Following shakedown out of San Diego, California, Shackle proceeded to Pearl Harbor. In May, she continued west to Midway Island where she cleared the entrance channel of the wreckage of Macaw (ARS-11). She then returned to Hawaii; and, in late November, took ARD-2H in tow and again headed west. Brief duties at Eniwetok, Guam, and Saipan followed; and, in late January 1945, she commenced preparations for the assault on Iwo Jima.

Okinawa operations edit

A unit of Task Force 51, she arrived in the Volcano Islands on 19 February and remained until 10 March. Having completed over 44 salvage and diving assignments, she then sailed for Ulithi to prepare for the Okinawa campaign. On 27 March, she departed the Carolines for the Ryukyus where, operating from Kerama Retto, she provided assistance to ships on the vulnerable screening stations in the Okinawa area and made repairs and pumped water from damaged ships in preparation for docking them. In May alone, she provided salvage and repair assistance to 21 ships, many of which were kamikaze victims.

Minesweeping the East China Sea edit

On 1 July, Shackle joined Task Group 39.11, a mine-sweeping group; and, during that month, as area "Juneau" in the East China Sea was swept, she combined salvage and mine disposal duties. At the end of the month, she returned to Buckner Bay, where, on 12 August, she witnessed the torpedoing of Pennsylvania and immediately commenced salvage work on the damaged battleship. Three days later, the war ended.

End-of-war activity edit

Shackle remained in the Buckner Bay area until 20 September. She then sailed for Tokyo Bay where, into November, she was employed in clearing the docking area at Yokosuka. On the 27th, she started back across the Pacific Ocean. Salvage duties interrupted her voyage at Wake Island. At the end of December, she arrived at Pearl Harbor; and, in February 1946, continued on to the west coast.

She remained at San Diego, California, until ordered to San Francisco, California, where, on 29 June, she was decommissioned and transferred to the United States Coast Guard as the USCGC Acushnet.

On 23 February 2007 Acushnet was designated as "Queen of the Fleet" being the oldest commissioned cutter in the fleet. This distinction is denoted by gold hull numbers on the bow of the ship.

The ship was decommissioned on 11 March 2011.^[1]
