Makran-class Forward Base Ship
IRIS ''Makran'' () is the lead ship of ''Makran'' class of forward base ship of the Islamic Republic of Iran Navy. Ships of this class are in service with its Southern Fleet since 2021 and are named after coastal region in southeastern Iran. ''Makran'' is a former crude oil tanker converted into a warship, she was known with the tentative title ''Khalij-e Fars'' (, a name reserved for the lead ship of Project Loghman) before her name being changed to the current. Though not officially acknowledged, TankerTrackers, a firm that tracks maritime traffic, has identified her as a Japanese-built ship completed in 2010, previously named ''Beta'' and earlier ''Al Buhaira'', and whose AIS signal was last detected in 2019 near United Arab Emirates. Its intended task/purpose is to support naval units in remote waters, especially in the North Indian Ocean, the Bab-el-Mandeb and the Red Sea. Like ''Makran'' the other two ships are also being converted from oil tanker to forward base ship. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Makran
Makran (), also mentioned in some sources as ''Mecran'' and ''Mokrān'', is the southern coastal region of Balochistan. It is a semi-desert coastal strip in the Balochistan province in Pakistan and in Iran, along the coast of the Gulf of Oman. It extends westwards, from the Sonmiani Bay to the northwest of Karachi in the east, to the fringes of the region of Bashkardia/Bāšgerd in the southern part of the Sistan and Baluchestan province of modern Iran. Makrān is thus bisected by the modern political boundary between Pakistan and Iran. In January 2025, a government spokesperson informed that Iran is investigating the possibility of moving its capital to the Makran region. Etymology The southern part of Balochistan is called ''Kech Makran'' on the Pakistani side and Makran on the Iranian side which is also the name of a former Iranian province. The location corresponds to that of the Maka satrapy in Achaemenid times. The Sumerian trading partners of Magan are identified wit ...

Aframax
An Aframax vessel is an oil tanker with a deadweight between 80,000 and 120,000 metric tonnes. The term is based on the Average Freight Rate Assessment (AFRA), a tanker rate system created in 1954 by Shell Oil to standardize shipping contract terms. Due to their favorable size, Aframax tankers can serve most ports in the world. These vessels serve regions that do not have very large ports or offshore oil terminals to accommodate Very Large Crude Carriers and Ultra-Large Crude Carriers. Aframax tankers are optimal for short- to medium-haul crude oil transportation. Aframax class tankers are largely used in the basins of the Black Sea, the North Sea, the Caribbean Sea, the South and East China Seas, and the Mediterranean The Mediterranean Sea ( ) is a sea connected to the Atlantic Ocean, surrounded by the Mediterranean basin and almost completely enclosed by land: on the east by the Levant in West Asia, on the north by Anatolia in West Asia and Southern ....

Flag Of Convenience
Flag of convenience (FOC) refers to a business practice whereby a ship's owners Ship registration, register a Merchant vessel, merchant ship in a ship register of a country other than that of the ship's owners, and the ship flies the civil ensign of that country, called the flag state.Bernaert, 2006, p. 104. The term is often used pejoratively, and although common, the practice is sometimes regarded as contentious. Each merchant ship is required by international law to be registered in a registry created by a country,ICFTU et al., 2002, p. 7. and a ship is subject to the laws of that country, which are used also if the ship is involved in a case under admiralty law. A ship's owners may elect to register a ship in a foreign country so as to avoid the regulations of the owners' country, which may, for example, have stricter safety standards. They may also select a jurisdiction to reduce operating costs, avoiding higher taxes in the owners' country and bypassing laws that protect ...

Unmanned Aerial Vehicle
An unmanned aerial vehicle (UAV) or unmanned aircraft system (UAS), commonly known as a drone, is an aircraft with no human pilot, crew, or passengers onboard, but rather is controlled remotely or is autonomous.De Gruyter Handbook of Drone Warfare; 2024. e-ISBN (PDF) 978-3-11-074203-9.H. Pan; M. Zahmatkesh; F. Rekabi-Bana; F. Arvin; J. HuT-STAR: Time-Optimal Swarm Trajectory Planning for Quadrotor Unmanned Aerial Vehicles IEEE Transactions on Intelligent Transportation Systems, 2025. UAVs were originally developed through the twentieth century for military missions too "dull, dirty or dangerous" for humans, and by the twenty-first, they had become essential assets to most militaries. As control technologies improved and costs fell, their use expanded to many non-military applications. These include aerial photography, area coverage,F. Rekabi-Bana; Hu, J.; T.

