ORP Piorun (G65)
ORP ''Piorun'' was an N-class destroyer operated by the Polish Navy in World War II. The word ''piorun'' is Polish for "Thunderbolt". Ordered by the Royal Navy in 1939, the ship was laid down as HMS ''Nerissa'' before being loaned to the Polish in October 1940 while still under construction. In May 1941 ORP ''Piorun'' located the , and drew her fire, while other units of the Royal Navy task force caught up to sink the ''Bismarck''. After World War II, ''Piorun'' was returned to the Royal Navy and recommissioned as HMS ''Noble'' before being scrapped in 1955. Design The eight ships of the N-class were ordered on 15 April 1939. They were a repeat of the J- and K-class destroyers, 16 of which were ordered in 1937. The N-class were long between perpendiculars and overall, with a beam of and a draught of . Displacement was standard and full load. Two Admiralty three-drum boilers fed steam at and to two sets of Parsons single-reduction geared-steam turbines, rated at . ...

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 Mk V was superseded by the QF 4 inch Mk XVI as the HA (i.e. anti-aircraft) gun on new warships in the 1930s, but it continued to serve on many ships such as destroyers, light and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.

Length Overall
Length overall (LOA, o/a, o.a. or oa) is the maximum length of a vessel's hull measured parallel to the waterline. This length is important while docking the ship. It is the most commonly used way of expressing the size of a ship, and is also used for calculating the cost of a marina berth (for example, £2.50 per metre LOA). LOA is usually measured on the hull alone. For sailing ships, this may ''exclude'' the bowsprit and other fittings added to the hull. This is how some racing boats and tall ships use the term LOA. However, other sources may include bowsprits in LOA. Confusingly, LOA has different meanings. "Sparred length", "Total length including bowsprit", "Mooring length" and "LOA including bowsprit" are other expressions that might indicate the full length of a sailing ship. LOD Often used to distinguish between the length of a vessel including projections (e.g. bow sprits, etc.) from the length of the hull itself, the Length on Deck or LOD is often reported. T ...

Length Between Perpendiculars
Length between perpendiculars (often abbreviated as p/p, p.p., pp, LPP, LBP or Length BPP) is the length of a ship along the summer load line from the forward surface of the stem, or main bow perpendicular member, to the after surface of the sternpost, or main stern perpendicular member. When there is no sternpost, the centerline axis of the rudder stock is used as the aft end of the length between perpendiculars. Measuring to the stern post or rudder stock was believed to give a reasonable idea of the ship’s carrying capacity, as it excluded the small, often unusable volume contained in its overhanging ends. On some types of vessels this is, for all practical purposes, a waterline measurement. In a ship with raked stems, naturally that length changes as the draught of the ship changes, therefore it is measured from a defined loaded condition.

Thunderbolt
A thunderbolt or lightning bolt is a symbolic representation of lightning when accompanied by a loud thunderclap. In Indo-European mythology, the thunderbolt was identified with the 'Sky Father'; this association is also found in later Hellenic representations of Zeus and Vedic descriptions of the ''vajra'' wielded by the god Indra. It may have been a symbol of cosmic order, as expressed in the fragment from Heraclitus describing "the Thunderbolt that steers the course of all things". In its original usage the word may also have been a description of the consequences of a close approach between two planetary cosmic bodies, as Plato suggested in '' Timaeus'', or, according to Victor Clube, meteors, though this is not currently the case. As a divine manifestation the thunderbolt has been a powerful symbol throughout history, and has appeared in many mythologies. Drawing from this powerful association, the thunderbolt is often found in military symbolism and semiotic represen ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Polish Language
Polish (, , or simply , ) is a West Slavic languages, West Slavic language of the Lechitic languages, Lechitic subgroup, within the Indo-European languages, Indo-European language family, and is written in the Latin script. It is primarily spoken in Poland and serves as the official language of the country, as well as the language of the Polish diaspora around the world. In 2024, there were over 39.7 million Polish native speakers. It ranks as the sixth-most-spoken among languages of the European Union. Polish is subdivided into regional Dialects of Polish, dialects. It maintains strict T–V distinction pronouns, Honorifics (linguistics), honorifics, and various forms of formalities when addressing individuals. The traditional 32-letter Polish alphabet has nine additions (, , , , , , , , ) to the letters of the basic 26-letter Latin alphabet, while removing three (x, q, v). Those three letters are at times included in an extended 35-letter alphabet. The traditional set compri ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Destroyer
In naval terminology, a destroyer is a fast, maneuverable, long-endurance warship intended to escort larger vessels in a fleet, convoy, or carrier battle group and defend them against a wide range of general threats. They were conceived 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 unatte ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
J, K And N-class Destroyer
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 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 ships were modified throughout their wartime service, particularly their anti-aircraft (AA) guns; they were also fitted with radar. Design history The design was intended as a smaller follow-on from the preceding Tribal class. In a departure from all previous Royal Navy destroyers, the design used a two boiler room layout. This reduced hull length and allowed for a single funnel, both reducing the profile and increasing the arcs of fire of the light anti-aircraft (AA) weapons. It also increased vulnerability, as there were now two adjacent large compartments with the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Depth Charge
A depth charge is an anti-submarine warfare (ASW) weapon designed to destroy submarine A submarine (often shortened to sub) is a watercraft capable of independent operation underwater. (It differs from a submersible, which has more limited underwater capability.) The term "submarine" is also sometimes used historically or infor ...s by detonating in the water near the target and subjecting it to a destructive shock factor, hydraulic shock. Most depth charges use high explosives with a fuze set to detonate the charge, typically at a specific depth from the surface. Depth charges can be dropped by ships (typically fast, agile surface combatants such as destroyers or frigates), patrol aircraft and helicopters. Depth charges were developed during World War I, and were one of the first viable methods of attacking a submarine underwater. They were widely used in World War I and World War II, and remained part of the anti-submarine arsenals of many navies during the Cold War, duri ...

Torpedo Tubes
A torpedo tube is a cylindrical device for launching torpedoes. There are two main types of torpedo tube: underwater tubes fitted to submarines and some surface ships, and deck-mounted units (also referred to as torpedo launchers) installed aboard surface vessels. Deck-mounted torpedo launchers are usually designed for a specific type of torpedo, while submarine torpedo tubes are general-purpose launchers, and are often also capable of deploying mines and cruise missiles. Most modern launchers are standardized on a diameter for light torpedoes (deck mounted aboard ship) or a diameter for heavy torpedoes (underwater tubes), although torpedoes of other classes and diameters have been used. Submarine torpedo tube A submarine torpedo tube is a more complex mechanism than a torpedo tube on a surface ship, because the tube has to accomplish the function of moving the torpedo from the normal atmospheric pressure within the submarine into the sea at the ambient pressure of the water ...

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 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.
