The U.S. Department of State (DoS) ordered three upgraded S-61 utility helicopters, Sikorsky said Wednesday, bringing the total number of aircraft purchased by DoS to 29.
The three aircraft will transport diplomatic personnel in Iraq and Afghanistan. DoS entered into a five-year indefinite quantity agreement with the option to purchase up to 110 upgraded S-61 aircraft, according to Sikorsky.
“The S-61 helicopter is known as an industry workhorse and for decades has reliably performed missions for U.S. and foreign allied militaries,” said John Johnson, S-61 programs director.
The upgraded S-61 helicopters will undergo a full structural refurbishment with all major dynamic components zero-timed and key upgrades provided, including new composite main rotor blades (CMRB) and a survivability suite. The customer can select additional options such as a state-of-the-art glass cockpit and crashworthy primary and auxiliary fuel systems.
