R.A.F Mildenhall in Suffolk is home to the United States Air Force European Tanker Task Force, flying the Boeing KC-135R Stratotankers of the 100th Air Refuelling Wing. Also based there is the 352nd Special Operations Group equipped with the Lockheed MC-130 Hercules. In July 2011 Jetwash Aviation Photo's was given exclusive access to the based units, along with the opportunity to participate in an air-to-air refuelling mission in one of the 100th ARW's tanker aircraft operating an "Operation Unified Protector" mission in support of the "no-fly zone" over Libya.

The 100th Air Refueling Wing (100th ARW) is RAF Mildenhall's current host unit and is the only permanent United States air refueling wing based in the European theatre. With the 351st Air Refuelling Squadron (351ARS) being the subordinate unit, it was activated here on 1st February 1992. Prior to that, the KC-135's seen at Midenhall were drawn from a variety of Stateside based units working on a Temporary Duty (TDY) rotational basis under the auspices of Srategic Air Command's 306th Strategic Wing. The 100th ARW now provides the critical air refueling bridge that allows the 'Expeditionary Air Force' to deploy around the globe at a moments notice. The 100th Air Refueling Wing conducts air refueling and combat support operations throughout the European and African areas of responsibility, refuelling both U.S. and NATO military aircraft over a span of more than 20 million square miles with its fleet of fifteen KC-135R Stratotankers.
The unofficial motto - No-one Kicks Ass Without Tanker Gas!

58-0016 (left) sports the Multi-Point Refuelling System (MPRS) that can be carried by the 100th ARW Stratotankers. The pods allow refueling of U.S. Navy, U.S. Marine Corps and most NATO tactical jet aircraft, whilst retaining the standard tail mounted refueling boom. The pods themselves are Flight Refueling Limited MK.32B models and allow the tanker to refuel two receivers at the same time, increasing output of fuel flow when compared to the single drogue adapter that can be fitted to the boom. It also, and more importantly allows refuelling of both types of receiver aircraft during one mission.

You can read an in depth report on our Operation Unified Protector mission with the 351ARS here:-

Over fifty years ago, the Boeing KC-135 Stratotanker was designed from the Boeing 367-80 model and was first 'rolled out' of the Renton plant on 20th July 1956, its first flight being completed on 31st August. Operational service commenced on 30th April 1957 with the 93rd Air Refuelling Squadron at Castle AFB in Merced, California. Designed to meet SAC's requirement for a tanker/transport aircraft, 820 Boeing C-135 variants were built over a ten year production run, of which 749 KC-135's were built for the US Air Force as A & B models. Todays KC-135R model is a re-engined variant designed to give a much needed power boost, along with increased service life, better performance and fuel economy, together with reduced maintenance costs and compliance with modern day noise restrictions. After assessment of various engines the General Electric/SNECMA CFM-56 was selected and the first KC-135R aircraft was 'rolled out' at Boeing's Witchita modification facility on 22nd June 1982, with the first unit (384th ARW at McConnell AFB) receiving its aircraft in June 1984. Numerous other modifications took place during the upgrade, including larger stabilisers, revised wing leading edges, wing and fuselage re-inforcements, new yaw damper and rudder actuators and strengthened landing gear. Each CFM-56 engine provides an impressive increase in thrust of 22,000lb compared to the A-models original J-57 engines which produced only 13,750lb each.

The boom consists of two telescopic sections that can extend to a length of 27 feet and can be moved between 12.5 and 50 degrees in the vertical and 30 degrees left or right from the centre position. To guide receiver aircraft, the KC-135's are equipped with two rows of lights under the fuselage, along with coloured markings on the boom itself, which indicate whether the receiver needs to move forward or backward and up or down so as to be in the correct postion to receive fuel from the boom.

In 2009, the U.S Air Force selected Rockwell-Collins for the engineering, manufacturing and development phase of the C/KC-135 Block 45 cockpit upgrade programme. Under the contract, Rockwell-Collins modernized the KC-135 tankers flight deck with the latest generation auto-pilot, flight director, radar altimeter and electronic engine instrument display. The programme was completed in July 2011.

The normal crew on a KC-135R is made up of the pilot, co-pilot and boomer/loadmaster (who also doubles up as a radio operator if required). Each wing houses two primary fuel tanks, plus a reserve tank in each wing and a larger tank housed in the wing centre section. There are also nine fuel cells mounted under the cabin floor. The "Boomer" operates the system from a pod under the rear fuselage, with access being gained through two openings in the floor at the rear of the fuselage. There are three 'beds' in the compartment, the centre one being used by the Boomer and the outer ones each side of the central one being used by instructors, students, or of course photographers!

