Origins
The C-17 Globemaster III is a military transport aircraft developed by McDonnell Douglas, now part of Boeing. The development of this high-wing, four-engine, T-tailed aircraft began in the early 1980s as a response to the U.S. Air Force’s need for a large military transport aircraft that could replace the ageing C-130 Hercules and C-141 Starlifter.
The origin of the C-17 Globemaster III dates back to the 1970s when the U.S. Air Force identified a need for a new military transport aircraft that was versatile, reliable, and capable of rapidly delivering troops and supplies to forward bases.

In 1980, the Cargo-Experimental (C-X) program began, which called for design proposals from several aviation manufacturers. The goal was to produce a new aircraft that could carry more cargo, fly faster and farther, and land on and take off from shorter runways than the existing fleet.
The McDonnell Douglas Corporation was one of several companies that submitted designs for consideration. Their proposal was an evolution of the earlier C-15 design, which itself was a development from the YC-14. In 1981, the McDonnell Douglas’ design was chosen, and the development of the aircraft, then known as the C-17, began.
The first flight of the C-17 took place on September 15, 1991. The aircraft was named “Globemaster III” after the C-74 Globemaster and C-124 Globemaster II transport planes that had served the Air Force in the past.
Despite the successful first flight, the C-17 program experienced significant problems in the early 1990s, including cost overruns and issues with wing flaps, leading to congressional investigations.
However, McDonnell Douglas and the Air Force persevered with the program, implementing various technical fixes and management changes to bring the program back on track.
The C-17 Globemaster III was finally delivered for operational use in January 1995. Its excellent performance in operational service, including its unique ability to use small, austere airfields, quickly led to additional orders from the U.S. Air Force and multiple other international customers.

In 1997, Boeing merged with McDonnell Douglas, taking over production of the C-17.
As of my knowledge cutoff in September 2021, the production of the C-17 Globemaster III has ended, with 279 aircraft having been delivered. It continues to serve as the backbone of the airlift forces of the U.S. Air Force and several allied nations around the world.
Operational Service
The primary function of the C-17 is the rapid and reliable transport of troops and cargo. It boasts a spacious cargo hold capable of accommodating a wide variety of loads, including an M1 Abrams tank, three Stryker armoured vehicles, or up to 102 paratroopers.
Its versatility has played a crucial role in global U.S. military operations, such as Operation Enduring Freedom in Afghanistan and Operation Iraqi Freedom.
The Globemaster’s capabilities also extend beyond traditional military operations. The aircraft’s ability to take off and land on short, austere runways makes it perfectly suited for humanitarian missions in hard-to-reach areas.
From disaster relief to emergency medical evacuations, the C-17 has been at the forefront of numerous humanitarian missions. Following natural disasters such as earthquakes, tsunamis, and hurricanes, C-17s have delivered life-saving supplies and aid to communities around the globe.
It also has the ability to perform tactical airlift and airdrop missions, as well as transporting and resupplying troops directly to the battlefield. Its advanced digital avionics system, combined with its design for a crew of just three — a pilot, co-pilot, and loadmaster — allows for precision operations in challenging environments.
Perhaps one of the most impressive operational uses of the C-17 is the technique known as strategic brigade airdrop. This operation involves multiple C-17s flying in formation to drop an entire brigade combat team with their necessary equipment to a designated location.
This capability allows the U.S. military to respond rapidly to emerging threats and crises.
The C-17 has a robust design and the ability to fly long distances. It is equipped with in-flight refuelling capabilities, allowing for non-stop missions to virtually any part of the globe. Its four Pratt & Whitney F117-PW-100 engines provide the power necessary to carry up to 170,900 pounds of payload and reach a top speed of 450 knots.
It has also been instrumental in delivering aid to regions affected by natural disasters or conflict. Also, thanks to the ability to land on short, rough runways it is able to reach remote and austere locations that are often inaccessible to other aircraft. The Globemaster III has participated in countless humanitarian missions, delivering food, medical supplies, and other critical aid.
The C-17 can be equipped for the transportation of wounded or sick personnel. Its wide body can accommodate various medical equipment, including hospital beds and life support systems, enabling it to serve as a flying hospital – the Globemaster really is a do it all aircraft!
RAF Service
Not only has this impressive aircraft served the United States Air Force (USAF) with distinction, but it has also been a crucial asset in the fleet of the United Kingdom’s Royal Air Force (RAF). Let’s delve into the role and impact of the C-17 Globemaster III within the RAF.

The RAF first took delivery of the C-17 in May 2001, initially as a short-term lease to cover a capability gap until the arrival of the Airbus A400M. The C-17s quickly demonstrated their worth, however, prompting the RAF to move from leasing to outright ownership.
The RAF operates a fleet of eight C-17s, all of which are based at RAF Brize Norton in Oxfordshire, serving No. 99 Squadron.
These C-17s, known in RAF service as the “C-17A Globemaster III,” have played a vital role in various global operations, showcasing their strategic airlift capabilities. They are capable of rapid, strategic delivery of troops and all types of cargo to bases throughout the NATO area of responsibility.
They can also transport outsized cargo such as Apache helicopters, and carry out tactical airlift and airdrop missions.
In addition to military operations, the RAF’s C-17s have been pivotal in humanitarian missions. The aircraft’s ability to land on short, semi-prepared airfields makes it an invaluable asset for delivering aid to disaster-stricken areas.
From airlifting British citizens during the 2006 Lebanon conflict to delivering aid after earthquakes in Pakistan and Haiti, the C-17 has been a stalwart in humanitarian efforts.
The C-17’s performance in the RAF has consistently proven its worth. Its range, payload, and flexibility make it a valuable asset to the RAF, with its ability to transport large equipment, supplies, and troops over intercontinental distances and land on short, austere runways.
In the years since its introduction to the RAF, the C-17 Globemaster III has continually demonstrated its versatility, durability, and unparalleled capabilities. Regardless of the mission, whether it’s airlifting heavy equipment, performing medical evacuations, or delivering vital humanitarian aid, the C-17 remains an indispensable workhorse of the RAF.
Its service to the United Kingdom is a testament to the aircraft’s enduring importance in military aviation and humanitarian efforts worldwide.
Conclusion
In its nearly three decades of operational use, the C-17 Globemaster III has proven itself to be an indispensable asset to the USAF and its allied partners.
