-7) form factor and can be employed using the ALE-4X series or any Countermeasures Dispensing System capable of employing 2”x1”x8” flares. The MJU-51/B is virtually unobservable to the naked eye in both daylight and night time conditions. It contains no pyrotechnics other than a BBU-35B squib required to expel the SMD from the flare casing. Once expelled the SMD reacts with oxygen to rapidly oxidize and generate an IR signature. However, the temperature is less than half the temperature of conventional MTV and SMD is extremely safe to handle.
