Short Description

RAF Mildenhall is located in the eastern part of the United Kingdom, within the county of Suffolk, near the small market town of Mildenhall. The surrounding area is predominantly rural, characterized by expansive agricultural land, open countryside, and small villages, while still benefiting from efficient transport links to regional centers such as Cambridge.

This combination of low population density and well-developed infrastructure provides favorable conditions for the operation of a major air base. RAF Mildenhall serves as a key installation for the U.S. Air Force in Europe, supporting missions in air refueling, air mobility, and special operations. Together with other nearby facilities, the base forms an essential part of the American military presence in the United Kingdom.

RAF Mildenhall benefits from its strategically favorable location on the western edge of Europe, enabling efficient air operations and logistical support across the continent. Its position in the United Kingdom also allows for direct access to key flight routes toward regions of strategic importance, including Northern and Eastern Europe, as well as Africa and the Middle East.

In addition, RAF Mildenhall maintains strong transatlantic connections with the United States, reinforcing its role as an important hub for air refueling operations, rapid deployment, and global mobility missions. This connectivity supports both U.S. Air Force and NATO objectives, particularly in the areas of force projection, logistical sustainment, and allied cooperation.

Historical Summary

RAF Mildenhall has a long and distinguished history that reflects the broader development of military aviation in Europe. The airfield was originally constructed in the 1930s and officially opened in 1934 as a station of the Royal Air Force. In its early years, it served primarily as a bomber base and quickly became an important site for long-range operations.

During World War II, RAF Mildenhall played a significant role in British air operations, supporting bomber missions over occupied Europe. The base was used by several RAF squadrons and contributed to the Allied war effort through strategic bombing and reconnaissance missions.

Following the war, the strategic importance of the base continued to grow. In 1950, RAF Mildenhall was made available to the United States Air Force as part of expanding transatlantic defense cooperation during the early years of the Cold War. Since then, it has served as a key hub for U.S. air operations in Europe.

Throughout the Cold War period, the base supported a wide range of missions, including reconnaissance, air refueling, and logistical operations. Its role became especially important in maintaining a forward U.S. presence in Europe and ensuring rapid response capabilities.

In the decades that followed, RAF Mildenhall continued to evolve. It played a part in numerous international operations, including support for missions in the Middle East, the Balkans, and Africa. Today, the base remains a vital installation for U.S. Air Forces in Europe, particularly in the areas of air mobility and aerial refueling, and stands as a symbol of enduring cooperation between the United Kingdom and the United States.

Based units and aircraft

RAF Mildenhall hosts several key units of the United States Air Force, primarily focused on air refueling, special operations, and rapid global mobility.

The base is home to the 100th Air Refueling Wing, known as the “Bloody Hundreth” operates 15 Boeing KC-135 Stratotanker and provides critical air-to-air refueling support for U.S. and allied aircraft across Europe and beyond.

In addition, RAF Mildenhall supports units of the 352nd Special Operations Wing, flying aircraft such as the CV-22 Osprey and Lockheed MC-130J Commando II, which are used for special operations missions including infiltration, exfiltration, and aerial refueling of special forces. The CV-22B Osprey are assigned to the 7th Special Operations Squadron (SOS) while the MC130J fleet is assigned to the 67th SOS. The special ops aircraft are maintained by the 352nd Special Operations Maintenance Group.

Together, these units and aircraft make RAF Mildenhall a key hub for U.S. Air Forces in Europe.

Deployments

As well as permanently based aircraft, RAF Mildenhall also hosts deployments most of the time. Typically, one RC-135 variant from Offutt Air Force Base operates sorties from EGUN for several months before heading home and being replaced by another.

The latest addition to RAF Mildenhall is the deployment of a C-146 Wolfhound belonging to the Air Force Special Operations Command (AFSOC).

Common visitors

RAF Mildenhall is one of the busiest US air bases in Europe. As a result, you can often find aircraft such as the C-130, C-17 and C-5 transporting cargo and personnel to and from EGUN. Since more and more KC-46s are being built, they are also becoming a common sight during fuel stops while dragging fighter jets across the Atlantic.

Special Movements

As EGUN is the United States’ most north-westerly airbase in Europe, it is often used by various aircraft types to refuel before or after crossing the Atlantic, such as different types of C-130, like the EC-130H Compass Call. Other nations sometimes use RAF Mildenhall too, just like the Royal Air Force for training, the Royal Australian Air Force for a stopover or some Qatari F-15QA’s on their delivery flight.

Future Plans

RAF Mildenhall is expected to remain a major long-term U.S. Air Force hub in Europe. Current plans point toward modernization and expanded strategic importance rather than downsizing.

Key points:

• The base plays a central role in aerial refueling, special operations, reconnaissance, and rapid troop deployment.
• The U.S. Air Force is restructuring its European operations, and Mildenhall is considered a key logistics and operational hub.
• Since the war in Ukraine, the U.S. has increased — not reduced — its military focus in Europe.
• RAF Mildenhall and nearby RAF Lakenheath are widely expected to remain important U.S. bases for decades.
• Earlier ideas to reduce or relocate operations from Mildenhall were cancelled years ago.
