Marine Heavy Helicopter Squadron 366 and Marine Light Attack Helicopter Squadron 467 are scheduled to return to Marine Corps Air Station New River in 2014, after a new hangar is built for the MV-22B Osprey squadrons there, making enough room to fit all of the 2nd Marine Aircraft Wing’s rotary wing assets on one air station. The hangar is estimated to cost $141 million and will be the largest Marine Corps building on the East Coast.
