The County class was a class of British guided missile destroyers, the first such warships built by the Royal Navy. Designed specifically around the Seaslug anti-aircraft missile system, the primary role of these ships was area air defence around the aircraft carrier task force in the nuclear-war environment.
HMS Imperial was one of nine I-class destroyers built for the Royal Navy during the 1930s. She was scuttled by HMS Hotspur in 1941 after she had been crippled by Italian bombers.
The Type 21 frigate, or Amazon-class frigate, was a British Royal Navy general-purpose escort that was designed in the late 1960s, built in the 1970s and served throughout the 1980s into the 1990s.
The Tiger class were a class of three British warships of the 20th century and the last all-gun cruisers of the Royal Navy. Construction of three Minotaur-class cruisers began during World War II but, due to post-war austerity, the Korean War and focus on the Royal Air Force over the surface fleet, the hulls remained unfinished. Against a background of changing priorities and financial constraints, approval to complete them to a modified design was given in November 1954 and the three ships – Tiger, Lion and Blake – entered service from March 1959.
The Type 81, or Tribal class, frigates were ordered and built as sloops to carry out similar duties to the immediate post war improved Black Swan-class sloops and Loch-class frigates in the Persian Gulf. In the mid 1960s the seven Tribals were reclassified as second class general-purpose frigates to maintain frigate numbers. After the British withdrawal from East of Suez in 1971 the Tribals operated in the NATO North Atlantic sphere with the only update the fitting of Seacat missiles to all by 1977, limited by their single propeller and low speed of 24 knots. In 1979–80 age and crew and fuel shortages saw them transferred to the stand-by squadrons; three were reactivated in 1982 during the Falklands War for training and guardship duties in the West Indies.
The Daring class was a class of eleven destroyers built for the Royal Navy (RN) and Royal Australian Navy (RAN). Constructed after World War II, and entering service during the 1950s, eight ships were constructed for the RN, and three ships for the RAN. Two of the RN destroyers were subsequently sold to and served in the Peruvian Navy (MGP). A further eight ships were planned for the RN but were cancelled before construction commenced, while a fourth RAN vessel was begun but was cancelled before launch and broken up on the slipway.
HMS Dido was a Royal Navy (RN) Leander-class frigate. Entering service in 1961, Dido was involved in the Indonesia–Malaysia confrontation, served with NATO's Standing Naval Force Atlantic on several occasions, and was one of the frigates used for the filming of the drama series Warship.
The L and M class was a class of sixteen destroyers which served in the British Royal Navy during World War II. The ships of the class were launched between 1939 and 1942.
The O and P class was a class of destroyers of the British Royal Navy. Ordered in 1939, they were the first ships in the War Emergency Programme, also known as the 1st and 2nd Emergency Flotilla, respectively. They served as convoy escorts in World War II, and some were subsequently converted to fast second-rate anti-submarine frigates in the 1950s.
The C class was a class of 32 destroyers of the Royal Navy that were launched from 1943 to 1945. The class was built in four flotillas of 8 vessels, the "Ca", "Ch", "Co" and "Cr" groups or sub-classes, ordered as the 11th, 12th, 13th and 14th Emergency Flotillas respectively. The sub-class names are derived from the initial 2 letters of the member ships' names, although the "Ca" class were originally ordered with a heterogeneous mix of traditional destroyer names. A fifth flotilla, the "Ce" or 15th Emergency Flotilla, was planned but were cancelled in favour of the Weapon-class destroyers after only the first two ships had been ordered. The pennant numbers were all altered from "R" superior to "D" superior at the close of World War II; this involved some renumbering to avoid duplications.
The I-class destroyers were a group of nine destroyers, including a flotilla leader, built for the Royal Navy during the 1930s. Four similar ships were ordered by the Turkish Navy, of which two were purchased for the Royal Navy, bringing the number of these ships in British service to 11—although three of the original ships had been lost by the time Inconstant and Ithuriel were commissioned. The I-class served in World War II and six were lost, with a seventh ship being written off.
The Type 41 or Leopard class were a class of anti-aircraft defence frigates built for the Royal Navy and Indian Navy in the 1950s. The Type 41, together with the Type 61 variant introduced diesel propulsion into the Royal Navy, the perceived benefits being long range, low fuel use, reduced crew, and reduced complexity.
The Type 61 Salisbury class was a class of the Royal Navy aircraft direction (AD) frigate, built in the 1950s. The purpose of the aircraft direction ships was to provide radar picket duties at some distance from a carrier task force and offer interception guidance to aircraft operating in their area.
HMS Royalist was a Bellona-class light cruiser of the Royal Navy (RN) during the Second World War.
HMS Grenville was the second ship of this name to serve with the Royal Navy in the Second World War. Grenville and seven other U-class destroyers were ordered as part of the Emergency Programme. She was launched at Swan Hunter and Wigham Richardson Ltd., Wallsend-on-Tyne on 12 October 1942 and commissioned on 27 May 1943.
The Type 16 frigates were a class of British anti-submarine frigates of the Royal Navy. They were based on the hulls of World War II-era destroyers that had been rendered obsolete by rapid advances in technology. They were similar in concept to the Type 15 frigate, but were a far more limited design rendered necessary by budget constraints.
The J, K and N class consisted of 24 destroyers built for the Royal Navy beginning in 1938. They were a return to a smaller vessel, with a heavier torpedo armament, after the Tribal class that emphasised guns over torpedoes. The ships were built in three flotillas or groups, each consisting of eight ships with names beginning with "J", "K" and "N". The flag superior of the pennant numbers changed from "F" to "G" in 1940.
HMS Swiftsure was one of three Minotaur-class light cruisers built for the Royal Navy during the Second World War. She was laid down by Vickers Armstrong at Newcastle upon Tyne on 22 September 1941, launched on 4 February 1943 by Lady Wake-Walker and commissioned on 22 June 1944. The first of a new Minotaur class, a development of the later Colony class with extra beam and a fifth twin 4 inch turret. Swiftsure was the last Royal Navy cruiser completed during World War II and was the first British cruiser designed around the concept of an operations room and modern radar, with sensor screens and communications positioned for efficient operation. During her service in the Pacific in 1945, she proved the most efficient anti-aircraft cruiser in the fleet and was the first Royal Navy cruiser with the Type 274 lock-and-follow radar targeting system for her main armament.
HMS Aubrietia (K96) was a Flower-class corvette built for the Royal Navy (RN) from 1941-1946. She was active as a convoy escort in the Atlantic and Mediterranean. In May 1941, Aubrietia sighted and depth charged the German submarine U-110, leading to its capture and the seizure of a German Naval Enigma and its Kurzsignale code book.
HMS Amaranthus (K17) was a Flower-class corvette of the Royal Navy. She took part in the Second World War, being involved in escorting convoys from West Africa to the United Kingdom from May 1941 onwards.
