What will replace the uh 60

The Army also awarded a contract to a Textron-Bell team, which built the V Valor, a tiltrotor-design helicopter that completed its first test flight in December The Defiant's test flight at knots "is just a number, but it's a number that you are not typically accustomed to hearing with respect to a helicopter," Bill Fell, a former Army aviator and test pilot in the Defiant program, said. The Defiant was designed to fly at a minimum speed of knots, "so we will go well in excess of that, in excess of knots," Fell said.

The Defiant program has spent many hours testing the engine and other systems on the ground in a special test stand designed to collect data and predict how the prototype will perform during flight. Randy Rotte, director of business development for Boeing Cargo Helicopters and Future Vertical Lift, said he is confident that Defiant will give aviators what they need to survive in the "most lethal and complicated battlefields today and in the future.

The helicopter also uses other technologies to improve speed, range, and survivability. Read This. This content is imported from YouTube. Type keyword s to search. Today's Top Stories. The two aircraft differ radically from conventional helicopter designs to offer greater speed. The winner of the competition will enter service in Some More Badass Helos. Ian Hitchcock Getty Images.
