HMS Aubrietia (K96)
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 , leading to its capture and the seizure of a German Naval Enigma (enigma machine) and its Kurzsignale code book. Design and construction The Flower-class arose as a result of the Royal Navy's realisation in the late 1930s that it had a shortage of escort vessels, particularly coastal escorts for use on the East coast of Britain, as the likelihood of war with Germany increased. To meet this urgent requirement, a design developed based on the whale-catcher ''Southern Pride'' - this design was much more capable than Naval trawlers, but cheaper and quicker to build than the Hunt-class destroyers or sloops that were alternatives for the coastal escort role. The early Flowers, such as ''Aubrietia'' were long overall, at the waterline and between perpen ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Displacement (ship)
The displacement or displacement tonnage of a ship is its weight. As the term indicates, it is measured indirectly, using Archimedes' principle, by first calculating the volume of water displaced by the ship, then converting that value into weight. Traditionally, various measurement rules have been in use, giving various measures in long tons. Today, tonnes are more commonly used. Ship displacement varies by a vessel's degree of load, from its empty weight as designed (known as "lightweight tonnage") to its maximum load. Numerous specific terms are used to describe varying levels of load and trim, detailed below. Ship displacement should not be confused with measurements of volume or capacity typically used for commercial vessels and measured by tonnage: net tonnage and gross tonnage. Calculation The process of determining a vessel's displacement begins with measuring its draft.George, 2005. p. 5. This is accomplished by means of its "draft marks". A merchant vessel has t ...

President Of The United States
The president of the United States (POTUS) is the head of state and head of government of the United States. The president directs the Federal government of the United States#Executive branch, executive branch of the Federal government of the United States, federal government and is the Powers of the president of the United States#Commander-in-chief, commander-in-chief of the United States Armed Forces. The power of the presidency has grown since the first president, George Washington, took office in 1789. While presidential power has ebbed and flowed over time, the presidency has played an increasing role in American political life since the beginning of the 20th century, carrying over into the 21st century with some expansions during the presidencies of Presidency of Franklin D. Roosevelt, Franklin D. Roosevelt and Presidency of George W. Bush, George W. Bush.

Warship Week
Warship Weeks were British National savings campaigns during the Second World War, with the aim of a Royal Navy warship being adopted by a civil community. During the early parts of the war, the Royal Navy not only had lost many capital ships but was facing increasing pressure to provide escorts for convoys in the Atlantic. While there was not a shortage of sailors, ships sunk by enemy action had to be replaced. The equivalent for the British Army was Salute the Soldier Week and the equivalent for the Royal Air Force was Wings for Victory Week. Campaign Local fund-raising A level of savings would be set to raise enough money to provide the cost of building a particular naval ship. The aim was for cities to raise enough to adopt battleships and aircraft carriers, while towns and villages would focus on cruisers and destroyers. Smaller towns and villages would be set a lower figure. Once the target money was saved for the ship, the community would adopt the ship and its crew. ...

Horsforth
Horsforth is a town and civil parishes in England, civil parish in the City of Leeds, West Yorkshire, England, five miles north-west of Leeds city centre. Historically a village within the West Riding of Yorkshire, it had a population of 18,895 at the 2011 Census. It became part of the City of Leeds metropolitan borough in 1974.

Ceremonial Ship Launching
Ceremonial ship launching involves the performing of ceremonies associated with the process of transferring a vessel to the water. It is a nautical tradition in many cultures, dating back millennia, to accompany the physical process with ceremonies which have been observed as public celebration and a solemn blessing, usually but not always, in association with the launch itself. Ship launching imposes stresses on the ship not met during normal operation and in addition to the size and weight of the vessel represents a considerable engineering challenge as well as a public spectacle. The process also involves Sailors' superstitions, many traditions intended to invite good luck, such as baptism#Boats and ships, christening by breaking a sacrificial bottle of champagne over the bow (ship), bow as the ship is named aloud and launched. Methods There are three principal methods of conveying a new ship from building site to water, only two of which are called "launching". The ol ...

Keel Laying
Laying the keel or laying down is the formal recognition of the start of a shipbuilding, ship's construction. It is often marked with a ceremony attended by dignitaries from the shipbuilding company and the ultimate owners of the ship. Keel laying is one of the four specially celebrated events in a ship's life; the others are Ceremonial ship launching, launching, Ship commissioning, commissioning, and Ship decommissioning, decommissioning. Earlier, the event recognized as the keel laying was the initial placement of the central timber making up the backbone of a vessel, called the keel. As steel ships replaced wooden ones, the central timber gave way to a central steel beam. Modern ships are most commonly built in a series of pre-fabricated, complete hull sections rather than around a single keel. The event recognized as the keel laying is the first joining of modular components, or the lowering of the first module into place in the building dock. It is now often called "keel ...

Vickers
Vickers was a British engineering company that existed from 1828 until 1999. It was formed in Sheffield as a steel foundry by Edward Vickers and his father-in-law, and soon became famous for casting church bells. The company went public in 1867, acquired more businesses, and began branching out into military hardware and shipbuilding. In 1911, the company expanded into aircraft manufacture and opened a flying school. They expanded even further into electrical and railway manufacturing, and in 1928 acquired an interest in the Supermarine. Beginning in the 1960s, various parts of the company were nationalised, and in 1999 the rest of the company was acquired by Rolls-Royce plc, which sold the defence arm to Alvis plc. The Vickers name lived on in Alvis Vickers, until the latter was acquired by BAE Systems in 2004 to form BAE Systems Land Systems.

QF 2-pounder Naval Gun
The 2-pounder gun, officially the QF 2-pounder ( QF denoting "quick firing") and universally known as the pom-pom, was a British autocannon, used as an anti-aircraft gun by the Royal Navy.British military of the period traditionally denoted smaller guns in terms of the approximate weight of the standard projectile, rather than by its bore diameter, which in this case was 40 mm. References to 40-mm anti-aircraft guns invariably mean the Bofors gun, while references to 2-pounder anti-aircraft guns mean this gun. The name came from the sound that the original models make when firing. This QF 2-pounder was not the same gun as the Ordnance QF 2-pounder, used by the British Army as an anti-tank gun and a tank gun, although they both fired , projectiles. Predecessors – Boer War and the Great War QF 1 pounder The first gun to be called a pom-pom was the 37 mm Nordenfelt-Maxim or "QF 1-pounder" introduced during the Second Boer War, the smallest artillery piece of that war.
