MH-53E Sea Dragon Helicopter

 
Description
The MH-53E is used primarily for Airborne Mine Countermeasures (AMCM), with secondary missions of vertical shipboard delivery and assault support. It incorporates Global Positioning System (GPS), Doppler radar, and an Approach/Hover/Tow Coupler. Communications include Ultra High Frequency (UHF)/ Very High Frequency (VHF)/ High Frequency (HF) radios, secure communications capability, and Identified Friend or Foe (IFF).
 
Features
The MH-53 can operate from carriers and other warships and is capable of towing a variety of mine hunting/sweeping countermeasures systems, including the Mk 105 magnetic minesweeping sled, the AQS-14A side-scan sonar, and the Mk 103 mechanical minesweeping system. When performing the assault support mission, the MH-53E can be fitted with the GAU-21 .50-cal. machine gun ramp-mounted weapon system.
 
Background
The MH-53E was derived from the CH-53E Super Stallion and is heavier and has a greater fuel capacity than its ancestor. Currently the program is executing an in-service sustainment strategy to ensure continued AMCM and heavy-lift support to the sea base until the transition to the Littoral Combat Ship mine countermeasures mission package is complete. The sustainment strategy addresses fatigue, obsolescence, readiness, and safety issues. A fatigue life extension program has been completed, which extended the aircraft service life to 10,000 hours, enabling the Navy to maintain a dedicated AMCM capability through the 2025 timeframe.
