History
Early years
The squadron was formed 1 June 1928, and designated Headquarters Detachment 7M in San Diego, California. The squadron was re-designated several times in the next decade. It received the designation Marine Utility Squadron 252 (VMJ-252) on 1 July 1941, and Marine Transport Squadron 252 (VMR-252) on 1 April 1945.
In July 1946, VMR-252 was based at MCAS Miramar as part of Marine Aircraft Group 25. They remained there until 14 October 1946 when they were moved to MCAS El Toro.[2] During October 1961, the KC-130 Hercules became the squadron's aircraft. With the introduction of the KC-130, the squadron's primary mission was changed to aerial refueling. On 1 February 1962, the Squadron received its present designation as Marine Aerial Refueler Transport Squadron 252 (VMGR-252). In December 1965, the KC-130 was used to refuel the CH-3 helicopter. This was the first time that a tanker drogue system was used to refuel a helicopter.
The late sixties and early seventies found VMGR-252 actively supporting U.S. Forces in the Republic of Vietnam, transporting essential equipment, parts, and personnel. VMGR-252 also supported the introduction of the AV-8A Harrier. In August 1973, VMGR-252 was involved in the development of safe and standardized aerial refueling procedures to be used with the Harrier.
The Gulf War and the 1990s

In December 1988, VMGR-252 surpassed 300,000 accident free flight hours and won the distinction of achieving the most accident-free flight hours of any squadron in the Marine Corps and Navy.
With little down time the squadron found itself facing an even greater challenge with the mobilization of forces for Operation Desert Shield. Six squadron aircraft were deployed to form VMGR-252 Detachment Alpha. When Operation Desert Storm commenced on 16 January 1991, the detachment transitioned to combat operations and provided over 10 million pounds of fuel to strike aircraft during the course of 937 combat sorties.
After the attacks on 11 September 2001, VMGR-252 formed the backbone of logistical and assault support operations during Operation Enduring Freedom in Afghanistan and provided similar support for the 26th Marine Expeditionary Unit in Iraq during Operation Iraqi Freedom in the spring of 2003. Approximately 30% of the squadron has been continuously deployed in support of Operation Iraqi Freedom since 2003.[3]
In December 2002 VMGR-252 was equipped with three KC-130 J-model aircraft.
