Brooks Air Force Base is a closed United States Air Force facility, located in San Antonio, Texas. It was closed on 30 September 2011.

In 2002 Brooks Air Force Base was renamed Brooks City-Base when the property was conveyed to the Brooks Development Authority as part of a unique project between local, state, and federal government. The Brooks Development Authority is now the owner and operator of the property, and is redeveloping it as a science, business, and technology center. The Air Force was the largest tenant at Brooks City-Base.

Brooks Air Force Base was one of thirty-two Air Service, United States Army training camps established in 1918 after the United States entry into World War I, being established on 8 December 1917 as Kelly Field No. 5.[1] Flying at Brooks, however predates its military establishment, as the facility was known as Gosport Field prior to the first Army airplanes arriving on 5 December 1917.[2][3]

Brooks Air Force Base was named to honor San Antonio aviator Sidney Johnson Brooks, Jr.[4] Cadet Brooks died on 13 November 1917 when his Curtiss JN-4 nosed down as he prepared to land after a training flight at Kelly Field, TX. Brooks was one of the first to volunteer at the call for men for the American Flying Corps; he was in training for a commission as a military aviator.[5] He was awarded his wings and commission posthumously.

World War I

The history of Brooks Air Force Base parallels the history of military aviation and aviation medicine in the United States. After the United States entered World War I, in April 1917, the U.S. Army recognized the need for trained flying instructors. San Antonio was chosen for a year-round training site due to its favorable climate, good water supply and convenient transportation facilities.[6]

The Chamber of Commerce assembled an 873-acre tract southeast of the city near Berg's Mill and offered it as the site for the new aviation field. The site was originally called Gosport Field, a name derived from the flight instruction system used at the new base. On 5 December 1917, the Army named the site Kelly Field No. 5, and on 8 December, ground breaking ceremonies were held.[6]

On 16 February 1918 Kelly Field No. 5 became a separate post and named Brooks Field by the Aviation Section, U.S. Signal Corps The first commander of Brooks Field was Lt. Col. H. Conger Pratt, who until the preceding October had been a cavalryman.

The first aircraft flown from the new Brooks Field 28 March 1918, was a Curtiss JN-4D "Jenny" of World War I fame, piloted by Maj. Leo A. Walton. Brooks Field, contained the principal flight instructor's school. Brooks Field was used as the Air Service Flight Instructor's School. It was a six-week course, with a maximum student capacity of 300.[7][8]

During its first year of operation, Brooks Field consisted of 16 hangars with extensive support facilities. Of these early buildings, Hangar 9, now the Edward H. White, II Memorial, is the only structure still in existence.[6]

Inter-war years

In May 1919, the pilot instructor school was closed and a Balloon and Airship School was opened for pilots and ground crew members. A huge 91,000-square-foot airship hangar was constructed.

Balloon units assigned
  • 67th Balloon Company, May–June 1919[9]
  • 72d Balloon Company, May–June 1919[9]
  • 93d to 99th Balloon Company, May–June 1919[9]
Consolidated into the Air Corps Balloon and Airship School, Brooks Field, June 1919

However, a series of mishaps in operating the hydrogen-filled craft led to the transfer of the school from Brooks to Scott Field, Illinois on 26 June 1922.[6] After the cancellation of the airship training, the 11th School Group was formed at Brooks Field as the Primary Flying School for the Air Service and Army Air Corps, replacing the World War I school at Carlstrom Field, Florida.[10]

Brooks Field, Texas, JN-6s, 1925

The Primary Flying School operated between September 1922 through July 1931. The school took about six months initially, with advanced training later divided into three months each of basic and advanced instruction. The dual trainer initially used was the Curtiss JN-6H. Brooks later accepted other planes, including Vought VE-7 Bluebirds and Dayton-Wright TA-3s, for evaluation, but JNs were used until 1926. The beginning class in March of that year was the first without Jennies. Students now flew in the new Consolidated PT-1, with tandem seats and a Wright E engine.[10] A few National Guard officers went to Brooks Field in January 1923 for pilot instruction. World War I flyers underwent refresher training while others took the regular course. Eight of the ten officers entering graduated to become junior airplane pilots. The Air Service suggested, and the Militia Bureau adopted, a policy of giving men flying training before commissioning them in the Guard.[10] During the 1920s, the Primary Flying School at Brooks expanded but still could not accommodate all primary students. Needing another school, the Air Corps reopened March Field, California.[10]

