[1] For 14 hours on 6 December Loch Insh and Goodall hunted for the German submarine U-775 off Cape Wrath, but the U-boat, which had torpedoed the frigate Bullen and sent her to the bottom, escaped undamaged.

[1] After a refit Loch Insh was recommissioned on 21 September 1950 to serve with 6th Frigate Flotilla, Home Fleet, for exercises and visits.

[1] In April 1952 she was decommissioned and was laid up at Devonport in readiness for a programme of extensive modernisation, of which Loch Insh would be the prototype for the rest of her class.

Recommissioned on 6 September 1954, she completed her sea trials in the Mediterranean, before arriving at Bahrain in December for duty in the Persian Gulf alongside Loch Alvie.

Her primary task was the protection of British tanker shipping, and she carried out a regular routine of patrols and port visits until returning to the UK in August 1955.

In October she joined other Royal Navy ships in the multi-national CENTO "Exercise Midlink" in the Indian Ocean, based at Karachi.

In March 1959 she made East African coast visits and called at Tanga, Mtwara and Zanzibar before returning to Devonport in April.
