HMS Vanoc (H33)
HMS ''Vanoc'' was a British V and W-class destroyer, V-class destroyer, launched in 1917. The ship saw service in both the First World War, First and Second World Wars. During the First World War, ''Vanoc'' served as part of two destroyer flotillas, undertaking minelayer and convoy escort roles. In 1919, the destroyer took part in British operations in the British campaign in the Baltic (1918–19), Baltic as part of Allied efforts to intervene in the Russian Civil War. During the Second World War, ''Vanoc'' was involved in evacuation efforts to remove troops from Norway and France, and was utilised as a convoy escort, protecting convoys from German U-boats. In this role, ''Vanoc'' sank a German submarine, in March 1941 in the Atlantic, and assisted in the destruction of another, . Three years later, ''Vanoc'' was involved in sinking ''German submarine U-392, U-392'' in the Straits of Gibraltar in concert with a British frigate and several US anti-submarine aircraft.

Pennant Number
In the Royal Navy and other navies of Europe and the Commonwealth of Nations, ships are identified by pennant number (an internationalisation of ''pendant number'', which it was called before 1948). Historically, naval ships flew a flag that identified a flotilla or type of vessel. For example, the Royal Navy used a red burgee for torpedo boats and a pennant with an H for torpedo boat destroyers. Adding a number to the type-identifying flag uniquely identified each ship. In the current system, a letter prefix, called a ''flag superior'', identifies the type of ship, and numerical suffix, called a flag inferior, uniquely identifies an individual ship. Not all pennant numbers have a flag superior. Royal Navy systems The Royal Navy first used pennants to distinguish its ships in 1661 with a proclamation that all of his majesty's ships must fly a union pennant. This distinction was further strengthened by a proclamation in 1674 which forbade merchant vessels from flying any ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Draft (hull)
The draft or draught of a ship is a determined depth of the vessel below the waterline, measured vertically to its hull's lowest—its propellers, or keel, or other reference point. Draft varies according to the loaded condition of the ship. A deeper draft means the ship will have greater vertical depth below the waterline. Draft is used in under keel clearance calculations, where the draft is calculated with the available depth of water (from Electronic navigational charts) to ensure the ship can navigate safely, without grounding. Navigators can determine their draught by calculation or by visual observation (of the ship's painted load lines). Related terminology A ship's draft/draught is the "depth of the vessel below the waterline measured vertically to the lowest part of the hull, propellers, or other reference point". That is, the draft or draught is the maximum depth of any part of the vessel, including appendages such as rudders, propellers and drop keels if de ...

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.

The Bridal Of Triermain
''The Bridal of Triermain'' is a narrative poem in three cantos by Walter Scott, published anonymously in 1813. It is written in a flexible metre of four and three stress lines. Set in Cumberland, it recounts the exploits of a knight as he seeks to rescue a beautiful maiden, Gyneth, the illegitimate daughter of King Arthur, doomed by Merlin 500 years previously to an enchanted sleep inside a magic castle. Background In 1809 Scott included in an article 'The Inferno of Altisidora' for ''The Edinburgh Annual Review'' three short imitations, of Crabbe, Moore, and himself. The last of these was entitled 'The Vision of Triermain' and consisted of an early version of the first eight stanzas of what was to become ''The Bridal of Triermain''. While he was composing '' Rokeby'' in the autumn of 1812 Scott took some time to extend the fragment to three cantos, planning to publish it anonymously to test the critics, especially Francis Jeffrey, though in the event Jeffrey did not review it. ...

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 ...

Sea Mine
A naval mine is a self-contained explosive weapon placed in water to damage or destroy surface ships or submarines. Similar to anti-personnel mine, anti-personnel and other land mines, and unlike purpose launched naval depth charges, they are deposited and left to wait until, depending on their fuzing, they are triggered by the approach of or contact with any vessel. Naval mines can be used offensively, to hamper enemy shipping movements or lock vessels into a harbour; or defensively, to create "safe" zones protecting friendly sea lanes, harbours, and naval assets. Mines allow the minelaying force commander to concentrate warships or defensive assets in mine-free areas giving the adversary three choices: undertake a resource-intensive and time-consuming minesweeping effort, accept the casualties of challenging the minefield, or use the unmined waters where the greatest concentration of enemy firepower will be encountered.

