Mack (naval Architecture)
In naval architecture, a mack is a structure which combines the Mast (ship)#Modern masts, radar masts and the funnel (ship), exhaust stack of a surface ship, thereby saving the upper deck space used for separate funnels and the increasingly large tripod masts used to carry heavy radar aerials. The word is a composite (portmanteau) of "mast" and "stack". It is a common design feature on post-WWII warships, (e.g. the rebuilt Baltimore class cruisers), and on some cruise ships. The Marine Nationale used a combined exhaust stack and rear director mast on Richelieu class battleships in the late 1930s. The Royal Navy used this design feature on the 1944 Weapon class destroyers, and the subsequent Daring class destroyer (1949), ''Daring''s, and in the diesel-engined Leopard class frigate, Type 41 "Cat" class and Salisbury class frigate, Type 61 "Cathedral" class frigates of the 1950s. It provided unbalanced and unattractive designs, which led to a reversion to separate masts and funnel ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

3 (three) is a number, numeral (linguistics), numeral and numerical digit, digit. It is the natural number following 2 and preceding 4, and is the smallest odd prime number and the only prime preceding a square number. It has religious or cultural significance in many societies. Evolution of the Arabic digit The use of three lines to denote the number 3 occurred in many writing systems, including some (like Roman and Chinese numerals) that are still in use. That was also the original representation of 3 in the Brahmic numerals, Brahmic (Indian) numerical notation, its earliest forms aligned vertically. However, during the Gupta Empire the sign was modified by the addition of a curve on each line. The Nāgarī script rotated the lines clockwise, so they appeared horizontally, and ended each line with a short downward stroke on the right. In cursive script, the three strokes were eventually connected to form a glyph resembling a with an additional stroke at the bottom: ३. ...

Leopard Class Frigate
The Type 41 or ''Leopard'' class were a class of anti-aircraft defence frigates built for the Royal Navy (4 ships) and Indian Navy (3 ships) in the 1950s.Purvis, M.K., 'Post War RN Frigate and Guided Missile Destroyer Design 1944-1969', Transactions, Royal Institution of Naval Architects (RINA), 1974Marriott, Leo, 'Royal Navy Frigates Since 1945', Second Edition, , Published by Ian Allan Ltd (Surrey, UK), 1990 The Type 41, together with the Type 61 variant introduced diesel propulsion into the Royal Navy, the perceived benefits being long range, low fuel use, reduced crew (especially skilled artificers), and reduced complexity. Although successful, improvements in traditional steam turbine technology erased the fuel economy advantage of the diesel powerplants and led to production being curtailed in favour of the Type 12 frigate, which was similar in overall design. Design These ships were designed to provide anti-aircraft escorts to convoys and amphibious groups and act as ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Daring Class Destroyer (1949)
The ''Daring'' class was a class of eleven destroyers built for the Royal Navy (RN) and Royal Australian Navy (RAN). Constructed after World War II, and entering service during the 1950s, eight ships were constructed for the RN, and three ships for the RAN. Two of the RN destroyers were subsequently sold to and served in the Peruvian Navy (MGP). A further eight ships were planned for the RN but were cancelled before construction commenced, while a fourth RAN vessel was begun but was cancelled before launch and broken up on the slipway. The ''Daring''-class ships were both the largest and most heavily armed ships serving in Commonwealth navies to be classified as destroyers. They were intended to fill some of the duties of cruisers, which post WW2 were considered both expensive and obsolete by naval planners, and were briefly officially considered a hybrid type (Darings) before being rated as destroyers. They were also the last destroyers of the RN and RAN to possess guns as ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Weapon Class Destroyer
The Weapon class was a class of destroyers built for the British Royal Navy towards the end of World War II. They were the smaller counterpart to the (which followed them) and were the first new destroyer designs for the Royal Navy since the Second World War ''Emergency Programme''. 20 ships were planned, of which only 13 were laid down and 7 were launched, but the cessation of hostilities resulted in only 4 being completed for service. Two of the ships had been previously ordered (as ''Celt'' and ''Centaur'') as part of the planned , or 15th Emergency flotilla, of 1944, but the orders were changed to the new design. Design The Weapon class were an intermediate size built to take advantage of slipways that were too small to be used to build Battle-class destroyers.Brown ''Nelson to Vanguard'' 2000 Chatham Publishing p94 The hull length was not much increased over the ''War Emergency Programme'' design, but beam and draught were increased to allow for a displacement increase ...

