Hunter-Killers
"Croatan sailed from San Diego, California on 2 July 1943, and arrived at Norfolk, Virginia on 19 July.
As the nucleus for a hunter-killer group, she sailed on 5 August for antisubmarine operations in the Atlantic covering the movement of convoys."
From 17 October-29 December 1943, Croatan made two voyages to Casablanca ferrying aircraft and plane crews for the North African operations. After another antisubmarine patrol from 14 January-27 February 1944, she took part in tests with the Naval Research Laboratory at Annapolis, Maryland. From 24 March-11 May, Croatan made a most successful patrol.
On 7 April, her planes marked out the German submarine U-856, which was sunk by her escorts Champlin and Huse at 40°18′N 62°22′W.
On the night of 25–26 April, her four escorts joined in sinking U-488 at 17°54′N 38°05′W. She was also successful in her patrol from 2 June-22 July.
On 10 June, Croatan's planes and escorts Frost, Huse, and Inch attacked U-490 and remained in constant contact with it, forcing it to surface the next day. Sixty survivors, including the commanding officer, were rescued before the submarine sank from scuttling charges at 42°47′N 40°08′W.
Aircraft and escorts Frost and Inch combined again to sink U-154 on 3 July, at 34°00′N 19°30′W."
