DuPont Aerospace DP-2

DP-2
Role	VSTOL transport
National origin	United States of America
Manufacturer	DuPont Aerospace

The DuPont Aerospace DP-2 is a fixed-wing VSTOL transport aircraft that is designed to take off and land like a helicopter and fly like an airplane. The DP-2 is designed to travel at high subsonic speeds with a greater range than its rotary-wing equivalent, and to allow troops to rappel from the aft cargo ramp. The development of the 53% scale DP-1 aircraft was originally funded as a manned vehicle. During the construction of the test aircraft, ONR program management changed the requirements, and mandated that the vehicle be tested as a UAV. This change added significant cost and time to the project, but in October 2007, the DP-1 autonomous prototype achieved sustained, controlled tethered hovers of 45 seconds at the Gillespie Field test site. The requirement for military helicopters is a 30 second hover.

On June 13 2007, the U.S. House Committee on Science and Technology held a hearing about the fate of the DP-2. [1] In August 2007, funding was finally cut, after a total of $63 million dollars spent over two decades. The general consensus was that this project was just a pork barrel for the local congressman.
