The Castle-class ships were equipped with a single QF Script error: No such module "convert". Mk XVI gun forward, but their primary weapon was their single three-barrel Squid anti-submarine mortar. This was backed up by one depth charge rail and two throwers for 15 depth charges. The ships were fitted with two twin and a pair of single mounts for Script error: No such module "convert". Oerlikon light AA guns.[2] Provision was made for a further four single mounts if needed. They were equipped with Type 145Q and Type 147B ASDIC sets to detect submarines by reflections from sound waves beamed into the water. A Type 277 search radar and a HF/DF radio direction finder rounded out the Castles' sensor suite.[3]
Construction and career
Alnwick Castle was laid down by George Brown & Co. at their shipyard at Greenock on 12 June 1943 and launched on 23 May 1944. She was completed on 11 November and served as a convoy escort until the end of the Second World War in May 1945.
On 17 February 1945, Alnwick Castle, Lt. Cdr. H.A. Stonehouse R.N.R., and Script error: No such module "WPSHIPS utilities". used depth charges to sink German submarine U-425 near Murmansk.
