Marine Medium Helicopter Squadron 562 was the second of two planned UH-34D training squadrons scheduled for activation during 1967. Due to a lack of aircraft and personnel, the squadron remained in a permanent "deferred activation" status, and never stood up.
In the Marine Corps' FY2010 Aviation Plan (Oct 2009), A new MV-22B "Osprey" squadron, to be designated MArine Medium Tiltrotor Squadron 562, was to activate in 2012. Initial plans called for the squadron to be based at MCAS Miramar until 2013, then move to 1st MAW. With the release of the 2010 Force Structure Review, it appears that the planned activation has been cancelled.
