USS Caiman
USS ''Caiman'' (SS-323), a ''Balao''-class submarine, was a ship of the United States Navy that was later transferred to the Turkish Naval Forces in 1972 under the Security Assistance Program, where she was recommissioned as the third TCG ''Dumlupınar''. She was retired in 1986. Career (US) Originally ''Blanquillo'', the vessel was renamed on 24 September 1942 after the caiman, a fresh water alligator inhabiting the Amazon River, and launched on 30 March 1944 by Electric Boat Co., Groton, Connecticut; sponsored by Mrs. R. C. Bonjour; commissioned 17 July 1944. She reported to the Pacific Fleet. During World War II, ''Caiman'' sailed from Pearl Harbor on her first war patrol 13 November 1944. Pausing at Saipan to put ashore her severely ill commanding officer and embark his relief, the submarine pushed on to the South China Sea, where she combined offensive patrol with lifeguard duty as a part of air-sea rescue operations to save aviators downed in air strikes on enemy ...

Submarine
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 Autonomous underwater vehicle, 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 navy, navies, large and small. Military uses include attacking enemy surface ships (merchant and military) or other submarines, and for aircraft carrier protection, Blockade runner, blockade running, Ballistic missile submarine, nuclear deterrence, reconnaissance, conventio ...

World War II
World War II or the Second World War, often abbreviated as WWII or WW2, was a world war that lasted from 1939 to 1945. It involved the vast majority of the world's countries—including all of the great powers—forming two opposing military alliances: the Allies and the Axis powers. World War II was a total war that directly involved more than 100 million personnel from more than 30 countries. The major participants in the war threw their entire economic, industrial, and scientific capabilities behind the war effort, blurring the distinction between civilian and military resources. Aircraft played a major role in the conflict, enabling the strategic bombing of population centres and deploying the only two nuclear weapons ever used in war. World War II was by far the deadliest conflict in human history; it resulted in 70 to 85 million fatalities, mostly among civilians. Tens of millions died due to genocides (including the Holocaust), starvation, ma ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Electric Boat
An electric boat is a powered watercraft driven by electric motors, which are powered by either on-board battery packs, solar panels or generators. While a significant majority of water vessels are powered by diesel engines, with sail power and gasoline engines also popular, boats powered by electricity have been used for over 120 years. Electric boats were very popular from the 1880s until the 1920s, when the internal combustion engine became dominant. Since the energy crises of the 1970s, interest in this quiet and potentially renewable marine energy source has been increasing steadily, especially as more efficient solar cells have become available, for the first time making possible motorboats with a theoretically infinite cruise range like sailboats. The first practical solar boat was probably constructed in 1975 in England. The first electric sailboat to complete a round-the-world tour (including a transit of the Panama Canal) using only green technologies is EcoSail ...

Amazon River
The Amazon River (, ; es, Río Amazonas, pt, Rio Amazonas) in South America is the largest river by discharge volume of water in the world, and the disputed longest river system in the world in comparison to the Nile. The headwaters of the Apurímac River on Nevado Mismi had been considered for nearly a century as the Amazon basin's most distant source, until a 2014 study found it to be the headwaters of the Mantaro River on the Cordillera Rumi Cruz in Peru. The Mantaro and Apurímac rivers join, and with other tributaries form the Ucayali River, which in turn meets the Marañón River upstream of Iquitos, Peru, forming what countries other than Brazil consider to be the main stem of the Amazon. Brazilians call this section the Solimões River above its confluence with the Rio Negro forming what Brazilians call the Amazon at the Meeting of Waters ( pt, Encontro das Águas) at Manaus, the largest city on the river. The Amazon River has an average discharge of about – ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Alligatoridae
The family Alligatoridae of crocodylians includes alligators, caimans and their extinct relatives. Phylogeny The superfamily Alligatoroidea includes all crocodilians (fossil and extant) that are more closely related to the American alligator than to either the Nile crocodile or the gharial. This is a stem-based definition for alligators, and is more inclusive than the crown group Alligatoridae. As a crown group, Alligatoridae only includes the last common ancestor of all extant (living) alligators, caimans, and their descendants (living or extinct), whereas Alligatoroidea, as a stem-based group, also includes more basal extinct alligator ancestors that are more closely related to living alligators than to crocodiles or gavialids. When considering only living taxa (neontology), this makes Alligatoroidea and Alligatoridae redundant. The simplified cladogram below shows Alligatoridae's relationships to other extant (living) crocodilians. The below detailed cladogram show ...

