[4] The 90th Fighter Squadron origins begin with Special Order 104, Headquarters Kelly Field, San Antonio, Texas, on 25 September 1917.

Both of these detachments had been held from the date of their arrival until 25 September under Recruit Camp Headquarters as a Provisional Squadron.

On 30 September, the squadron left Kelly Field for the Aviation Concentration Center, Camp Mills, Garden City, New York, Long Island, where it arrived five days later.

2 of the Aviation Concentration Center (Hazelhurst Field), where they were quartered with the Headquarters of the First Provisional Wing in Barracks No.

Boarding the famous "Hommes 40, Chevaux 8" railroad box cars (maximum capacity of 40 men or eight horses,) they were shipped to Colombey-les-Belles Airdrome for what they thought would be immediate deployment to the front.

Due to ever-present low clouds and rain, the flyers were forced to drop dangerously close to the ground to carry out their missions, usually in the worst conditions.

[5] The 90th Aero Squadron carried out many reconnaissances, engaged in 23 combats and relieved official confirmation for 7 aerial victories.

The group's lucky "Seven Up" emblem of red dice with white dots reading "7" no matter which way it was tallied, proved prophetic, for they suffered 3 casualties, consisting of 2 killed and 1 wounded.

The 90th earned a positive reputation for its ground attack missions during its continuous participation in the air offensive over Saint-Mihiel.

Its first commander, First Lieutenant William G. Schauffler, designed the 90th's Pair o' Dice emblem displaying natural sevens during this campaign.

The squadron left Colombey les Belles 25 January 1919, en route for the port of embarkation.

It stopped at the pretty little village of St. Denis de Piles, near Libourne, Gironde, and the officers and enlisted personnel occupied excellent billets.

At Kelly Field, Brigadier General William 'Billy' Mitchell, a senior staff officer in the Army Air Service, decided to use this low-level flying experience and the World War I experience of the 3d Group's pilots to create a group devoted to low-level mission of supporting ground troops and attacking ground targets.

The 90th Squadron contributed to the pioneering of new tactics for attack aircraft, delivered US mail in 1934 took part in aerial mapping missions during the 1930s, and attracted significant talent among early military airmen.

Although he could not remember if he was assigned to the 90th during the flight, the Air Force Historical Research Agency confirmed he was a member of the 90th at the time, and his DH-4 aircraft displayed the 90th's pair-o-dice emblem.

Early commanders of the 90th also included Lieutenants Hoyt Vandenberg and Nathan Twining, both of whom later became Air Force Chiefs of Staff.

During World War II, the 90th, now a bombardment squadron, operated in the South Pacific, flying Douglas A-20 Havoc and North American B-25 Mitchell aircraft.

The squadron also participated in the raids on Wewak, New Guinea, which were preemptive strikes that virtually ended the threat of enemy offensive air capabilities.

In September 1946 the 90th moved with the 3d Bombardment Group to Yokota Air Base, Japan, and began training to become combat-ready with the A-26, which was redesignated the B-26 Invader.

In November 1965 the wing moved to Bien Hoa Air Base, South Vietnam, during the buildup of forces.

On 31 October 1970 the 3d Tactical Fighter Wing ended its duties in Vietnam and remained active in 'paper' status until it moved to Kunsan Air Base, South Korea, in March 1971.

On 15 April 1972 the 90th moved again, this time to the 18th Tactical Fighter Wing at Kadena Air Base, Okinawa, Japan.

During the late 1970s and 1980s, the squadron provided training and support to other units throughout the Pacific, as well as ensuring the readiness of its own pilots and aircraft.

[4] In June 1991 Mount Pinatubo erupted in the Philippines and the Air Force quickly decided to evacuate its personnel and equipment from Clark AB.

This two-seat dual role updated version of the F-15C Eagle had more survivability enhancements than any other fighter aircraft at the time.

[4] Since arriving in Alaska, the 90th Fighter Squadron participated in numerous training exercises in the lower 48 states and other areas of the world.

While deployed the unit flew more than 1100 sorties over the Korean Peninsula and provided two important flights to distinguished visitors, Republic of Korea Air Force Brigadier General Ko and Republic of Korea General Kim, Commander Korean Ground Forces.

This upgrade allowed the aircraft to carry and use more advanced weaponry, including the Joint Direct Attack Munition and eventually the Small Diameter Bomb.

Replacing those F-15Es, the 90th began receiving the advanced F-22 Raptor in August 2007, which greatly enhanced the 90th Fighter Squadron's ability to perform its duties.

[8] In August 2024 some of squadron's F-22 Raptors jets have arrived in the Middle East in a show of force meant to deter Iran and its proxies from attacking Israel following the assassination of a Hamas leader.
