HMS Calder was a Buckley class Captain class frigate during World War II. Named after Admiral Sir Robert Calder, Bt. KCB, who was appointed Captain of the Fleet to Admiral John Jervis in 1796, and saw action at the battle of Cape St Vincent on 14 February 1797.

The Commanding Officers of HMS Calder were Lt Cdr A D White RNR March 1943 and Lt Cdr E Playne RNVR February 1945.


HMS Calder served exclusively with the 4th Escort Group earning battle honours for service in the North Atlantic.

On 26 January 1945 the submarine U-1051 was sunk in the Irish Sea south of the Isle of Man, at position 53°39′N 05°23′W / 53.65°N 5.383°W / 53.65; -5.383 by the frigates HMS Aylmer, HMS Bentinck, HMS Calder and HMS Manners. U-1051 was forced to the surface by the use of depth charges, then a gun battle ensued with U-1051 finally sinking after it had been rammed by HMS Aylmer. This action resulted in the loss of all hands (47) from the crew of U-1051. It entirely clear that the ramming of U-1051 by HMS Aylmer was intentional and that Cdr B.W.Taylor was not removed from command of HMS Aylmer shortly after this incident. For further information please look at the HMS Aylmer article.

On 8 April 1945 the submarine U-774 was sunk in the North Atlantic south-west of Ireland, at position 49°58′N 11°51′W / 49.967°N 11.85°W / 49.967; -11.85 by the frigates HMS Bentinck and HMS Calder. U-774 was attacked by the use of depth charges after its periscope was spotted by a lookout on HMS Calder. This action resulted in loss of all hands (44) aboard U-774.
