The 7499th Support Group is an inactive United States Air Force organization. Its last assignment was with the United States Air Forces in Europe, being stationed at Weisbaden Air Base, West Germany. It was inactivated on 30 June 1974. It's mission was resumed by the 7575th Operations Group, which operated from Rhein-Main Air Base, West Germany from 1 July 1977 until its inactivation on 31 March 1991

History

The 7499th participated in overt and covert reconnaissance throughout the European theater during the Cold War and reported directly to Headquarters USAFE. The unit was initially formed as a squadron in 1948, first at Furstenfeldbruck AB, West Germany. By 1955, with the pending inactivation of the Military Air Transport Service Air Resupply And Communications Service organization at RAF Molesworth, England, the unit was expanded to a group level and moved to Wiesbaden AB.

Origins

The unit's origins begin on 9 August 1946, when a Army Air Forces C-47 Skytrain departed Tulln Air Base near Vienna, Austria, on a scheduled courier run that would take it to Venice, Italy, then south to Rome. These flights were routine, and this aircraft had three passengers besides the crew and cargo. As the C-47 flew toward Venice, it encountered heavy weather, including an undercast, and, unknown to its crew, blundered into Yugoslav airspace for several minutes. Before long Yugoslav Yak-3 fighters came on the scene and shot the C-47 down. The pilot skillfully crash-landed and all the people aboard survived but were interned. This caused an immediate uproar from the US government, and stern statements were issued to Yugoslav Prime Minister Tito about immediate release and access to the crash site. Talks were underway when, on 19 August, incredibly, almost the same exact event occurred again. Another C-47 courier aircraft was shot down by Yugoslav fighters in the same area. This time the crew was not so fortunate and all aboard perished.

Under threat of US cutoff of aid to Yugoslavia, Tito yielded, the interned Americans were released, and some compensation paid to the next-of-kin of the dead personnel. Relative calm ensued between the US and Yugoslavia, but a question lingered in the minds of officials in USAFE Headquarters at Wiesbaden AB, Germany. How did those Yugoslav fighters, twice, find those C-47s in bad weather and shoot them down?

USAFE acquired an RB-17 Flying Fortress from a photo-mapping unit, Detachment A of the 10th Reconnaissance Group at Fürth Airfield, Germany. These aircraft were in Europe as part of Project Casey Jones, an attempt to photomap as much of the world as possible to create maps and charts for use in future contingencies, and installed Electronic Countermeasures equipment in it. The B-17 was flown carefully along the border near where the C-47s had been shot down, making sure it did not infringe Yugoslav airspace. By luck, on the very first mission, the Yugoslavs cooperated and turned on their radar and began tracking it. The equipment picked up the familiar signals from a German Würzburg radar on about 560 MHz and took bearings, dozens of them, all of which cut at the same point. Where the bearings crossed there had been a German radar school during the war. Obviously the Yugoslavs had put into service one or more of the old German radars.

This mission was so successful that USAFE directed that further electronic "ferret" missions be flown along the border with the Soviet zones of Germany and Austria, as well as over the Baltic Sea, looking for Soviet radar stations. Over the next several years these aircraft detected a gradual Soviet radar buildup in their zones. During the Berlin Airlift 1948-49, the B-17s would fly occasional missions in the Berlin Air Corridor, using call signs making them appear as airlift C-54s (“Big Willie”). They flew only at night and did not land at Tempelhof airfield, declaring emergencies with “landing gear problems” and thus exiting to the west without Soviet observers seeing them.

Thus began the ELINT mission. Detachment A would go on to join a flight of the 45th Reconnaissance Squadron (specializing in photo recon) on 26 March 1947 and move to Fürstenfeldbruck Air Base, Germany. Then came the Berlin Airlift, in June 1948. As part of the collection operation some C-47s and RB-26 Invaders were acquired and modified with cameras. They occasionally flew as part of the airlift stream, diligently collecting photography. A few B-17 ELINT flights were also made in the Berlin Air Corridors, but only at night.

Most likely because of the Airlift and its accompanying sharp increase in tensions, USAFE decided to form the reconnaissance and ELINT units into a single squadron. The 7499th Air Force Squadron was activated at Fürstenfeldbruck on 1 November 1948.

7499th Support Squadron

EC-97G Stratofreighter 52-2688

From Fürstenfeldbruck, the 7499th continued to fly frequent missions in the West Berlin Air Corridors. As the Soviets modernised their units and increased their presence, it was vital to gain as much information on them as possible. For better management of this covert outfit as well as to bring it closer to the major USAFE photo and ELINT interpretation centres, the 7499th moved in August 1950 to Wiesbaden AB, within a few miles of USAFE Headquarters.

