Colonel Charles Barbin “Chuck” DeBellevue (born August 15, 1945) is a retired officer in the United States Air Force. In 1972, while flying during the Vietnam War, DeBellevue became the first Air Force Weapon Systems Officer (WSO) to become a flying "Ace". He was credited with a total of six MiG kills, the most earned by any U.S. aviator during the Vietnam War and is a recipient of the Air Force Cross. In October 1971, DeBellevue was sent to the famed 555th Tactical Fighter Squadron (“Triple Nickel”), of the 432nd Tactical Reconnaissance Wing, at Udorn Royal Thai Air Force Base, Thailand. Flying in a F-4D as the WSO with pilot Capt Steve Ritchie on May 10, 1972, he and Ritchie scored the first of four Mikoyan-Gurevich MiG-21 kills they would achieve together. Both DeBellevue and Ritchie, along with Capt Jeffrey Feinstein of the 13th Tactical Fighter Squadron, 432nd Tactical Reconnaissance Wing, would become the only USAF "aces" during the Vietnam War.
An advantage that the "Triple Nickel Squadron" pilots and WSOs had over other U.S. aircrews was that eight of their F-4D Phantoms had the top-secret APX-80 electronic set installed, known by its code-name "Combat Tree". Combat Tree could read the IFF signals of the transponders built into the MiGs so that North Vietnamese GCI radar could discriminate its aircraft from that of the Americans. Displayed on a scope in the WSO's cockpit, Combat Tree gave the Phantoms the ability to identify and locate MiGs when they were still beyond visual range (BVR). Ritchie and DeBellevue's assignment on May 10, 1972, the first major day of air combat in Operation Linebacker, was as element leader (Oyster 03) of one of two flights of the F-4D MiGCap for the morning strike force. Oyster flight had three of its Phantoms equipped with Combat Tree IFF interrogators, and two days previously its flight lead, Major Robert Lodge, and his WSO 1st Lt Roger Locher had scored their third MiG kill to lead all USAF crews then flying in Southeast Asia.
At 0942, forewarned 19 minutes earlier by the EC-121 "Disco" over Laos and then by "Red Crown", the US Navy radar picket ship USS Chicago, Oyster flight engaged an equal number of MiG-21s head-on, scattering them. Oyster flight shot down three and nearly got the fourth, but fell victim to a MiG tactic dubbed "Kuban tactics" after those of the Soviet WWII ace Pokryshkin, in which a GCI-controlled flight of MiG-19s trailed so that they could be steered behind the American fighters maneuvering to attack the MiG-21s. Maj Lodge was shot down and killed. Lt Locher ejected and was recovered three weeks later. Almost simultaneously Ritchie and DeBellevue rolled into a firing position behind the remaining MiG-21 of the original four with a radar lock, launched two Sparrows and scored a kill with the second.
USAF strike and chaff forces suffered a severe series of losses to MiGs between June 24 and July 5 (seven F-4s) without killing a MiG in return. As a counter-measure, 7th Air Force added a second Disco EC-121 to its airborne radar coverage, positioning it over the Gulf of Tonkin. On July 8, 1972, Ritchie and DeBellevue were leading Paula flight, in gun-equipped F-4Es instead of the Combat Tree F-4Ds they usually flew, on a MiGCAP to cover the exit of the strike force. While they were west of Phu Tho and south of Yen Bai, the EC-121 vectored them to intercept MiG-21s returning to base after damaging one of the US chaff escorts. The MiGs were still approximately 4 miles away and Ritchie turned the flight south to cross the Black River. As they closed, Disco gave them warning that the MiG return had "merged" with the Paula flight's return on his screen. Ritchie reversed course, observed the first MiG at his 10 o'clock position and turned left to meet it head-on.

When he observed the second MiG, which he also passed head-on, he reversed hard left to engage. The MiG turned to its right to evade the attack, an unusual maneuver, and Ritchie used a vertical separation move to gain position on its rear quarter. DeBellevue obtained a solid boresight (dogfighting) radar lock on it while at the MiG's 5 o'clock, although fired from the edge of their flight envelopes, both AIM-7s struck home.
The first MiG had also turned back and was attacking the last F-4 in Ritchie's flight from behind, an often fatal consequence to US aircraft employing the then-standard "fluid four" tactical formation. Ritchie made a hard turn across the curving intercept of the MiG, again coming out at its 5 o'clock, and the MiG, apparently perceiving the threat, broke hard right and dove away. Ritchie fired an AIM-7 from inside its minimum range and at the limit of its capability to turn. Expecting the Sparrow to miss, he was trying to switch to a gun attack in the relatively unfamiliar F-4E he was flying that day when the missile exploded the MiG, 1 minute and 29 seconds after the first kill.
