Photonics Mast
A photonics mast (or '' optronics mast''BBC News Scotland, A vision of evolving technologies' 30 August 2007, 13:06 GMT) is a sensor on a submarine which functions similarly to a periscope without requiring a periscope tube, thus freeing design space during construction and limiting risks of water leakage in the event of damage. A photonics mast replaces the mechanical, line-of-sight viewing system with digital equipment, similar to a digital camera array, and it has fewer locational and dimensional constraints than a traditional periscope. Unlike a periscope, it need not be located directly above its user, and it requires only a small pressure hull penetration for cabling. This allows the photonics mast to fit entirely within the sail of the submarine and means the control room need not be placed directly below the sail. A photonics mast operates by rising above the water in a manner similar to a telescoping antenna and provides information through an array of sensors, such ...

Photonics Mast Array 01
Photonics is a branch of optics that involves the application of generation, detection, and manipulation of light in form of photons through emission, transmission, modulation, signal processing, switching, amplification, and sensing. Though covering all light's technical applications over the whole spectrum, most photonic applications are in the range of visible and near-infrared light. The term photonics developed as an outgrowth of the first practical semiconductor light emitters invented in the early 1960s and optical fibers developed in the 1970s. History The word 'Photonics' is derived from the Greek word "phos" meaning light (which has genitive case "photos" and in compound words the root "photo-" is used); it appeared in the late 1960s to describe a research field whose goal was to use light to perform functions that traditionally fell within the typical domain of electronics, such as telecommunications, information processing, etc. Photonics as a field began with t ...

Borei-class Submarine
The Borei class, alternate transliteration Borey, Russian designation Project 955 ''Borei'' and Project 955A ''Borei-A'' (russian: Борей, , Boreas, NATO reporting name Dolgorukiy), are a series of nuclear-powered ballistic missile submarines being constructed by Sevmash for the Russian Navy. The class is projected to replace the Soviet-era Delta III, Delta IV and classes in Russian Navy service. Despite being a replacement for many types of SSBNs, Borei-class submarines are much smaller than those of the Typhoon class in both volume and crew (24,000 tons opposed to 48,000 tons and 107 personnel as opposed to 160 for the Typhoons). In terms of ''class'', they are more accurately a follow-on for the Delta IV-class SSBNs. History The first design work on the project started in the mid-1980s and the construction of the first vessel started in 1996. Previously, a short-lived, smaller parallel design appeared in 1980s with designation Project 935 Borei II. A new submarine ...

Yasen-class Submarine
The Yasen class, Russian designations Project 885 Yasen and Project 885M Yasen-M (russian: Ясень, , ash tree, NATO reporting name: Severodvinsk), also referred to as the ''Graney'' class, are a series of nuclear-powered cruise missile submarines designed by the Malakhit Marine Engineering Bureau and built by Sevmash for the Russian Navy. Design work commenced in earnest in the 1980s with the first submarine built in the 1990s–early 2010s with commissioning in 2013. Two additional boats to a modified (and slightly shorter overall) ''Yasen-M'' design were commissioned in 2021 and six more are under construction. Based on the and designs, the ''Yasen'' class is projected to replace the Russian Navy's current Soviet-era nuclear attack submarines. The Akula class is optimised for a hunter-killer role, whereas the Yasen class concept uses the platform as a nuclear guided missile submarine (SSGN). History The ''Yasen''-class submarines were designed by Malakhit, which was for ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Thales Group
Thales Group () is a French multinational company that designs, develops and manufactures electrical systems as well as devices and equipment for the aerospace, defence, transportation and security sectors. The company is headquartered in Paris' business district, La Défense, and its stock is listed on the Euronext Paris.

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] |
Sōryū-class Submarine
The ''Sōryū''-class submarines (''16SS'') are diesel-electric attack submarines. The first boat in the class entered service with the Japan Maritime Self-Defense Force in 2009. The design is an evolution of the , from which it can most easily be distinguished by its X-shaped stern combination diving planes and rudders. The ''Sōryūs'' have the largest displacement of any submarine used by post-war Japan. It is Japan's first air-independent propulsion submarine. From ''Sōryū'' to ''Shōryū'' are fitted with Kockums Naval Solutions Stirling engines license-built by Kawasaki Heavy Industries, allowing them to stay submerged for longer periods of time. Furthermore, ''Ōryū'' is the world's first lithium-ion battery submarine. The cost of the sixth submarine (''Kokuryū'') was estimated at 540 million USD. In 2019, the replacement to the ''Sōryū''s, the Taigei-class submarine, entered the planning phase. Naming convention Japanese submarines since World War II were named af ...

Laser Rangefinder
A laser rangefinder, also known as a laser telemeter, is a rangefinder that uses a laser beam to determine the distance to an object. The most common form of laser rangefinder operates on the time of flight principle by sending a laser pulse in a narrow beam towards the object and measuring the time taken by the pulse to be reflected off the target and returned to the sender. Due to the high speed of light, this technique is not appropriate for high precision sub-millimeter measurements, where triangulation and other techniques are often used. Pulse The pulse may be coded to reduce the chance that the rangefinder can be jammed. It is possible to use Doppler effect techniques to judge whether the object is moving towards or away from the rangefinder, and if so, how fast. Precision The precision of the instrument is determined by the rise or fall time of the laser pulse and the speed of the receiver. One that uses very sharp laser pulses and has a very fast detector can rang ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
