First CH-53K Prototype Heavy Lift Helicopter Delivered To Flight Test Team

The team developing the Sikorsky CH-53K heavy lift helicopter for the U.S. Marine Corps has delivered the first prototype aircraft -- the Ground Test Vehicle (GTV) -- from the assembly line to the flight test team. The move will enable Sikorsky to prepare and test the GTV aircraft for hundreds of hours of powered ground checks ahead of the four follow-on flight test helicopters that will take to the skies during 2014-15.
