USN:
Clemson-class destroyer USS Semmes (DD-189) during the period of her very brief career as a navy destroyer (1920-1922). Reactivated 10 years later, she was transferred to the
United States Coast Guard to serve in the
Rum Patrol. She was commissioned in that service on 25 April 1932. As a Coast Guard destroyer, she was reconditioned at
Boston, Massachusetts and based at
New London, Connecticut whence she operated from 25 September until detached for two months duty with the Navy on 7 September 1933. On 10 November, she returned to New London and resumed operations for the
Treasury Department. On 20 April 1934, the destroyer was returned to the Navy and was recommissioned as an experimental ship in accordance with the
London Treaty limiting naval armament.
USS Wyoming (BB-32) entering drydock
USS Mississippi (BB-41) forward turrets circa 1924. While conducting gunnery practice off
San Pedro on 12 June 1924, there was an explosion in her forward superfiring Gun Turret No. 2. The resulting fire asphyxiated 44 members of the turret crew. Upon returning to port the gunpowder that was still in Gun No. 5, the remaining gun in the turret, exploded and killed four members of the rescue team. The shell that was in the gun narrowly missed the passenger ship
Yale. This was, at the time, the deadliest peace-time disaster in the Navy's history
