The U.S. Navy's ARTEMIS project reached a crucial milestone as RUAG, a subcontractor for Tactical Air Support (Tactical Air), handed over the initial F-5 jet of a total of 22 aircraft. Tasked with inspections, structural work, and engine overhauls, RUAG's role underscores the collaborative effort in modernizing the F-5 fleet.

In July 2022, Tactical Air secured the ARTEMIS F-5 modernization contract from the U.S. Navy, with RUAG appointed to provide maintenance services and overhaul GE-J-85 engines. Acquired from the Swiss government years ago, these F-5 aircraft are pivotal for the Navy's Red Air training program, aiming for reliable operation until 2040 and beyond.

To enhance training realism, the ARTEMIS project includes avionics upgrades, safety enhancements, and an obsolescence program ensuring maintenance and spare parts availability. The scope of structural work on each F-5 varies based on flight hours and condition, with RUAG currently engaged in four aircraft.

The delivered F-5 jet will undergo further modernization in Jacksonville, Florida, by Tactical Air, including the installation of a new cockpit and advanced avionics. Beyond bolstering Swiss F-5 fleet expertise, this project creates additional business opportunities for RUAG, reflecting a significant step forward in U.S. Navy training capabilities.

About ARTEMIS F-5

The ARTEMIS F-5 isn't a new variant of the F-5 aircraft, but rather a modernization program  for existing F-5E/F Tiger II aircraft previously used by the Swiss Air Force.  The U.S. Navy acquired 22 of these retired jets and is upgrading them through the ARTEMIS program to serve as adversary aircraft for pilot training. 

Specific details about the exact upgrades being implemented haven't been entirely released, but we do know the program includes:

• New glass cockpit with modern avionics
• Engine modifications and overhaul
• Structural component replacement

These upgrades are expected to bring the F-5s up to the F-5N+/F+ configuration, which will enhance their performance and make them more capable training partners for Navy and Marine Corps pilots. 

The ARTEMIS program is expected to be completed in 2028, with the first upgraded aircraft delivered by mid-2025.
