Royal Naval Engineers
Royal Naval Engineers as a branch of the Royal Navy, have existed since 1835. Naval engineers are in charge of the management and upkeep of ship-board machinery. Traditionally this included engines, motors, pumps and other mechanical devices, but modern engineers are now responsible for both mechanical systems and high-tech electronics such radar and sonar systems and nuclear-power plants. Ranking When the corps was first created, there were three ranks for engineers: First, second, and third. Over the years this ranking system has changed several times: * 1835 - First, second and third engineer. * 1847 - Inspector of machinery, chief engineer; assistant engineer. * 1886 - Chief inspector and inspector of machinery (r.adm and captain), fleet engineer (cdr), and staff engineer (senior lieutenant). * 1903 - Standard executive rank titles with an "engineer" prefix. * 1956 - "Engineer" prefix and rank branch distinction cloth removed finally making engineers indistinguishable from se ...

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] |
Radar
Radar is a detection system that uses radio waves to determine the distance (''ranging''), angle, and radial velocity of objects relative to the site. It can be used to detect aircraft, ships, spacecraft, guided missiles, motor vehicles, weather formations, and terrain. A radar system consists of a transmitter producing electromagnetic waves in the radio or microwaves domain, a transmitting antenna, a receiving antenna (often the same antenna is used for transmitting and receiving) and a receiver and processor to determine properties of the objects. Radio waves (pulsed or continuous) from the transmitter reflect off the objects and return to the receiver, giving information about the objects' locations and speeds. Radar was developed secretly for military use by several countries in the period before and during World War II. A key development was the cavity magnetron in the United Kingdom, which allowed the creation of relatively small systems with sub-meter resolution. Th ...

Sonar
Sonar (sound navigation and ranging or sonic navigation and ranging) is a technique that uses sound propagation (usually underwater, as in submarine navigation) to navigation, navigate, measure distances (ranging), communicate with or detect objects on or under the surface of the water, such as other vessels. "Sonar" can refer to one of two types of technology: ''passive'' sonar means listening for the sound made by vessels; ''active'' sonar means emitting pulses of sounds and listening for echoes. Sonar may be used as a means of acoustic location and of measurement of the echo characteristics of "targets" in the water. Acoustic location in air was used before the introduction of radar. Sonar may also be used for robot navigation, and SODAR (an upward-looking in-air sonar) is used for atmospheric investigations. The term ''sonar'' is also used for the equipment used to generate and receive the sound. The acoustic frequencies used in sonar systems vary from very low (infrasonic ...

Britannia Royal Naval College
Britannia Royal Naval College (BRNC), commonly known as Dartmouth, is the naval academy of the United Kingdom and the initial officer training establishment of the Royal Navy. It is located on a hill overlooking the port of Dartmouth, Devon, England. Royal Naval officer training has taken place in Dartmouth since 1863. The buildings of the current campus were completed in 1905. Earlier students lived in two wooden hulks moored in the River Dart. Since 1998, BRNC has been the sole centre for Royal Naval officer training. History The training of naval officers at Dartmouth dates from 1863, when the wooden hulk was moved from Portland and moored in the River Dart to serve as a base. In 1864, after an influx of new recruits, ''Britannia'' was supplemented by . Prior to this, a Royal Naval Academy (later Royal Naval College) had operated for more than a century from 1733 to 1837 at Portsmouth, a major naval installation. The original ''Britannia'' was replaced by the in 1869, whi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
