Armament

USS Semmes (DD-189/AG-24) was a Clemson-class destroyer in the United States Navy during World War II. She was the first Navy ship named for Commander (USN), Rear Admiral (CSN), Brigadier General (CSA) Raphael Semmes (1809–1877).

Service history

Semmes was

4"/50 caliber guns rather than the normal armament for Clemson-class destroyers of four such guns. This armament was retained until at least 1931.[4][5] A few months later, she was the first to navigate using only the Ambrose Channel pilot cable.[6][7]

Following shakedown, Semmes participated in exercises along the northeast coast until January 1921 when she sailed south for winter fleet maneuvers in the Caribbean. From there, she transited the Panama Canal to cruise off the west coast of South America and returned to the Caribbean in late February to conduct further exercises out of Guantanamo Bay. In late April, she resumed operations out of Norfolk, Virginia.

The destroyer was ordered inactivated in 1922; and, on 12 April, entered the

Philadelphia Navy Yard
where she was decommissioned on 17 July 1922.

Reactivated 10 years later, she was transferred to the

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
.

Although not officially redesignated as an auxiliary ship, AG-24, until 1 July 1935, Semmes was assigned to Experimental Division 1 and, with assigned submarines, tested and evaluated underwater sound equipment into the 1940s. In May 1939, Semmes took part in the recovery efforts for the submarine Squalus.[8]

Semmes was fitted with the XAR air search radar in July, 1941 This was the prototype for the SC, SA, and SK series of radars.[9]

After the entry of the United States into World War II, Semmes added escort missions, training services for the Key West Sound School, and antisubmarine patrol work to her duties.

At

Cape Lookout, collided with a British armed trawler, Senateur Duhamel. The latter sank; and, after assisting the survivors, Semmes put into Morehead City, North Carolina
, for temporary repairs.

Permanent repairs were completed at Norfolk on 3 June and the former destroyer resumed her test and evaluation, patrol, and escort work which she continued through the end of the war in Europe. After the capitulation of

Submarine School and to the Fleet Sonar School

Semmes can be seen briefly as AG-24 in the 1943 movie

Fate

On 21 May 1946, Semmes again entered the

Philadelphia Navy Yard for inactivation. Decommissioned on 2 June, her name was struck from the Navy list on 3 July; and her hulk was sold for scrapping to the Northern Metals Corporation, Philadelphia
on 25 November. She was scrapped the following year.
