Remarks (Bemerkungen)
The development of the V-22 Osprey began in the 80s. First flight was on March 19, 1989 at Arlington (Texas). Six prototypes were built, all now retired. After near cancellation and total restructuring, the programme is now in an EMD phase lasting until 1999. Four new production representative prototypes, which are lighter and cheaper, have been built. The first EMD aircraft (no. 7) flew on February 5, 1997 and was ferried to Patuxent River (Maryland) in March, where the integrated test team is located. An operational evaluation is scheduled for January to June 1999. Deliveries of series aircraft are due to start in May 1999 for an IOC with the US Marine Corps in 2001. Production figures are subject to change, as the latest Quadrenniel Defense Review of the Pentagon mentions a cut to 360 MV-22s, while at the same time advocating acceleration of deliveries. Development of the CV-22 version was funded in December 1996 with a contract modification worth 490 million US-Dollars.
