HMAS Nizam
HMAS ''Nizam'' (G38/D15) was an N-class destroyer of the Royal Australian Navy (RAN). The destroyer, named after Osman Ali Khan, the last Nizam of Hyderabad, was commissioned into the RAN in 1940, although the ship remained the property of the Royal Navy for her entire career. ''Nizam'' spent the early part of her service in the Atlantic, then was reassigned to the Mediterranean, where she was involved in the Crete and Syria-Lebanon Campaigns, the Tobruk Ferry Service, and the Malta Convoys. During 1942, the destroyer was involved in Operation Vigorous and the Madagascar Campaign. The next year saw the ship involved in patrols of the Indian and South Atlantic oceans, searching for German ships and submarines, and rescuing the survivors of U-boat attacks. After returning to Australia for a refit at the end of 1944, ten sailors were washed overboard in February 1945, with none ever seen again. The rest of World War II was spent operating in the Philippines and New Guinea regions ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Osman Ali Khan, Asaf Jah VII
Mir Osman Ali Khan, Asaf Jah VII (5 or 6 April 1886 — 24 February 1967), was the last Nizam (ruler) of the Princely State of Hyderabad, the largest princely state in British India. He ascended the throne on 29 August 1911, at the age of 25 and ruled the Kingdom of Hyderabad between 1911 and 1948, until India annexed it. He was styled as His Exalted Highness-(H.E.H) the Nizam of Hyderabad, and was widely considered as one of the world's wealthiest person of all time. With some estimate placing his wealth at 2% of U.S. GDP, his portrait was on the cover of ''Time magazine'' in 1937. As a semi-autonomous monarch, he had his own mint, printing his own currency, the Hyderabadi rupee, and had a private treasury that was said to contain £100 million in gold and silver bullion, and a further £400 million of jewels (in 2008 terms). The major source of his wealth was the Golconda mines, the only supplier of diamonds in the world at that time. Among them was the Jacob Diamond ...

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 naval gun, 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.

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] |
Ship Commissioning
Ship commissioning is the act or ceremony of placing a ship in active service and may be regarded as a particular application of the general concepts and practices of project commissioning. The term is most commonly applied to placing a warship in active duty with its country's military forces. The ceremonies involved are often rooted in centuries-old naval tradition. Ship naming and launching endow a ship hull with her identity, but many milestones remain before she is completed and considered ready to be designated a commissioned ship. The engineering plant, weapon and electronic systems, galley, and other equipment required to transform the new hull into an operating and habitable warship are installed and tested. The prospective commanding officer, ship's officers, the petty officers, and seamen who will form the crew report for training and familiarization with their new ship. Before commissioning, the new ship undergoes sea trials to identify any deficiencies needing corre ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Nizam Of Hyderabad
The Nizams were the rulers of Hyderabad from the 18th through the 20th century. Nizam of Hyderabad (Niẓām ul-Mulk, also known as Asaf Jah) was the title of the monarch of the Hyderabad State ( divided between the state of Telangana, Marathwada, Marathwada region of Maharashtra and Kalyana-Karnataka region of Karnataka).

Royal Australian Navy
The Royal Australian Navy (RAN) is the principal naval force of the Australian Defence Force (ADF). The professional head of the RAN is Chief of Navy (CN) Vice Admiral Mark Hammond AM, RAN. CN is also jointly responsible to the Minister of Defence (MINDEF) and the Chief of Defence Force (CDF). The Department of Defence as part of the Australian Public Service administers the ADF. Formed in 1901, as the Commonwealth Naval Forces (CNF), through the amalgamation of the colonial navies of Australia following the federation of Australia. Although it was originally intended for local defence, it became increasingly responsible for regional defence as the British Empire started to diminish its influence in the South Pacific. The Royal Australian Navy was initially a green-water navy, and where the Royal Navy provided a blue-water force to the Australian Squadron, which the Australian and New Zealand governments helped to fund, and that was assigned to the Australia Station.

Destroyer
In naval terminology, a destroyer is a fast, manoeuvrable, long-endurance warship intended to escort larger vessels in a fleet, convoy or battle group and defend them against powerful short range attackers. They were originally developed 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 unattended o ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Depth Charge
A depth charge is an anti-submarine warfare (ASW) weapon. It is intended to destroy a submarine by being dropped into the water nearby and detonating, subjecting the target to a powerful and destructive Shock factor, hydraulic shock. Most depth charges use explosive, high explosive charges and a fuze set to detonate the charge, typically at a specific depth. Depth charges can be dropped by ships, 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, during which they were supplemented, and later largely replaced, by anti-submarine homing torpedoes. A depth charge fitted with a nuclear warhead is also known as a "nuclear depth bomb". These were designed to be dropped from a patrol plane or deployed by an anti-submarine missile from a s ...

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 other sizes of torpedo tube have been used: see Torpedo classes and diameters. 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 ...

British 21-inch Torpedo
There have been several British 21-inch (533 mm) torpedoes used by the Royal Navy since their first development just before the First World War. Torpedoes of 21 inch calibre were the largest torpedoes in common use in the RN. They were used by surface ships and submarines rather than aircraft, which 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 gun cotton increased later to . Mark II The Mark II, chiefly used by destroyers, entered service in 1914. Apart from some older British ships, it was used with the old US (destroyers-for-bases deal) Town-class destroyers provided to the UK during the early part of the Second World War. The running speed was reduced from (over 3,000 yards) for better reliability. The Mark II*, an improved Mark II, was used by battleships and battlecruisers. A wet heater design, it could run for at .

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, who 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.
