Now HMS Ameer, she was refitted to Royal Navy requirements, including a lengthened flight deck, the installation of ASDIC (Sonar), the adaptation of fire-fighting and ventilation systems, and the alteration of bomb and torpedo storage to accommodate either American or British ordnance.

HMS Ameer was returned to the United States Navy at Norfolk, Virginia on 17 January 1946 and subsequently sold into merchant service 17 September 1946 as Robin Kirk.
