History
Clark Air Base was originally established as Fort Stotsenburg in Sapang Bato, Angeles, Pampanga in 1903 under control of the U.S. Army. A portion of Fort Stotsenburg was officially set aside for the Aviation Section of the Signal Corps and named Clark Field in September 1919 after Harold M. Clark, who died in a seaplane crash in the Miraflores Locks, Panama Canal Zone on May 2, 1919. Clark later served as a landing field for U.S. Army Air Corps medium bombers and accommodated half of the heavy bombers stationed in the Philippines during the 1930s. It was very large for an air field of its day, and in the late summer and fall of 1941, many aircraft were sent to Clark in anticipation of a war with

The base was attacked by Japanese forces on December 8, 1941 destroying dozens of aircraft and the base was evacuated on December 24. American forces on Bataan and Corregidor fell on April 9, 1942 leading a few days later to the brutal Bataan Death March. Clark became a major center for Japanese air operations throughout the war. Japanese aircraft flying out of Clark participated in the

During the war, Allied prisoners on the Bataan Death March passed by the main gate of Clark Air Base as they followed the railway tracks north towards Camp O'Donnell. During October through January 1945 American air raids damaged or destroyed over 1500 Japanese aircraft. On January 31, American forces regained possession of Clark Field after three months of fierce fighting to liberate the Philippines. It was immediately returned to U.S. Army Air Forces control.

Clark and the other United States bases in the Philippines became the focus of significant controversy in the Philippines during the Dictatorship of Ferdinand Marcos, becoming one of the most common points of contention raised during numerous major protests. Meanwhile, Marcos was able to use ongoing negotiations for the renewal of the US bases treaty as a way of limiting US government criticism and intervention against human rights abuses, attacks on press freedom, and the shuttering of democratic institutions in the Philippines. When the Marcoses were deposed in February 1986, they fled the Presidential Palace and were flown to Clark, and it was from there that the US government flew them into exile in Hawaii.

lowered the U.S. flag and transferred Clark Air Base to the Philippine government. With the United States military's withdrawal from Clark, the base was systematically looted by the local population and was left abandoned for several years. It finally became the Clark Freeport Zone, the site of Clark International Airport (CIA) and parts of it are still owned and operated by the Philippine Air Force, retaining the same name, Clark Air Base.
In June 2012, the Philippine government, under pressure from Chinese claims to their seas, agreed to the return of American military forces to Clark.
Military units
During much of the Cold War, Clark Air Base's activity largely revolved around the 405th Fighter Wing, later renumbered as the 3rd Tactical Fighter Wing in September 1974 and its fleet of F-4 Phantom II fighter jets. It also hosted an interceptor squadron and a flight school, all of which flew a variety of other combat aircraft. Transient aircraft of many types, especially cargo jets, were common.
Fighter planes regularly visited to participate in aerial warfare exercises at Crow Valley about to the northwest. In November 1973, headquarters for the 374th Tactical Airlift Wing was transferred from Ching Chuan Kang Air Base, Taiwan, to Clark Air Base. With this move came two squadrons of C-130E transport aircraft, the 21st Tactical Airlift Squadron and the 776th Tactical Airlift Squadron.

Culture
Clark Air Base was arguably the most urbanized military facility in history and was the largest American base overseas. At its peak around 1990, it had a permanent population of 15,000. It had a base exchange, large commissary, small shopping arcade, branch department store, cafeterias, teen centers, hotel, miniature golf, riding stables, zoo, and other concessions.

