Stockton Metropolitan Airport is a joint civil-military airport in unincorporated San Joaquin County, California, southeast of downtown Stockton. It is owned by the County of San Joaquin.

The National Plan of Integrated Airport Systems categorized it as a primary commercial service airport. Federal Aviation Administration records say it had 36,935 passenger boardings (enplanements) in calendar year 2008, 28,368 in 2009 and 50,632 in 2010.

History

In the months preceding World War II, the U.S. Army entered into the first of many lease agreements with the City of Stockton (on August 15, 1940) to build and operate an Army training facility at Stockton Municipal Airport.

World War II Stockton Army Airfield was initially garrisoned by the 68th Air Base Group (Special) under the Air Corps Advanced Flying School. Between 1940 and 1945, Stockton Field served as a training installation under the West Coast Training Center (later Western Flying Training Command) headquartered at Santa Ana Army Air Base. Known sub-bases and auxiliaries of Stockton AAF were: Kingsbury Auxiliary Airfield (No 1) New Jerusalem Auxiliary Airfield (No 2) Modesto Auxiliary Airfield (No 3)n Tracy Auxiliary Airfield (No 4) Franklin Auxiliary Airfield (No 5)

In May 1944 all of the facility was consolidated into the 3033rd Army Air Forces Base Unit. Given the airfield's proximity to logistical facilities under the Army Air Forces and Army Service Forces, the site soon became a logistical hub for the U.S. Army in general and the Army Air Forces in particular. This resulted in an increased number of transport aircraft passing through Stockton Field. Military warehouse facilities included of tracks connected to the adjacent Southern Pacific and Western Pacific Railroads for delivery and distribution of a daily average of 200 railcars of military supplies.

On March 2, 1945, the final class completed training and Stockton AAF was transferred from the control of the Western Flying Training Command to the Air Transport Command. With this transfer, the 3033rd AAFBU was redesignated as the 591st AAFBU.

Postwar use In October 1946 Stockton AAF was declared surplus. As 1,044.18 acres were in the process of being transferred to the War Assets Administration for disposal, 71.36 acres, consisting of a major portion of the former cantonment area including housing, storage facilities, and a sewage disposal plant, were leased to U.S. Army's Stockton General Depot located to the south in nearby Lathrop.

The City of Stockton and the County of San Joaquin resumed operating the former Stockton Municipal Airport on December 16, 1946, under a joint (interim) license. On the 1,044.18 acres of leased land (950 acres of which comprise the airport now under license) there were approximately 175 buildings, including 50 airport-related structures which were included in the above described license. The buildings were primarily the Quartermaster 700-series and 800-series type construction with concrete foundations, wood floor, composition roof, and wood lap siding.

United States Army use On January 29, 1947, the 71.36-acres of former Stockton Field retained by the U.S. Army was officially named the Stockton General Depot Field Annex, then renamed Sharpe General Depot Field Annex in 1948, when Stockton General Depot was redesignated as Sharpe General Depot. The U.S. Army, with the exception of the Sharpe General Depot Field Annex, left Stockton Field by January 31, 1948; the same date that the City of Stockton and the County of San Joaquin jointly assumed administration over the airport (Stockton Record 1964).

Korean War use Sharpe General Depot Field Annex was formed from two parcels of land adjacent to the southwest portion of the current Stockton Metropolitan Airport. Sharpe General Depot Field Annex was operated by the U.S. Army as a separate, self-contained military post under Sharpe General Depot. With the rapid expansion of depot operations and facilities that occurred with the outbreak of the Korean War in June 1950, Sharpe General Depot Field Annex's name was changed to Sharpe General Depot Troop Field Annex to reflect its support mission. During this period, the site was used primarily for family housing, recreational, and other support facilities for Sharpe General Depot. One of the tenants was the 164th Field Artillery Battalion of the California Army National Guard, who occupied a small part of the Sharpe General Depot Troop Field Annex until a new National Guard Armory was built on State-owned land south of the site in 1952.

Sixth Army & Army Material Command use On July 8, 1957, the City of Stockton transferred half of its interest in the Stockton Municipal Airport by Grant Deed, and San Joaquin County assumed administration over the airport (subject to certain reservations, restrictions and conditions according to the "Agreement" with the United States of America dated December 23, 1948 (Appendix A)).