Beginning in 1950, the unit upgraded to C-54 Skymasters to do both photo reconnaissance and ELINT work, replacing the B-17s. The C-54 boasted better collection capability, and had the additional advantage of actually being a transport, thus attracting much less attention at Tempelhof. C-47s also replaced the RB-26s, the C-47s also being less visible to the Soviets than the Invader bomber overflying East Germany.

In addition, a new aircraft, a specially­ modified Boeing EC-97G Stratofreighter, made its appearance in 1953. This aircraft (serial 49-2952), covertly carrying a 240 inch focal length camera, was codenamed PIE FACE and was mostly used along the periphery of the satellite nations. But an occasional West Berlin Air Corridor mission, even at the required altitudes of less than 1O,000 ft, would produce spectacular, high-resolution photography, very useful for technical analysis of equipment. This aircraft would provide valuable imagery right up until 1962, when it was finally relegated to the scrapheap after some productive missions around Cuba during the Cuban Missile Crisis.

7499th Support Group

In 1955, in response to increasing collection requirements and the pending inactivation of the MATS intelligence units, USAFE upgraded its reconnaissance effort, creating the 7499th Support Group at Wiesbaden with three squadrons.

7405th Support Squadron

The former 7499th Squadron became the 7405th Support Squadron, remaining at Wiesbaden as the only unit to conduct corridor collection. Its C-47s and RB-26s soldiered on into the late 1950s, and some C-54s until 1963, but another generation was about to arrive.

The 7405th had been openly tasked with the courier mission to West Berlin, meaning it was to conduct daily flights to and from Tempelhof Air Base carrying passengers and priority cargo. It was known as the "Berlin for Lunch Bunch". Under this cover the newer aircraft were to continue their collection using better sensors, including the first infrared imagery sensors. In 1959 the C-47s were supplanted by four Convair T-29s, navigator trainers converted for courier work and vertical photography.

Two additional Boeing EC-97Gs that arrived in 1963 were ostensibly cargo carriers, but fitted with oblique cameras and, in one case, with ELINT gear. These aircraft were designed to gather high-quality technical data on the then-new Soviet SA-2 Guideline Surface-to-air missile system, which by the mid-1960s had spread throughout the Warsaw Pact countries, especially in East Germany, and was downing US aircraft over North Vietnam. This platform was especially valuable for providing data enabling the US to design appropriate electronic countermeasures against the SA-2. The north and south West Berlin Air Corridors were unique places for this collection, since several Soviet SA-2 sites were located directly within corridor limits. When the SA-2 was superseded by more advanced missile systems, the aircraft was reconfigured to collect on them.

7406th Support Squadron

Lockheed C-130A-LM Hercules, AF Serial No. 54-1637 of the 7406th Operations Squadron.

The 7406th Support Squadron was activated at Rhein-Main Air Base, West Germany on 10 May 1955 and received its first aircraft (RB-50E Superfortress) in March 1956. The mission of the 7406th SS was airborne reconnaissance. The 7406th SS owned and maintained the aircraft and provided the flight crews. A separate USAF Security Service squadron provided the recon crew that manned the intelligence collection positions on the aircraft.

The RB-50s were replaced with specially configured C-130A-II Hercules recon aircraft in 1958. The first C-130A Hercules 56-0484 was assigned in March 1958. Other C-130A-II aircraft assigned to the 7406th SS included in order of assignment from July to October 1958: 56-0525, 56-0528, 56-0530, 56-0534, 56-0538,56-0541, 56-0535 and 56-0540.

One of these C-130's (60-528) was shot down with the loss of a crew of seventeen (six 7406th flight crew members and eleven USAFSS recon flyers) over Soviet Armenia on Sept 2, 1958, becoming the first C-130 lost to hostile fire. Four Soviet MiG-17 pilots took turns firing on the unarmed C-130 when the American aircraft inadvertently penetrated Soviet airspace while on a recon mission along the Turkish-Armenian border. C-130 60-528 had less than 200 flying hours when it was shot down.

The 7499th operated temporarily out of Macdill AFB, Florida in the 1960s. At first (Feb 1964) it was under the 15th Tactical Fighter Wing (TAC), then in Feb 1966 the 4409th Support Squadron was set up. The mission area was the north coast of Cuba with a coordinated U-2 mission. At first 7406th flight crews, on TDY, trained TAC & 4409th flight crews. As more 7406th personel transferred to the 4409th the TDY training stopped.

