HMS Rothesay (F107)

HMS ''Rothesay'' was the lead ship of the ''Rothesay'' or Type 12M class of anti-submarine frigates of the British Royal Navy. She was commissioned in 1960 and scrapped in 1988.

Design

The ''Rothesay''-class was an improved version of the anti-submarine frigate, with nine ''Rothesay''s ordered in the 1954–55 shipbuilding programme for the Royal Navy to supplement the six ''Whitby''s.

''Rothesay'' was long overall and between perpendiculars, with a beam of and a draught of . The ''Rothesay''s were powered by the same Y-100 machinery used by the ''Whitby'' class. Two Babcock & Wilcox water-tube boilers fed steam at and to two sets of geared steam turbines which drove two propeller shafts, fitted with large ( diameter) slow-turning propellers. The machinery was rated at , giving a speed of . Crew was about 212 officers and men.

A twin 4.5-inch (113 mm) Mark 6 gun mount was fitted forward, with 350 rounds of ammunition carried. It was originally intended to fit a twin 40 mm L/70 Bofors anti-aircraft mount aft, but in 1957, while ''Rothesay'' was still under construction, it was decided to fit the Seacat anti-aircraft missile instead. Seacat was not yet ready, and ''Rothesay'' was completed with a twin Mark 5 L/60 40 mm Bofors mount aft as a temporary anti-aircraft armament. The design anti-submarine armament consisted of twelve 21-inch torpedo-tubes (eight fixed and two twin rotating mounts) for Mark 20E Bidder homing anti-submarine torpedoes, backed up by two Limbo anti-submarine mortars fitted aft. The Bidder homing torpedoes proved unsuccessful, however, being too slow to catch modern submarines, and the torpedo tubes were soon removed.

The ship was fitted with a Type 293Q surface/air search radar on the foremast, with a Type 277 height-finding radar on a short mast forward of the foremast. A Mark 6M fire control system (including a Type 275 radar) for the 4.5-inch guns was mounted above the ship's bridge, while a Type 974 navigation radar was also fitted. The ship's sonar fit consisted of Type 174 search, Type 170 fire control sonar for Limbo and a Type 162 sonar for classifying targets on the sea floor.

''Rothesay'' was laid down at Yarrow's Scotstoun dockyard on 6 November 1956, was launched on 9 December 1957 by Audrey Douglas-Hamilton, wife of George Douglas-Hamilton, the First Lord of the Admiralty, and completed on 23 April 1960.

Modernisation

From 1966 to 1968 ''Rothesay'' underwent a major modernisation, which brought the ship close in capacity to the . A hangar and flight deck was added aft to allow a Westland Wasp helicopter to be operated, at the expense of one of the Limbo anti-submarine mortars, while a Seacat launcher and the associated GWS20 director were mounted on the hangar roof. Two 20-mm cannons were added either side of the ship's bridge. A MRS3 fire control system replaced the Mark 6M, and its integral Type 903 radar allowed the Type 277 height finder radar to be removed. A Type 993 surface/air-search radar replaced the existing Type 293Q radar, while the ship's defences were enhanced by the addition of the Corvus chaff rocket dispenser.

History

In the spring/summer of 1961 ''Rothesay'' was in Halifax, Nova Scotia and was intending to make courtesy calls at ports on the eastern seaboard of the United States but was instead diverted to Bermuda, location of the Royal Naval Dockyard that had been reduced to a naval station in 1951 (and headquarters of the America and West Indies Station until 1956, when the position of the Commander-in-Chief was abolished, though the station frigates remained based there), where she was to stay ready to protect British interests in Cuba. On 21 March 1962 she accidentally rammed the Turkish in the western Mediterranean (off Gibraltar) during the NATO exercise "Dawn Breeze". Between 1962 and 1963 she was commanded by Captain B C Godfrey Place.

During two visits to the West Indies (7 months and 11 months) she was at Nassau, Bahamas and filmed for three days to get a 30-second showing in the James Bond film '' Thunderball''. A sheet of canvas with a "0" was placed over the "F1" of her pennant number (F107) to read 007. Sean Connery and Claudine Auger came on board. On 14/15 January 1966 ''Rothesay'' rescued 134 Haitian refugees, who had been attempting to reach the Bahamas in a long fishing boat but had run aground on an uninhabited island.

Between 1966 and 1968 ''Rothesay'' was refitted in Rosyth. Among the improvements the 40 mm gun was replaced with Seacat missile system, radar and communication equipment was updated, accommodation improved and perhaps most significantly a helicopter flight deck and hangar were added. Although this required the removal of one of the two triple barrelled anti-submarine mortars, it allowed the ''Rothesay'' class to carry the Westland Wasp helicopter, which was a huge asset for anti-submarine operations. This modernisation was a vast improvement over the ''Whitby'' class and brought the ''Rothesay'' class up to the standard of the succeeding .

On 19 March 1969, together with , they landed 315 men of The Parachute Regiment on Anguilla to restore order after the islanders objected to being placed under the government of Saint Kitts. In 1971, she was present at Portsmouth Navy Days.

In April 1970 ''Rothesay'' was one of several Royal Navy vessels that were stationed for a possible tertiary splashdown recovery of Apollo 13 in a position just south of Rio de Janeiro, Brazil.

In 1973 ''Rothesay'' undertook Cod War fishery protection patrols.

She attended the 1977 Silver Jubilee Fleet Review with sister ships , and . At this time, she was part of the 8th Frigate Squadron.Official Souvenir Programme, 1977. ''Silver Jubilee Fleet Review'', HMSO

At the start of the Falklands War, ''Rothesay'' was in Rosyth under repair after she hit a sea wall in Esbjerg, Denmark. During the 1982 conflict, ''Rothesay'' was stationed in the Caribbean.

There were plans to withdraw the ship from service in 1983, but these were abandoned and instead in 1985 she underwent a refit in preparation for her new role in the Dartmouth Training Squadron. She served in this role until she was paid off on 13 March 1988. During her many years of service, she clocked up over 800,000 miles. She was sold to Spain and was broken up at Santander in 1988.
