Convoy SC 42
Convoy SC 42 was the 42nd of the numbered series of World War II Slow Convoys of merchant ships from Sydney, Cape Breton Island to Liverpool. SC 42 was attacked over a three night period in September 1941, losing 16 ships sunk and 4 damaged. This was the worst Allied loss following the attack on convoy SC 7 the previous year. Two attacking U-boats were destroyed. Background Sixty-five ships departed Sydney (Nova Scotia) on 30 August 1941 under local escort, bound for Liverpool. The convoy commodore was Rear Admiral WB Mackenzie in ''Everleigh''. A week later, they were met just east of the Strait of Belle Isle by the Canadian 24th Escort Group consisting of the (Lt Cdr JC Hibbard, senior officer) with s , , and .Rohwer & Hummelchen 1992 p.82 Corvettes and were conducting training exercises in the convoy path at the direction of Commander James D. Prentice, RCN, and were prepared to reinforce the escort as the convoy entered an area where U-boats were known to be waiting ...

World War II
World War II or the Second World War, often abbreviated as WWII or WW2, was a world war that lasted from 1939 to 1945. It involved the vast majority of the world's countries—including all of the great powers—forming two opposing military alliances: the Allies and the Axis powers. World War II was a total war that directly involved more than 100 million personnel from more than 30 countries. The major participants in the war threw their entire economic, industrial, and scientific capabilities behind the war effort, blurring the distinction between civilian and military resources. Aircraft played a major role in the conflict, enabling the strategic bombing of population centres and deploying the only two nuclear weapons ever used in war. World War II was by far the deadliest conflict in human history; it resulted in 70 to 85 million fatalities, mostly among civilians. Tens of millions died due to genocides (including the Holocaust), starvation, ma ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Tanker (ship)
A tanker (or tank ship or tankship) is a ship designed to transport or store liquids or gases in bulk. Major types of tankship include the oil tanker, the chemical tanker, and gas carrier. Tankers also carry commodities such as vegetable oils, molasses and wine. In the United States Navy and Military Sealift Command, a tanker used to refuel other ships is called an oiler (or replenishment oiler if it can also supply dry stores) but many other navies use the terms tanker and replenishment tanker. Tankers were first developed in the late 19th century as iron and steel hulls and pumping systems were developed. As of 2005, there were just over 4,000 tankers and supertankers or greater operating worldwide. Description Tankers can range in size of capacity from several hundred tons, which includes vessels for servicing small harbours and coastal settlements, to several hundred thousand tons, for long-range haulage. Besides ocean- or seagoing tankers there are also specialized ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
German Type VII Submarine
Type VII U-boats were the most common type of German World War II U-boat. 703 boats were built by the end of the war. The lone surviving example, , is on display at the Laboe Naval Memorial located in Laboe, Schleswig-Holstein, Germany. Conception and production The Type VII was based on earlier German submarine designs going back to the World War I Type UB III and especially the cancelled Type UG. The type UG was designed through the Dutch dummy company ''NV Ingenieurskantoor voor Scheepsbouw Den Haag'' (I.v.S) to circumvent the limitations of the Treaty of Versailles, and was built by foreign shipyards. The Finnish ''Vetehinen'' class and Spanish Type E-1 also provided some of the basis for the Type VII design. These designs led to the Type VII along with Type I, the latter being built in AG Weser shipyard in Bremen, Germany. The production of Type I was stopped after only two boats; the reasons for this are not certain. The design of the Type I was further used in ...

German Type IX Submarine
The Type IX U-boat was designed by Nazi Germany's ''Kriegsmarine'' in 1935 and 1936 as a large ocean-going submarine for sustained operations far from the home support facilities. Type IX boats were briefly used for patrols off the eastern United States in an attempt to disrupt the stream of troops and supplies bound for Europe. It was derived from the Type IA, and appeared in various sub-types. Type IXs had six torpedo tubes; four at the bow and two at the stern. They carried six reloads internally and had five external torpedo containers (three at the stern and two at the bow) which stored ten additional torpedoes. The total of 22 torpedoes allowed U-boat commanders to follow a convoy and strike night after night. Some of the IXC boats were fitted for mine operations; as mine-layers they could carry 44 TMA or 66 TMB mines. Secondary armament was provided by one deck gun with 180 rounds. Anti-aircraft armament differed throughout the war. They had two periscopes in the towe ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

RAF Coastal Command
RAF Coastal Command was a formation within the Royal Air Force (RAF). It was founded in 1936, when the RAF was restructured into Fighter, Bomber and Coastal Commands and played an important role during the Second World War. Maritime Aviation had been neglected in the inter-war period, due to disagreements between the Royal Navy (RN) and RAF over the ownership, roles and investment in maritime air power. The Admiralty's main concern until 1937 was the return of the Fleet Air Arm to the Royal Navy while the RAF prioritised the development of a bombing force to provide a deterrent. Coastal Command was referred to as the "Cinderella Service" by A V Alexander, the First Lord of the Admiralty in November 1940. Soon after RAF Coastal Area was elevated to Coastal Command, its headquarters moved from Lee-on-Solent to Northwood in northwest London. During the Second World War, Coastal Command's most important contribution was the protection of Allied convoys from attacks by the Germ ...

S-class Destroyer (1917)
The S class (initially known as the Modified ''Trenchant'' classMarch, ''op. cit.'' p.215.) was a class of 67 destroyers ordered for the Royal Navy in 1917 under the 11th and 12th Emergency War Programmes. They saw active service in the last months of the First World War and in the Russian and Irish Civil Wars during the early 1920s. Most were relegated to the reserve by the mid-1920s and subsequently scrapped under the terms of the London Naval Treaty. Eleven survivors saw much action during the Second World War. Background In early 1917, the First World War had been going on for two and a half years. Despite the disappointing outcome of the Battle of Jutland the previous year, the British Grand Fleet, consisting of battleships, cruisers, and destroyers and based in northern Scotland, was successfully confining the German surface navy to the German Bight, while enforcing a blockade of German maritime trade with the wider world. In southern North Sea, the Harwich Force ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
V And W-class Destroyer
The V and W class was an amalgam of six similar classes of destroyer built for the Royal Navy under the 9th, 10th, 13th and 14th of fourteen War Emergency Programmes 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. They arrived in time to see service in the First World War. During the interwar period these ships formed the backbone of the Royal Navy's destroyer flotillas until gradually replaced by new construction; by the mid-1930s most had been displaced to the reserve fleet. Most ships survived to make an extensive contribution to the Second World War effort, in the vital role of convoy escort, freeing up more modern ships for fleet action. History The V and W class were the ultimate evolution of British destroyer design in the First World War, embodying the improvements of their predecessors as well as new technol ...

Flotilla Leader
A flotilla leader was a warship of late 19th century and early 20th century navies suitable for commanding a flotilla of destroyers or other small warships, typically a small cruiser or a large destroyer (known as a destroyer leader). The flotilla leader provided space, equipment and staff for the flotilla commodore (who typically held the rank of captain), including a wireless room, senior engineering and gunnery officers, and administrative staff to support the officers. Originally, older light or scout cruisers were often used, but in the early 1900s, the rapidly increasing speed of new destroyer designs meant that such vessels could no longer keep pace with their charges. Accordingly, large destroyer designs were produced for use as leaders. As destroyers changed from specialized anti-torpedo boat vessels that operated in squadrons to larger multi-purpose ships that operated alone or as leaders of groups of smaller vessels, and as command and control techniques improved (and ...