The 352nd Special Operations Group is the air component for special operations within the the United States Air Force European command. Under the operational control of the commander for Special Operations Command Europe (SOCEUR), the group plans and executes general war and contingency operations using MC-130H Combat Talon II and MC-130P Combat Shadow aircraft. The 352nd SOG use their advanced aircraft, tactics and air refueling techniques to infiltrate, exfiltrate, and re-supply special operations forces.
Two flying squadrons operate under the 352nd SOG, the first being the 7th Special Operations Squadron (Air Commandos) operating the MC-130H Combat Talon II, executing night, adverse weather, long-range insertion, extraction and re-supply operations into hostile, denied or politically sensitive areas. The squadron also supports non-combatant evacuation, humanitarian relief, and other special operations.
The second unit is the 67th Special Operations Squadron (Night Owls), which operates the MC-130P Combat Shadow, using night vision goggles to provide long-range, low-level infiltration, exfiltration, and re-supply of special operations forces in hostile or denied territory. The squadron also operates combat search and rescue, medical evacuations, and assists with humanitarian operations. The squadron's aircraft are uniquely capable of providing clandestine air refueling support to special operations helicopters and the new tilt-rotor Boeing-Bell CV-22 Osprey aircraft. There are strong rumours that Mildenhall will eventually take on a unit of the CV-22's, however no one would or could confirm this during our visit. We will have to wait and see.

MC-130H 87-0024 taxying out from the SOG ramp at Mildenhall for an afternoon mission

The Lockheed MC-130H aircraft features terrain-following and terrain-avoidance radars capable of operations as low as 250 feet in adverse weather conditions. The navigation suite includes dual ring-laser gyro's, mission computers and an integrated global positioning system. An extensive electronic warfare suite enables the aircrew to detect and avoid potential threats and if engaged, the system is designed to protect the aircraft from both radar and infrared-guided threats. The MC-130H can also be equipped with aerial refueling pods to provide in-flight refueling of special operations forces and combat search and rescue helicopters. The AN/APQ-170 radar was developed especially for the MC-130H Combat Talon II aircraft. Flight testing of the MC-130H began in September 1988 and the first MC-130H Combat Talon II arrived at Hurlburt Field, Florida on 29th June 1992, and after acceptance testing, began official flying operations on 17th October 1992. In April 1996, MC-130H Talon II aircraft from the 7th Special Operations Squadron based at RAF Mildenhall deployed to Liberia in support of Operation Assured Response. Special Operations troops evacuated more than 2,000 Americans and citizens of other countries from Monrovia following 4 days of intense fighting by rival militias.

An MC-130P "Combat Shadow" taxies back into the SOG ramp at Mildenhall on 18th July 2011
The MC-130P variant of the Hercules primarily flies missions at night to reduce the probability of visual acquisition and intercept by airborne threats. Modifications to the MC-130P feature improved navigation, communications, threat detection and countermeasures systems. The Combat Shadow fleet has a fully-integrated inertial navigation and global positioning system, and night vision goggle compatible interior and exterior lighting. It also has forward looking infrared, radar and missile warning receivers, chaff and flare dispensers, night vision goggle compatible heads-up display, satellite and data-burst communications, as well as in-flight refueling capability, both as a provider or as a receiver. The MC-130P's were previously designated as HC-130N or HC-130P, however the "H" designation is a rescue and recovery mission code and not representative of the aircraft's special operations role. So in February 1996 Air Force Special Operations Command's fleet was redesignated as the MC-130P, aligning the Combat Shadow with other M-series special operations mission aircraft. The aircraft have been part of the special operations mission since the mid-1980s and have provided critical air refueling to Army and Air Force helicopters throughout that time.

Although no aircraft are permanantly assigned to any other units at RAF Mildenhall, the 95th Reconnaissance Squadron frequently operates Boeing RC-135 aircraft from here, providing European and Mediterranean reconnaissance, real-time intelligence, information warfare and combat support to USAFE. The squadron executes missions using the Boeing RC-135 and OC-135 'Open Skies' aircraft. The OC/RC-135's are a variant of the KC-135 Stratotanker, much of the aircraft being filled with electronic equipment in the forward section of the fuselage, whilst the crew positions tend to be in the aft section. As with the KC-135's the aircraft have undergone numerous modifications, including re-engining with the CFM-56 power plants and installation of more modern instrumentation and navigation eqipment in the flight deck. Most TDY aircraft with the unit tend to be the RC-135V or W variants, but often a RC-135S "Cobra Ball" or RC-135U aircraft makes an appearance., along with OC-135's operating Open Skies missions.
The Transient Ramp
As well as the resident aircraft RAF Mildenhall sees a wide variety of transients from the US Air Force, Navy, Marine Corps and Army. It is one of those bases where you can never be quite sure what will turn up next. Probably the most common types are Air Mobility Command (AMC) Lockheed C-5 Galaxy's and Boeing C-17A Globemaster's, both of which are not uncommon sights. However Air National Guard (ANG) and stateside based KC-135R's are also fairly regular visitors, plus of course the ubiquitos C-130 Hercules, of which you could see any variety from Air Force, Navy, Marine and ANG units. The stateside based units are not alone in using Mildenhall as a staging point however, the Turkish Air Force, Saudi Air Force and many other foreign air arms use its available space when needs be, so don't be surprised at anything you may see on a visit. It would be possible to fill a book with the various aircraft transitting through, but below is a very small selection of what can be seen on any given day.

