Convoy PQ 12
Convoy PQ 12 was an Arctic convoy sent from Great Britain by the Western Allies to aid the Soviet Union during World War II. It sailed in March 1942, reaching Murmansk despite a sortie against it by the German battleship ''Tirpitz''. All ships arrived safely. Ships PQ 12 consisted of 16 ships under the command of Commodore HT Hudson. The Close Escort comprised the minesweeper ''Gossamer'' and five whalers. These were joined on 5 March by the Ocean Escort of two destroyers, ''Oribi'', commanded by Cdr. JEH McBeath who took over as SOE, and ''Offa'', supported by the cruiser ''Kenya''. Distant cover was provided by two Heavy Cover Forces; one comprising the battleship ''Duke of York'' (V. Adm. ATB Curteis commanding), the battlecruiser ''Renown'', and six destroyers, sailing from Reykjavik, and another led by Adm. J Tovey comprising the battleship ''King George V'', the carrier , the cruiser ''Berwick'' and six destroyers, sailing from Scapa Flow. Action PQ 12 saile ...

Arctic Convoys Of World War II
The Arctic convoys of World War II were oceangoing convoys which sailed from the United Kingdom, Iceland, and North America to northern ports in the Soviet Union – primarily Arkhangelsk (Archangel) and Murmansk in Russia. There were 78 convoys between August 1941 and May 1945, sailing via several seas of the Atlantic and Arctic oceans, with two gaps with no sailings between July and September 1942, and March and November 1943. About 1,400 merchant ships delivered essential supplies to the Soviet Union under the Anglo-Soviet agreement and US Lend-Lease program, escorted by ships of the Royal Navy, Royal Canadian Navy, and the U.S. Navy. Eighty-five merchant vessels and 16 Royal Navy warships (two cruisers, six destroyers, eight other escort ships) were lost. Nazi Germany's '' Kriegsmarine'' lost a number of vessels including one battleship, three destroyers, 30 U-boats, and many aircraft. The convoys demonstrated the Allies' commitment to helping the Soviet Union, prior to the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Cruiser
A cruiser is a type of warship. Modern cruisers are generally the largest ships in a fleet after aircraft carriers and amphibious assault ships, and can usually perform several roles. The term "cruiser", which has been in use for several hundred years, has changed its meaning over time. During the Age of Sail, the term ''cruising'' referred to certain kinds of missions—independent scouting, commerce protection, or raiding—fulfilled by frigates or sloops-of-war, which functioned as the ''cruising warships'' of a fleet. In the middle of the 19th century, ''cruiser'' came to be a classification of the ships intended for cruising distant waters, for commerce raiding, and for scouting for the battle fleet. Cruisers came in a wide variety of sizes, from the medium-sized protected cruiser to large armored cruisers that were nearly as big (although not as powerful or as well-armored) as a pre-dreadnought battleship. With the advent of the dreadnought battleship before World W ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
County-class Cruiser
The County class was a class of heavy cruisers built for the Royal Navy in the years between the First and Second World Wars. They were the first post-war cruisers constructed for the Royal Navy and were designed within the limits of the Washington Naval Treaty of 1922. Such ships, with a limit of 10,000 tons, standard displacement and 8-inch calibre main guns may be referred to as "treaty cruisers" (the term "heavy cruiser" was not defined until the London Naval Treaty of 1930). The thirteen Counties were built in the ''Kent'', ''London'' and ''Norfolk'' sub-classes. They were the only 10,000-ton 8-inch gun, or "A", cruisers that the Royal Navy built. The Counties are remembered for their distinctive three-funnel layout and service in all the major naval theatres of the Second World War. To extract more ships from the treaty limits, the navy planned to construct 8,250-ton "B" ships, six of which could be built in place of five Counties. The extra ship that this afforded was ...

Destroyer
In naval terminology, a destroyer is a fast, manoeuvrable, long-endurance warship intended to escort larger vessels in a fleet, convoy or battle group and defend them against powerful short range attackers. They were originally developed in 1885 by Fernando Villaamil for the Spanish NavySmith, Charles Edgar: ''A short history of naval and marine engineering.'' Babcock & Wilcox, ltd. at the University Press, 1937, page 263 as a defense against torpedo boats, and by the time of the Russo-Japanese War in 1904, these "torpedo boat destroyers" (TBDs) were "large, swift, and powerfully armed torpedo boats designed to destroy other torpedo boats". Although the term "destroyer" had been used interchangeably with "TBD" and "torpedo boat destroyer" by navies since 1892, the term "torpedo boat destroyer" had been generally shortened to simply "destroyer" by nearly all navies by the First World War. Before World War II, destroyers were light vessels with little endurance for unattended o ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Tribal-class Destroyer (1936)
The Tribal class, or ''Afridi'' class, were 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. As some of the Royal Navy's most modern and powerful escort ships, the Tribal class served with distinction in nearly all theatres of World War II. Only a handful of Royal Navy Tribals survived the war, all of which were subsequently scrapped from hard use, while Commonwealth Tribals continued to serve into the Cold War, serving with distinction in the Korean War. Only one Tribal survives to this day: , whic ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Naval Trawler
Naval trawlers are vessels built along the lines of a fishing trawler but fitted out for naval purposes; they were widely used during the First and Second World Wars. Some—known in the Royal Navy as "Admiralty trawlers"— were purpose-built to naval specifications, others adapted from civilian use. Fishing trawlers were particularly suited for many naval requirements because they were robust vessels designed to work heavy trawls in all types of weather, and had large clear working decks. A minesweeper could be created by replacing the trawl with a mine sweep. Adding depth charge racks on the deck, ASDIC sonar below, and a or gun in the bow equipped the trawler for anti-submarine duties. History Armed trawlers were also used to defend fishing groups from enemy aircraft or submarines. The smallest civilian trawlers were converted to danlayers. Contemporary Some nations still use armed trawlers for fisheries protection and patrol. The Indian Navy used naval trawlers for ...

Convoy Commodore
Convoy commodore also known as commodore, convoys was the title of a civilian put in charge of the good order of the merchant ships in the British convoys used during World War II. Usually the convoy commodore was a retired naval officer or a senior merchant captain drawn from the Royal Naval Reserve. He was aboard one of the merchant ships. The convoy commodore was distinguished from the commander of the convoy's escort, always a naval officer. Description Convoy commodores were based at HMS ''Eaglet'', the Royal Navy's shore establishment at Liverpool. Commodores had a peripatetic role, sailing with each convoy as assigned in a suitable ship. This ship would be the convoy flagship, but remained under the command of its master, the commodore and his team merely taking passage. The commodores were accompanied by a small team of ratings, usually a yeoman and two or three signalers; these teams would stay together and work with the same commodore throughout the campaign, allowin ...
