The TI were used post-war by several navies with different modifications and designations (Marina Española: G-7a, Bundesmarine: DM11, Royal Danish Navy: T1T, Royal Norwegian Navy: T1 mod 1). Last known operator was RNoN with the T1 mod 1 (G7a with wire-guidance: Although four modifications to the torpedo were carried out over the years – the last with computerised control in 1992 – the same designation "mod 1" was applied throughout its service). In the RNoN, T1 mod 1 was used from FACs (until 1992), submarines (until the 1980s) and Coastal artillery shore batteries (until 1999).
