14 January 1973: A McDonnell F-4B-28-MC Phantom II, Bu. No. 153068, flown by Lieutenant Victor T. Kovaleski and Ensign D.H. Plautz of VF-161 Chargers, from the aircraft carrier USS Midway (CVA-41), was hit by 85 mm anti-aircraft artillery approximately 10 miles (16 kilometers) south of Thanh Hóa, North Vietnam. The aircraft began leaking fuel and after flying offshore, the crew ejected. Both men were rescued.
This was the very last United States aircraft lost to enemy action during the Vietnam War.
Two days earlier, Lieutenant Kovaleski and Lieutenant James R. Wise, flying 153068, had shot down a Vietnam Peoples Air Force MiG 17 flown by Senior Lieutenant Luu Kim Ngo, near Hải Phòng, using an AIM 9 Sidewinder heat-seeking air-to-air missile. This was the last air combat victory by a U.S. airplane during the Vietnam War.
On 18 May 1972, F-4B Bu. No. 153068, flown by Lieutenants Henry A. (“Bart”) Bartholmay and Oran R. Brown, on their first combat mission over North Vietnam, shot down an enemy MiG 19 fighter with an AIM-9 Sidewinder near Kep Airbase, northeast of Hà Nội, North Vietnam.
7 July 1965: The McDonnell Aircraft Corporation delivered the 1,000th production F-4 Phantom II, an F-4B, to the United States Navy. Phantom II MSN 1034 was an F-4B-23-MC Phantom II, assigned Bureau of Aeronautics serial number (“Bu. No.”) 152276.
The fighter was assigned to Marine Fighter Attack Squadron 314 (VFMA-314), the “Black Knights,” at Da Nang Air Base, Republic of South Vietnam. On the morning of 24 January 1966, Bu. No. 152276 was flown by Captain Doyle Robert Sprick, USMC, with Radar Intercept Officer 2nd Lieutenant Delmar George Booze, USMC, as one of a flight of four F-4s assigned to drop napalm on a target 7 miles (11 kilometers) southwest of Hue-Phu Bai.
At 10:05 a.m., Captain Albert Pitt, USMC, flying F-4B-22-MC Bu. No. 152265, with RIO 2nd Lieutenant Lawrence Neal Helber, USMC, radioed that he, in company with Captain Sprick, was off the target and returning to Da Nang.
Neither airplane arrived. A search was started at 11:00 a.m. The two-day search was unsuccessful. It is presumed that the two Phantoms collided. All four aviators were listed as missing, presumed killed in action.
