MCAS New River is the principal USMC helicopter operating location on the East Coast, and supports aircrew training in the H-53 helicopter. It is also the evaluation and prospective beddown site for the V-22 Osprey. Helicopter airspace requirements are limited and have not been a constraint in the past; Osprey SUA requirements have not been definitively stated. MCAS New River has been a helicopter support facility since 1954. MCAS New River manages two OLFs, MCOLF Oak Grove and MCOLF Camp Davis, both uncontrolled helicopter facilities.
