HMS Mohawk was a Template:Sclass2 of the Royal Navy in service from 1963. She was named after a tribe of Native Americans located in southeast Canada and New York State. Mohawk was scrapped in 1983.

Design and construction

The Tribal-, or Type 81-class, frigates were developed in the mid-1950s as a General Purpose frigate, capable of use in both anti-submarine and anti-aircraft duties in a full-scale war, while serving for Cold War policing duties in peace-time,<ref name="Friedp242">Template:Harvnb</ref><ref name="marp70">Template:Harvnb</ref> in particular to replace the old Template:Sclass2s serving in the Persian Gulf.<ref name="conways p518"/>

The Tribals were Template:Convert long overall and Template:Convert between perpendiculars, with a beam of Template:Convert.<ref name="conways p518">Template:Harvnb</ref><ref name="marp72">Template:Harvnb</ref><ref name="jfs71 p356">Template:Harvnb</ref> The ship's hull had a draught of Template:Convert,<ref name="Friedp322">Template:Harvnb</ref> with the propeller increasing overall draught to Template:Convert.<ref name="jfs71 p356"/> Displacement was Template:Convert standard and Template:Convert full load.<ref name="conways p518"/><ref name="jfs71 p356"/> Propulsion was by a single-shaft Combined steam and gas (COSAG) arrangement, effectively half of the powerplant of the Template:Sclass2s. A single Babcock & Wilcox boiler fed steam at Template:Convert and Template:Convert to a geared steam turbine rated at Template:Convert, which could be supplemented by a Metrovick G-6 gas turbine rated at Template:Convert to reach top speed, with the gas turbine also allowing the ship to get underway quickly in an emergency, without having to wait to raise steam.<ref name="conways p518"/><ref name="Friedp242"/> Speed was about Template:Convert using both steam and gas turbine power,<ref name="conways p518"/><ref name="jfs71 p356"/> and Template:Convert on steam power alone.<ref name="marp70"/>

The ships were fitted with two QF 4.5-in (113 mm) Mark 5 guns, salvaged from scrapped Second World War destroyers, mounted fore and aft. It was intended to fit two Seacat anti-aircraft missile launchers, but these were not ready in time, and Gurkha completed with two 40 mm Bofors guns instead, with Seacat replacing the Bofors guns on refit. For anti-submarine and anti-ship duties, a hangar and flight deck for a single Westland Wasp helicopter was fitted, while a Limbo anti-submarine mortar provided close-in anti-submarine armament.<ref name="conways p518"/><ref name="marp702">Template:Harvnb</ref> Mohawk was fitted with a large Type 965 long range air search radar on a lattice foremast, with a Type 993 short range air/surface target indicating radar and Type 978 navigation radar also fitted. An MRS3 fire control system was carried to direct the 4.5-inch guns.<ref name="marp723">Template:Harvnb</ref> The ship had a sonar suite of Type 177 medium range search sonar, Type 162 bottom search and Type 170 attack sonar.<ref name="marp72"/> The ship had a crew of 253 officers and other ranks.<ref name="conways p518"/><ref name="jfs71 p356"/>

Operational Service

In 1965, Mohawk deployed to the Persian Gulf.<ref>Commissioning Book, HMS Mohawk 1964-1965, Gale and Polden, Portsmouth</ref> She joined the Beira Patrol, intended to enforce an oil blockade of Rhodesia, in 1966. The following year, Mohawk deployed to the West Indies and the Mediterranean, becoming the Gibraltar guardship in 1968. By 1969, Mohawk had returned to the West Indies.Template:Citation needed

Mohawk underwent a conversion to accommodate her planned utilisation as a training ship. The refit entailed the removal of MohawkTemplate:'s aft 4.5-inch gun and the conversion of her hangar to a classroom, but the process was abandoned.<ref name="critp112">Template:Harvnb</ref> In 1973, Mohawk and the destroyer Template:HMS relieved the destroyer Template:HMS and frigate Template:HMS in the Far East Squadron. Mohawk contributed to the Beira Patrol before returning to Britain in 1973. Later that year she embarked on a tour of the Norwegian coast. She was called onto assist in the search for Template:Ship, a fishing vessel that went missing in the Barents Sea.Template:Citation needed

In 1974, Mohawk served in the West Indies and the Mediterranean. In 1977, Mohawk joined Naval On-call Force of the Mediterranean (NAVOCFORMED), a NATO multi-national squadron.Template:Citation needed Later that year, Mohawk formed part of a task force designated "Group 6", led by the cruiser Template:HMS, that toured the Middle and Far East.<ref>Gough, Richard (2003), The Weapon Director, p. 2</ref> During the group's return journey the following year, Mohawk suffered hull damage in the port of Valletta, Malta after slipping her moorings early.Template:Citation needed

In 1979, Mohawk was reduced to the reserve and allocated to the Standby Squadron. After being placed on the disposal list in 1981.<ref>Template:Cite hansard</ref> Mohawk was sold for scrap and broken up at Cairnryan.<ref>Colledge & Warlow (2010), p. 265</ref>
