United Technologies
Description:
Sikorsky H-53 program was born to meet the requirements of the US Marine Corps (USMC) for a heavy-lift transport helicopter suitable for shipboard operations. Its primary mission is to transport supplies, troops and equipment in support of amphibious and shore operations. The program was launched in the early 1960s with the CH-53A Sea Stallion achieving initial operational capability (IOC) in November 1966.
CH-53D Sea Stallion is an improved variant of CH-53A. CH-53A/D models are powered by two General Electric T64 turboshaft engines and feature a six-bladed main rotor. CH-53D is powered by two T64-GE-413 engines rated at 3,935-shp each. In addition to A and D models for the USMC, Sikorsky also developed the HH-53B/C/H variant for the US Air Force and the RH-53D Airborne MineCountermeasures (AMCM) for the US Navy. US Air Force H-53 aircraft led to the MH-53J Pave Low III.
The CH-53E Super Stallion, also referred to by Sikorsky as the S-80, is an enlarged variant of CH-53D model. CH-53E is powered by three T64-GE-416 turboshaft engines and has a main rotor with seven blade instead of only six in previous models. These changes are meant to greatly improve CH-53E lifting capabilities. Between 1980 and 1999 Sikorsky delivered approximately 150 CH-53E helicopters to the Marine Corps. The US Navy also ordered the CH-53E for ship resupply.
MH-47E Sea Dragon is a variant of CH-53E Super Stallion. It is powered by three General Electric T64-GE-419 engines and is capable of towing a variety of mine-sweeping countermeasures systems. MH-47E primary role is Airborne MineCounterMeasures (AMCM) and its secondary roles are vertical shipboard delivery and assault support. Sea Dragon was developed as a replacement for aging US Navy's RH-53D AMCM helicopters. It results heavier and has greater fuel capacity than its ancestor.
The first Sea Dragon achieved Initial Operational Capability in 1983 in the US Navy. The MH-47E was exported to Japan which procured 11 aircraft under S-80M-1 designation. The US Navy and the USMC received more than 220 CH-53E and MH-53E helicopters from Sikorsky between 1980 and 1999.
