Ghadir (submarine)
Ghadir (, ; named after the Event of Ghadir Khumm, Ghadir Khumm) is a Ship class, class of midget submarines built by Iran specifically for cruising within the shallow waters of the Persian Gulf. The Islamic Republic of Iran Navy is the sole operator of this class, whose all submarines serve in the Southern Fleet (Iran), Southern Fleet. No submarine of this class is active at the 4th Naval Region (Islamic Republic of Iran Navy), Northern Fleet, i.e. the Caspian Sea. 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.

Hoot (torpedo)
The Hoot (; ''Whale'') is an Iranian supercavitation torpedo claimed to travel at approximately , several times faster than a conventional torpedo. It was claimed to have been successfully test-fired from a surface ship against a dummy submarine during the Iranian military exercise "Great Prophet" () on 2 April 2006 and 3 April 2006. Iran test-fired the torpedo within its territorial waters in the Strait of Hormuz in May 2017. The official Iranian news agency IRNA claims the torpedo was produced and developed by the Islamic Revolutionary Guard Corps (). Most military and industry analysts have concluded that the Hoot is reverse engineered from the Russian VA-111 Shkval supercavitation torpedo which travels at the same speed.

Valfajr (torpedo)
Valfajr is a modern homing torpedo A modern torpedo is an underwater ranged weapon launched above or below the water surface, self-propelled towards a target, with an explosive warhead designed to detonate either on contact with or in proximity to the target. Historically, such ... system designed, developed, and tested by Iran's Ministry of Defence. History In 2011, it was presented by the Iranian Ministry of Defence and Armed Forces Logistics (Iran), Ministry of Defence. Brigadier General Hossein Dehghan (Iran's defence minister) and Flotilla Admiral Habibollah Sayyari (the Commander of the Islamic Republic of Iran Navy, Iranian regular Navy) opened the production line on 13 October 2015. In the opening ceremony, Dehghan stated that "the torpedo is capable of destroying various marine targets, including large vessels, in a few seconds." In October 2015, Iran started mass-production of the Valfajr and has claimed that the weapon has now been upgraded with an anti-jammi ...

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 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) to e ...

Propeller
A propeller (often called a screw if on a ship or an airscrew if on an aircraft) is a device with a rotating hub and radiating blades that are set at a pitch to form a helical spiral which, when rotated, exerts linear thrust upon a working fluid such as water or air. Propellers are used to pump fluid through a pipe or duct, or to create thrust to propel a boat through water or an aircraft through air. The blades are shaped so that their rotational motion through the fluid causes a pressure difference between the two surfaces of the blade by Bernoulli's principle which exerts force on the fluid. Most marine propellers are screw propellers with helical blades rotating on a propeller shaft (ship), propeller shaft with an approximately horizontal axis. History Early developments The principle employed in using a screw propeller is derived from stern sculling. In sculling, a single blade is moved through an arc, from side to side taking care to keep presenting the blade to the wat ...

Draft (hull)
The draft or draught of a ship is a determined depth of the vessel below the waterline, measured vertically to its hull's lowest—its propellers, or keel, or other reference point. Draft varies according to the loaded condition of the ship. A deeper draft means the ship will have greater vertical depth below the waterline. Draft is used in under keel clearance calculations, where the draft is calculated with the available depth of water (from Electronic navigational charts) to ensure the ship can navigate safely, without grounding. Navigators can determine their draught by calculation or by visual observation (of the ship's painted load lines). Related terminology A ship's draft/draught is the "depth of the vessel below the waterline measured vertically to the lowest part of the hull, propellers, or other reference point". That is, the draft or draught is the maximum depth of any part of the vessel, including appendages such as rudders, propellers and drop keels if de ...

Beam (nautical)
The beam of a ship is its width at its widest point. The maximum beam (BMAX) is the distance between planes passing through the outer sides of the ship, beam of the hull (BH) only includes permanently fixed parts of the hull, and beam at waterline (BWL) is the maximum width where the hull intersects the surface of the water. Generally speaking, the wider the beam of a ship (or boat), the more initial stability it has, at the expense of secondary stability in the event of a capsize, where more energy is required to right the vessel from its inverted position. A ship that heels on her ''beam ends'' has her deck beams nearly vertical. Typical values Typical length-to-beam ratios ( aspect ratios) for small sailboats are from 2:1 (dinghies to trailerable sailboats around ) to 5:1 (racing sailboats over ). Large ships have widely varying beam ratios, some as large as 20:1. Rowing shells designed for flatwater racing may have length to beam ratios as high as 30:1, while a cora ...

The Pakistan Navy (PN) (; ''romanized'': Pākistān Bahrí'a; ) is the naval warfare branch of the Pakistan Armed Forces. The Chief of the Naval Staff, a four-star admiral, commands the navy and is a member of the Joint Chiefs of Staff Committee. The Pakistan Navy operates on the coastline of Pakistan in the Arabian Sea and Gulf of Oman. It was established in August 1947, following the creation of Pakistan. The primary role of the Pakistan Navy is to defend Pakistan's sea frontiers from any external enemy attack. In addition to its war services, the Navy has mobilized its war assets to conduct humanitarian rescue operations at home as well as participating in multinational task forces mandated by the United Nations to prevent seaborne terrorism and piracy off the coasts. The Pakistan Navy is a volunteer force which has been in conflict with neighbouring India twice on its sea borders. It has been repeatedly deployed in the Indian Ocean to act as a military advisor ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
