The F-16 is a lightweight, multirole fighter capable of air-to-air, CAS, SEAD, interdiction, FAC-A, tactical nuclear delivery and all-weather strike missions.
The “Viper” makes up roughly half the fighter inventory, carries the majority of PGMs in service, and is one of the most maneuverable fighters ever built. The prototype YF-16 first flew Feb. 2, 1974, competing in the USAF Lightweight Fighter competition. After selection, F-16A flew on Dec. 8, 1976, followed by the two-seat F-16B on Aug. 8, 1977. Deliveries began in August 1978, and USAF declared F-16A IOC in October 1980.
F-16C/D deliveries began at Block 25 in 1984, adding the APG-68 radar and AMRAAM missile as well as cockpit, airframe, and avionics improvements. Block 30/32 added the HARM missile and more powerful engines, and Block 40/42 introduced the terrain-following LANTIRN pod and wide-angle HUD for high-speed night/all-weather penetration. These airframes boasted higher takeoff weight and G-limits and an expanded flight envelope starting in 1988.
Block 50/52 was introduced to replace the F-4G in the “Wild Weasel” SEAD-role armed with the HARM missile, longer-range radar, and even higher-performance engines. The F-16 entered combat during Desert Storm in 1991 and scored its first USAF air-to-air kill during Southern Watch on Dec. 27, 1992.
The fleet is now cockpit-standardized with color MFD, modular mission computer, Helmet Mounted Integrated Targeting (HMIT), and Link 16. The Operational Flight Program (OFP) continuously updates the F-16’s software, most recently adding JASSM-ER and enhanced AMMRAM.
USAF is retiring 49 of the older Block 30-32 aircraft through FY25 while simultaneously modernizing late-block aircraft as a low-cost “capacity” fleet to augment fifth-generation fighters. Modernization centers on the new AN/APG-83 AESA radar, specifically aimed at countering cruise missile threats to the homeland. An initial 72 AESA-equipped aircraft were fielded under an emergent operational need and a further 443 will be upgraded. A total of 450 airframes are also undergoing SLEP to stretch beyond 8,000 flying hours.
USAF aims to expand digital RWR upgrades into a future, fully integrated, internal EW suite for active jamming as well as self-defense. The rapidly developed Integrated Viper Electronic Warfare Suite (IVEWS) will leverage AESA and will be rapidly upgradable against new threats with fleet mods potentially starting in FY25. Comm suite upgrades will integrate Mobile User Objective System (MUOS) secure, jam-resistant BLOS and NATO-interoperable LOS SATURN, while MIDS/JTRS will provide higher capacity, jam-resistant Link 16.
Other efforts include modernizing mission computer and cockpit displays in conjunction with offensive/defensive upgrades, and Mode 5 IFF. USAF plans to continue upgrading the F-16 to keep pace with threats through 2040 or beyond. The Indiana ANG’s 122nd FW reverted to F-16 operations in 2023, and Idaho’s 124th FW will also transition in 2026 as the A-10 fleet is retired. Over the last year, three F-16s were lost in separate crashes in South Korea, while a fourth was severely damaged in a ground mishap at Misawa.
