HMS Malcolm was a Blackwood-class, one of a dozen second-rate anti-submarine frigates built for the Royal Navy in the 1950s.

[1] Malcolm was part of a five-ship group that was deployed to Iceland for fishery protection duties in what became known as the Cod Wars.

Malcolm was refitted at Rosyth from February 1965 until March 1966, when she rejoined the Fishery Patrol Squadron.

Duties included training with submarines while continuing to carry out fishery protection patrols.

The Ministry of Defence decided not to replace Malcolm immediately, probably because the situation had calmed somewhat (1970 was between the first and second Cod Wars).
