The Fiji-class cruisers were a class of eleven light cruisers of the Royal Navy that saw extensive service throughout the Second World War. Each ship of the class was named after a Crown colony or other constituent territory of the British Commonwealth and Empire. The class was also known as the Colony class, or Crown Colony class. Developed as more compact versions of the preceding Town-class cruisers, the last three were built to a slightly modified design and were sometimes also called the Ceylon class.
The Town class consisted of 10 light cruisers built for the Royal Navy during the 1930s. The Towns were designed to the constraints imposed by the London Naval Treaty of 1930. The ships were built in three distinct sub-classes, the Southampton, Gloucester and Edinburgh classes respectively, each sub-class adding on further weaponry.
The Dido class consisted of sixteen light cruisers built for the Royal Navy during World War II. The first group of three ships were commissioned in 1940; the second group and third group were commissioned between 1941 and 1942. A fourth group, also described as the Improved Dido, or the Bellona class, were commissioned between 1943 and 1944. Most members of the class were given names drawn from classical history and legend. The groups differed in armament and for the Bellonas, in function. The Dido class were designed as small trade protection cruisers with five turrets, each with twin 5.25" guns in high angle mountings, far more modern in design than previous light cruiser turrets, offering efficient loading up to 90 degrees elevation to give some dual-purpose capacity. While some damage was experienced initially in extreme North Atlantic conditions, modified handling avoided the problem. The fitting of the three turrets forward in A, B and C positions depended on some use of aluminium in the structure and the lack of aluminium after Dunkirk was one of the reasons for only four turrets being fitted to the first group of three, while the third group had four turrets with twin 4.5" guns. The Bellona's were designed from the start with four turrets with radar-aimed guns and greater light anti-aircraft armament.
The QF 4.5 inch gun has been the standard medium-calibre naval gun used by the Royal Navy as a medium-range weapon capable of use against surface, aircraft and shore bombardment targets since 1938. This article covers the early 45-calibre family of guns up to the 1970s. For the later unrelated 55-calibre Royal Navy gun, see 4.5 inch Mark 8 naval gun. Like all British nominally 4.5 inch naval guns, the QF Mk I has an actual calibre of 4.45 inches (113 mm).
The Allen M. Sumner class was a group of 58 destroyers built by the United States during World War II. Another twelve ships were completed as destroyer minelayers. The class was named for Allen Melancthon Sumner, an officer in the United States Marine Corps. Often referred to as simply the Sumner, this class was distinguished from the previous Fletcher class by their twin 5-inch/38 caliber gun mounts, dual rudders, additional anti-aircraft weapons, and many other advancements. The Allen M. Sumner design was extended 14 feet (4.3 m) amidships to become the Gearing class, which was produced in larger numbers but did not see significant service in World War II.
The Tribal class, or Afridi class, was a class of destroyers built for the Royal Navy, Royal Canadian Navy and Royal Australian Navy that saw service in World War II. Originally conceived during design studies for a light fleet cruiser, the Tribals evolved into fast, powerful destroyers, with greater emphasis on guns over torpedoes than previous destroyers, in response to new designs by Japan, Italy, and Germany. The Tribals were well admired by their crews and the public when they were in service due to their power, often becoming symbols of prestige while in service.
HMS Gurkha was an L-class destroyer in Britain's Royal Navy during World War II. She was originally to be named Larne in line with her class letter. However, after the Tribal-class Gurkha was sunk in April 1940 the officers and men of the Gurkha regiments each subscribed one day's pay to replace her and Larne was renamed before launching.
The Hawkins class consisted of five heavy cruisers built for the Royal Navy during the First World War, although none of them saw service during the war. The first ship to be completed, HMS Vindictive, was renamed from HMS Cavendish and converted into an aircraft carrier while under construction. All ships were named after Elizabethan sea captains. The three ships remaining as cruisers in 1939 served in the Second World War, with Effingham being an early war loss through wreck; Raleigh had been lost in a similar shipwreck on uncharted rocks in 1922. Vindictive, though no longer a cruiser, also served throughout the War. This class formed the basis for the definition of the maximum cruiser type under the Washington Naval Treaty of 1922.
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.
A dual-purpose gun is a naval artillery mounting designed to engage both surface and air targets.
The Abdiel class were a class of six fast minelayers commissioned into the Royal Navy and active during the Second World War. They were also known as the Manxman class and as "mine-laying cruisers". These ships were armed with a wide variety of defensive weapons from 0.5-inch (13 mm) machine guns to the 4-inch (100 mm) main armament. They were also equipped with a wide array of radars, along with their normal complement of mines. They were easily mistaken for destroyers. Half the class was lost through enemy action during the Second World War; the others saw post-war service, and the last example was scrapped in the early 1970s.
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.
The 3"/50 caliber gun in United States naval gun terminology indicates the gun fired a projectile 3 inches (76 mm) in diameter, and the barrel was 50 calibers long. Different guns of this caliber were used by the U.S. Navy and U.S. Coast Guard from 1900 through to 1990 on a variety of combatant and transport ship classes.
The Soldati class were a group of destroyers built for the Regia Marina during World War II. The ships were named after military professions. There were two batches; twelve ships were built in 1938–1939, and a second batch of seven ships were ordered in 1940, although only five were completed.
At the start of World War II, the Royal Navy operated a range of destroyer classes. Some of these were legacies of World War I, some were designed during the inter-war years and the rest were the result of wartime experience and conditions. British-built and -designed vessels were also supplied to and built by allied navies, primarily the Australian and Canadian navies.
HMS Bedouin was a Tribal-class destroyer of the British Royal Navy that saw service in World War II.
The 4.7 inch QF Mark IX and Mark XII were 45-calibre, 4.7-inch (120 mm) naval guns which armed the majority of Royal Navy and Commonwealth destroyers in World War II, and were exported to many countries after World War II as the destroyers they were mounted on were sold off.
The 4.7 inch QF Mark XI was a 50-calibre, 4.7-inch (120 mm) naval gun mounted on Royal Navy (RN) and Allied destroyers during World War II.
HMS Milne was a M-class destroyer of the Royal Navy which served during World War II. She was equipped as a flotilla leader.
HMS Meteor was a M-class destroyer built for the Royal Navy during World War II.