British 21 Inch Torpedo
There have been a number of 21-inch (53.3cm) torpedoes in service with the Royal Navy of the United Kingdom. Torpedoes of 21-inch calibre were the largest torpedoes in common use in the RN. They were used by surface ships and submarines; aircraft used smaller British 18-inch torpedo, 18-inch torpedoes. Mark I The first British 21-inch torpedo came in two lengths, "Short" at , and "Long" at . The explosive charge was of guncotton, increased later to . The torpedoes were first deployed in the field in 1912 and primarily used by the s throughout most of their service during the First World War.

QF 3-inch 20 Cwt
The QF 3-inch 20 cwt anti-aircraft gun became the standard anti-aircraft gun used in the home defence of the United Kingdom against German Zeppelins airships and bombers and on the Western Front in World War I. It was also common on British warships in World War I and submarines in World War II. 20 cwt referred to the weight of the barrel and breech, to differentiate it from other 3-inch guns (1cwt = 1 hundredweight = , hence the barrel and breech together weighed ). While other AA guns also had a bore of , the term ''3-inch'' was only ever used to identify this gun in the World War I era, and hence this is what writers are usually referring to by ''3-inch AA gun''. Design and development The gun was based on a prewar Vickers naval QF gun with modifications specified by the War Office in 1914. These (Mk I) included the introduction of a vertical sliding breech-block to allow semi-automatic operation. When the gun recoiled and ran forward after firing, the motion also opened the ...

Superfiring
Superfiring armament is a naval design technique in which two or more turrets are located one behind the other, with the rear turret located above ("super") the one in front so that it can fire over the first. This configuration meant that both forward and aft turrets could fire at any target within their sector, even when the target was directly ahead of the turrets. History Historically, large surface warships were known by the generic label of battleships, with a further distinction between pre-dreadnoughts and dreadnoughts. The era of technical evolution occurred roughly from 1900 to 1945. Part of the technical evolution was driven by the need to compress as much large-gun firepower into the smallest space possible. In early designs, the large-caliber turrets were all located on the same plane firing to one side or the other. In firing ahead or to the rear, usually only the forward-most or rearmost turret could fire, especially at low angles. An early concern was tha ...

QF 4 Inch Mk V Naval Gun
The QF 4 inch Mk V gunMk V = Mark 5. Britain used Roman numerals to denote Marks (models) of ordnance until after World War II. Mark V indicates this was the fifth model of QF 4-inch gun. was a Royal Navy gun of World War I which was adapted on British ordnance terms#HA, HA (i.e. high-angle) mountings to the heavy anti-aircraft role both at sea and on land, and was also used as a coast defence gun. Service Naval service This QF gun was introduced to provide a higher rate of fire than the BL 4 inch naval gun Mk VII, BL 4 inch Mk VII. It first appeared in 1914 as secondary armament on s, was soon adapted to a high-angle anti-aircraft role. It was typically used on cruisers and heavier ships, although s of 1917 also mounted the gun. Mk V was superseded by the QF 4 inch Mk XVI as the HA (i.e. anti-aircraft) gun on new warships in the 1930s, but it continued to serve on many ships such as destroyers, light and heavy cruisers in World War II.

Sea Trials
A sea trial or trial trip is the testing phase of a watercraft (including boats, ships, and submarines). It is also referred to as a " shakedown cruise" by many naval personnel. It is usually the last phase of construction and takes place on open water, and it can last from a few hours to many days. Sea trials are conducted to measure a vessel's performance and general seaworthiness. Testing of a vessel's speed, maneuverability, equipment and safety features are usually conducted. Usually in attendance are technical representatives from the builder (and from builders of major systems), governing and certification officials, and representatives of the owners. Successful sea trials subsequently lead to a vessel's certification for commissioning and acceptance by its owner. Although sea trials are commonly thought to be conducted only on new-built vessels (referred by shipbuilders as 'builders trials'), they are regularly conducted on commissioned vessels as well.
