General Dynamics VC-27 "Tunny" Heavy VTOL Cargo Plane
WARNING: DRAFT Material!
- Length: 58 meters
- Wingspan : 60.2 meters
- Height: 14.9 meters
- Dry Weight: 112.3 metric tons
Four+ seat long-range heavy military tactical VSTOL transport aircraft.
- Crew of 5: 2 Pilots, 2 Observers, Load Master
- Up to 120 Passengers with full combat gear
- 4 P&W F117PW-100 (PW2040) turbofan engines with two-dimensional vectored thrust nozzles providing 181 kN of thrust each.
- 4 secondary P&W F200 turbojet engines with vectored vanes for vertical take off and landings capable of providing 32.3 kN of thrust each. There is a large intake on the top of the fuselage with four vanes on the bottom-side under the canards. These engines provide vertical lift for the front of the aircraft during VTOL and STOL operations.

- Thomson DOS-2000f multi-band digital camera system, for medium range forward-looking traversable UV, infra-red imaging;
Tactical Electronic Warfare System (TEWS):
- Elettronica Radar Warning Receiver (RWR)
- OlDelft Infra-red Warning Receiver (IRWR)
- Westinghouse ALQ-200(V) active radar jammer
- Chaff dispenser
- Multiple HF, VHF, UHF and SatCom antennas.
Full nuclear and chemical protection as long as the cargo door are closed. Limited protection from hand fired solids and energy beams, shrapnel and other fragments.
The Tunny was developed to be able to haul heavy loads to rugged areas. As an improvement to the McDonnell-Douglas C-17, this aircraft provided VTOL capabilities to ensure that the aircraft could land anywhere. However, use of this capability limits the cargo capacity and range severely. Normally, the additional engines are used for STOL operations allowing the aircraft to haul a full load off of a 300m runway.