C-130B-II Hercules aircraft that had previously been assigned at Yokota Air Base, Japan from 1961-1971 were sent to the 7406th at Rhein-Main AB in 1971, replacing the C-130A-II models that were converted to original 'cargo' configuration and assigned to Air National Guard units in CONUS.

The 7406th SS continued flying reconnaissance missions from Rhein-Main in the C-130B models until June 30th 1973 when the squadron's sister Security Service flying squadron moved to Hellenikon Air Base, Athens, Greece. as Det #1, 7499th Support Group. The 7406th had two hotels in Glifada with two to a room. This was just south of Athens and Hellenikon and across the road from a beautiful beach. Uniforms were not permitted off base. The 7406th SS operations remained at Rhein-Main but flew its operational missions out of Hellenikon from 1 July 1973 until its last C-130B-II mission was flown on June 13, 1974. The unit was flying only Mediterranean missions by this time. The 7406th SS was deactivated on 30 June 1974. After deactivation of the 7406th Squadron the 55th Strategic Reconnaissance Wing (SAC) at Offutt AFB, Nebraska took over the missions with Boeing RC-135 aircraft.

On Sept 2, 1997, the National Security Agency (NSA) dedicated at National Vigilance Park, Fort Meade, Maryland an Aerial Reconnaissance Memorial consisting of a refurbished C-130A tail number 57-0453 that has been restored to look identical to C-130A 60-528 when it was shot down. The Aerial Reconnaissance Memorial honors all SILENT WARRIORS (all military airborne recon crews) who paid the ultimate price while defending their country.

7407th Support Squadron

The 7407th Support Squadron performed airborne photo surveillance. They used RB-57A, then RB-57D, and finally RB-57F Canberra aircraft at Rhein-Main AB. Initially operating the RB-57A, capable of carrying P-2s, K-17s, K-37s, K-38s, or T-17s cameras in the bomb bay which could be interchanged according to the aircraft's mission. The intended mission included day and night, high and low, and visual and photographic reconnaissance. The RB-57A was totally unarmed. It was painted with a high gloss black paint which was intended to minimize detection by searchlights. The crew was two--one pilot and one photo-navigator.

The service of he RB-57As was brief, as in 1957, midair-refuelling capable RB-57D Canberras were deployed in 1957 to the 7407th CSS to support USAFE operations. All RB-57D operations were under heavy security and very little information ever leaked out about their early operations. They presumably carried out reconnaissance missions along the East German border and over the Baltic Sea. Since the missions were carried out under an atmosphere of high secrecy, RB-57s returning from missions over the Baltic were often intercepted by RAF Hawker Hunters just to make sure that they were not Soviet aircraft.

Martin/General Dynamics RB-57F-CF 63-13291, 7407th Combat Support Squadron, Rhein-Main AB, West Germany. Aircraft retired to AMARC as BM0106, 30 May 1974.

This squadron had a Detachment 1 organized at Bitburg Air Base, West Germany using three RF-100A Super Sabre reconnaissance aircraft (53-1551, 53-1554, 53-1554) known as "Slick Chicks". In May 1955, after successful competition of flight tests, the aircraft were sent to the 7407th Support Squadron.

The over-flight operations these aircraft conducted are still classified, however, one details of one particular flight in October 1956 have leaked out. On this sortie the pilot of 53-1551 took off from a base in Turkey to photograph a rocket base deep inside the Soviet Union. The RF-100A was quickly picked up by Soviet radar and, as the target was at the extreme range of the aircraft, the pilot had no option but to fly a virtually straight track. As a consequence the Soviets soon determined the intended target. Throughout the mission, the pilot was faced with the unnerving spectacle of a never-ending stream of Soviet interceptor fighters attempting to bring down the RF-100A by firing a variety of machine-guns, cannons and missiles at the aircraft.

To compound the pilots problems, his heavy fuel load and four drop tanks allowed only very limited evasive manoeuvring. Thanks to poor Soviet gunnery, inadequate planning by the Soviet Fighter Controllers and a fair slice of luck, the pilot reached the target and took the required photographs. However, his problems were far from over, as the target was at the extreme limits of the aircraft’s range and no other airfields were available, he had no choice but to reverse course and retrace his route. The pilot made it back to Turkey, but with virtually empty tanks having kept the aircraft in continuous afterburner for over half an hour as he shot past some extremely agitated Russians – as the RF-100A was officially limited to just a few minutes of afterburner, this effectively destroyed the entire aft fuselage.

