The Sikorsky S-92 is an evolution of Sikorsky’s S-70 US Army Black Hawk and US Navy Seahawk helicopters. The Sikorsky S-92 was announced in March 1992, but an official program launch had to wait until the Paris Air Show in June 1995. First parts were built in 1996, starting with the main transmission housing. Assembly operations at Stratford began in 1997. Five prototypes are being built at Stratford for ground and flight tests to be conducted at the West Palm Beach Development Fight Center in Florida. The maiden flight December 23, 1998 consisted of eight takeoffs and landings and included hover, forward and sideward flight maneuvers. The first two helicopters are fitted with General Electric CT7-6D engines, while the others will get the CT7-8.  First delivery was on September 27, 2004 to Petroleum Helicopters Inc.
