Nahang Class
The ''Nahang'' ( fa, نهنگ, lit=Whale) is an Iranian-made class of midget submarine designed for shallow water operations. Only one prototype of this class is known to be completed, although its characteristics have remained unclear. History Iran had shown interest in midget submarines in the 1980s. According to the ''Conway's All The World's Fighting Ships'', Iran assembled a midget in Bandar Abbas that was completed in 1987 in an unsuccessful attempt. Iran reportedly purchased a second midget of another design from North Korea, delivered in 1988. It is alleged that by 1993, nine midget submarines –able to displace 76 tons surfaced and 90 tons submerged, with a top speed between and – were imported from North Korea. Existence of ''Nahang'' was first known in April 2006. On 6 March 2006, Iranian state television announced that ''Nahang 1'' has been commissioned into the Southern Fleet. Later that year in late August, she participated in the third phase of Zarbat-e Zolfag ...

Swimmer Delivery Vehicle
A diver propulsion vehicle (DPV), also known as an underwater propulsion vehicle, sea scooter, underwater scooter, or swimmer delivery vehicle (SDV) by armed forces, is an item of diving equipment used by scuba divers to increase range underwater. Range is restricted by the amount of breathing gas that can be carried, the rate at which that breathing gas is consumed, and the battery power of the DPV. Time limits imposed on the diver by decompression requirements may also limit safe range in practice. DPVs have recreational, scientific and military applications. DPVs include a range of configurations from small, easily portable scooter units with a small range and low speed, to faired or enclosed units capable of carrying several divers longer distances at higher speeds. The earliest recorded DPVs were used for military purposes during World War II and were based on torpedo technology and components. Structure A DPV usually consists of a pressure-resistant watertight casing c ...

Midget Submarines
A midget submarine (also called a mini submarine) is any submarine under 150 tons, typically operated by a crew of one or two but sometimes up to six or nine, with little or no on-board living accommodation. They normally work with mother ships, from which they are launched and recovered and which provide living accommodation for the crew and support staff. Both military and civilian midget submarines have been built. Military types work with surface ships and other submarines as mother ships. Civilian and non-combatant military types are generally called submersibles and normally work with surface ships. Most early submarines would now be considered midget submarines, such as the United States Navy's and the British Royal Navy's (both named for the same designer). Military submarines Uses Midget submarines are best known for harbor penetration, although only two World War II boats, the British X-craft and the unsuccessful Welman submarine, were specifically designed with t ...

Submarines Of Iran
A submarine (or sub) is a watercraft capable of independent operation underwater. It differs from a submersible, which has more limited underwater capability. The term is also sometimes used historically or colloquially to refer to remotely operated vehicles and robots, as well as medium-sized or smaller vessels, such as the midget submarine and the wet sub. Submarines are referred to as ''boats'' rather than ''ships'' irrespective of their size. Although experimental submarines had been built earlier, submarine design took off during the 19th century, and they were adopted by several navies. They were first widely used during World War I (1914–1918), and are now used in many navies, large and small. Military uses include attacking enemy surface ships (merchant and military) or other submarines, and for aircraft carrier protection, blockade running, nuclear deterrence, reconnaissance, conventional land attack (for example, using a cruise missile), and covert insertion of spec ...

List Of Military Equipment Manufactured In Iran
In recent years, the Iranian government states that it has self-sufficiency in essential military hardware and defense systems. Tehran established an arms development program during the Iran–Iraq War to counter the weapons embargo imposed on it by the US and its Western allies. Since 1993, Iran has manufactured its own tanks, armored personnel carriers, missiles, radars, boats, submarines, unmanned aerial vehicles, and fighter planes. History From 1925 to the Iranian Revolution in 1979, Iran used to be equipped with the very latest Western hardware. Cases exist where Iran was supplied with equipment even before it was made standard in the countries that developed it (for example the US F-14 Tomcat, or the British Chieftain Tank). Primary suppliers included the United States, Britain, France, the Federal Republic of Germany (West Germany), Italy, Israel, and the Soviet Union. The Iran–Iraq War, and post revolutionary sanctions at the time had a dramatic effect on Iran's in ...

Radar Navigation
Radar navigation is the utilization of marine and aviation radar systems for vessel and aircraft navigation. When a craft is within radar range of land or special radar aids to navigation, the navigator can take distances and angular bearings to charted objects and use these to establish arcs of position and lines of position on a chart.Maloney, 2003:744. A fix consisting of only radar information is called a ''radar fix''.Bowditch, 2002:816. Some types of radar fixes include the relatively self-explanatory methods of "range and bearing to a single object,"National Imagery and Mapping Agency, 2001:163. "two or more bearings," "tangent bearings," and "two or more ranges." Parallel indexing is a technique defined by William Burger in the 1957 book ''The Radar Observer's Handbook''.National Imagery and Mapping Agency, 2001:169. This technique involves creating a line on the screen that is parallel to the ship's course, but offset to the left or right by some distance. This p ...

Surface Search Radar
A surface search radar, sometimes more accurately known as a sea-surface search radar or naval surveillance radar, is a type of military radar intended primarily to locate objects on the surface of lakes and oceans. Part of almost every modern naval ship, they are also widely used on maritime patrol aircraft and naval helicopters. When mounted on an aircraft, they are sometimes known by the British terminology, Air-to-Surface Vessel radar, or ASV for short. Similar radars are also widely used on civilian ships and even small pleasure craft, in which case they are more commonly known as marine radar. As with conventional surveillance radars, these systems detect objects by listening for the reflections of a radio signal off target objects, especially metal. The range of a surface search radar is greatly increased compared to other roles due to several aspects of the sea surfaces and the objects in it. In low sea states, water makes an excellent reflector for radio signals, which helps ...

Electronic Warfare Support Measures
In military telecommunications, electronic support (ES) or electronic support measures (ESM) gather intelligence through passive "listening" to electromagnetic radiations of military interest. They are an aspect of electronic warfare involving actions taken under direct control of an operational commander to detect, intercept, identify, locate, record, and/or analyze sources of radiated electromagnetic energy for the purposes of immediate threat recognition (such as warning that fire control RADAR has locked on a combat vehicle, ship, or aircraft) or longer-term operational planning.Polmar, Norman "The U. S. Navy Electronic Warfare (Part 1)" ''United States Naval Institute Proceedings'' October 1979 p.137 Thus, electronic support provides a source of information required for decisions involving electronic protection (EP), electronic attack (EA), avoidance, targeting, and other tactical employment of forces. Electronic support data can be used to produce signals intelligence (SIG ...

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 ...