Security Assistance Program
The United States Department of Defense's Foreign Military Sales (FMS) program facilitates sales of U.S. arms, defense equipment, defense services, and military training to foreign governments. The purchaser does not deal directly with the defense contractor; instead, the Defense Security Cooperation Agency (DSCA) serves as an intermediary, usually handling procurement, logistics, and delivery, often providing product support, training, and infrastructure construction (such as hangars, runways, utilities, etc.). FMS is carried out with countries that are authorized to participate and is subject to approval based on the mechanism to procure services, a deposit in a U.S. trust fund or appropriate credit, and approval to fund services. On any given day, DSCA is managing “14,000 open foreign military sales cases with 185 countries,” the DSCA director Lieutenant General Charles Hooper explained at the Brookings Institution in June 2019. Some U.S. Air Force (USAF) FMS programs are ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Turkish Navy
The Turkish Naval Forces ( tr, ), or Turkish Navy ( tr, ) is the naval warfare service branch of the Turkish Armed Forces. The modern naval traditions and customs of the Turkish Navy can be traced back to 10 July 1920, when it was established as the ''Directorate of Naval Affairs'' during the Turkish War of Independence led by Mustafa Kemal Atatürk. Since July 1949, the service has been officially known as the ''Turkish Naval Forces''. In 2008, the Turkish Navy had a reported active personnel strength of 48,600; this figure included an Amphibious Marines Brigade as well as several Special Forces and Commando detachments. As of early 2021, the navy operates a wide variety of ships and 60 maritime aircraft. History Ottoman fleet after Mudros Following the demise of the Ottoman Empire in the aftermath of World War I, on November 3, 1918, the fleet commander of the Ottoman Navy, rear admiral Arif Pasha, ordered all flags to be struck on all warships lying in the Gol ...

Balao Class Submarine
The ''Balao'' class was a successful design of United States Navy submarine used during World War II, and with 120 boats completed, the largest class of submarines in the United States Navy. An improvement on the earlier , the boats had slight internal differences. The most significant improvement was the use of thicker, higher yield strength steel in the pressure hull skins and frames, which increased their test depth to . ''Tang'' actually achieved a depth of during a test dive, and exceeded that test depth when taking on water in the forward torpedo room while evading a destroyer. Design The ''Balao''s were similar to the ''Gato''s, except they were modified to increase test depth from to . In late 1941, two of the Navy's leading submarine designers, Captain Andrew McKee and Commander Armand Morgan, met to explore increasing diving depth in a redesigned ''Gato''. A switch to a new High-Tensile Steel (HTS) alloy, combined with an increase in hull thickness from to , wo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Torpedo Tube
A torpedo tube is a cylindrical device for launching torpedoes. There are two main types of torpedo tube: underwater tubes fitted to submarines and some surface ships, and deck-mounted units (also referred to as torpedo launchers) installed aboard surface vessels. Deck-mounted torpedo launchers are usually designed for a specific type of torpedo, while submarine torpedo tubes are general-purpose launchers, and are often also capable of deploying naval mine, mines and cruise missiles. Most modern launchers are standardized on a diameter for light torpedoes (deck mounted aboard ship) or a diameter for heavy torpedoes (underwater tubes), although other sizes of torpedo tube have been used: see Torpedo#Classes and diameters, Torpedo classes and diameters. Submarine torpedo tube A submarine torpedo tube is a more complex mechanism than a torpedo tube on a surface ship, because the tube has to accomplish the function of moving the torpedo from the normal atmospheric pressure within t ...
