527th Space Aggressor Squadron

The 527th Space Aggressor Squadron (527 SAS) is a non-flying United States Air Force unit assigned to the 57th Adversary Tactics Group. The 527 SAS is stationed at Schriever Air Force Base, Colorado, being a Geographically Separated Unit (GSU) of the 57 ATG, which is stationed at Nellis AFB, Nevada.

Mission
Its mission is to train US, joint and allied military forces for combat with space-capable adversaries preparing USAF, Joint and Allied Forces for combat through realistic threat replication, training, and feedback through specialized and certified space-capable aggressors. It operates adversary space systems, develops new tactics, techniques and procedures to counter threats, and improves the US military space posture.

The squadron attempts to replicate enemy threats to space-based and space-enabled systems during tests and training exercises. By using Global Positioning System and satellite communications jamming techniques, it provides Air Force, joint and coalition military personnel with an understanding of how to recognize, mitigate, counter and defeat these threats.

The 527 SAS serves to know, teach and replicate a wide array of terrestrial and space threats to the U.S. military's space enablers. The squadron trains the modern warfighter to operate in an environment where critical systems like GPS and SATCOM are interfered with or denied—preparing them for the current and future fights, and guaranteeing U.S. battlefield dominance well into the 21st century.

World War II
Initially activated as an A-20 Havoc dive-bomber squadron in the southeast, trained under Third Air Force. Was realigned to an A-24 Banshee fighter-bomber squadron and re-designated from the 312th to 527th Fighter-Bomber Squadron in August 1943.

Was deployed to Twelfth Air Force in North Africa in May 1943, being initially stationed in Algeria. Flying operations began 15 May from Médiouna Airfield, near Casablanca, French Morocco. Moved eastward supporting the Fifth Army with close air support missions. In the North African Campaign, the squadron engaged German positions in Tunisia

In July, initial elements of the squadron moved to Sicily. From the Gela West airfield, begin flying combat missions, supporting the 1st Division of II Army Corps. On 27 August, the squadron provided air support for the first Allied landings on the European mainland at Salerno, Italy. On 10 September, three days after the invasion of Salerno, advance echelons of the squadron moved to Sele Airfield, near the beachhead. Enemy shelling of the beaches caused considerable difficulty during the move, and the 5527th did not fly its first missions until 15 September.

Moved north through Italy during the Italian Campaign, supported Allied forces by attacking enemy lines of communication, troop concentrations and supply areas. In April 1944 the squadron attacked the German Gustav Line. It also attacked rail and road targets and strafed German troop and supply columns during late spring.

The 527th was an active participant in Operation Strangle, the attempt to cut German supply lines prior to the Allied offensive aimed at rail and road networks, and attacking German troop and supply columns. While Strangle did not significantly cut into German supplies, it did disrupt enemy tactical mobility and was a major factor in the Allies’ eventual breakthrough. During this period the 527th received P-40 Warhawks to augment its aging A-36s, but the obsolescent P-40s were only a stopgap measure. The 527th welcomed its first P-47 Thunderbolts a few weeks later, on 23 June.

Moved to Corsica in July 1944. From Poretta Airfield, the squadron flew bombing missions against coastal defenses in direct support of Operation Dragoon, the Allied invasion of southern France 15 Aug. 1944. Allied forces met little resistance as they moved inland twenty miles in the first twenty-four hours. Once the invasion was completed, the squadron moved back to northern Italy and continued its coastal basing by attacking enemy road and rail networks in northern Italy and, for the first time, flying regular escort missions with heavy bombers. The 527th also conducted armed reconnaissance against the enemy in the Po Valley region.

The 527th continued combat in northern Italy until February 1945, when it left the Mediterranean Theater and moved to Tantonville Airfield (Y-1), France, in the Lorraine region, and operations shifted from targets in the Po Valley to those in southern Germany. The 527th's first mission to Germany – a cause of some excitement – was on 25 Feb. 1945, and by March most missions were flown into Germany against rail lines, roads, supply dumps, enemy installations and airfields. The squadron transferred from Tantonville to Braunshardt Airfield (R-12), near Darmstadt, Germany,

The 527th Fighter Squadron flew its final combat mission on 8 May 1945.

Just after the war, the squadron performed military occupation duty in Germany, with personnel demobilizing throughout the summer. The squadron's last personnel were sent back to the United States from AAF Station Schweinfurt, Germany, on 15 February 1946, with the squadron inactivated as an administrative unit in March.

Cold War
The squadron was reactivated in the postwar era 20 August 1946 at Nordholz Airbase, Germany equipped with surplus P-47 Thunderbolts from storage depots in Europe. Over the next several years, the squadron underwent several redesignations and several station assignments in occupied Germany. In June 1948, the squadron was moved to Neubiberg Air Base, near Munich when tensions with the Soviet Union culminated in the Berlin Blockade. By 1948, it was obvious that the piston-engine Thunderbolts would be no match for Soviet jet fighters, and in early 1950 the squadron was re-equipped with F-84E Thunderjets for air defense of the Munich area

With the arrival of the jet age in Europe, USAFE wanted to move its units west of the Rhine River, as its bases in the Munich area were just a few minutes flying time from Soviet Mig-15 bases in Czechoslovakia. The squadron relocated to a new base, located west of the Rhine River near Kaiserslautern, West Germany in 1952. Landstuhl Air Base opened for operations on 5 August 1952, and the 527th Fighter Bomber Squadron arrived on 21 Aug..

