It operates the General Dynamics F-16 Fighting Falcon aircraft conducting advanced fighter training for Republic of Singapore Air Force F-16 pilots.

After training in the United States, it was deployed to Ninth Air Force in England in the spring of 1944, prior to the D-Day landings in France.

During the Battle of the Bulge, it also flew day and night interdiction missions against enemy troop movements, bridges and other targets of opportunity.

RSAF aircrew and maintenance personnel are assigned to the 425th for two years, during which they receive advanced tactics training, participate in Exercise Red Flag, shoot live missiles at Combat Archer, and deploy to locations throughout the United States to participate in composite operations and dissimilar air combat exercises.

The tail code is the standard 'LF' seen at Luke AFB but the country insignia is either RSAF or USAF depending on who owns the aircraft.

In January, training was interrupted when the night fighter school was moved from Florida to Hammer Army Airfield, California.

Subsequently, the squadron had its aircrews posted to various RAF night fighter and signal schools for theatre indoctrination.

[7] Finally, on 18 August 1944, the squadron was considered to be operationally ready for night interception and moved up to Maupertu Airfield (A-15) in France.

As the number of enemy night intruders was small, the squadron also performed offensive interdictionary attacks on Axis forces in France and the Low Countries, 1944, moving eastward through a series of Advanced Landing Grounds until operating from captured Luftwaffe bases in Germany during the spring of 1945.

[6][8] In 1973 with the end of the Vietnam War, the squadron was assigned the task of training the aircrews of nations that had acquired the Northrop F-5E Tiger II under the Mutual Assistance Pact.

[9] In the late 1980s, the fleet of the F-5s was getting rather worn out as a result of sustained exposure to the rigors of air combat maneuvering and training.

[8] In addition, the appearance of a new generation of Soviet fighters made it apparent that F-5Es could no longer perform adequately against Warsaw Pact threats.

The new mission of the 425th was providing advanced weapons and tactics continuation for Republic of Singapore Air Force's F-16 pilots and maintenance personnel.

During their tour of duty they receive advanced tactics training, participate in Red Flag and Maple Flag exercises, shoot live missiles at Combat Archer and deploy to locations throughout the U.S. to participate in composite operations and dissimilar air combat exercises.