The end of the Korean War caused more mission changes at Sharpe General Depot and the Sharpe General Depot Troop Field Annex. Sharpe was selected as a location for Cold War storage of surplus military diesel locomotives. After application of lubricant preservatives, each locomotive was placed within an individual cocoon protected by an electrically operated, automatically controlled dehumidifying system. In 1958, the Sharpe General Depot received a Fourth Echelon Air Maintenance Support mission on U.S. Army aircraft within the Sixth U.S. Army Area. The Site then served as home to the Sixth U.S. Army Aircraft Field Maintenance Activity operated by Detachment 3, 6932nd Service Unit. This unit provided maintenance support to U.S. Army rotary and fixed-wing liaison aircraft in the Sixth U.S. Army area and occupied Buildings 1000, 1001, and 1003. The site also was the home of the 30th Engineer Group (Topographic) and the 521st Engineer Company (Topographic, Aviation). During 1959 and 1960, construction of a new airstrip, hangar and shop at Sharpe Army Depot curtailed the military's use of Stockton Airport. In June 1961, the Aircraft Field Maintenance Activity was transferred to Fort Ord, California. By July 1962, the Army Material Command was established with several sub-commands, including the Supply and Maintenance Command. This brought about another name change when Sharpe General Deport became Sharpe Army Depot Field Annex.

Vietnam War use On July 11, 1964, Stockton Municipal Airport was officially renamed the Stockton Metropolitan Airport, reflecting its changing role as a civil airport. Thirty new military family housing units were also built in 1964 at Sharpe Army Depot Field Annex, resulting in the closure of older family housing units at the site.

In the last months of 1965, support to Army Aviation expanded again as a result of the U.S. Army's role in Southeast Asia. As the Vietnam War continued, so did Sharpe Army Depot Field Annex's mission. Sharpe became the Army Material Command's key west coast installation and the Army's chief provider of supplies for United States military personnel in Vietnam. Cocoons were removed from fourteen of the stockpiled diesel locomotives. Twelve of the locomotives were sent to other military bases while two remained at Sharpe to accept delivery and expedite distribution of a daily average of thirty carloads of military supplies. Rail movements represented approximately 38 percent of all freight handled at the base. In April 1966, the first units of the Headquarters and Headquarters Company, 56th Quartermaster Depot began to arrive at the Site, followed by units of the Headquarters and Headquarters Company, 58th Field Depot in July.

By 1967, the Headquarters Commandant of the Sharpe Army Depot Field Annex had the responsibility to command troops assigned to Sharpe Army Depot Field Annex. This included the supervision of all attached and tenant units, Special Services, Annex Services, Education Center, Officers Open Mess and Non-commissioned Officers Club, including support for Army Reserve, Army National Guard and transient units.

In January 1966, an Army clothing store was transferred from Sacramento Army Depot and reopened in Building T-88 at the Site. An AAFES Branch Exchange of the Presidio of San Francisco was also established in Building T-137. On-post housing at Sharpe Army Depot Field Annex was limited, causing 44 sets of "inadequate quarters" to be established at the site, whereby old barracks buildings were converted into "apartment-type quarters" with two apartments upstairs and two downstairs. To further accommodate the increase in soldiers now stationed at Sharpe Army Depot Field Annex, the site now provided many additional services such as laundry, dry cleaning, and medical facilities.

In the early 1970s, the need for soldiers garrisoning Sharpe Army Depot Field Annex decreased as military positions were converted to Department of the Army Civil Service positions. Due to the shift in staffing, Sharpe Army Depot determined that it no longer required the Field Annex site and began the process of disposing of the Sharpe Army Depot Field Annex.

Deactivation (Regular Army) Sharpe Army Depot Field Annex was vacated in 1973, ending the U.S. Army's presence on the field with all of the land and buildings reverting to San Joaquin County. A few original World War II structures still remain including the American Legion Sharpe General Depot Post 632 currently occupying a World War II era mess hall on the Sharpe Army Depot Field Annex property located at Building 372, 1700 Northrop Street.

Military facilities and activities Although the active duty Regular Army departed the airport location following the closure of the Sharpe Army Depot Field Annex, the airport continues to retain a military presence in the form of both ground and Army Aviation activities of the California Army National Guard. These facilities include a National Guard Armory, Field and Combined Support Maintenance Shops, and an Army Aviation Support Facility (AASF) just south of the former Field Annex site. The Army National Guard aviation presence accounts for the airports continued designation as a joint civil-military airport. The main aviation units at the airport are Headquarters and Headquarters Company and Company A of the 3rd Battalion, 140th Aviation Regiment, operating the CH-47 Chinook and the UH-72 Lakota.
