Commissioned in the US Navy as the USS Amick (DE-168) in 1943, she was mostly assigned at the Atlantic theatre doing escort duties for transatlantic convoys.

[1][3] Remained laid-up in Japan, she was transferred to the Philippine government on 13 September 1976[2] and was sold as Excess Defense Article on 23 December 1978.

As a Philippine Navy ship, she was named RPS Datu Sikatuna (PS-77), and was towed to South Korea for an extensive refit in 1979.

During this period South Korea also turned over 2 of their own ex-USN Cannon class ships to the US Navy in 1977, namely the Kyong Ki (DE-71) /USS Muir (DE-770) and Kang Won (DE-72) / USS Sutton (DE-771).

These were also turned-over by the US to the Philippine government, which were later on cannibalized for use as parts hulk to upgrade and repair the Datu Sikatuna and her sistership Rajah Humabon, and provide both ships with additional guns and improve her machinery.
