A Sikorsky-Boeing team is expected to submit a proposal for the US Army's Future Vertical Lift initiative that may include counter-rotating co-axial main rotors and a pusher propeller, as in this concept from the team. Similar technologies could be included in a future US Navy MH-XX helicopter.
The Sikorsky H-60 Seahawk helicopter and Northrop Grumman C-2 Greyhound carrier-on-board delivery (COD) plane are longtime stalwarts of US Navy operations. The 35 Greyhounds constantly shuttle passengers and cargo to and from the fleet’s aircraft carriers, while some 460 H-60s of various models carry out a wide range of missions.
Both aircraft types will become due for replacement, and the way ahead for each has yet to be determined.
The newest C-2A dates from 1990, and the service is planning to award a replacement contract in 2016. Among the contenders are an updated version of the C-2A from Northrop, and a COD version of the Bell-Boeing MV-22 Osprey tilt-rotor aircraft.
