Mk 48 Torpedo
The Mark 48 and its improved Advanced Capability (ADCAP) variant are American heavyweight submarine-launched torpedoes. They were designed to sink deep-diving nuclear-powered submarines and high-performance surface ships. History The Mark 48 was initially developed as REsearch TORpedo Concept II (RETORC II), one of several weapons recommended for implementation by Project Nobska, a 1956 summer study on submarine warfare. The Mk-48 torpedo was designed at the end of the 1960s to keep up with the advances in Soviet submarine technology. Operational since 1972, it replaced the Mk-37, Mk-14 and Mk-16 torpedoes as the principal weapon of U.S. Navy submarines. With the entry into service of the new Soviet in 1977, the decision was made to accelerate the ADCAP program, which would bring significant modifications to the torpedo. Tests were run to ensure that the weapon could keep up with the developments and the weapon was modified with improved acoustics and electronics. The new ve ...

Otto Fuel II
Otto fuel II is a monopropellant mixture of chiefly propylene glycol dinitrate (an ester of nitric acid and propylene glycol, and structurally similar to nitroglycerin) that is used to drive torpedoes and other weapon systems. It was invented by Otto Reitlinger in 1963 (although tests with the substance had taken place before, for example in 1960). Otto fuel II, sometimes known simply as Otto fuel, is not related to the Otto cycle; it is named after Reitlinger and for being the second iteration of the fuel. It was developed by the US Navy and the first torpedo to use it was the Mark 48 torpedo in the 1960s. Properties Otto fuel II is a distinct-smelling (described by submariners as being similar in smell to methyl salicylate, wintergreen oil; i.e. sweet, fruity and minty), reddish-orange, oily liquid that is a mixture of three synthetic substances: propylene glycol dinitrate (the major component), 2-Nitrodiphenylamine, 2-nitrodiphenylamine, and dibutyl sebacate.

Ballistic Missile Submarines
A ballistic missile submarine is a submarine capable of deploying submarine-launched ballistic missiles (SLBMs) with nuclear warheads. These submarines became a major weapon system in the Cold War because of their deterrence theory, nuclear deterrence capability. They can fire missiles thousands of kilometers from their targets, and acoustic quieting makes them difficult to detect (see acoustic signature), thus making them a survivable deterrent in the event of a Pre-emptive nuclear strike, first strike and a key element of the mutual assured destruction policy of nuclear deterrence. The deployment of ballistic missile submarines is dominated by the United States, Russia (following the collapse of the Soviet Union) and China. In fact, 70% of nuclear warheads in the USA are carried by ballistic missile submarines.Rafal, A. S. (2021).

Exercise RIMPAC
The Rim of the Pacific Exercise (RIMPAC) is the world's largest international maritime warfare exercise. RIMPAC is held biennially during June and July of even-numbered years from Honolulu, Hawaii, with the exception of 2020 where it was held in August. It is hosted and administered by the Indo-Pacific Command, headquartered at Pearl Harbor, in conjunction with the Marine Corps, the Coast Guard, and Hawaii National Guard forces under the control of the Governor of Hawaii. Participants The first RIMPAC, held in 1971, involved forces from Australia, Canada, New Zealand, the United Kingdom (UK), and the United States (US). Australia, Canada, and the US have participated in every RIMPAC since then. Other regular participants are Chile, Colombia, France, India, Indonesia, Japan, Malaysia, the Netherlands, Peru, Singapore, South Korea, and Thailand. The Royal New Zealand Navy was frequently involved until the 1985 ANZUS nuclear ships dispute and was subsequently absent, until r ...

Mark 16 Torpedo
The Mark 16 torpedo was a redesign of the United States Navy's standard Mark 14 torpedo in use during World War II. It incorporated war-tested improvements into a weapon designed to be used in unmodified United States fleet submarines. Due to high unit cost and the Mark 14's unreliability issues being solved by mid-1943, they were never put into mass production. Following WWII, limited numbers of the weapon were produced. The weapon was considered the United States' standard anti-shipping torpedo for twenty years;Kurak, September 1966, p.144 despite significant numbers of Mark 14 torpedoes left over from wartime production. This hydrogen peroxide propelled, torpedo was long and weighed . The Mod 0 warhead contained of Torpex Torpex ("Torpedo explosive") is a secondary explosive, 50% more powerful than TNT by mass. Torpex comprises 42% RDX, 40% TNT and 18% powdered aluminium. It was used in the Second World War from late 1942, at which time some used the names Torp ... ( ...

