Sikorsky MH-53M ‘Pave Low IV’ Helicopter
The Sikorsky MH-53 is a variant of the USAF's HH-53 'Super Jolly Green Giant' air rescue helicopter, which was developed in turn from the US Navy's CH-53 'Sea Stallion' heavy lift helicopter. The MH-53 has been optimized for long-range infiltration, exfiltration and resupply of special operations forces in darkness or marginal weather flying conditions. The USAF began using early models of this helicopter for special operations missions in the late 1960s, and later versions continued to receive multiple improvements and upgrades thereafter.
In 1979-80, the Air Force modified nine MH-53Hs and 32 HH-53s to provide special operations units with the latest in avionics and sensor technologies under a program called Pave Low III. Those modifications included forward-looking infrared sensors, an inertial global positioning system, Doppler radar-navigation systems, terrain-following and terrain-avoidance radar, and integrated avionics to enable precise navigation to and from target areas. The USAF designated these modified helicopters as MH-53Js. In the late 1900s, 25 MH-53Js were fitted with new defensive avionics and other upgrades; these Pave Low IV aircraft became MH-53Ms.
