What is V-22 Osprey? The Boeing V-22 Osprey is a multi-mission military tilt rotoraircraft. It is takes-off and lands vertically like a helicopter, while itscruise speed is similar to propelled aircraft. The Osprey is seen as a replacement for the helicopter with theMarine Corps. The Osprey is powered by two Rolls-Royce AE Liberty turboshaft engines.
Emergence of V-22 Osprey The Bell Boeing V-22 made its first flight in 1989. It has a crew of two and can accommodate 24 troops. The US Marine Corps first took the initiative of such aircraft. The V-22 Osprey can operate from ships as well as small airfields.

TECHNICAL BUDGETThe V-22s development budget was first planned for $2.5 billion in 1986, then increased to a projected $30 billion in 1988. As of 2008, $27 billion had been spent on the Osprey program and another $27.2 billion will be required to complete planned production numbers by the end of the program.
APPLICATIONSIts primary task is to conduct long-range special missions and combat rescue.This aircraft is intended foe search and rescue missions and for delivering and extracting special forces troops.
ADVANTAGESThe Osprey is the worlds first production tilt rotor aircraft, with one three-bladed prop rotor, turboprop engine, and transmission nacelle mounted on each wingtip.For takeoff and landing, it typically operates as a helicopter with the nacelles vertical and rotors horizontal.The nacelles rotate forward 90° in as little as 12 seconds for horizontal flight, converting the V-22 to a more fuel- efficient, higher-speed turboprop airplane.
DISADVANTAGESThe V-22s production costs are considerably greater than for helicopters with equivalent capability, which has a greater payload and an ability to carry heavy equipment the V-22 cannot... an Osprey unit would cost around $60 million to produce.Between 2008 and 2011, the estimated lifetime cost for maintaining the V-22 fleet grew by 61 percent, mostly from increased maintenance and support costs.
FUTURE SCOPE/DEVELOPMENTSThe US marine corps are trying to make v-22 to take off from sea as well as float in it by replacing it’s landing gear.
