Back in October, at the military blog DefenseTech, Kris Osborn reported that:

Bell Helicopter is beginning to manufacture parts for its new V-280 Valor tilt-rotor aircraft, a next-generation helicopter being developed as part of the Army’s Joint Multi-Role Technology Demonstrator, or JMR TD program.  The program is an Army-led joint program designed to replace the Army’s current fleet of helicopters.

Slated to fly by 2017, the V-280 is engineered to reach speed of 280 knots, achieve a combat range up to 800 nautical miles and perform in what’s called “high-hot” conditions — described as 95-degrees Fahrenheit and 6,000-feet.