bars were legendary, particularly around the red-light district on Fields Avenue. As a result, Clark's servicemen's clubs were under considerable pressure to serve its members with wholesome entertainment. All three were large-scale operations: the Officer's Club (CABOOM) near the parade ground, the Top Hat Club for non-commissioned officers (NCOs) near Lily Hill, which moved to near the Silver Wing in 1986, and the Coconut Grove Airmen Open Mess (AOM) housed in a large vaulted room that contained palm trees.
The officer's club featured a four star dining room, but catered to NCO's during lunchtime. The airman's club got first dibs on Broadway shows and swing bands due to an agreement that whoever paid transportation costs got priority. The NCO club came second. The airman's club had numerous theme bars and rental girls for dance partners during swing band tenures on the large dance floor. The club security (bouncers) were outfitted in formal PI wear each evening of a different hue. The PI formal wear for men was lace shirts (the barong Tagalog) with French cuffs, traditional and very elegant. The volume of enlisted troops flowing through PI to Vietnam created a large audience for AOM offerings. The NCO Club was still a very extensive operation and operated an upscale dining room, an in-house thrift shop, a pinball arcade, and a calendar of daily activities. It regularly brought major bands and artists from the United States to perform.
At least a hundred sponsored clubs and organizations were active on the base, including the Knights of Columbus, a Latino American club, the Civil Air Patrol, and martial arts dojos. Two major movie theaters operated daily: the Bobbitt Theater which played first-run films, and the Kelly Theater which showed older releases. By 1988 the Kelly Theater ceased showing films and was used mainly for Commander's Calls and large squadron-sized meetings. In the late 1960s and early 1970s, movies were also shown at the Bamboo Bowl, the football stadium on base.
The Bamboo Bowl, later renamed Challenger Field, was used mainly for high school football games as the school did not have its own athletic field. In addition to high school football games, it also hosted recreational league football games for ages 8–18. The high school football teams were included as part of the recreational league. The base's sole high school, Wagner High, had multiple football teams. It was also used for the base's 11-man tackle football league, which not only included teams from Clark but from Subic Naval Base as well.
To keep the residents entertained at home, Clark had an active broadcast center called FEN, or Far East Network Philippines, a division of American Forces Network. A television station broadcast on Channel 8, then Channel 17 after 1981. It showed about 20 hours per day of syndicated programs from the "big three" networks in the United States, with local news and talk programs. The content was locally syndicated until 1983 when it began airing live programming by satellite from Los Angeles.
FEN had two 24-hour radio stations: an AM station which broadcast news and popular music, and stereo FM which was dedicated to easy-listening and classical music. Local Filipino TV also aired newer American shows than FEN did. Unlike the local TV stations in Europe, they were broadcast in the same format as American TV and not dubbed in Tagalog, the local language. Likewise, several American-styled radio stations in Manila were popular with Clark residents: one notable example in the 1980s was 99.5 DWRT-FM.
Two major annual events at Clark were the annual Chili Cookoff, held near the Silver Wing recreation center around September, and the Happening on the Green ("the HOG") in February. The HOG attracted thousands of residents. Amusements and rides were built and operated not only by Filipino entertainment contractors but also by individual Air Force units seeking to boost unit morale, showcase their talents, and raise unit funds.
Because of the warm climate and the large number of units, slow pitch softball tournaments were held quarterly. There were at least two gymnasiums, three walking/running tracks and seven softball fields on base. There were also tennis courts, a clubhouse with tennis merchandise, and tennis pros available for a couple of dollars per hour to hit with you at any time. They had a local tournament each year.

Education
The Department of Defense Dependents Schools (DoDDS) operated six schools at Clark Air Base, serving children from kindergarten to twelfth grade.
* Elementary schools (kindergarten-5th grade): MacArthur Elementary School, V. I. Grissom Elementary School, and Wurtsmith Elementary School. The latter two were located in the hill housing area. Most officers and senior enlisted families attended Grissom.
* Middle schools (6th–8th grade): Lily Hill Middle School, and Wagner Middle School. The latter primarily served the hill housing area and officer dependents.
* High school: Wagner High School, known as Clark Dependent School in the 1950s and Wurtsmith Memorial High School in the 1960s.
Clark was also home to several community colleges, namely the Pacific Far East Campus of Central Texas College. Most classes were held in the evenings at Wagner High School.

Climate
Climate at the base is characterized by two distinct seasons: a "dry season" from November through April, and a "rainy season" with monsoon rains that occur from May through October. During the dry season, winds are usually northeasterly and skies are fair. Some afternoon showers tend to appear by April. April brings the highest average temperatures of any month, though the hottest days of the year tend to occur in May.CLIMATOGRAPHY OF THE UNITED STATES NO. 81, Monthly Normals of Temperature, Precipitation, and Heating and Cooling Degree Days, No. 91, Pacific Islands, NATIONAL ENVIRONMENTAL SATELLITE, DATA, AND INFORMATION SERVICE. Due to the very dry state of vegetation at this time, ash and soot often falls on Clark Air Base as farmers burn their fields for planting. During drought years, wildfires occasionally broke out in the overgrown areas west of the golf course and northeast of the airfield.
Rainy season normally arrives during the month of June. July and August are wet, with many dark overcast days, and frequent afternoon and evening rains. Typhoons are common in late summer and fall, approaching from the east. They are rarely strong at Clark Air Base as the facilities are far inland, and the typhoon circulation is disrupted by the Sierra Madre mountain range on the east coast. Rain and typhoon activity diminishes sharply by November and December, when the dry season arrives once again. Temperatures are at their coolest, with nighttime lows sometimes falling to 64 °F (18 °C) or lower.
From 1953 to 1991, the mean daily low was and the mean daily high was , with April being warmest and January coolest. The average annual rainfall was .
