Lieutenant Colonel Hutchinson’s VMF(N)-513 pilots soon established an enviable record for Marine aviation, netting by 31 January five enemy jets without loss of a single F3D. In addition to the jets, the squadron downed a piston engine plane and scored a probable destruct on another. During its first three months of operations with the Douglas Skyknights--the first Navy-Marine jet night-fighter to arrive in the Korean combat theater--the squadron earned two night-kill records. It also quickly proved the design theory and proposed tactics for the Skyknights that enemy aircraft could be located, intercepted, and destroyed purely by electronic means. While on a night combat air patrol in the vicinity of Sinuiju airfield early on 3 November, Master Sergeant H. C. Hoglind picked up a contact on his intercept radar, which a ground radar station had passed on to him, and notified the pilot, Major William T. Stratton, Jr. After losing and reestablishing radar contact, Major Stratton made a visual sighting of a jet exhaust straight ahead. When he had been cleared to proceed, the Flying Nightmare’s pilot sent three bursts of 20mm into the other plane, identified as a YAK-15. Three explosions followed and the aircraft plunged towards the airfield directly below. This marked the first time that an enemy jet had been destroyed at night by use of airborne intercept radar equipment in a jet fighter. Five days later the team of Captain Oliver R. Davis and Warrant Officer Dramus F. Fessler bagged the first MIG-15 for the squadron. Captain Davis expended only 20 rounds of 20mm cannon fire in his aerial victory, which took place northwest of Pyongyang near the Yellow Sea. The next two months brought new distinction to Marines in -513. Shortly after dark on 10 December, First Lieutenant Joseph A. Corvi had departed on a night combat patrol mission. About 35 miles northwest of Chinnampo, his radar operator, Master Sergeant D. R. George, picked up a target on his scope. Since the “bogey” (an unidentified aircraft, believed to be hostile) was three miles distant, the pilot quickly closed on the contact and shot it down. Almost immediately another blip appeared on the radar screen. Lieutenant Corvi turned to the new attack and began approaching it, but because of the slower speed of the enemy plane the Marine pilot was able to fire only one short burst before overtaking it. An instant before passing the enemy aircraft, Lieutenant Corvi saw it disappear from the radar screen, but neither member of the Flying Nightmares crew had made a visual sighting with the plane itself, listed as a probable kill. What these two Marines had accomplished with their earlier encounter was the first attempt to destroy an enemy aircraft without use of a visual sighting by means of lock-on radar gear.