Mark 14 Torpedo
The Mark 14 torpedo was the United States Navy's standard submarine-launched anti-ship torpedo of World War II. This weapon was plagued with many problems which crippled its performance early in the war. It was supplemented by the Mark 18 electric torpedo in the last two years of the war. From December 1941 to November 1943 the Mark 14 and the destroyer-launched Mark 15 torpedo had numerous technical problems that took almost two years to fix. After the fixes, the Mark 14 played a major role in the devastating blow U.S. Navy submarines dealt to the Japanese naval and merchant marine forces during the Pacific War. By the end of World War II, the Mark 14 torpedo was a reliable weapon ultimately remaining in service for almost 40 years in the U.S. Navy, and even longer with other navies. Development The design of the Mark 14 started in January 1931; the Navy allocated $143,000 for its development. The Mark 14 was to serve in the new "fleet" submari ...

Mark 37 Torpedo
The Mark 37 torpedo is a torpedo with electrical propulsion, developed for the US Navy after World War II. It entered service with the US Navy in the early 1950s, with over 3,300 produced. It was phased out of service with the US Navy during the 1970s, and the stockpiles were sold to foreign navies. Development Its engineering development began in 1946 by Westinghouse. It was largely based on the concept of the passive homing Mark 27, with added active homing system tested on modified Mark 18s, and a new torpedo body. Between 1955 and 1956, thirty torpedoes were produced for development testing, with large-scale production commenced shortly afterwards. Due to its electric propulsion, the torpedo swam smoothly out of the launch tube, instead of having to be ejected by pressurized air, therefore significantly reducing its acoustic launch signature. To allow for water flow around the torpedo while swimming out, several 1" thick guide studs were attached to the torpedo, which al ...

Soviet Navy
The Soviet Navy was the naval warfare Military, uniform service branch of the Soviet Armed Forces. Often referred to as the Red Fleet, the Soviet Navy made up a large part of the Soviet Union's strategic planning in the event of a conflict with the opposing superpower, the United States, during the Cold War (1945–1991). The Soviet Navy played a large role during the Cold War, either confronting the North Atlantic Treaty Organization in western Europe or power projection to maintain its Warsaw Pact, sphere of influence in eastern Europe. The Soviet Navy was divided into four major fleets: the Soviet Northern Fleet, Northern, Pacific Fleet (Russia), Pacific, Black Sea Fleet, Black Sea, and Baltic Fleet, Baltic Fleets, in addition to the Leningrad Naval Base, which was commanded separately. It also had a smaller force, the Caspian Flotilla, which operated in the Caspian Sea and was followed by a larger fleet, the 5th Operational Squadron, 5th Squadron, in the Mediterranean Sea. The ...

Annapolis, Maryland
Annapolis ( ) is the capital of the U.S. state of Maryland. It is the county seat of Anne Arundel County and its only incorporated city. Situated on the Chesapeake Bay at the mouth of the Severn River, south of Baltimore and about east of Washington, D.C., Annapolis forms part of the Baltimore–Washington metropolitan area. The 2020 census recorded its population as 40,812, an increase of 6.3% since 2010. This city served as the seat of the Confederation Congress, formerly the Second Continental Congress, and temporary national capital of the United States in 1783–1784. At that time, General George Washington came before the body convened in the new Maryland State House and resigned his commission as commander of the Continental Army. A month later, the Congress ratified the Treaty of Paris of 1783, ending the American Revolutionary War, with Great Britain recognizing the independence of the United States. The city and state capitol was also the site of the 1 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Submarine Warfare
Submarine warfare is one of the four divisions of underwater warfare, the others being anti-submarine warfare, Naval mine, mine warfare and Naval mine, mine countermeasures. Submarine warfare consists primarily of Diesel engine, diesel and nuclear submarines using torpedoes, missiles or nuclear weapons, as well as advanced sensing equipment, to attack other submarines, ships, or land targets. Submarines may also be used for reconnaissance and landing of special forces as well as deterrence. In some navies they may be used for task force screening. The effectiveness of submarine warfare partly depends on the anti-submarine warfare carried out in response. American Revolution The first attack by a submarine occurred on September 8, 1776, by the American submarine ''Turtle (submersible), Turtle'' in an unsuccessful attack on the British warship ''Eagle.'' American Civil War The age of submarine warfare began during the American Civil War. The 1860s was a time of many turning ...

Project Nobska
Project Nobska was a 1956 summer study on anti-submarine warfare (ASW) for the United States Navy ordered by Chief of Naval Operations Admiral Arleigh Burke. It is also referred to as the Nobska Study, named for its location on Nobska Point near the Woods Hole Oceanographic Institution (WHOI) on Cape Cod, Massachusetts. The focus was on the ASW implications of nuclear submarines, particularly on new technologies to defend against them. The study was coordinated by the Committee on Undersea Warfare (CUW) of the National Academy of Sciences (NAS). It was notable for including 73 representatives from numerous organizations involved in submarine design, submarine-related fields, and weapons design, including senior scientists from the Atomic Energy Commission's nuclear weapons laboratories. Among the participants were Nobel laureate Isidor Rabi, Paul Nitze, and Edward Teller. The study's recommendations influenced all subsequent US Navy submarine designs, as well as submarine-laun ...
