S-76® Helicopter 

 

The legendary S-76® helicopter operates successfully in more than 40+ countries on five continents, fulfilling its many missions in varied environmental conditions found worldwide.

The proven S-76® helicopter continues to improve, responding to today's most critical market requirements with increased performance, quiet comfort and spacious cabin interiors, enhanced safety, dispatch reliability, operating cost efficiencies and superior mission versatility.
The S-76D helicopter is truly the next step in helicopter technology, setting a new standard of excellence that S-76® helicopter operators have come to expect. Power and performance are enhanced by all composite main rotor blades and optimized Pratt & Whitney Canada PW210S engines with dual FADEC controls. Its quiet tail rotor will allow for reduced external acoustic signature and gain acceptance with the communities where it operates. Pilots will appreciate the state-of-the-art integrated Thales cockpit, its increased range and its ability to launch into known icing conditions. With the increased measures for a quieter cabin, passengers will enjoy a heightened travel experience.

Introduced in 1977, the S-76 series has had a long legacy of supporting our customers with reliability and comfort. Originally built for the rigorous demands of the offshore oil market, its capabilities fit naturally into other market segments, such as executive transport, SAR, Airline and helicopter Emergency Medical Services.

Earlier versions of the S-76 helicopter include The S-76ATM and S-76A+TM helicopters (307 built), S-76BTM helicopter (103 built) and S-76CTM , S-76C+TM helicopters (191 built), and S-76C++TM helicopters (214 built). These machines continue to be productive assets for our customers and Sikorsky solidly supports them through our Sikorsky Aerospace Services division.
