Air Transport mission

In January 1960, the 138th FIS was reassigned to the Military Air Transport Service (MATS), trading in its Sabre interceptors for 4-engined C-97 Stratofreighter transports. With air transportation recognized as a critical wartime need, the unit was re-designated the 138th Air Transport Wing (Heavy) with the 125th Air Transport Squadron. During the 1961 Berlin Crisis, both the Group and squadron were federalized on 1 October 1961. From Tulsa, the 125th ATS augmented MATS airlift capability worldwide in support of the Air Force's needs. It returned again to Oklahoma state control on 31 August 1962. Throughout the 1960s, the 125th flew long-distance transport missions in support of Air Force requirements, frequently sending aircraft to the Caribbean, Europe, Australia, Hawaii, Japan, the Philippines, and during the Vietnam War, to both South Vietnam, Okinawa and Thailand. The C-97s were retired in 1968 and the unit was transferred to Military Airlift Command (MAC), being re-equipped with C-124C Globemaster II heavy transports. The Group continued to fly long-distance intercontinental airlift flights until the Globemasters were retired at the end of 1972.

With the retirement of the Globemasters, the 138th was transferred to Tactical Air Command on 25 January 1973, with the 125th Tactical Fighter Squadron being re-equipped with veteran F-100D/F Super Sabre tactical fighter bombers that were returning from the Vietnam War. The Super Sabre was dedicated fighter-bomber, with no concession being made to a secondary air-superiority role and the squadron trained in using the fighter for ground support. Beginning in 1975, the 125th began a NATO commitment, with squadron aircraft and personnel deploying to the United States Air Forces in Europe (USAFE) for Autumn Forge/Cold Fire/Reforger exercises.

In 1978, the F-100s were being retired, and they were replaced with A-7D Corsair II subsonic tactical close air support aircraft from the 23d Tactical Fighter Wing, England AFB, Louisiana along with the 354th Tactical Fighter Wing, Myrtle Beach AFB, South Carolina which were converting to the A-10 Thunderbolt II. The aircraft had excellent accuracy with the aid of an automatic electronic navigation and weapons delivery system. Although designed primarily as a ground attack aircraft, it also had limited air-to-air combat capability. In 1980, the 125th received the new twin-seat A-7K trainer and also received the Low Altitude Night Attack modification to the A-7D.

Modern era

125th Expeditionary Fighter Squadron - General Dynamics F-16C Block 32C Fighting Falcon, AF Ser. No. 86-1589, prepares to take off from Balad AB, Iraq, on 30 Sep 2008.

Early in the 1990s with the declared end of the Cold War and the continued decline in military budgets, the Air Force restructured to meet changes in strategic requirements, decreasing personnel, and a smaller infrastructure. The 138th adopted the new USAF "Objective Organization" in early 1992, with the word "tactical" being eliminated from its designation and becoming the 138th Fighter Group. Tactical Air Command was inactivated on 1 June, being replaced by the new Air Combat Command (ACC).

The 125th Fighter Squadron flew A-7Ds until 1993 when it began to receive Block 42 F-16C/D Fighting Falcons, replacing the venerable A-7D in the attack roles. Most of these aircraft came from the 51st Fighter Wing, Osan Air Base, South Korea and the 363d Fighter Wing, Shaw AFB, South Carolina, which were trading in Block 42s for more advanced F-16s. The 125th, although an Air National Guard unit, which were mostly tasked with air defense of US mainland, was tasked with a conventional attack mission. This was already the case in the A-7D and even in the F-100 era. The squadron was one of the first Air National Guard units to be equipped with the Low Altitude Navigation and Targeting Infrared for Night, or LANTIRN system to be able to illuminate their own ground targets. At the time of conversion this unit was one of the most advanced within the Air National Guard.

125th Expeditionary Fighter Squadron—General Dynamics F-16C Block 42D Fighting Falcon, AF Ser. No. 88-0539. arrives in Iraq on 4 Oct 2011. The squadron deployed in support of Operation New Dawn.

In mid-1996, the Air Force, in response to budget cuts, and changing world situations, began experimenting with Air Expeditionary organizations. The Air Expeditionary Force (AEF) concept was developed that would mix Active Duty Regular Air Force, Air Force Reserve, and Air National Guard elements into a combined force. Instead of entire permanent units deploying as "Provisional" as in the 1991 Gulf War, Expeditionary units are composed of "aviation packages" from several wings, including the active duty Air Force, the Air Force Reserve Command, and the Air National Guard, would be married together to carry out the assigned deployment rotation.

In October 1996, the 125th Expeditionary Fighter Squadron (125 EFS) was first formed from 138th FW personnel and aircraft and deployed to Incirlik Air Base, Turkey, to join with other active-duty and national guard squadrons as part of Operation Northern Watch. This mission was part of a multi-unit Air National Guard "rainbow" deployment involving the Air National Guard block 42 F-16 squadrons. Each squadron provided eight aircraft to a total of 24 aircraft deployed. The 125th EFS returned to Tulsa and was inactivated on 7 January 1997. Further Northern Watch activations of the 125th EFS and subsequent deployments to Incirlik AB occurred in the spring of 1998 and fall of 2001.

The 125th Expeditionary Fighter Squadron has also been deployed to Al Jaber Air Base, Kuwait for Operation Southern Watch in 2001, and to Balad Air Base, Iraq in 2007 and 2008 as part of Operation Iraqi Freedom. In 2011, the 125th EFS deployed to Al Assad, Iraq for the final time to support Operation New Dawn, when more than 200 members deployed there to provide air support to the final drawdown of U.S. and coalition forces, being able to respond quickly to any needs troops in combat may have as they left the country. In 2013, the 125th EFS deployed to Kandahar AB as part of Operation Enduring Freedom. In 2018 the squadron returned to Bagram AB, Afghanistan in support of Operation Freedom's Sentinel and Operation Resolute Support.
