>Two primary missions—airborne mine countermeasures (AMCM) and vertical on-board delivery (VOD)
>AMCM mission includes: mine sweeping, mine neutralization, mine hunting, floating mine destruction, and channel marking.
>VOD mission includes transporting cargo, supplies, and personnel to/from ships and shore facilities.
>Program Summary:
>
>U.S. Navy took delivery of the last of 48 MH-53Es in September 1994; 12 were procured for the Naval Reserve.
>Three fleet squadrons operate the MH-53E: HM-14 and HM-15 (combined active/reserve AMCM squadrons) and HC-4 (NAS Sigonella, Italy-based VOD squadron).
>Training conducted in HMT-302.
>A validation/verification contract was awarded in FY95 for the Global Positioning System/cockpit upgrade integration effort. This program, known as the MH-53E Navigation/Communication System, will meet GPS navigation requirements and will correct a mission navigation system deficiency.
>Three of four fleet retrofit contracts have been awarded for the T64-GE-419 engine upgrade program. Retrofit of the 419 engines are scheduled to commence in FY97. The 419 engine can produce 5,000 shaft horsepower and will correct a deficiency concerning one-engine-inoperative performance during AMCM operations.
>Additional H-53 generic modification programs include: the AN/ARC-210, No. 2 engine thermal detector, NVG compatible exterior lighting, tail rotor drive shaft disconnect coupling monitor, integrated mechanical diagnostic system, and a service life extension program.
