Admiral of the Fleet John Rushworth Jellicoe, 1st Earl Jellicoe, was a Royal Navy officer. He fought in the Anglo-Egyptian War and the Boxer Rebellion and commanded the Grand Fleet at the Battle of Jutland in May 1916 during the First World War. His handling of the fleet at that battle was controversial. Jellicoe made no serious mistakes and the German High Seas Fleet retreated to port, at a time when defeat would have been catastrophic for Britain, but the public was disappointed that the Royal Navy had not won a more dramatic victory. Jellicoe later served as First Sea Lord, overseeing the expansion of the Naval Staff at the Admiralty and the introduction of convoys, but was relieved at the end of 1917. He also served as the Governor-General of New Zealand in the early 1920s.
The first HMS Montrose was one of eight Admiralty-type destroyer leaders, sometimes known as the Scott class. They were named after figures from Scottish history; Montrose was named for the Graham Dukes of Montrose. She was built during the First World War, but was completed too late for service then. However, she had a long career in the inter-war years and saw extensive service during the Second World War.
The V and W class was an amalgam of six similar classes of destroyer built for the Royal Navy under the War Emergency Programme during the First World War and generally treated as one class. For their time they were among the most powerful and advanced ships of their type in the world, and set the trend for future British designs.
HMS Caroline is a decommissioned C-class light cruiser of the Royal Navy that saw combat service in the First World War and served as an administrative centre in the Second World War. Caroline was launched and commissioned in 1914. At the time of her decommissioning in 2011 she was the second-oldest ship in Royal Navy service, after HMS Victory. She served as a static headquarters and training ship for the Royal Naval Reserve, based in Alexandra Dock, Belfast, Northern Ireland, for the later stages of her career. She was converted into a museum ship. From October 2016 she underwent inspection and repairs to her hull at Harland and Wolff and opened to the public on 1st July 2017 at Alexandra Dock in the Titanic Quarter in Belfast.
The Thornycroft type leader or Shakespeare class were a class of five destroyer leaders designed by John I. Thornycroft & Company and built by them at Woolston, Southampton for the Royal Navy towards the end of World War I. They were named after historical naval leaders. Only Shakespeare and Spenser were completed in time for wartime service. The other three were completed after the war, Broke and Keppel after being towed to Royal dockyards for completion, and two further ships - Saunders and Spragge - were cancelled. The function of a leader was to carry the flag staff of a destroyer flotilla, therefore they were enlarged to carry additional crew, offices and signalling equipment, allowing a fifth gun to be carried. These ships were very similar to the Admiralty type leader, but had broad, slab-sided funnels characteristic of Thornycroft designs.
HMS Mercury was a shore establishment of the Royal Navy, and the site of the Royal Navy Signals School and Combined Signals School. There was also a subsidiary branch, HMS Mercury II.
Aircraft carriers have their origins during the days of World War I. The earliest experiments consisted of fitting temporary "flying off" platforms to the gun turrets of the warships of several nations, notably the United States and the United Kingdom. The first ship to be modified with a permanent flight deck was the battlecruiser HMS Furious, which initially had a single flying-off deck forward of the original superstructure. Subsequently, she was modified with a separate "landing on" deck aft and later with a full flush deck. Other ships, often liners, were modified to have full flush flight decks, HMS Argus being the first to have such modification begun. Those first faltering steps gave little indication of just how important the aircraft carrier was to prove to be. During the inter-war years, Japan, the United Kingdom and the United States built up significant carrier fleets so that by the beginning of World War II, they had 18 carriers between them. The 1940 Battle of Taranto and the 1941 Attack on Pearl Harbor in retrospect showed the world that the aircraft carrier was to be the most important ship in the modern fleet. Today, aircraft carriers are the capital ships of the navies they serve in, and in the case of modern US "supercarriers", they embark an airgroup that is effectively a small air force.
The QF 4-inch gun Mk IV was the main gun on most Royal Navy and British Empire destroyers in World War I. It was introduced in 1911 as a faster-loading light gun successor to the BL 4 inch Mk VIII gun. Of the 1,141 produced, 939 were still available in 1939. Mk XII and Mk XXII variants armed many British interwar and World War II submarines.
The BL 6-inch Mark XII naval gun was a British 45 calibres naval gun which was mounted as primary armament on light cruisers and secondary armament on dreadnought battleships commissioned in the period 1914–1926, and remained in service on many warships until the end of World War II.
HMS Wrestler (D35) was a W class destroyer launched by the Royal Navy in the latter stages of the First World War and active from 1939 to 1944 during the Second World War. She was the first Royal Navy ship to bear that name, and the only one to do so to date.
Two ships of the Royal Navy has borne the name HMS Anzac, after the Australian and New Zealand Army Corps (ANZAC). Another was planned but never completed:
An Escort Group consisted of several small warships organized and trained to operate together providing protection for trade convoys. Escort groups were a World War II tactical innovation in anti-submarine warfare by the Royal Navy to combat the threat of the Kriegsmarine's "wolfpack" tactics. Early escort groups often contained destroyers, sloops, naval trawlers and, later, corvettes of differing specifications lacking the ability to maneuver together as a flotilla of similar warships, but rigorously trained in anti-submarine tactics to use teamwork emphasizing the unique sensors, weapons, speed and turning radius of each ship. The development of these 'escort groups' proved an effective means of defending shipping convoys through the Battle of the Atlantic.
HMS Whitley (L23), ex-Whitby, was a W-class destroyer of the British Royal Navy that saw service in the British campaign in the Baltic Sea against Bolshevik forces during the Russian Civil War and in the early months of World War II.
HMS Vivacious (D36) was a V-class destroyer of the British Royal Navy that saw service in World War I and World War II.
The fifth HMS Valorous, ex-HMS Montrose, was a V-class flotilla leader of the British Royal Navy that saw service in World War I, the Russian Civil War, and World War II.
The second HMS Vanity was a V-class destroyer of the British Royal Navy that saw service in World War I and World War II.
The first HMS Walrus (D24) was a W-class destroyer of the British Royal Navy that saw service in the final months of World War I.
