(Aggiornamento Sistemi d'Arma/Modificato – "Weapon Systems Update/Modified") – 49 F-104S-ASA and 15 two-seat TF-104G aircraft upgraded from 1998 to ASA/M standard with GPS, new TACAN and Litton LN-30A2 INS, refurbished airframe, and improved cockpit displays. All strike-related equipment was removed, including the IRST (the small unit known as 'IR-Sight', forward the windshield). The last Starfighters in combat service, the F-104S-ASA/M was withdrawn in October 2004 (the last unit being 10° Gruppo/9° Stormo, Grazzanise), and temporarily replaced by F-16 Fighting Falcons, whilst awaiting delivery of Eurofighter Typhoons.
