Sikorsky CH-53E Super Stallion - largest and heaviest helicopter in us armed forces

introductionThe Sikorsky CH-53E Super Stallion is the largest and heaviest helicopter in the United States military. As the Sikorsky S-80 it was developed from the CH-53 Sea Stallion, mainly by adding a third engine, adding a seventh blade to the main rotor and canting the tail rotor 20 degrees. It was built by Sikorsky Aircraft for the United States Marine Corps. The less common MH-53E Sea Dragon fills the United States Navy's need for long range mine sweeping or Airborne Mine Countermeasures (AMCM) missions, and perform heavy-lift duties for the Navy.

designThe fuselage is watertight and of light alloy, steel and titanium construction. The cockpit includes glass fibre and epoxy materials.The seven-bladed main rotor is fitted with a Sikorsky blade inspection system. The main rotor blades are of Nomex honeycomb construction with a titanium spar and a composite glass fibre and epoxy skin. The rotor head is primarily titanium and steel.

cockpitThe CH-53E accommodates three crew. The helicopter is equipped with a Hamilton Sundstrand automatic flight control system (AFCS), with two digital flight control computers, a four-axis auto-pilot, an attitude and heading reference system (AHRS), a Rockwell Collins GPS 3A global positioning system and a Northrop Grumman (Teledyne Ryan) AN/APN-217 Doppler radar. The AHRS has been replaced with a new system from BAE Systems.

engineThe CH-53E helicopters are powered by three General Electric turbofan engines, type T64-GE-416 rated at 3,266kW. The engine cowlings and transmission fairings are of Kevlar construction.Self-sealing bladder fuel tanks, each of 1,192l capacity, are installed in the forward sections of the sponsons. An internal two-cell fuel tank provides 1,465l of fuel. Drop tanks, with total capacity 4,921l, can also be installed externally to each sponson.

Electric warfareThe Super Stallion is equipped with an ATK AN/AAR-47 missile warning system and chaff and flare dispensers.An initial six CH-53 helicopters of the German Armed Forces are fitted with the EADS AN/AAR-60 MILDS missile warning system, also fitted on the NH90 and Tiger helicopters.In June 2007, Northrop Grumman was awarded a contract to equip the USMC CH-53E helicopters with the directional infrared countermeasures system (DIRCM).
