1st USS Sentry

The first USS Sentry (AM-299), an Admirable-class minesweeper, was laid down on 16 May 1943 by the Winslow Marine Railway and Shipbuilding Co., Seattle, Wash., launched on 15 August 1943 and commissioned on 30 May 1944 with Lt. Thomas R. Fonick as the commanding officer.

After shakedown, Sentry sailed from San Francisco on 28 August 1944 and joined the 7th Fleet at Manus on 6 October for the Leyte invasion. She arrived off the Leyte beaches on 17 October and carried out a three-day pre-invasion sweep. During and after the initial landings she continued sweeping and provided antiaircraft support. Sentry remained in Leyte Gulf for the next six weeks then participated in most of the subsequent landings in the Philippines: Ormoc Bay on 6 December, Mindoro Island on 14 December, Lingayen Gulf on 6 January 1945 and Zambales and Subic Bay on 29-31 January, Manila Bay on 13 February, Corregidor on the 14th and continued sweeping in Manila Bay through 19 February.

During the next two and one-half months, Sentry carried out various local sweeps in support of mop-up operations in the Philippines, at Legaspi, Luzon, on 1 April 1945, and an 8-day sweep in the Sulu Sea off Palawan beginning on 22 April. Between 7 and 18 June 1945, Sentry supported the landings at Brunei Bay, Borneo; and, between 22 June and 15 July, she helped clear the way for the assault at Balikpapan. Sentry's task unit received a Presidential Unit Citation for its service off Borneo between 15 June and 1 July 1945. Sentry departed the Philippines on 8 September 1945 and arrived at Sasebo, Japan, on 20 October. In the following weeks, she swept Japanese minefields in the Ryukyus, the Tsushima Strait, and the Van Diemen Strait.

She sailed from Sasebo on 9 December 1945 for the United States. Arriving at Orange, Texas, on 2 April 1946, she was decommissioned there on 19 June 1946 and placed in reserve. Her classification was changed from AM-299 to MSF-299, effective 7 February 1955. Sentry was struck from the Navy list on 1 February 1962 and transferred to the Republic of Vietnam on 31 August 1962 as Ky Hoa (HQ-09).
