MH-53J/M PAVE LOW Fact Sheet 
The Mission
The Pave Low's mission is low-level, long-range, undetected penetration into denied areas, day or night, in adverse weather, for infiltration, exfiltration and resupply of special operations forces.
Features
The MH-53J Pave Low III heavy-lift helicopter is the largest, most powerful and technologically advanced helicopter in the Air Force inventory. The terrain-following and terrain-avoidance radar, forward-looking infrared sensor, inertial navigation system with global positioning system, along with a projected map display enable the crew to follow terrain contours and avoid obstacles, making low-level penetration possible.
The MH-53M Pave Low IV is a J-model that has been modified with the Interactive Defensive Avionics System/Multi-Mission Advanced Tactical Terminal or IDAS/MATT. The system enhances present defensive capabilities of the Pave Low. It provides instant access to the total battlefield situation, through near real-time Electronic Order of Battle updates. It also provides a new level of detection avoidance with near real-time threat broadcasts over-the-horizon, so crews can avoid and defeat threats, and replan en route if needed.
Under the Pave Low III program, the Air Force modified nine MH-53H's and 32 HH-53s for night and adverse weather operations. Modifications included forward-looking infrared, inertial global positioning system, Doppler navigation systems, terrain-following and terrain-avoidance radar, an on-board computer, and integrated avionics to enable precise navigation to and from target areas. The Air Force designated these modified versions as MH-53J's.
