The United States military is investigating after a KC-135 Stratotanker aerial refuelling aircraft crashed during operations in western Iraq, according to officials from US Central Command (CENTCOM).

In a statement, CENTCOM confirmed the aircraft was lost during a mission conducted as part of Operation Epic Fury. Two aircraft were involved in the operation, with one tanker crashing while the second aircraft landed safely.

Officials said the incident occurred in what the military described as 'friendly airspace' and confirmed the crash was not caused by hostile or friendly fire. The cause of the incident has not yet been determined and rescue efforts are under way to determine the status of the crew members on board.

Search and Rescue Operations

US military search and recovery teams have been deployed to the crash area in western Iraq as part of ongoing rescue operations. CENTCOM said additional air and ground assets are supporting efforts to locate the aircraft and assess the crash site.

Officials have not confirmed how many personnel were aboard the aircraft at the time of the incident. The military said the identities of crew members will not be released until their families have been notified.

What Is a KC-135 Stratotanker?

The Boeing KC-135 Stratotanker is a military aircraft designed to refuel other planes while they are in flight, effectively acting as a 'flying fuel station'. Developed from Boeing's 367-80 prototype — the same platform that led to the Boeing 707 passenger jet — the aircraft entered US Air Force service in 1957.

According to technical specifications from the US Air Force, Its primary mission is to extend the range and endurance of fighter jets, bombers and surveillance aircraft by transferring fuel through a rigid 'flying boom' system controlled by a specialist crew member positioned in the rear of the plane.

Crew and Refuelling Operations

A standard KC-135 mission is typically operated by three crew members consisting of a pilot, a co-pilot and a boom operator, though additional crew may be carried depending on the mission profile. The aircraft can transfer up to 200,000 pounds (around 90,700 kilograms) of fuel to other aircraft during flight and can travel at speeds of roughly 530 miles per hour with a maximum altitude of around 50,000 feet.

Aerial refuelling missions require aircraft to fly in close formation while fuel is transferred mid-air. The aircraft can carry large quantities of fuel and is capable of supporting multiple aircraft during long-range operations.

Tankers in Middle East Operations

Aerial refuelling aircraft such as the KC-135 are routinely used in military operations across the Middle East to support long-range air missions. Tankers allow fighter jets and surveillance aircraft to remain airborne for extended periods without returning to base for fuel.

US military aircraft frequently operate across Iraq, Syria and surrounding regions where large distances between bases make aerial refuelling essential for sustained operations. Officials said more details about the crash are expected once rescue operations and the initial investigation are completed.

Investigation Into the Crash

Military investigators will examine flight data, operational records and maintenance logs to determine what caused the crash. Officials have not yet indicated whether mechanical failure, operational factors or environmental conditions may have contributed to the incident.

The investigation will also review communications and mission details from Operation Epic Fury to establish the circumstances surrounding the loss of the aircraft.
