SEAL Delivery Vehicle
The SEAL Delivery Vehicle (SDV) is a crewed submersible and a type of swimmer delivery vehicle used to deliver United States Navy SEALs and their equipment for special operations missions. It is also operated by the Royal Navy's Special Boat Service, which operates three SDVs. The SDV, which has been in continuous service since 1983, is used primarily for covert or clandestine missions to denied access areas (either held by hostile forces or where military activity would draw notice and objection). It is generally deployed from the Dry Deck Shelter on a specially-modified attack or ballistic missile submarines, although it can also be launched from surface ships or land. It has seen combat in the Gulf War, Iraq War, and the US intervention in Somalia. The SDV was intended to be replaced with the Advanced SEAL Delivery System (ASDS), a larger, dry submersible that is often confused with the SDV. The SDV is flooded, and the swimmers ride exposed to the water, breathing from ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Special Boat Service
The Special Boat Service (SBS) is the special forces unit of the United Kingdom's Royal Navy. The SBS can trace its origins back to the Second World War when the Army Special Boat Section was formed in 1940. After the Second World War, the Royal Navy formed special forces with several name changes—Special Boat Company was adopted in 1951 and re-designated as the Special Boat Squadron in 1974—until on 28 July 1987 when the unit was renamed as the Special Boat Service after assuming responsibility for maritime counter-terrorism. Most of the operations conducted by the SBS are highly classified, and are rarely commented on by the British government or the Ministry of Defence, owing to their sensitive nature. The Special Boat Service is the maritime special forces unit of the United Kingdom Special Forces and is described as the sister unit of the British Army 22nd Special Air Service Regiment (22nd SAS), with both under the operational control of the Director Special Forces. ...

Los Angeles-class Submarine
The ''Los Angeles'' class of submarines are Nuclear marine propulsion, nuclear-powered fast attack submarines (hull classification symbol, SSN) in service with the United States Navy. Also known as the 688 class (pronounced "six-eighty-eight") after the hull number of lead vessel , 62 were built from 1972 to 1996, the latter 23 to an improved 688i standard. As of 2022, 26 of the ''Los Angeles'' class remain Ship commissioning, in commission — more than any other class in the world — and they account for more than half of the U.S. Navy's 50 fast attack submarines. Of the 34 retired boats, a few were in commission for nearly 40 years, including , and . With a wide variance in longevity, 12 of the 688s were laid up halfway through their projected lifespans, being the youngest-retired at 15 years, 11 months. Another five also laid up early (20–25 years), due to their Refueling and overhaul, midlife reactor refueling being cancelled, and USS Miami (SSN-755)#2012 fire, one was l ...

Attack Submarine
An attack submarine or hunter-killer submarine is a submarine specifically designed for the purpose of attacking and sinking other submarines, surface combatants and merchant vessels. In the Soviet and Russian navies they were and are called "multi-purpose submarines". They are also used to protect friendly surface combatants and missile submarines. Some attack subs are also armed with cruise missiles, increasing the scope of their potential missions to include land targets. Attack submarines may be either nuclear-powered or diesel-electric ("conventionally") powered. In the United States Navy naming system, and in the equivalent NATO system (STANAG 1166), nuclear-powered attack submarines are known as SSNs and their anti-submarine (ASW) diesel-electric predecessors are SSKs. In the US Navy, SSNs are unofficially called "fast attacks". History Origins During World War II, submarines that fulfilled the offensive surface attack role were termed fleet submarines in the U.S. Nav ...

Sleeping Beauty (canoe)
The Motorised Submersible Canoe (MSC), nicknamed Sleeping Beauty, was built by the British Special Operations Executive (SOE) during World War II as an underwater vehicle for a single frogman to perform clandestine reconnaissance or attacks against enemy vessels. Design The MSC was designed by Major Hugh Reeves, R.E., who was also given the task of designing an 'unspecified device' for an underwater approach.Rees, 2008 based on an idea from Lt Col "Blondie" Hasler which he called the 'underwater glider' and developed at Aston House to Hasler's specifications. The craft got its nickname "Sleeping Beauty" when Reeves was found sleeping in it by a passing officer. Constructed of mild steel, the canoe is long with a beam of , used a 5 hp electric motor powered by four 6-volt batteries, had a top speed of , and could travel at a cruising speed of . Its maximum operating depth was . The Sleeping Beauty was designed to carry up to of explosives as well as being able to be d ...

