The VT designation is one of the earliest used by the U.S. Navy. A "Torpedo Plane Squadron" existed as early as 1920 but the use of abbreviated squadron designations (such as "VT") did not come into accepted use until 1922. From 1922 to 1930 it designated "Torpedo & Bombing Plane Squadrons" or "Torpedo and Bombing Squadrons". In 1930 it designated "Torpedo Squadrons" until 1946 when all remaining VT squadrons were redesignated Attack (VA) squadrons and the VT designation disappeared. Between 1927 and 1937 a suffix letter was added after the designation number to identify to which fleet or Naval District the squadron belonged: B for Battle Fleet, S for Scouting Fleet, A for Asiatic Fleet or D followed by a Naval District number for those squadrons assigned to Naval Districts. On 15 November 1946 the squadron designation system underwent a major change; the 17 still existing VT and 14 still existing Bombing (VB) squadrons were redesignated Attack (VA) squadrons and the VT and VB designations were eliminated.

The VTN designation was used from 1944 to 1946 to designate "Night Torpedo Squadrons"