Apart from the regular RC-135 traffic, it's not unusual to see 55th RW OC-135 and WC-135 (above) aircraft at Mildenhall

As we mentioned above, Air Natiional Guard KC-135's regularly use RAF Mildenhall as a staging post on their way to and from the
U.S.A when deploying for Afghan operations. The one above is from the 191st ARS, Utah ANG based in Salt Lake City

With the Special Forces unit being based at RAF Mildenhall it is not surprising that the US-based units use it as a transit point also.
The Lockheed AC-130 'Gunships' are certainly not a common sight, however 2011 seems to have seen rather more than in previous years.

A Brief History of RAF Mildenhall: RAF Mildenhall first opened on 16th October 1934, as one of the RAF's largest bomber stations and received its first squadron and aircraft with the arrival of 99B Squadron, equipped with Handley Page Heyford bombers.
Throughout World War II, Mildenhall remained active, and in addition to its own airfield the base held responsibility for satellite airfields at Newmarket, Tuddenham, and Lakenheath. For the duration of the war, except for a brief period to have concrete runways laid in 1943, RAF Mildenhall was involved in most of RAF Bomber Command's numerous offensives against Germany. The base withstood several attacks by the German Luftwaffe, but was never put out of commission. The bombers from RAF Mildenhall flew their last bombing mission with an attack against Bremen on 22nd April 1945.
Immediately after the war, Mildenhall participated in humanitarian missions, flying home repatriated prisoners of war and dropping relief supplies to the Dutch people stranded by the flooding caused by the retreating German Army. By the end of 1945, Mildenhall operational activity experienced a drastic decrease, and despite a brief flurry of flying activity in the late 1940s, the RAF reduced the base to 'care and maintenance' status.
On 12th July 1950, the 93rd Bomb Group arrived at RAF Mildenhall and began operations. Shortly afterwards the 509th Bomb Wing arrived at Mildenhall, replacing the 93rd Bomb Group. The arrival of the 509th touched off a sequence of transitions, with the 2nd Bomb Wing replacing the 509th in May 1951, followed by the 22nd Bomb Wing replacing the 2nd Bomb Wing later that same year. In October 1951, Strategic Air Command (SAC) took control of the station and bombers rotated in and out of Mildenhall on temporary duty (TDY) assignments from the United States.
From 1954 through to 1958, US politics influenced USAF activities within the United Kingdom, fostering a period of force reduction and modernization. Gradually, the number of Air Force personnel decreased, and SAC departed RAF Mildenhall in late 1958, as its runway no longer met the requirements for its newer aircraft.
In late 1959, RAF Mildenhall became the home for the Military Air Transports Service (later Military Airlift Command) Air Passenger Terminal in the United Kingdom, with the 7513th Air Base Group providing service to the terminal. Late 1965 saw the arrival of the 7120th Airborne Command and Control Squadron (7120 ACCS), previously stationed at Chateauroux Air Station, France, and upon its arrival at Mildenhall, the 7120 ACCS converted from the Douglas C-118 to the Boeing EC-135.
On 8th June 1966 the base received yet another unit, the 513th Troop Carrier Wing (513 TCW), which relocated from Evreaux-Fauville Air Base, France. With its activation on Mildenhall, the 513 TCW assumed operational control of two Military Airlift Command rotational Lockheed C-130 Hercules squadrons and the 7120 ACCS. For the next four years RAF Mildenhall witnessed little change, with only the 10 ACCS replacing the 7120 ACCS, and assuming its mission. However, in the summer of 1972, the base added to the list of its tenants with the arrival of Headquarters Third Air Force, which relocated from South Ruislip Air Station.
The next significant event in Mildenhall history came with the arrival of Detachment 4, 9th Strategic Reconnaissance Wing, which controlled rotational Lockheed SR-71 'Blackbird' and Lockheed U-2R aircraft from the base. Four years after they began rotational duty at Mildenhall, the base became a permanent station for the SR-71 in January 1983, with departure of the last SR-71 on 18th January 1990.
On 18th June 1987, HQ USAFE redesignated the 513 TAW as the 513th Airborne Command and Control Wing (513 ACCW). Nearly five years later, during the Air Force's transition to the objective wing structure, the Air Force inactivated the 513 ACCW and activated the 100th Air Refueling Wing in its place. The activation of the 100th ARW at RAF Mildenhall saw the return of the unit to the country in which it built its war fighting heritage and legacy. Over three years later, RAF Mildenhall welcomed the 352nd Special Operations Group, which transferred from RAF Alconbury in April 1995.