Reorganizing pilot training, the Air Corps created a Training Center at San Antonio with Brig. Gen. Frank P. Lahm in charge. He opened headquarters at Duncan Field on 1 September 1926. As an Assistant Chief of Air Corps, he commanded the Primary Flying School and the School of Aviation Medicine (Flight Surgeons) at Brooks Field, and the Advanced Flying School at Kelly Field.[10] In 1927 basic moved out of the advanced phase and combined with primary. At that point, primary-basic changed to eight months in length and advanced to four months. With the beginning of the five-year expansion program.[7] More than 1,400 pilots were trained during those years and graduates included such notable aviation figures as Generals Claire L. Chennault, Thomas D. White, Nathan F. Twining, and Col. Charles A. Lindbergh.[6]

Also during this period, the School of Aviation Medicine was moved from Randolph Field in October 1931.[6]

Brooks Field, 1939

On 28 September 1929, Brooks was the site for the first successful mass parachute drop in the world. The concept, conceived and implemented at Brooks, confirmed the practicality of tactical paratrooper warfare. The concept proved its value during World War II.[6]

During the 1930s, Brooks was the center of aerial observation activity and several units were trained in tactical observation. In 1938, the Air Corps wanted to move Headquarters 21st Balloon Group to Brooks Field to organize a balloon school. Ten years had passed since it had trained observers at Scott Field. It needed 300 more observers for balloon units in mobilization plans. It wanted to run 2 sessions a year at Brooks, with 5 officers of the Regular Army and 15 from the National Guard in each class. The War Department thought the proposal significant enough to merit further study. On 21 September 1938, the small band of lighter-than-air enthusiasts in the Air Corps lost their leader (General Westover) in an aircraft crash. Instead of letting the Air Corps open a school, the War Department inactivated the 21st Balloon Group at Scott Field on 1 June 1939. Thus, the lighter-than-air branch consisted of 3 balloon squadrons, plus 10 officers and 350 enlisted men, when war broke out in Europe.[10] In 1940, Brooks became the site for a special school for combat observers.[6]

World War II

During World War II, Brooks Field housed the School for Combat Observers and the Advanced Flying School (Observation). To cope with the huge buildup in personnel and equipment, the Air Corps adopted a policy of using temporary construction for housing and permanent structures for technical buildings, putting up tents to accommodate personnel.[10]

The program remained in operation until 1943 when it was disbanded. Training in the school then switched to twin-engine aircraft, flying the Curtiss AT-9 "Jeep," the all-wood Beechcraft AT-10 Wichita, or the Cessna AT-17 Bobcat, subsequently training pilots to fly the B-25 Mitchell bomber beginning in 1943 until the end of the war.[6]

Cold War

Reserve Training Center

Hangar 9 stands as the only World War I era aircraft hangar listed in the National Register of Historic Places. Hangar 9 was built as a "temporary" structure in 1918 when Brooks Field was established as the location for the Signal Corps Aviation School.

When pilot training at Brooks Field concluded at the end of World War II, the base took on a new mission. In September 1951 in the midst of the Korean War, the Air Force established a reserve training center at Brooks Air Force Base. The 907th Air Reserve Wing was assigned to the center. Conceived originally as a troop carrier unit, the wing did not receive its first planes until the summer of 1952. The planes were T-6 Texans, an indication of the 907th's new mission, Air Force Reserve pilot training.[6]

Almost before it began its new mission, the 907th Air Reserve Wing was replaced by the 8707th Pilot Training Wing (Single-Engine). On the first anniversary of its activation, the 8707th had six T-6s and two C-46 Commandoes assigned. That began to change in April 1953 when the wing acquired its first five North American T-28 Trojans.[6]

In 1954 Colonel David L. "Tex" Hill, a fighter pilot who made his reputation as a member of Chennault's Flying Tigers, took over the wing's pilot training program. At year's end the wing converted to C-46s and the 8707th was replaced by the 433d Troop Carrier Wing.[6]

In 1956 reservists celebrated their fifth anniversary at Brooks with the arrival of another aircraft, the C-119 Flying Boxcar transport. Four years later, the 433d Troop Carrier Wing moved to Kelly AFB. From the time the Reserve first established a wing at Brooks in 1951, whatever the numerical designation, the people of San Antonio have always referred to the unit as the Alamo Wing.[6]

An era in aviation history ended on 20 June 1960, when the last plane took off from Brooks. The aircraft was a C-131 Samaritan piloted by Col. L.B. Matthews, commander of Det. 1, 1st Aeromedical Transport Group.

Aerospace Medicine

During the late 1950s, Brooks was transformed from a flying training center to a center for modern medical research and development and education center. The transition started in the summer of 1959 when the School of Aviation Medicine returned to Brooks from Randolph AFB. Brooks became the headquarters for the school of Aerospace Medicine (SAM).[6] In 1957, SAM scientists moved into the newly completed center at Brooks AFB. SAM aided the National Aeronautics and Space Administration (NASA) with Project Mercury and served as a back-up site for lunar samples brought back to Earth on the Apollo missions between 1969–1972. The air evacuation program at Brooks AFB proved vital to the care of wounded personnel in the Vietnam War.

