HOUSTON, Feb. 21 /PRNewswire/ — Sikorsky Aerospace Services announced today at Heli-Expo that the U.S. State Department has entered into an IDIQ (indefinite delivery-indefinite quantity) agreement to purchase up to 110 modernized S-61(TM) aircraft for passenger and cargo transport missions in support of its worldwide operations. Delivery of the first four modernized S-61(TM) aircraft will support missions for the U.S. Embassy in Afghanistan. Sikorsky Aerospace Services (SAS) is the aftermarket division of Sikorsky Aircraft Corp., a subsidiary of United Technologies Corp.
The S-61 helicopters are being delivered as part of the Sikorsky S-61T(TM) Program – a comprehensive modernization program to upgrade existing S-61/H-3 aircraft to increase performance in high/hot operating conditions. The S-61 helicopter is known as the workhorse of the industry and, for more than 50 years, has reliably and safely performed missions in U.S. and foreign allied militaries. The five-year purchase agreement for the S-61T helicopters will add to the U.S. State Department’s worldwide fleet.
“With its rugged endurance, spaciousness and lift capabilities, the Sikorsky S-61 helicopter continues to be one of the most dependable aircraft in the aerospace industry. Its outstanding and durable performance history has given impetus to the S-61T Modernization Program, which builds upon that proud legacy,” said David Adler, president of Sikorsky Aerospace Services.
Sikorsky and Pennsylvania-based Carson Helicopters Inc. have launched an exclusive joint upgrade program. The S-61T Modernization Program incorporates key upgrades that include composite main rotor blades, a state-of-the-art glass cockpit and modular wiring harness – all of which dramatically improve aircraft supportability. The S-61T helicopter also has been equipped with 1,200 pounds of added lift capability and enhanced speed capacity. Additional features have been incorporated to reduce pilot fatigue and reduced maintenance requirements for increased safety.
Providing an alternative to the Pentagon’s current purchase and use of Russian helicopters, Sikorsky’s American-made modernized S-61 aircraft is mission-ready now for deployment to Afghanistan and the surrounding regions.
