509th Weapons Squadron

The 509th Weapons Squadron is a United States Air Force unit. It is assigned to the USAF Weapons School at Fairchild Air Force Base, Washington. The squadron is a geographically separated unit of the 57th Wing at Nellis Air Force Base, Nevada.

The squadron's first predecessor is the 609th Bombardment Squadron, which served as a heavy bomber training unit during World War II until it was disbanded in a general reorganization of Army Air Forces training and support units in the United States in 1944. The second predecessor is the 509th Air Refueling Squadron, which was one of the first refueling units in the Air Force and deployed planes and Aircrews to support strike forces in the Vietnam War and during Desert Storm.

Mission

The mission of the squadron is to provide Boeing KC-135 Stratotanker instructional flying.

History

World War II

The squadron was first activated as the 609th Bombardment Squadron, one of the four original squadrons of the 400th Bombardment Group, at Pyote Army Air Base, Texas, in March 1943. The group was equipped with Consolidated B-24 Liberators and served under Second Air Force as an Operational Training Unit (OTU) at several bases in the southwestern United States until the end of the year.Maurer, ''Combat Units'', p. 285 The OTU program involved the use of an oversized parent unit to provide cadres to "satellite groups".Craven, & Cate, Vol. VI, Men & Planes. p. xxxvi

The unit moved to Charleston Army Air Field, South Carolina in late December, where it became part of First Air Force and changed its mission to that of a Replacement Training Unit (RTU). RTUs units were likewise oversize units, but their mission was to train aircrews prior to their deployment to combat theaters. However, the Army Air Forces found that standard military units, based on relatively inflexible tables of organization, were proving less well adapted to the training mission. Accordingly, it adopted a more functional system in which each base was organized into a separate numbered unit. while the groups and squadrons acting as RTUs were disbanded or inactivated. This resulted in the 609th, along with other units at Charleston, being disbanded in April 1944 and being replaced by the 113th AAF Base Unit (Bombardment (Heavy)), which assumed the squadron's mission, personnel, and equipment.

Cold War

The 509th Air Refueling Squadron was activated at Roswell Air Force Base, New Mexico and assigned to the 509th Bombardment Group. The squadron was one of two air refueling units in the United States Air Force, activated on 12 July 1948. The 509th Air Refueling Squadron and 43rd Air Refueling Squadron were the first Air Refueling Squadrons in the Air Force. The squadron initially equipped with Boeing KB-29M Superfortress tankers. These aircraft carried a system of hoses, reels, winches and fuel pumps to transfer fuel to the receiver aircraft. A power-driven reel for the refueling hose was installed in the rear fuselage at the position where the lower aft turret had been located prior to its removal. The KB-29M also had a cable and associated winch (known as the contact line) that was used to assist in the setup of the connection between the two aircraft.

Although the hose refueling system proved to be feasible, in practice the system had the disadvantage in taking a long time to make the contact and engage the hoses. Once contact was made, the rate of fuel transfer was slow, and the hoses provided a lot of aerodynamic drag which limited the airspeed. Consequently, the hose system was used for only a few years before it was replaced by the Boeing-developed flying boom system installed on the KB-29L. While flying the KB-29 the squadron deployed to RAF Upper Heyford, England from June to September 1952.

In 1954, the squadron converted to the Boeing KC-97 Stratofreighter, deploying once again to the United Kingdom with the KC-97 for most of the first four months of 1956, this time to RAF Lakenheath. The squadron moved to Pease Air Force Base, New Hampshire in January 1958, but was not joined there by the rest of the 509th Bombardment Wing until July. The squadron was inactivated in 1965 as the 509th phased down in preparation for inactivation.Although the decision to inactivate the wing was reversed and it instead converted from B-47s to B-52s, a new KC-135 squadron became the wing's refueling element. Ravenstein, pp. 276–277

The squadron was activated again in June 1966, with Boeing KC-135 Stratotankers, when the 509th wing expanded its refueling capability by adding a second squadron of tankers to those of the 34th Air Refueling Squadron at Pease. It continued to fly the KC-135 until inactivated in 1994 at Griffis AFB, New York.''See'' Mueller, p. 470

Weapons training

The squadron was reactivated in 1999 at Fairchild Air Force Base initially as the KC-135 Combat Employment School in Air Mobility Command's Air Mobility Warfare Center based at McGuire Air Force Base, New Jersey. Its first student class began in June 2000. In 2006, the Air Force consolidated all weapons squadrons under the United States Air Force Weapons School under the 57th Wing at Nellis Air Force Base, Nevada. In six months of training, weapons upgrade students receive graduate-level training in air refueling core competencies and learn to integrate and plan for joint operations. The students went to Nellis three times to receive "core" classes with the rest of the weapons school. They deployed on temporary duty assignments for terminal approach tactics at Roswell, New Mexico, participated in United States Strategic Command integration at Offutt Air Force Base, Nebraska, certify in special operations air refueling at Hurlburt Field, Florida and exercise with Northrop Grumman B-2 Spirits at Whiteman Air Force Base, Missouri, and plan and execute a mission employment exercise from Nellis two weeks before graduation.