Brooks Field Hangar 9 was restored in 1969 to become the U.S. Air Force Museum of Aerospace Medicine. This museum is to display the early history of Brooks Field and to preserve and display an extensive collection of photographs and equipment related to aviation and aerospace medicine.[14][15]

Historic Hangar 9

In 2012, the $90 million Mission Trail Baptist Hospital opened;[12] in 2014, the University of the Incarnate Word announced plans to build a medical school on 26 acres, the first phase of which is scheduled to open in 2016.[13]

In 2005, Brooks City-Base was once again placed on the BRAC list. Air Force operations ceased on Sep. 15, 2011. The Brooks Development Authority has demonstrated economic development success with projects including a 62-acre (250,000 m2) retail development, approximately 256,000 square feet (23,800 m2) of research and distribution facilities for DPT Laboratories, the South Texas Center for Emerging Infectious Diseases (an infectious disease research institute coordinated with the University of Texas at San Antonio), an international pharmaceutical company, and a $25.5 million City/County emergency operations center which opened in the Fall 2007. The 311th Air Base Group inactivated on Sep. 1, 2011, and the remaining few USAF personnel had shuttered the base for good by the 15th of that month.

Following the 1995 BRAC, when Brooks AFB was removed from the Base Realignment and Closure list, city, state, military, and community planners began several years of hard work to develop a plan to privatize approved the gradual transition in ownership of Brooks AFB from the Air Force to the Brooks Development Authority. This transition came into full effect on Jul. 22, 2002, when the Brooks Development Authority assumed control of the newly named Brooks City-Base.

Brooks City-Base

Consolidations continued in 1992 with the merging of the Air Force Materiel Command. As a part of the new command, the Human Systems Division at Brooks again changed its name to the Human Systems Center. Although the Air Force continued to shrink, it would be flexible enough to respond on short notice to a wide range of regional crises and contingencies.[6]

Also, the Air Force Center for Environmental Excellence was formed and located at Brooks. This organization has the monumental task of restoring closing installations to their original state and of ensuring that future installations are environmentally safe.[6]

In 1991 four of its laboratories—the Air Force Human Resources Laboratory, the Air Force Drug Testing Laboratory, the Harry G. Armstrong Aerospace Medical Research Laboratory, and the Air Force Occupational and Environmental Health Laboratory, as well as the laboratory function of the USAF School of Aerospace Medicine—combined to became the Armstrong Laboratory, one of four super laboratories in the Air Force.[6]

The 1990s ushered in a new era. For several years the Department of Defense had been looking for leaner, and smarter cost-saving ways to do business. However, this process was intensified with the unexpected collapse of communism in Eastern Europe and the demise of the Soviet Union. Americans expected a peace dividend—a reduction in defense spending. Downsizing became the key word, but Brooks AFB continued to grow.[6]

In November 1987, Brooks celebrated its 70th anniversary. During the celebration the Sidney J. Brooks Jr. Memorial Park was dedicated. This area, along with Schriever Heritage Park, provides a quiet beauty to the base and offers a spot for remembrance of the heritage that is Brooks AFB.[6]

A new Schriever Heritage Park, named for General Bernard A. Schriever, first commander of Air Force Systems Command, was dedicated on Oct. 7, 1986, during the celebration of Aerospace Medical Division's 25th Anniversary. The Aerospace Medical Division was redesignated the Human Systems Division on Feb. 6, 1987.[6]

In the early 1980s, other organizations relocated to Brooks AFB. Among them were the Air Force Human Resources Laboratory and the USAF Occupational and Environmental Health Laboratory. In addition to the Air Force Office of Medical Support, Brooks became home to the Air Force Drug Testing Laboratory and the Air Force Systems Command's Systems Acquisition School.[6]

Visual reality training on pilot/cockpit systems to help make their training more realistic.

After the Vietnam War, the base's mission narrowed to one centered on specific research related to aeronautically rated U.S. Air Force personnel (e.g., pilots and navigators (to include USAF astronauts) and enlisted aircrew. The aerospace era placed new demands on medical research and education, particularly in space medicine. Research efforts at the USAF School of Aerospace Medicine were instrumental in making manned space flight a reality. Researchers continued to study man's interaction with the aerospace environment, seeking ways to maximize a pilot's ability to use modern, high performance aircraft. Flight simulation devices, the centrifuge, altitude chambers, lasers and other specially developed equipment, enabled researchers to perform laboratory studies of man's tolerances in the aerospace environment.[6]

President John F. Kennedy dedicated the School of Aerospace Medicine on November 21, 1963, the day before he was assassinated in Dallas, Texas. This was Kennedy's last official act as president.[11]