In April 1953, the 527th completed its move to Landstuhl and was soon reequipped with the F-86F Sabre Jet, the first unit in USAFE to fly the most modern American fighter. The F-86F had been very successful as both a fighter and fighter bomber in the Korean War, and marked a quantum increase in the Wing’s capabilities.

A year later the squadron was redesignated the 527th Fighter-Interceptor Squadron and assumed a new mission of air defense for the central European region. For this mission, the squadron was re-equipped with the rocket-armed F-86D Sabre interceptor which provided an all-weather capability

The 527th was inactivated on -8 Feb 1956 due to budget restraints and a reorganization of air defense forces in West Germany by USAFE, with personnel and equipment transferring to the 461st Fighter-Day Squadron.

Aggressor Squadron
In April 1976, the squadron was reactivated at RAF Alconbury, England as the 527th Tactical Fighter Training and Aggressor Squadron, becoming the United States Air Forces in Europe's only aggressor squadron. The 527th began providing aggressor support to European-based combat units in September. Its mission was to train United States Air Forces Europe jet fighter pilots for air combat with Eastern bloc adversaries using "Dissimilar Air Combat Training" (DACT)

The squadron was equipped with the Northrup F-5E Tiger II, being originally part of an order of aircraft destined for South Vietnam. The first batch of eight aircraft were air-freighted into Alconbury on 21 May 1976 on board a Lockheed C-5A Galaxy direct from the production facility at Palmdale, California. Eight more Tigers arrived on 14 June with the final batch of four following ten days later, on 24 June. These aircraft were also airfreighted on board a C-5A. The 527th was fully operational a few months later with the first DACT course commencing in October 1976

The aggressor F-5Es were painted in a variety of colourful camouflage schemes designed to mimic those in use by Warsaw Pact aircraft. Two-digit Soviet-style nose codes were applied to most aggressor aircraft. These coincided with the last two digits of the serial number. When there was duplication, three digits were used.

International conventions made it necessary for military aircraft to carry their national insignia, but the star-and-bar national insignia was reduced in size and relocated to a less-conspicuous position on the rear fuselage. The 527th's Aggressor aircraft were among the first to apply the star and bar in toned-down or stencil form, now standard on USAF aircraft.

The 527th Aggressors flew their aircraft in intense turns and other maneuvers as their mission involved intense combat fighter training, often involving high-G turns at supersonic speeds. The Aggressors trained both United States Air Force squadrons in Soviet fighter tactics, but deployed frequently to other NATO airfields, training pilots from Norway to Greece and Turkey, France, West Germany and the Low Countries in combat tactics.

After 12 years of intense flying, in 1988 the fleet of aggressor F-5Es were getting rather worn out as a result of sustained exposure to the rigours of air combat manoeuvring. There were restrictions placed on operations in which pilots were warned not to exceed a certain G-load. Some repair kits had to be devised to overcome these problems, and the estimated cost of repair of the entire fleet was beginning to exceed a billion dollars. In addition, with the appearance of a new generation of Soviet fighters, it became apparent that F-5Es could no longer adequately mimic Warsaw Pact threats.

It was decided to re-equip the squadron with F-16C Fighting Falcons and reassign the squadron to RAF Bentwaters. In return, the A-10's at Bentwaters would be reassigned to Alconbury and give the 10th a new Close Air Support (CAS) mission.

After the 527th was reassigned, eight of the lowest-hour F-5E's were transferred to the U.S. Navy for TOPGUN/Aggressor training at NAS Miramar, California in July 1988. The remainder were sent to storage at RAF Kemble for refurbishing. From there they were sold under the foreign military assistance program to Morocco and Tunisia in October 1989. One F-5E was thought to be retained at Alconbury for static display as a gate guard. In reality this is a plastic/fiberglass model with an authentic windscreen and canopy.

The 527th AS flew its last F-5E sortie from Alconbury on 22 June 1988 and personnel and equipment was moved to RAF Bentwaters. The first two of an intended complement of eighteen F-16Cs arrived at Bentwaters on 14 June 1988. These were single examples taken from the 52d Tactical Fighter Wing at Spangdahlem AB, West Germany and the 86th Tactical Fighter Wing at Ramstein AB. The squadron was officially activated on 1 July 1988, with the first four months dedicated to pilot conversion for the new aircraft.

The 527th AS resumed their aggressor role in November 1988 when six McDonnell Douglas F-15C Eagles from the 36th TFW at Bitburg AB, Germany arrived at Bentwaters for the start of a three-week DACT course. The 527th's complement of aircraft had reached twelve on 16 January 1989 when one more F-16C was delivered from Spangdahlem AB.

However, in 1989 with the collapse of the Warsaw Pact and a reduction of defense spending, the decision was made to terminate the entire USAF aggressor program. In November 1989 the 527th AS began disposing of its F-16Cs in preparation for inactivation the following year. The first two aircraft to leave were flown to Spangdahlem AB on 29 November 1989. The 527th AS had reassigned its entire fleet of 12 aircraft by mid-1990 and was inactivated on 30 September 1990. It was to be the only F-16 unit ever to be based in the United Kingdom.

Modern era
The 527th was not activated again until 29 September 2000 when it became the 527th Space Aggressor Squadron. On 14 April 2006 the squadron moved from under Air Force Space Command to Air Combat Command. The unit now reports to the 57th Adversary Tactics Group of the 57th Wing.
