USS Ammen (DD-527), a , was the second ship of the United States Navy to be named for Rear Admiral Daniel Ammen (1820–1898). Construction and commissioning Ammen was laid down on 29 November 1941 at San Francisco, California, by the Bethlehem Steel Corporation; launched on 17 September 1942; sponsored by Miss Eva Ammen; and commissioned on 20 March 1943, Commander John C. Daniel in command. Service history Alaska, March–November 1943 Ammen put to sea on 30 March bound for San Diego where she completed her shakedown training. The destroyer departed San Diego on 20 April and arrived in San Pedro the following day. Two days later, she embarked upon a voyage to Alaskan waters as part of the screen for Task Force 51 (TF 51), built around . The task force arrived at Cold Bay, Alaska, on 1 May and, 10 days later, participated in the landings on Attu Island. During that operation, Ammens primary responsibility consisted of providing antisubmarine and antiaircraft protection for the ships of the invasion force. Since the air threat never materialized and the submarine menace proved almost as benign, she fired no shots at the enemy but struggled mightily against the inhospitable Aleutian climate. At the conclusion of her part in the operation, Ammen headed back to California, arriving in San Diego on 31 May. The destroyer underwent two weeks of repairs at San Diego and then moved north to San Francisco where she resumed post-shakedown availability. On 11 July, she departed San Francisco in the screen of another convoy bound for Alaska. She escorted the convoy to a point about 900 miles from Adak Island where other escorts took over the mission. Ammen returned to San Francisco on 21 July but remained there only eight days. On 29 July, the destroyer put to sea with another Alaska-bound convoy. She shepherded her charges into port at Adak on 5 August and began preparations for the occupation of Kiska. That operation proved to be a walkover for the simple reason that the Japanese had evacuated Kiska. The destroyer returned to Adak on 12 September and remained there until 24 September. She put to sea again on the 24th, made a brief stop back at Kiska on the 25th, and then headed on to Pearl Harbor. Ammen arrived at her destination on 2 October and spent the ensuing nine days practicing gunnery, torpedo, and antisubmarine warfare (ASW)
