A U.S. Air Force KC-46A Pegasus tanker lost its refueling boom over the Atlantic Ocean on July 8, 2025, during a training mission off the coast of Virginia, causing nearly $10 million in damage. The official Accident Investigation Board report, released in June 2026, attributes primary cause to boom operator control inputs but acknowledges a known Category 1 'stiff boom' design flaw as applicable. This marks the fourth midair accident involving the KC-46A since 2022 and the second boom snap-off in a year. The mishap occurred while refueling F-22A Raptors from the 1st Fighter Wing, involving a student pilot with only 13 flight hours who caused three emergency breakaways before the incident. The boom's aft section, including the U-Tail and telescoping tube, fell into the ocean and was never recovered. The article criticizes the pattern of blaming crew members while the underlying defect remains unresolved.
The Defence Blog – Military and Defense NewsUS Air Force Investigation Reveals $10 Million F-22 Refueling Mishap Due to Stuck Boom
A routine aerial refueling mission on July 8, 2025, off the coast of Virginia resulted in nearly $10 million in damage when a KC-46A Pegasus tanker lost its entire refueling boom during an attempt to refuel an F-22A Raptor. According to a US Air Force investigation, the boom nozzle became stuck in the F-22's receptacle due to the boom operator's control inputs and the fighter pilot's excessive closure rate, exacerbated by the KC-46's known 'stiff boom characteristics.' After an emergency breakaway, the boom whipped into the tanker's tail, causing $9,978,567 in damage before falling into the sea. No injuries occurred, but the incident highlights ongoing issues with the KC-46's boom system, which has been linked to at least three prior mishaps between 2022 and 2024.

A U.S. Air Force investigation found that a July 2025 KC-46A refueling boom mishap was primarily caused by the boom operator's incorrect manual control inputs, which led to an excessively out-of-trim boom and a radical force on the nozzle. This caused a nozzle binding event during a breakaway with an F-22A Raptor. The F-22 pilot, a student with only 13 flight hours in the Raptor, failed to account for the stiff boom characteristics, contributing to an excessive closure rate. The boom struck the KC-46A's tail, broke off, and fell into the Atlantic Ocean. The incident caused nearly $10 million in damage to the KC-46A, but no injuries or civilian property damage occurred. The boom operator was a qualified instructor with over 1,000 hours of experience.

A U.S. Air Force investigation found that a KC-46A Pegasus refueling tanker's boom was severely damaged during a July 8, 2025 training mission over the Atlantic Ocean due to two main errors: the boom operator's incorrect manual control inputs caused an excessively out-of-trim boom, leading to a nozzle binding event; and the F-22A Raptor pilot's failure to account for the stiff boom characteristics, resulting in an excessive closure rate. During a breakaway, the bound nozzle caused an unrecoverable boom fly-up, striking the KC-46A's tail and breaking off, falling into the ocean. The boom operator was a qualified instructor with over 1,000 hours, while the F-22 pilot was a student with only 13 flight hours. Damages were estimated at nearly $10 million; no fatalities or injuries occurred.
Military TimesAir Force Faults Crew in Second KC-46 Tanker Accident That Tore Off Boom
A July 2025 midair refueling accident involving a U.S. Air Force KC-46A Pegasus tanker resulted in the refueling boom being torn off and falling into the Atlantic Ocean, causing nearly $10 million in damage. An investigation report released last week primarily blamed the boom operator for applying excessive force to the controls as a student F-22 pilot made a shaky approach. However, the report also cited a known design flaw called 'nozzle binding'—a category 1 discrepancy—as a contributing factor. This was the fourth such incident since 2022 involving stuck KC-46 probes, with two previous accidents also resulting in boom loss. The 2025 accident occurred during a training flight off the coast of Virginia, involving aircraft from McConnell Air Force Base and Langley Air Force Base. The report noted the operator had over 1,000 flight hours but made critical control errors, while the student pilot had only 13 hours in the F-22.
Task & PurposeAir Force Faults Crew in Second KC-46A Tanker Accident That Tore Off Boom
A July 2025 midair collision during a training mission tore the refueling boom off a KC-46A Pegasus tanker over the Atlantic Ocean, marking the second such incident in 11 months. An Air Force investigation primarily blamed the boom operator for applying excessive force to the controls, causing the boom to become stuck in an F-22's fuel port and then slam into the tanker before breaking free. The report also cited 'nozzle binding,' a known category 1 defect in the KC-46's refueling system, as a contributing factor. The F-22 student pilot was partly faulted for a shaky approach. The accident caused nearly $10 million in damage. A similar 2024 incident was also blamed on crew error, while a 2022 near-miss was attributed to system deficiencies. Separately, a GAO report highlighted ongoing fuel system problems across the KC-46 fleet.
Task & PurposeAir Force Faults Crew in Second KC-46 Tanker Accident That Tore Off Refueling Boom
A July 2025 midair refueling accident involving a U.S. Air Force KC-46A Pegasus tanker resulted in the refueling boom being torn off and falling into the Atlantic Ocean, causing nearly $10 million in damage. An Air Force investigation primarily blamed the boom operator for applying excessive force to the controls as a student F-22 pilot made an unstable approach. However, the report also cited a known design flaw called 'nozzle binding'—a Category 1 discrepancy—that has contributed to four similar mishaps since 2022, including two previous boom-severing accidents. The nozzle binding issue makes the refueling probe too stiff when contacting receiver aircraft. While the 2025 and 2024 accidents primarily blamed aircrew errors, a 2022 incident absolved the crew and faulted the KC-46's control system. Combined damages from the three accidents total approximately $32 million.
Task & PurposeBoom Operator and F-22 Pilot Errors Combined in $10 Million KC-46 Mishap
An Air Force Accident Investigation Board report determined that a combination of errors by a KC-46 boom operator and an F-22 pilot caused a $10 million mishap on July 8, 2025, over the Atlantic Ocean. The boom operator made incorrect control inputs that put the boom 'out of trim,' while the F-22 pilot, a student with only 13 hours in the aircraft, failed to properly manage the KC-46's known 'stiff boom' deficiency. During a training mission involving seven F-22s, the refueling connection became bound. When the F-22 broke away, the boom jerked upward, struck the tanker's tail assembly, and broke in half. The boom operator's actions were deemed the primary cause, but the F-22 pilot's failure to reduce power after contact was a substantial contributing factor. The KC-46's stiff boom was also cited as a contributing factor.
Air & Space Forces MagazineBoom Operator and F-22 Pilot Errors Combined in $10 Million KC-46 Mishap
An Air Force Accident Investigation Board report published June 12 determined that a combination of human errors and a known aircraft deficiency caused a $10 million mishap involving a KC-46 refueling tanker and an F-22 Raptor on July 8, 2025. The incident occurred during a training mission over the Atlantic Ocean, where the KC-46 was scheduled to refuel seven F-22s. The boom operator, a qualified instructor with over 1,000 flight hours, made incorrect control inputs that put the refueling boom 'out of trim.' Meanwhile, the F-22 pilot, a student with only 13 hours in the aircraft, failed to properly manage the tanker's known 'stiff boom' deficiency by not reducing power after making contact, causing the receiver to drift forward. These combined errors caused the boom to become bound. When the boom disconnected, it suddenly jerked upward, struck the KC-46's tail assembly (damaging the tail cone, APU exhaust, and the boom itself), and then broke in half, plunging into the ocean. The report cited the boom operator's inputs as the primary cause and the pilot's actions as a substantially contributing factor.
