By 20 April the three tactical squadrons of MAG-12--VMF(N)-513, VMF-212, and VMF-323--had completed their relocations on the Korean west coast. Two days later, combined MAG-12 attack and -33 jet aircraft participated in what was a Fifth Air Force one-day combat record: 1,049 sorties. One MAG-33 unit, the newly-formed Marine Photographic Squadron 1, was already flying a large number of aerial reconnaissance missions directed by Fifth Air Force. It provided almost one-third of the daylight photo effort required by FAF with but one-quarter of the aircraft.[56] VMJ-1’s complement of a dozen 550 mph McDonnell twin-jet Banshee F2H-2P aircraft mounted three cameras and were capable both of high altitude work and good speed. Introduction of this single-seat jet was considered the “first important development in aerial photography in the Korean War,”[57] since the Banshee could outproduce any photo plane in Korea.

This record was established despite the fact that the Marine squadron, with 10 jets, flying out of K-3 (Pohang) was more than 150 miles further from most targets than the other major photo unit, the 15th Tactical Reconnaissance Squadron of the 67th Tactical Reconnaissance Wing, based at K-14 (Kimpo).

On 11 April at K-3, General Schilt turned over wing responsibility to Brigadier General Clayton C. Jerome. Among the numerous civilian and military dignitaries attending the ceremony at the Pohang 1st MAW headquarters were the Honorable John J. Muccio, U.S. Ambassador to Korea; Air Force Lieutenant Generals Otto P. Weyland and Frank F. Everest, commanders of FEAF and FAF respectively; and the Marine division CG, Major General Selden. The new wing commander, General Jerome, like his predecessor, had a distinguished flight career. A 1922 graduate of the Naval Academy, he had served in various foreign and U.S. aviation billets and was a veteran of five World War II campaigns. In 1943 Colonel Jerome was operations officer for Commander, Aircraft, Solomon Islands. Later he was named Chief of Staff, Commander, Aircraft, Northern Solomons and Commander, Aircraft and Island Commander, Emirau, in the northern Solomons. Before returning to the States, Colonel Jerome had participated in the recapture of the Philippines, commanding MAG-32 and directing all Marine air support in the Luzon fighting. Brigadier General Jerome became Director of Aviation and Assistant Commandant of the Marine Corps for Air in September 1950 and served in this capacity until taking command of the 1st Marine Aircraft Wing in Korea.[58] [58] DivInfo, HQMC, Biography of LtGen Clayton C.
