US Navy to Replace F-5 Tigers with Super Hornets in Reserve Aggressor Squadrons

The Northrop F-5 Tiger II has historically played a significant role as a light fighter and aggressor aircraft for the US Navy and Marine Corps, but the Navy is now preparing to phase it out in favor of the F/A-18E/F Super Hornet. The F-5 Tiger II found its niche as an affordable and effective jet used worldwide, especially valued for training enemy tactics through aggressor squadrons. However, facing modern security challenges and the emergence of advanced adversaries, the US Navy aims to upgrade its aggressor fleet to maintain realistic training scenarios.

Dating back decades, the F-5 Tiger II served notably as the template for the aggressor aircraft portrayed in the classic 1986 film Top Gun. In real operations, the Navy and Marine Corps extensively used F-5s to emulate Soviet-era fighter tactics during training exercises. Over time, the aircraft evolved with upgrades such as the ARTEMIS enhancement and integration of ex-Swiss Air Force F-5E/F jets to sustain their role. Despite these efforts, the platform’s aging technology limits its ability to present a credible threat against newer fighter jets encountered in potential conflicts.

Efforts to modernize adversary training reflect a broader strategic shift within US military aviation. The Navy’s interest in replacing its F-5 aggressors with Super Hornets follows similar moves by the Air Force, which inaugurated an F-35A squadron specifically for adversary training. As competitor nations like China field increasingly capable 4.5th- and 5th-generation fighters, having realistic and sophisticated aggressor aircraft provides pilots with vital experience against platforms that closely replicate these threats.

The House Armed Services Committee’s Fiscal 2027 NDAA includes a provision requiring the Secretary of the Navy to submit yearly reports over five years detailing plans and execution for transitioning Navy Reserve F-5 units to F/A-18E/F Super Hornet operations. This formal step underscores the Navy's commitment to fully equip its adversary squadrons with frontline fighter technology. The move will leverage surplus and soon-to-retire Super Hornets, many of which boast combat-proven systems and advanced sensor suites like the AN/APG-79 AESA radar and ATFLIR targeting pods.

The current aggressor fleet comprises approximately 28 single-seat F-5Ns and two F-5Fs, complemented by 22 refurbished Swiss F-5E/F airframes acquired in the 2000s. While these upgrades have extended their usability, the aircraft remain fundamentally constrained by their vintage design and outdated avionics. The T-45 Goshawk remains the Navy’s primary jet trainer, but the Super Hornet’s operational maturity and capability make it a superior choice for replicating complex adversary threats during high-end combat exercises.

Alongside the Navy’s planned transition, several Fighter Squadron Composite units operate in aggressor roles. VFC-12 has already shifted to the Super Hornet, and VFC-13 moved from F-5s to upgraded F-16C/Ds. The remaining F-5 squadrons, VFC-111 and VFC-204, continue to fly Tigers but are slated for upgrade or replacement. The Marine Corps’ F-5 units, VMFT-401 and VMFT-402, also operate the platform with situational awareness systems but face similar replacement considerations outlined in the latest Marine Aviation Plan released in February.

Beyond Super Hornets, the Navy and other US military branches are exploring the use of Collaborative Combat Aircraft (CCA) for future aggressor roles. Notably, autonomous platforms like Anduril's Fury, designated YFQ-44 for the Air Force, are under rapid development. This approach may complement manned aircraft in providing diverse and challenging adversary profiles for pilot training. While the F-5 Tigers’ operational era with the US Navy is drawing to a close, their legacy and role in building combat readiness remain significant within the history of naval aviation.
