Sikorsky Aircraft and parent Lockheed Martin have assigned the S-100 designation to a newfangled helicopter the manufacturer sees as a platform for the U.S. military with similar potential to its Black Hawk utility helicopter and variant models.
Stratford-based Sikorsky and partner Boeing had previously referenced the prototype helicopter the companies are developing as the SB>1 Defiant, with the design borrowing the concept of dual, counter-rotating main rotors from Sikorsky’s experimental X2 that set in 2010 an unofficial speed record for rotor aircraft.
As first reported by HeliHub, Sikorsky registered the S-100 with the Federal Aviation Administration, confirming to the trade publication Vertical that is the new name for the SB>1 Defiant. Sikorsky is aiming to begin flight tests this year for the helicopter.
The last “S” series designation for Sikorsky was the S-97 Raider, a smaller version of the S-100 with the latter aircraft sized to carry a dozen troops.
