The fighting capability of the Loch class was a great jump forward, being based around the new Squid

ahead-throwing A/S mortar. Previously, escorts had attacked with depth charges, requiring the attacking vessel to pass over the submerged submarine and drop warheads over the stern. Consequently, the ahead-looking ASDIC (sonar) set lost contact at the vital moment before the weapons were launched, allowing a skilled submarine commander to take successful evasive action. Squid, however, lobbed three 12 inches (304.8 mm), 390 pound warheads up to 600 yards (548.6 m) ahead of the launching vessel falling in a triangular pattern with sides of 40 yards (36.6 m). As the clockwork fuses detonated the warheads at a depth determined by the ships' ASDIC set, the Squid therefore attacked in full ASDIC contact for greater accuracy and lethality. Two mortars were carried, with the bombs set to explode at different depths in order to create a convergent pressure wave to crush the hull of a submarine. The first successful "kill" was by Loch Killin on 31 July 1944, sinking U-333

carriage was reduced to only 15, with a single rack and a pair of throwers being carried at the stern, resulting in a clear quarterdeck compared to the eight throwers, two racks and stowage for 100 plus charges in the Rivers.
The weapons outfit was completed with a single QF 4 inches (101.6 mm) Mark V gun forwards. An oversight in the River design had been to place the gun in the favourable position forward on the shelter deck, with the ahead throwing Hedgehog

As with the previous wartime escort designs, mercantile machinery was adopted to speed construction, with a pair of 4 cylinder vertical triple expansion reciprocating engines. Loch Arkaig and Loch Tralaig were fitted with Parsons single reduction steam turbines to establish the feasibility of such an installation, but it was not possible to provide enough sets of turbines for all vessels. One advantage of the use of mercantile machinery was that it was instantly familiar to the mainly reservist and volunteer (RNR

Service
Of the one hundred and ten vessels ordered, twenty-eight were built as frigate, entering service from 1944. Another two - Loch Assynt and Loch Torridon - were converted while building and completed as Coastal Forces Depot Ships, being renamed Derby Haven and Woodbridge Haven. Due to a need in 1944 for a version fitted as anti-aircraft vessels with the British Pacific Fleet, twenty-six units were authorised for completion to a modified design labelled the Bay class frigateBay class frigate

and were renamed. A further fifty-four Loch class vessels were cancelled in 1945.
Of the twenty-eight Loch class frigates completed as such, Loch Achanalt, Loch Alvie and Loch Morlich were transferred to Canada in 1943 but retained their Royal Navy names and were returned after the war; a fourth ship - Loch Fionn - was also earmarked for transfer but was retained by the Royal Navy

In 1953, seven vessels were modernised; Loch Alvie, Loch Fada, Loch Fyne, Loch Insh, Loch Killisport, Loch Lomond and Loch Ruthven.
