The 25th Fighter Squadron was originally created as the 25th Pursuit Squadron and activated at Hamilton Field, California, on 15 January 1941. By March it was assigned to the 51st Pursuit Group at March Field, California. In July the squadron received P-40 Warhawk aircraft.
World War II
The 25th sailed to combat operations in the Pacific Theater aboard the SS President Coolidge on 11 January 1942. The squadron was part of the first deployment of U.S. forces leaving the mainland after the declaration of war. The journey to Melbourne, Australia, took 20 days. By late March the 25th Pursuit Squadron had arrived in Karachi, India, and set up wartime operations.
The 25th flew its first aerial combat mission over "The Hump" on 25 September 1942, flying a combat escort mission. After the squadron moved to Dinjan in Assam, India, combat activity increased. Due to the terrain, the pilots would usually "drag in" on their passes. It was there that the 25th picked up the name "Assam Draggins."
Operations from Dinjan were concentrated against the Japanese in northern Burma along the upper Chindwin and Irrawaddy Rivers. In February 1943 the 25th Fighter Squadron was tasked to defend Fort Hertz near Myitkyina. Fort Hertz was a vital cog in air operations near "The Hump." The 25th bombed and strafed enemy troops, concentrations, supply dumps, bridges, and enemy communication lines for twelve consecutive days, but failed to slow the Japanese advance on Fort Hertz. B-25 heavy bombers were needed to halt the Japan's drive, but none were available. Lieutenant Colonel John E. Barr, the executive officer for the 51st Fighter Group, modified a P-40 to carry 1,000 pound bombs, and by May 1943, the Japanese offensive had been halted .
The 25th Fighter Squadron encountered more combat activity than any other unit within the 51st Fighter Group during the war. The squadron returned to the United States and was inactivated on 12 December 1945.
On 15 October 1945, the 25th was re-activated at Naha Air Base, Okinawa, where the squadron was assigned P-47 Thunderbolt and P-80 Shooting Star aircraft. As part of the occupation force, the 25th provided defense for the Ryukyu Islands.
The 25th was placed on alert when hostilities erupted in Korea in June 1950. The unit was reassigned to Itazuke Air Base, Japan, in September, and to Kimpo Air Base, Korea, by October. The Chinese People's Volunteer Army intervention in December 1950 forced a retreat of U.N. forces from North Korea into the South. The 25th flew more than 21 sorties each day that month to save the 2nd Infantry Division, which had been cut off by the enemy near Kunuri, from being overrun. Air cover was officially credited with preventing disastrous losses to the division.
On 20 November 1951, squadron pilots received their new F-86 Sabre aircraft and went to face the Chinese, North Korean, and Soviet pilots in their MiG-15 aircraft. Major William T. Whisner Jr. got his fifth MiG kill on 23 February 1952, becoming an Ace.
When the 51st Group adopted a checkered design for its F-86 tail markings, it also received the designation "Checkertails". The red squadron colors appeared in the design. Thus, the Assam Draggins of World War II became known as the "Checkertails" of the Korean War.
Post Korean War
After the war, the 25th was assigned to the 51st Fighter-Interceptor Wing at Naha Air Base, Okinawa. While there, the pilots were deployed for one week at a time to Kadena Air Base, Okinawa. From 1960–1965, the 25th Fighter Squadron remained in a state of suspended animation with virtually no mission and only 20 percent manning. On 17 June 1965, the unit was re-designated the 25th Tactical Fighter Squadron and assigned to the 33d Tactical Fighter Wing at Eglin Air Force Base, Florida.
On 31 May 1968, the 25th was assigned to the 8th Tactical Fighter Wing and stationed at Ubon and Udorn Royal Thai Air Force Bases, Thailand, once again seeing combat in the skies of Vietnam. Flying F-4 Phantom II aircraft, the 25th received the Presidential Unit Citation (1971), the Republic of Vietnam Gallantry Cross with Palm (1967–1973), and five Air Force Outstanding Unit Awards (1967–1973).
Post Vietnam War - Present
When the Air Force began its withdrawal from Thailand, the 25th was reassigned the 18th Tactical Fighter Wing at Kadena Air Base, Okinawa, where it remained until 1 February 1981. On that date, the 25th was relocated without personnel or equipment to Suwon Air Base, Republic of Korea, and assigned to the 51st Composite Wing (Tactical).
On 28 January 1982, the 25th received its first A-10 Thunderbolt II aircraft. The squadron's presence helped maintain a peaceful armistice between North and South Korea until 2 October 1989. It was during that time that the 25th began transferring aircraft to the 19th Tactical Air Support Squadron and other stateside units and inactivated on 1 July 1990. On 1 October 1993, the 25th Fighter Squadron was activated under the 51st Wing at Osan Air Base, Republic of Korea, under the command of Lieutenant Colonel Syd McPherson. It has since added six A-10 aircraft to its fleet, making it a dual qualified A/OA-10 squadron.
The official motto of the 25th FS is "PILSUNG!" meaning certain victory in Korean. It is customary/mandatory that any time the number 25 or any variation of 25 (2.5, .25, etc.) is said, every person assigned to the 25th will shout a hearty "PILSUNG!" under any circumstance, regardless of who said it or who was briefing.
The Squadron is unofficially known as the "Flying Elvis's".