Human Torpedo
Human torpedoes or manned torpedoes are a type of diver propulsion vehicle on which the diver rides, generally in a seated position behind a fairing. They were used as secret naval weapons in World War II. The basic concept is still in use. The name was commonly used to refer to the weapons that Italy, and later (with a larger version) Britain, deployed in the Mediterranean and used to attack ships in enemy harbors. The human torpedo concept has occasionally been used by recreational divers, although this use is closer to midget submarines. History of common wartime models The concept of a small, manned submarine carrying a bomb was developed and patented by a British naval officer in 1909, but was never used during the First World War. The Italian Navy experimented with a primitive tiny sub (Mignatta) carrying two men and a limpet mine: this craft successfully sank Austro-Hungarian battleship SMS ''Viribus Unitis'' on 1 November 1918. The first truly practical human to ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Regia Marina
The ''Regia Marina'' (; ) was the navy of the Kingdom of Italy (''Regno d'Italia'') from 1861 to 1946. In 1946, with the Italian constitutional referendum, 1946, birth of the Italian Republic (''Repubblica Italiana''), the ''Regia Marina'' changed its name to ''Marina Militare'' ("Military Navy"). Origins The ''Regia Marina'' was established on 17 March 1861 following the proclamation of the formation of the Kingdom of Italy (1861–1946), Kingdom of Italy. Just as the Kingdom was a unification of various states in the Italian Peninsula, Italian peninsula, so the ''Regia Marina'' was formed from the navies of those states, though the main constituents were the Real Marina (Kingdom of the Two Sicilies), navies of the former kingdoms of Kingdom of Sardinia, Sardinia and Kingdom of Naples, Naples. The new Navy inherited a substantial number of ships, both sail- and steam-powered, and the long naval traditions of its constituents, especially those of Sardinia and Naples, but also ...

Office Of Strategic Services
The Office of Strategic Services (OSS) was the intelligence agency of the United States during World War II. The OSS was formed as an agency of the Joint Chiefs of Staff (JCS) to coordinate espionage activities behind enemy lines for all branches of the United States Armed Forces. Other OSS functions included the use of propaganda, subversion, and post-war planning. The OSS was dissolved a month after the end of the war. Intelligence tasks were shortly later resumed and carried over by its successors the Department of State's Bureau of Intelligence and Research (INR), and the independent Central Intelligence Agency (CIA). On December 14, 2016, the organization was collectively honored with a Congressional Gold Medal. Origin Prior to the formation of the OSS, the various departments of the executive branch, including the State, Treasury, Navy, and War Departments conducted American intelligence activities on an ''ad hoc'' basis, with no overall direction, coordination, or ...

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] |
Honolulu Star Advertiser
The ''Honolulu Star-Advertiser'' is the largest daily newspaper in Hawaii, formed in 2010 with the merger of ''The Honolulu Advertiser'' and the ''Honolulu Star-Bulletin'' after the acquisition of the former by Black Press, which already owned the latter. History On February 25, 2010, Canadian publisher Black Press Ltd., which owned the ''Honolulu Star-Bulletin'', purchased ''The Honolulu Advertiser'', then owned by Gannett Corporation for $125 million. As part of the deal to acquire the ''Advertiser'', Black Press agreed to place the ''Star-Bulletin'' on the selling block. If no buyer came forward by March 29, 2010, Black Press would start making preparations to operate both papers through a transitional management team and then combine the two dailies into one. On March 30, 2010, three parties came forward with offers to buy the ''Star-Bulletin'', but a month later on April 27, 2010, the bids were rejected because their bids for the ''Star-Bulletin'' was below the minimum liq ...

Wet Sub
A wet sub is a type of underwater vehicle, either a submarine or a submersible, that does not provide a dry environment for its occupants. It is also described as an underwater vehicle where occupants are exposed to ambient environment during operations. The watercraft is classified as medium-sized or small vessel. This type of submarine differs from other underwater personal transport devices by the fact that it has a hull around it and it is not a "bare bones" design. Usually, scuba divers ride outside the device as one would ride a motorcycle or in a semi-enclosed opening like a kayak or bobsled, although it can be designed to fully enclose its occupant(s) to reduce drag. An enclosed vehicle may also provide a dry viewing chamber for the occupant(s). The sub is generally propelled by an electric motor and is battery powered. The depth and endurance is typically limited by the requirements of the divers, particularly water temperature and breathable air. Military use Wet subs h ...

Advanced SEAL Delivery System
The Advanced SEAL Delivery System (ASDS) was a midget submarine operated by the United States Navy and United States Special Operations Command. It provided stealthy submerged transportation for United States Navy SEALs from the decks of nuclear submarines for use as an insertion platform for covert and clandestine special operations missions. The ASDS was canceled in 2009 due to cost overruns and reliability issues, after the prototype was destroyed in a fire in 2008. , the Navy plans to replace the ASDS with the Dry Combat Submersible, a similar midget submarine being developed by Lockheed Martin. Mission ASDS was conceived to address the need for stealthy long-range insertion of special operations forces on covert or clandestine missions. It was designed to replace the wet SEAL Delivery Vehicle (SDV), which exposed combat swimmers to long, cold waits during transit that impeded combat readiness on arrival, limited operational range, and hindered underwater navigational capabil ...
