Marine Fighting Squadron 512 (VMF-512) was a fighter squadron of the United States Marine Corps during World War II. The squadron was aircraft carrier based during the last year of the war and supported combat operations during the Battle of Okinawa and the Battle of Balikpapan (1945). Following the end of World War II they were deactivated on 10 March 1946 and remain in an inactive status today.
Training quickly resumed at MCAS Mojave and on 5 November 1944 the squadron was re-designated as Marine Fighting Squadron (Carrier Squadron) (VMF(CVS)-512) denoting that the squadron was now Aircraft carrier based. On 8 December 1944, VMF-512 was transferred to Marine Air Support Group 48 (MASG-48) at Marine Corps Air Station Santa Barbara, California where it continued training until it went aboard the USS Gilbert Islands (CVE-107) in March 1945 for a shakedown cruise and carrier-landing practice. For their initial cruise VMF-512 was paired with VMTB-143 to form Marine Carrier Group 2 (MCVG-2). After their training cruise the squadron departed San Diego on 12 April 1945 for exercises in Hawaiian waters.
The USS Gilbert Islands arrived off the coast of Okinawa, Japan on 21 May. During the Battle of Okinawa VMF-512 aircraft blasted and strafed concrete dugouts, troop concentrations, ammunition and fuel dumps on Okinawa from 24–31 May. In the following days they helped neutralize outlying Japanese airfields and installations, including the Sakishima Islands with repeated bomb and rocket attacks. Later in June, the USS Gilbert Islands departed for Leyte, in the Philippines. Soon thereafter they sailed to support operations in Borneo.
During the Battle of Balikpapan VMF-512 provided close air support for the Australian7th Division. The squadron remained carrier based and at the end of World War II was operating at sea near Tokyo. As part of the post-war drawdown of forces, VMF-512 was decommissioned on 10 March 1946.
