Torpedoman's Mate (abbreviated as TM) is a United States Navy occupational rating. It was disestablished on submarines in 1995 and on surface ships on 1 October 2007. Surface torpedomen were merged into the gunner's mate rating, while submarine torpedomen were merged into the machinist's mate (non-nuclear) rating, becoming MM(W) or machinist mates (weapons). It was re-established on 30 September 2019 via NAVADMIN 225/19. The TM rating badge will be the same one in use when the rating was disestablished in 1995. The re-establishment of the rate is in direct support of the Sailor 2025 and Rating Modernization initiative, which aim to empower Sailors and expand professional development opportunities.
