Retired in 2009 and replaced by the Air Force CV-22 version of the [[V-22 Osprey]], helicopters of the '''MH-53 PAVE LOW''' series are extensive modifications of the [[CH-53 Sea Stallion]] used as a heavy transport helicopter by the [[United States Marine Corps]] and the [[HH-53]] search and rescue helicopter. PAVE LOWs, in the MH-53J or M versions, can fly long-range, very low level, special operations missions in night or day, and in adverse weather, as single aircraft or in formations.

When earlier aircraft, such as the HH-53 or MH-53E were upgraded to version M, the major enhancement was the Interactive Defensive Avionics System/Multi-Mission Advanced Tactical Terminal (IDAS/MATT). This system greatly enhances present defensive capabilities of the Pave Low. It provides instant access to the total battlefield situation, using 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. Additional communications gear, including the [[ARC-210|AN/ARC-210]] [[SINCGARS]]-compliant and [[ARC-187|AN/ARC-187]] [[HAVE QUICK II]] compliant radios, has been added.

Retired in 2009 and replaced by the Air Force CV-22 version of the V-22 Osprey, helicopters of the MH-53 PAVE LOW series are extensive modifications of the CH-53 Sea Stallion used as a heavy transport helicopter by the United States Marine Corps and the HH-53 search and rescue helicopter.

Sensors and avionics

The basic suite includes terrain-following/terrain-avoidance radar, forward-looking infrared (FLIR) viewing, inertial navigation coupled with GPS, and a moving map display. Flight crew can wear night vision goggles.

When earlier aircraft, such as the HH-53 or MH-53E were upgraded to version M, the major enhancement was the Interactive Defensive Avionics System/Multi-Mission Advanced Tactical Terminal (IDAS/MATT). This system greatly enhances present defensive capabilities of the Pave Low. It provides instant access to the total battlefield situation, using 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. Additional communications gear, including the ARC-210|AN/ARC-210 SINCGARS-compliant and ARC-187|AN/ARC-187 HAVE QUICK II compliant radios, has been added.

In the M model, the defensive electronics build on those of the J model. There are now active electronic (e.g., jamming) and infrared defensives. To improve situational awareness, all the threat and countermeasure information is on a single display. The software will give immediate recommendations for avoiding or countering the threat.[1] The infrared countermeasures was not limited to flares, but directed energy from the ALQ-157|AN/ALQ-157 system.[2]

Cued by the AN/AAR-57 Common Missile Warning system and an AN/ALR-69|ALR-69A(V) direction-finding radar warning receiver, the PAVE LOW began with an AN/ALE-37, upgraded to an aN-|AN/ALE-47 Countermeasures Dispenser System (CMDS). The ALE-47 is a "smart" dispenser that can integrate with defensive avionics such as radar warning receivers, radar reflector (i.e., chaff (electronic warfare)|chaff) dispensers, radar jammers, as well as helping the pilot with situational awareness of the threat.
