HMAS Orion
HMAS ''Orion'' (S 61) was an ''Oberon'' class submarine of the Royal Australian Navy (RAN). One of six submarines ordered by the RAN during the 1960s, ''Orion'', named after the constellation in a break from ship-naming tradition, was built in Scotland and commissioned in 1977. ''Orion'' was one of two Oberon-class submarines designed for intelligence gathering and conducted regular patrols in Soviet, Indian and Chinese waters to gather information regarding enemy capabilities. ''Orion'' was decommissioned in 1996, marked for disposal in 2003, and broken up for scrap in 2006. Several sections of the submarine remain intact as memorials and museum pieces. Design and construction The ''Oberon'' class was based heavily on the preceding ''Porpoise'' class of submarines, with changes made to improve the vessels' hull integrity, sensor systems, and stealth capabilities.Chant, ''A Compedium of Armaments and Military Hardware'', pp. 167–8 Eight submarines were ordered for the RAN, i ...

Characteristics Orion is bordered by Taurus to the northwest, Eridanus to the southwest, Lepus to the south, Monoceros (constellation), Monoceros to the east, and Gemini to the northeast. Covering 594 square degrees, Orion ranks twenty-sixth of the 88 constellations in size. The constellation boundaries, as set by Belgian astronomer Eugène Joseph Delporte, Eugène Delporte in 1930, are defined by a polygon of 26 sides. In the equatorial coordinate system, the right ascension coordinates of these borders lie between and , while the declination coordinates are between and .

Brake Horsepower
Horsepower (hp) is a unit of measurement of power, or the rate at which work is done, usually in reference to the output of engines or motors. There are many different standards and types of horsepower. Two common definitions used today are the mechanical horsepower (or imperial horsepower), which is about 745.7 watts, and the metric horsepower, which is approximately 735.5 watts. The term was adopted in the late 18th century by Scottish engineer James Watt to compare the output of steam engines with the power of draft horses. It was later expanded to include the output power of other types of piston engines, as well as turbines, electric motors and other machinery. The definition of the unit varied among geographical regions. Most countries now use the SI unit watt for measurement of power. With the implementation of the EU Directive 80/181/EEC on 1 January 2010, the use of horsepower in the EU is permitted only as a supplementary unit. History The development of the stea ...

Order Of The British Empire
The Most Excellent Order of the British Empire is a British order of chivalry, rewarding contributions to the arts and sciences, work with charitable and welfare organisations, and public service outside the civil service. It was established on 4 June 1917 by King George V and comprises five classes across both civil and military divisions, the most senior two of which make the recipient either a knight if male or dame if female. There is also the related British Empire Medal, whose recipients are affiliated with, but not members of, the order. Recommendations for appointments to the Order of the British Empire were originally made on the nomination of the United Kingdom, the self-governing Dominions of the Empire (later Commonwealth) and the Viceroy of India. Nominations continue today from Commonwealth countries that participate in recommending British honours. Most Commonwealth countries ceased recommendations for appointments to the Order of the British Empire when they ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cold War
The Cold War is a term commonly used to refer to a period of geopolitical tension between the United States and the Soviet Union and their respective allies, the Western Bloc and the Eastern Bloc. The term '' cold war'' is used because there was no large-scale fighting directly between the two superpowers, but they each supported major regional conflicts known as proxy wars. The conflict was based around the ideological and geopolitical struggle for global influence by these two superpowers, following their temporary alliance and victory against Nazi Germany and Imperial Japan in 1945. Aside from the nuclear arsenal development and conventional military deployment, the struggle for dominance was expressed via indirect means such as psychological warfare, propaganda campaigns, espionage, far-reaching embargoes, rivalry at sports events, and technological competitions such as the Space Race. The Western Bloc was led by the United States as well as a number of other First W ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Vladivostok
Vladivostok ( rus, Владивосто́к, a=Владивосток.ogg, p=vɫədʲɪvɐˈstok) is the largest city and the administrative center of Primorsky Krai, Russia.

Libyan Navy
Libyan Navy ( ar, قوات البحرية الليبية) is the branch of the Libyan military responsible for naval warfare. Established in November 1962, Libyan Navy has been headed by Admiral Mansour Bader, Chief of Staff of the Libyan Naval Force. Before the Libyan Civil War it was a fairly typical small navy with a few missile frigates, corvettes and patrol boats to defend the coastline, but with a very limited self-defence capability. The Navy has always been the smallest of Libya's services and has always been dependent on foreign sources for equipment, spare parts, and training. Most of the Gaddafi era fleet was destroyed in 2011. Since the start of the ongoing internal conflict, the Libyan Navy is aligned with the Government of National Accord (GNA), led by the Presidential Council in Tripoli, apart from coastal patrol vessels under the control of the Libyan National Army. History Its first warship was delivered in 1966. These were two s from the UK. Initially the ef ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Passive Underwater Fire Control Feasibility System
Passive Underwater Fire Control Feasibility System (or Study) (PUFFS) was a passive sonar system for submarines. It was designated AN/BQG-4 and was primarily installed on United States Navy conventional submarines built in the 1950s beginning with the , and also those converted to GUPPY III or otherwise modernized in the 1960s. It was also equipped on the nuclear-powered . It was also installed on the USS Thomas Edison (SSBN610) but never achieved operational status. Its transducers can be seen on pictures of the vessel. A version known as "Micropuffs" was fitted on s for the Royal Australian Navy, and as Type 2041 on the ''Upholder''-class for the British Royal Navy. This class still serves in the Royal Canadian Navy as the ''Victoria'' class, where Micropuffs is known as BQG-501. The system was notable for three tall, fin-like domes topside, except on Micropuffs installations. The system was retained on several submarines transferred by the US to foreign navies. It was associated ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
