Description
THE MJU-50/B is a Special Material Decoy (SMD) Pyrophoric Infrared (IR) Countermeasure developed and manufactured for the United States Air Force Advanced Strategic and Tactical Expendables (ASTE) program by Alloy Surfaces Co., Inc. Designed to counter advanced threats surface-to-air and air-to-air IR guided missiles, the MJU-50/B utilizes Alloy Surfaces proprietary patented technology to emit IR energy in the same band as the aircraft and is designed to protect lower signature fighters, transports and helicopters. Virtually unobservable to the naked eye in both daylight and night time conditions, the MJU-50/B can be carried in the ALE-4X series, and all other dispenser systems capable of employing 1”x1”x8” (M206 series) IR Countermeasures. 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.