A competition to become the Air Force's first Vietnam "ace" developed between Ritchie and Captain Jeffrey S. Feinstein, a WSO in another one of the 432nd's squadrons, the 13th TFS, who scored his 3rd and 4th kills on July 18 and July 29. Each had a claim denied by Seventh Air Force's Enemy Aircraft Claims Evaluation Board, Ritchie and DeBellevue for a claim of a MiG-21 on June 13, and Feinstein for a claim June 9
Ritchie's final victory (his 5th making him an "Ace") with DeBellevue (his 4th) came on August 28, 1972, while leading Buick flight, a MiGCAP for a strike north of Hanoi. During the preceding month, 7th Air Force had instituted daily centralized mission debriefings of leaders and planners from all fighter wings called "Linebacker Conferences". Ritchie had just started his flight of Combat Tree Phantoms on its return to base (Ritchie and DeBellevue were flying F-4D AF Serial No. 64-7463, in which they had scored their first kill). Red Crown, now the USS Long Beach, alerted the strike force to "Blue Bandits" (MiG-21s) 30 miles southwest of Hanoi, along the route back to Thailand. Approaching the area of the reported contact at 15,000 feet, Ritchie recalled recent Linebacker Conference information that MiGs had returned to using high altitude tactics and suspected the MiGs were high. Buick and Vega flights, both of the MiGCAP, flew toward the reported location.
DeBellevue picked up the MiGs on the Phantom's onboard radar and using Combat Tree, discovered that the MiGs were ten miles behind Olds flight, another flight of MiGCAP fighters returning to base. Ritchie called in the contact to warn Olds flight. Ritchie, concerned that MiGs might be at an altitude above them, made continuous requests for altitude readings to both Disco and Red Crown. He received location, heading, and speed data on the MiGs (now determined to be returning north at high speed to their base) but not altitude as Buick flight closed to within 15 miles of the MiGs. DeBellevue's radar then painted the MiGs dead ahead at 25,000 feet, and Ritchie ordered the flight to light afterburners. DeBellevue warned Ritchie they were closing fast and were in range. About the same time Ritchie saw the MiGs himself headed in the opposite direction.
Attacking in a climbing curve behind the MiG-21's with his AIM-7 guidance radar locked on, Ritchie was given continuous range updates by DeBellevue. With his Phantom barely making enough speed to overtake the targets, Ritchie launched two Sparrows from over four miles away. The firing parameters of the two shots were out of the missiles' performance envelope, an attempt to influence the MiGs to turn and thus shorten the range. Both shots not only missed but failed to influence the opponents. Moments later, tracking one MiG visually by the contrail it was making, Ritchie fired his remaining two Sparrows, also at long range. The first missed, but the MiG made a hard turn and actually shortened the range, and was destroyed by the second. Short on fuel, Ritchie elected not to try to pursue the second MiG-21.
During Linebacker strikes on September 9, 1972, a flight of four F-4Ds on MiGCAP west of Hanoi shot down three MiGs. Two were MiG-19s downed by Capt John A. Madden, Jr. and his WSO Capt DeBellevue. For Madden, the victories constituted his first and second MiG kills, but for DeBellevue they were numbers five and six, moving him up as the leading MiG destroyer of the war and elevating him to "Ace" status. When DeBellevue acquired the MiGs on radar, the flight maneuvered to attack. Madden and DeBellevue made the first move. They got a visual on the MiG about 5 miles out on final approach with his gear and flaps down. Getting a lock on him, they fired missiles but they missed. They were coming in from the side-rear and slipped up next to that MiG no more than 500 feet apart. He got a visual on us, snatched up his flaps and hit afterburner, accelerating out. It became obvious we weren't going to get another shot at the MiG.
DeBellevue describes the next two engagements as follows: "We acquired the MiG's on radar and positioned as we picked them up visually. We used a slicing low-speed yo-yo to position behind the MiG-19's and started turning hard with them. We fired one AIM-9 missile which detonated 25 feet from one of the MiG-19's. We switched the attack to the other MiG-19 and one turn later we fired an AIM-9 at him. I observed the missile impact the tail of the MiG. The MiG continued normally for the next few seconds, then began a slow roll and spiraled downward, impacting the ground with a large fireball."

Madden and DeBellevue returned to their base thinking they had destroyed only the second MiG-19. Only later did investigation reveal that they were the only aircrew to shoot at a MiG-19 which crashed and burned on the runway at Phuc Yen that day. That gave them two MiG-19 kills for the day and brought DeBellevue's total to six MiG kills, the most earned during the war.
During his combat tour, DeBellevue logged 550 combat hours while flying 220 combat missions, 96 of which were over North Vietnam. His skill as a weapon systems officer was recognized when he and the other two Air Force "Aces", Ritchie and Feinstein, received the 1972 Mackay Trophy. He also received the Veterans of Foreign Wars' Armed Forces Award and the Eugene M. Zuckert Achievement Award.
Removed from active combat following his fifth and sixth kills, DeBellevue applied for and re-entered pilot training at Williams AFB, Arizona, in November 1972. After pinning on his new wings, he returned to the F-4 as a pilot assigned to the 49th Tactical Fighter Wing at Holloman AFB, NM. In 1975, he moved to Elmendorf AFB, AK, where he served as the assistant operations officer in the 43d Tactical Fighter Squadron. He went on to serve as the 5th Air Force deputy chief of staff at Yokota AB, Japan. He was then assigned as the commander of the 95th Air Base Wing at Edwards AFB, California, until 1995. The 95th ABW is the host wing at Edwards AFB which is the second largest base in the Air Force.
DeBellevue retired from active duty as a full Colonel while serving as commander of AFROTC Detachment 440 at the University of Missouri in January 1998 after 30 years of military service.
He was the last American ace on active duty.