As far as it can be established, none of the "Slick Chicks" were lost over unfriendly territory. In June 1958 the Detachment was inactivated and the two remaining RF-100A’s were transferred to the 3131st Maintenance Group at Châteauroux-Déols AB, France and eventually were sent to Taiwan.

Intelligence gathering sorties by the RB-57D's continued until 1964 when wing fatigue problems caused type to be withdrawn from service. In late 1963, the first two Martin RB-57F Canberras went for operational trials with the 7407th CSS They carried out a series of high-altitude reconnaissance flights along the East German border and over the Baltic Sea. In February 1964, following these trials, they were transferred to the 58th Weather Reconnaissance Squadron at Kirtland AFB, New Mexico. Eventually two RB-57Fs were assigned to the 7407th CSS in 1964.

On 14 December 1965, one of the RB-57Fs (63-13287) operating out of Rhein-Main AB was lost during a mission over the Black Sea. What actually happened is still uncertain. There were reports that the aircraft had been shot down by a Soviet S-75 Dvina Surface-to-air missile, but at the time, the official statement by the USAF was that the aircraft crew had probably perished from an oxygen system failure, since it took over an hour for the aircraft to spiral down from altitude and fall into the Black Sea. Although seven or eight days were spent searching for the wreckage, only small bits and pieces of it were ever found. However, there were also reports that the two crewmembers were captured alive by the Soviets, with their ultimate fate being uncertain.

Stress cracks began appearing in the wing spars and ribs of the RB-57Fs in the early 1970s and the activities of the RB-57Fs were restricted. The last of the RB-57Fs were retired in early 1974 and 7407th squadron was inactivated 30 June 1974.

Downsizing

All along, the 7405th and its sister squadrons were also flying peripheral reconnaissance missions throughout Europe and, increasingly, the Middle East, but beginning in the late 1960s Strategic Air Command Boeing RC-135s assumed a greater share of the peripheral strategic reconnaissance mission and on 30 June 1974 the 7499th Group and 7406th and 7407th squadrons were inactivated. The 7405th Support Squadron was re designated as the 7405th Operations Squadron and continued its mission.

7575th Operations Group

Lockheed C-130E-LM Hercules 62-1828. The Aircraft fitted with various sensors and used by the 7405th Operations Sqdn as spyplane operating from Frankfurt/Rhein-Main AB, West Germany. 1828 is shown landing at Tempelhof Cemtral Airport, West Berlin, on 14 April 1981. Note the fake MAC markings (the 7405th was subordinate to USAFE), probably designed to enable these C-130Es to blend in at the 7405th's Rhein-Main base.

However, the West Berlin Air Corridor missions were unique and no RC-135s would be flying to West Berlin. So the 7405th Support Squadron and its "Berlin for Lunch Bunch" C-130s continued this unique task, the squadron being directly assigned to HQ USAFE.

In late December 1975, the 7405th flew its last EC-97G mission from Wiesbaden Air Base when the USAF turned the base over to the United States Army and moved its operations to Rhein-Main AB. There, re-designated as the 7405th Operations Squadron, it acquired three heavily-modified C-130E Hercules, airlifters in name only. By this time, technology improvements were such that each aircraft could carry a variety of sensors with advanced capabilities. Thus, if one sensor type detected a new and unusual activity, the aircrew could almost instantly bring other sensors to bear on it. This ability provided lucrative intelligence time and time again.

On 1 July 1977, the squadron was assigned to the newly organized 7575th Operations Group at Rhein-Main AB. Along with the 7575th OG, the 7580th Operations Squadron was activated on 1 July 1977 at Rhein-Main AB. The 7580th OS was a non-flying squadron staffed with C-130 Electronic Warfare Officers (EWOs) and aircraft maintenance personnel.

The 7405th's corridor/Control Zone collection missions, with their pivot at Tempelhof Central Airport, continued through the 1980s. Then came the 1989 collapse of the Warsaw Pact and the fall of the Berlin Wall; the 1990 German reunification, and the phase-out of Soviet armed forces from Eastern Europe. The 7405th helped monitor this until shortly before Germany was reunified. On 27 September 1990, the last C-130 collection mission was flown; then, on 3 October, the Berlin Air Corridors and Control Zone officially disappeared. From 1946 to 1990 the "Berlin for Lunch Bunch" had flown over 10,000 missions to West Berlin. Now it had flown its last, Germany and the city of Berlin were again unified, and the 7405th Operations Squadron faded into military aviation and intelligence history. It's mission was completed.

The 7405th Operations Squadron was inactivated on 1 January 1991; the 7575th Operations Group and 7580th Operations Squadron were inactivated on 31 March 1991.