Royal Navy
The Royal Navy (RN) is the United Kingdom's naval warfare force. Although warships were used by English and Scottish kings from the early medieval period, the first major maritime engagements were fought in the Hundred Years' War against France. The modern Royal Navy traces its origins to the early 16th century; the oldest of the UK's armed services, it is consequently known as the Senior Service. From the middle decades of the 17th century, and through the 18th century, the Royal Navy vied with the Dutch Navy and later with the French Navy for maritime supremacy. From the mid 18th century, it was the world's most powerful navy until the Second World War. The Royal Navy played a key part in establishing and defending the British Empire, and four Imperial fortress colonies and a string of imperial bases and coaling stations secured the Royal Navy's ability to assert naval superiority globally. Owing to this historical prominence, it is common, even among non-Britons, to ref ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Richelieu Class Battleship
The ''Richelieu'' class were fast battleships built for the French Navy between the 1930s and 1950s. Initially two ships were ordered in 1935 in response to Italian orders for the s the previous year. The ''Richelieu''s were based on the preceding , but scaled up to accommodate more powerful guns and armor to protect them from guns of the same caliber. To keep the ships within the displacement limits imposed by the Washington Naval Treaty, they featured the same concentrated arrangement as the ''Dunkerque''s for the main battery: two quadruple gun turrets placed forward. They also incorporated new, more compact boilers that allowed for a shorter hull (which required less heavy armor) for the desired top speed. After Germany ordered two s, France responded with another pair of ''Richelieu''s, to be built to modified designs. The first, ''Clemenceau'', would have received modified secondary and anti-aircraft batteries, while ''Gascogne'' would have had had her superfiring main b ...

Marine Nationale
The French Navy (french: Marine nationale, lit=National Navy), informally , is the maritime arm of the French Armed Forces and one of the five military service branches of France. It is among the largest and most powerful naval forces in the world, ranking seventh in combined fleet tonnage and fifth in number of naval vessels. The French Navy is one of eight naval forces currently operating fixed-wing aircraft carriers,Along with the U.S., U.K., China, Russia, Italy, India and Spain with its flagship being the only nuclear-powered aircraft carrier outside the United States Navy, and one of two non-American vessels to use catapults to launch aircraft. Founded in the 17th century, the French Navy is one of the oldest navies still in continual service, with precursors dating back to the Middle Ages. It has taken part in key events in French history, including the Napoleonic Wars and both world wars, and played a critical role in establishing and securing the French colonial em ...

Cruise Ships
Cruise ships are large passenger ships used mainly for vacationing. Unlike ocean liners, which are used for transport, cruise ships typically embark on round-trip voyages to various ports-of-call, where passengers may go on tours known as "shore excursions". On "cruises to nowhere" or "nowhere voyages", cruise ships make two- to three-night round trips without visiting any ports of call.Compare: Modern cruise ships tend to have less hull strength, speed, and agility compared to ocean liners. However, they have added amenities to cater to water tourists, with recent vessels being described as "balcony-laden floating condominiums". As of December 2018, there were 314 cruise ships operating worldwide, with a combined capacity of 537,000 passengers. Cruising has become a major part of the tourism industry, with an estimated market of $29.4 billion per year, and over 19 million passengers carried worldwide annually . The industry's rapid growth saw nine or more newl ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Naval Architecture
Naval architecture, or naval engineering, is an engineering discipline incorporating elements of mechanical, electrical, electronic, software and safety engineering as applied to the engineering design process, shipbuilding, maintenance, and operation of marine vessels and structures. Naval architecture involves basic and applied research, design, development, design evaluation (classification) and calculations during all stages of the life of a marine vehicle. Preliminary design of the vessel, its detailed design, construction, trials, operation and maintenance, launching and dry-docking are the main activities involved. Ship design calculations are also required for ships being modified (by means of conversion, rebuilding, modernization, or repair). Naval architecture also involves formulation of safety regulations and damage-control rules and the approval and certification of ship designs to meet statutory and non-statutory requirements.

Baltimore Class Cruiser
The ''Baltimore''-class heavy cruisers were a large class of heavy cruisers in the United States Navy commissioned during and shortly after World War II.The ''Baltimore''-class were the largest cruisers of World War II by tonnage. Fourteen ''Baltimore''s were completed, more than any other class of heavy cruiser (the British had 15 vessels planned, but only 13 completed), along with three ships of the sub-class. The ''Baltimores'' also were the first cruisers in the US Navy to be designed without the limitations of the London Naval Treaty. Fast and heavily armed, the ''Baltimore'' cruisers were mainly used in World War II to protect the fast aircraft carriers in battle groups from air attack. Additionally, their main guns and secondary guns were regularly used to bombard land targets in support of amphibious landings. After the war, only six ''Baltimore''s (''St. Paul'', ''Macon'', ''Toledo'', ''Columbus'', ''Bremerton'', and ''Helena'') and two ''Oregon City''-class shi ...

Warship
A warship or combatant ship is a naval ship that is built and primarily intended for naval warfare. Usually they belong to the armed forces of a state. As well as being armed, warships are designed to withstand damage and are usually faster and more maneuverable than merchant ships. Unlike a merchant ship, which carries cargo, a warship typically carries only weapons, ammunition and supplies for its crew. Warships usually belong to a navy, though they have also been operated by individuals, cooperatives and corporations. In wartime, the distinction between warships and merchant ships is often blurred. In war, merchant ships are often armed and used as auxiliary warships, such as the Q-ships of the First World War and the armed merchant cruisers of the Second World War. Until the 17th century it was common for merchant ships to be pressed into naval service and not unusual for more than half a fleet to be composed of merchant ships. Until the threat of piracy subsided in the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
