The McDonnell Douglas DC-10, a trijet airliner that once dominated the skies, is now a rare sight. But how many DC-10s are still flying as of 2024? Flyermedia.net delves into the current status of this iconic aircraft, highlighting the specific roles and operators that keep a handful of these magnificent planes airborne. We aim to provide aviation enthusiasts and industry professionals with an accurate picture of the DC-10’s presence in today’s aviation landscape, exploring their cargo operations, specialized roles, and potential sightings.
1. What Is The Current Operational Status of DC-10 Aircraft?
Currently, only a limited number of DC-10 aircraft remain operational, primarily serving as freighters or in specialized roles like aerial firefighting and flying hospitals. These aircraft, originally designed for long-range, high-capacity passenger travel, have transitioned to niche applications where their unique capabilities are still valued. The retirement of the KC-10A Extender by the United States Air Force further reduced the number of active DC-10s worldwide. Let’s delve deeper into this topic.
The McDonnell Douglas DC-10 was first introduced in 1971, which met the demands of the long-range and high-capacity travels. It was positioned between the wide-body giants and smaller jets during its era. The plane was known for its distinctive trijet layout, with two engines under the wings and one integrated into the tail. The DC-10 was a popular choice for both passenger and cargo transport due to its range, load capabilities, and suitability for a number of purposes. Throughout its commercial life, the DC-10 was operated by airlines worldwide, including American Airlines, United Airlines, and KLM.
Despite a troubled start due to a series of high-profile incidents in the 1970s, the DC-10 eventually gained a strong reputation for reliability, especially in cargo operations. After McDonnell Douglas ceased production in 1989, many DC-10s continued flying in freighter roles, with some retrofitted as the MD-10 in partnership with FedEx, offering an updated cockpit. The KC-10A Extender, a refueling and transport variant flown by the United States Air Force, was also one of the DC-10’s most enduring roles.
According to research from Embry-Riddle Aeronautical University, the operational lifespan of aircraft like the DC-10 depends heavily on maintenance, utilization, and regulatory factors.

1.1. What Factors Contributed to the Decline in Active DC-10s?
Several factors have contributed to the decline in active DC-10s, including:
- Aging Fleet: As the DC-10 design dates back to the 1960s, the airframes of the remaining aircraft are aging, requiring more frequent and extensive maintenance.
- Fuel Efficiency: Newer aircraft designs offer better fuel efficiency, making them more attractive to airlines looking to reduce operating costs.
- Regulatory Changes: Evolving aviation regulations and safety standards can make it more challenging and expensive to keep older aircraft like the DC-10 in service.
- Retirement of KC-10A: The retirement of the KC-10A Extender by the U.S. Air Force significantly reduced the number of active DC-10s. The Air Force retired its last KC-10A, marking the end of an era for the DC-10 in military service and contributing to the significant decline in active DC-10s worldwide. The type flew its final flight on 26 September 2024, with examples being sent to museums or long term storage.
1.2. How Are the Remaining DC-10s Being Used?
The remaining DC-10s are primarily used in the following roles:

3.1. What Is Aerial Refueling, And Why Is It Important?
Aerial refueling, also known as air-to-air refueling (AAR), is the process of transferring fuel from one aircraft (the tanker) to another (the receiver) during flight. This allows the receiver aircraft to remain airborne for longer periods, extending its range and endurance. Aerial refueling is critical for military operations, allowing fighter jets, bombers, and transport aircraft to reach distant targets or remain on station for extended periods. It is also used in commercial aviation to extend the range of passenger and cargo flights.
3.2. What Modifications Are Required to Convert a DC-10 Into an Aerial Refueling Tanker?
Converting a DC-10 into an aerial refueling tanker requires several modifications, including:
- Installation of Refueling Equipment: The aircraft must be equipped with refueling pods or booms, which are used to transfer fuel to the receiver aircraft.
- Fuel Tank Modifications: Additional fuel tanks may be installed to increase the aircraft’s fuel capacity.
- Structural Reinforcements: The aircraft’s structure may need to be reinforced to support the additional weight of the refueling equipment and fuel.
- Avionics Upgrades: The aircraft’s avionics systems may need to be upgraded to support the refueling mission.
