The Sikorsky Firefly is an all-electric helicopter built for research purposes by Sikorsky Aircraft. It has been called the world's "first all-electric helicopter".[1] The Firefly is a modified Sikorsky S-300C helicopter with its engine replaced by an electric motor and two lithium-ion battery packs. The helicopter would hold only the pilot and no passengers. Sikorsky reported an operating time of 12 to 15 minutes and a top speed of 80 kn (150 km/h; 92 mph).[2]
It was expected that the helicopter would make its first flight in late 2010 or early 2011.[1] For undisclosed reasons, the helicopter was never flown and the project is now defunct.[2]
