History
Flight-testing of the MV-22 Osprey was delayed in the aftermath of the two incidents in 2000 and resumed in May 2002 to address the mechanical issues raised by these accidents. Included in the now on-going testing process is a rigorous, strictly regimented inspection process to verify and validate all of the aircraft’s modifications and clearances. The Integrated Test Team at Naval Air Station Patuxent River, Edwards Air Force Base, VMX-22, and the Bell Helicopter facility in Amarillo, Texas, have flown more than 4600 hours in the MV-22. Since the MV-22 is neither a fixed-wing nor rotary-wing platform, it has a unique designation as a tiltrotor. The aeromechanics, composite structure, maintenance concepts, and concept of deployment are inherently unique and best addressed in a squadron solely focused on tiltrotor operational testing. On July 11, 2014, Marines from VMX-22 accompanied  on her maiden voyage from Mississippi, en route to her homeport in San Diego, California. In June 2015, the Command Element and MV-22 component relocated to Marine Corps Air Station Yuma from Marine Corps Air Station New River. In August 2015, the Light Attack (UH-1Y, AH-1W, and AH-1Z) component and the Aviation Command and Control component relocated to Marine Corps Air Station Yuma from Naval Air Weapons Station China Lake and Camp Pendleton, CA, respectively. On May 13, 2016 VMX-22 was re-designated as VMX-1. In October 2019, the F-35B Testing Detachment stationed on Edwards Air Force Base, California moved to MCAS Yuma, Arizona. See also