VTOL
A vertical take-off and landing (VTOL) aircraft is one that can takeoff and landing, take off and land vertically without relying on a runway. This classification can include a variety of types of aircraft including helicopters as well as thrust-vectoring fixed-wing aircraft and other hybrid aircraft with powered helicopter rotor, rotors such as cyclogyro, cyclogyros/cyclocopters and gyrodynes. Some VTOL aircraft can operate in other modes as well, such as CTOL (conventional take-off & landing), STOL (short take-off & landing), or STOVL (short take-off & vertical landing). Others, such as some helicopters, can only operate as VTOL, due to the aircraft lacking landing gear that can handle taxiing. VTOL is a subset of V/STOL (vertical or short take-off & landing). Some aerostat, lighter-than-air aircraft also qualify as VTOL aircraft, as they can hover, takeoff and land with vertical approach/departure profiles. Electric vertical takeoff and landing aircraft, or eVTOLs, are being ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Helicopter Deck
A helicopter deck (or helo deck) is a helicopter pad on the deck of a ship, usually located on the stern and always clear of obstacles that would prove hazardous to a helicopter landing. In the United States Navy, it is commonly and properly referred to as the flight deck. In the UK's Fleet Air Arm, ''landing on'' is usually achieved by first lining up on the port quarter parallel to the ship's heading, then once the deck motion is deemed to be acceptable the pilot sidesteps the aircraft laterally using a white painted line (the bum line) as a reference. Shipboard landing for some helicopters is assisted though use of a haul-down device that involves attachment of a cable to a probe on the bottom of the aircraft prior to landing. Tension is maintained on the cable as the helicopter descends, assisting the pilot with accurate positioning of the aircraft on the deck; once on deck locking beams close on the probe, locking the aircraft to the flight deck. This device was pioneered b ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mother Ship
A mother ship, mothership or mother-ship is a large vehicle that leads, serves, or carries other smaller vehicles. A mother ship may be a maritime ship, aircraft, or spacecraft. Examples include bomber aircraft, bombers converted to carry experimental aircraft to altitudes where they can conduct their research (such as the B-52 carrying the X-15), or ships that carry small submarines to an area of ocean to be explored (such as the R/V Atlantis (AGOR-25), Atlantis II carrying the DSV Alvin, ''Alvin''). A mother ship may also be used to recover smaller craft, or go its own way after releasing them. A smaller vessel serving or caring for ''larger'' craft is usually called a tender ship, tender. Maritime craft During World War II, the German Type XIV submarine or ''Milchkuh'' (Milk cow) was a type of large submarine used to resupply the U-boats. Mother ships can carry small submersibles and submarines to an area of ocean to be explored (such as the R/V Atlantis (AGOR-25), Atla ...

Sea Trial
A sea trial or trial trip is the testing phase of a watercraft (including boats, ships, and submarines). It is also referred to as a "shakedown cruise" by many naval personnel. It is usually the last phase of construction and takes place on open water, and it can last from a few hours to many days. Sea trials are conducted to measure a vessel's performance and general seaworthiness. Testing of a vessel's speed, maneuverability, equipment and safety features are usually conducted. Usually in attendance are technical representatives from the builder (and from builders of major systems), governing and certification officials, and representatives of the owners. Successful sea trials subsequently lead to a vessel's certification for commissioning and acceptance by its owner. Although sea trials are commonly thought to be conducted only on new-built vessels (referred by shipbuilders as 'builders trials'), they are regularly conducted on commissioned vessels as well. In new vessels, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bandar Abbas
Bandar Abbas (, ) is a city in the Central District of Bandar Abbas County, Hormozgan province, Iran, serving as capital of the province, the county, and the district. Bandar Abbas is a port on the southern coast of the country, on the Persian Gulf. The city occupies a strategic position on the narrow Strait of Hormuz (just across from Musandam Governorate, Oman). It is the location of the main base and headquarters of the Iranian Navy. Etymology Bandar Abbas has always been a port, and as such its various names have all reflected this function. The most common name over time was Gameroon, with various spellings. In Henry Yule's dictionary of Anglo-Indian jargon two etymologies are given; the first derived from ''gümrük'', "customhouse" (from Late Greek ''kommerkion'', from Latin ''commercium'', "commerce"). The second, which Yule found much more convincing, comes from Persian ''kamrūn'', "shrimp" (in Portuguese: ''camarão'', similar to the former Portuguese name). Its ...

Gross Tonnage
Gross tonnage (GT, G.T. or gt) is a nonlinear measure of a ship's overall internal volume. Gross tonnage is different from gross register tonnage. Neither gross tonnage nor gross register tonnage should be confused with measures of mass or weight such as deadweight tonnage or displacement. Gross tonnage, along with net tonnage, was defined by the ''International Convention on Tonnage Measurement of Ships, 1969'', adopted by the International Maritime Organization (IMO) in 1969, and came into force on 18 July 1982. These two measurements replaced gross register tonnage (GRT) and net register tonnage (NRT). Gross tonnage is calculated based on "the moulded volume of all enclosed spaces of the ship" and is used to determine things such as a ship's manning regulations, safety rules, registration fees, and port dues, whereas the older gross register tonnage is a measure of the volume of only certain enclosed spaces.
