The most powerful helicopter ever fielded by the U.S. was just delivered to the Marine Corps.

The CH-53K King Stallion aircraft touched down at Marine Corps Air Station New River in Jacksonville, North Carolina on Wednesday.

The helicopter, which has been in development since 2006, will replace the Marine Corps' nearly 40-year-old CH-53E Super Stallion fleet.

Wednesday's delivery is the first of an expected 200 aircraft from Sikorsky, a unit of Lockheed Martin. The CH-53K is not only considered the most powerful but also one of the more expensive with a recurring flyaway cost of $87 million.
