The aircraft is scheduled to be delivered to the U.S. State Department in the first quarter of this year, followed by a dozen other upgraded Sea Kings.
"The first flight of the S-61T represents a major milestone in the program," said Steven Rogers, Director S-61 Programs. "The modernized S-61T helicopter can be outfitted to meet a wide variety of requirements, and we believe it provides best-in-class-value for a midsize, multimission helicopter."
The S-61T has undergone full structural refurbishment and overhaul of all major components. Key upgrades include new composite main rotor blades, a survivability suite and state-of-the-art glass cockpit, as well as new electrical wiring throughout the aircraft.
The State Department has so far received 16 refurbished S-61 aircraft from Sikorsky, which is supplying 13 of T variant aircraft under a five-year indefinite-delivery/indefinite-quantity agreement for as many as 110 S-61 helicopters.
