Ethan Allen-class Submarine
The ''Ethan Allen'' class of fleet ballistic missile submarine was an evolutionary development from the ''George Washington'' class. The ''Ethan Allen'', together with the , , , and classes comprised the "41 for Freedom" that were the Navy's main contribution to the nuclear deterrent force through the late 1980s. Design Rather than being designed as attack submarines with a missile compartment added, the ''Ethan Allen''s were the first submarines designed "from the keel up" as Fleet Ballistic Missile (FBM) submarines carrying the Polaris A-2 missile. They were functionally similar to the ''George Washington''s, but longer and more streamlined and with torpedo tubes reduced to four. In the early and mid-1970s, they were upgraded to Polaris A3s. Because their missile tubes could not be modified to carry the larger diameter Poseidon missile, they were not further upgraded. Conversions To comply with SALT II treaty limitations as the ballistic missile submarines entered ser ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
General Dynamics Electric Boat
General Dynamics Electric Boat (GDEB) is a subsidiary of General Dynamics Corporation. It has been the primary builder of submarines for the United States Navy for more than 100 years. The company's main facilities are a shipyard in Groton, Connecticut, a hull-fabrication and outfitting facility in Quonset Point, Rhode Island, and a design and engineering facility in New London, Connecticut. History The company was founded in 1899 by Isaac Rice as the Electric Boat Company to build John Philip Holland's submersible ship designs, which were developed at Lewis Nixon's Crescent Shipyard in Elizabeth, New Jersey. ''Holland VI'' was the first submarine that this shipyard built, which became when it was commissioned into the United States Navy on April 11, 1900—the first submarine to be officially commissioned. The success of ''Holland VI'' created a demand for follow-up models (A class or ) that began with the prototype submersible ''Fulton'' built at Electric Boat. Some foreig ...

UGM-27 Polaris
The UGM-27 Polaris missile was a two-stage solid-fueled nuclear-armed submarine-launched ballistic missile (SLBM). As the United States Navy's first SLBM, it served from 1961 to 1980. In the mid-1950s the Navy was involved in the Jupiter missile project with the U.S. Army, and had influenced the design by making it squat so it would fit in submarines. However, they had concerns about the use of liquid fuel rockets on board ships, and some consideration was given to a solid fuel version, Jupiter S. In 1956, during an anti-submarine study known as Project Nobska, Edward Teller suggested that very small hydrogen bomb warheads were possible. A crash program to develop a missile suitable for carrying such warheads began as Polaris, launching its first shot less than four years later, in February 1960. As the Polaris missile was fired underwater from a moving platform, it was essentially invulnerable to counterattack. This led the Navy to suggest, starting around 1959, that they be g ...

Submarine Classes
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 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 navies, large and small. Military uses include attacking enemy surface ships (merchant and military) or other submarines, and for aircraft carrier protection, blockade running, nuclear deterrence, reconnaissance, conventional land attack (for example, using a cruise missile), and covert insertion of ...

List Of Submarine Classes Of The United States Navy
Submarines of the United States Navy are built in classes, using a single design for a number of boats. Minor variations occur as improvements are incorporated into the design, so later boats of a class may be more capable than earlier. Also, boats are modified, sometimes extensively, while in service, creating departures from the class standard. However, in general, all boats of a class are noticeably similar. Experimental use: an example is , which used an unprecedented hull design. In this list such single boat "classes" are marked with "(unique)".

Fleet Ballistic Missile
A submarine-launched ballistic missile (SLBM) is a ballistic missile capable of being launched from submarines. Modern variants usually deliver multiple independently targetable reentry vehicles (MIRVs), each of which carries a nuclear warhead and allows a single launched missile to strike several targets. Submarine-launched ballistic missiles operate in a different way from submarine-launched cruise missiles. Modern submarine-launched ballistic missiles are closely related to intercontinental ballistic missiles (ICBMs), with ranges of over , and in many cases SLBMs and ICBMs may be part of the same family of weapons. History Origins The first practical design of a submarine-based launch platform was developed by the Germans near the end of World War II involving a launch tube which contained a V-2 ballistic missile variant and was towed behind a submarine, known by the code-name ''Prüfstand XII''. The war ended before it could be tested, but the engineers who had worked on i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ship-Submarine Recycling Program
The Ship-Submarine Recycling Program (SRP) is the process that the United States Navy uses to dispose of decommissioned nuclear vessels. SRP takes place only at the Puget Sound Naval Shipyard (PSNS) in Bremerton, Washington, but the preparations can begin elsewhere. Program overview Defueling and decommissioning Before SRP can begin, the vessel's nuclear fuel must be removed, and defueling usually coincides with decommissioning. Until the fuel is removed, the vessel is referred to as "USS ''Name''," but afterward, the "USS" prefix is dropped and it is referred to as "ex-''Name''." Reusable equipment is removed at the same time as the fuel. Spent fuel storage Spent nuclear fuel is shipped by rail to the Naval Reactor Facility in the Idaho National Laboratory (INL), located northwest of Idaho Falls, Idaho, where it is stored in special canisters. Hull salvage At PSNS, the SRP proper begins. The salvage workers cut the submarine into three or four pieces: the aft sect ...

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] |
Dry Deck Shelter
A dry deck shelter (DDS) is a removable module that can be attached to a submarine to allow divers easy exit and entrance while the boat is submerged. The host submarine must be specially modified to accommodate the DDS, with the appropriate mating hatch configuration, electrical connections, and piping for ventilation, divers' air, and draining water. The DDS can be used to deploy a SEAL Delivery Vehicle submersible, Navy divers, or Combat Rubber Raiding Craft (CRRC). Active and future DDS-capable submarines Royal Navy In UK service it is formally named the Special Forces Payload Bay (SFPB) and was procured under ‘Project Chalfont’ Training is conducted at the purpose-built Chalfont Shore Facility (CSF) constructed by BAE Systems at HMNB Clyde. It is used by the . United States Navy The United States Navy's DDSs are long and high and wide, add about 30 tons to its host submarine's submerged displacement, can be transported by trucks or C-5 Galaxy airplanes, and require ...

Special Operations Forces
Special forces and special operations forces (SOF) are military units trained to conduct special operations. NATO has defined special operations as "military activities conducted by specially designated, organized, selected, trained and equipped forces using unconventional techniques and modes of employment". Special forces emerged in the early 20th century, with a significant growth in the field during the Second World War, when "every major army involved in the fighting" created formations devoted to special operations behind enemy lines. Depending on the country, special forces may perform functions including Airborne forces, airborne operations, counter-insurgency, counter-terrorism, foreign internal defense, Covert operations, covert ops, Direct action (military), direct action, Hostage crises, hostage rescue, high-value targets/Manhunt (military), manhunt, intelligence, surveillance, target acquisition, and reconnaissance, intelligence operations, Mobility (military), mo ...

United States Navy SEALs
The United States Navy Sea, Air, and Land (SEAL) Teams, commonly known as Navy SEALs, are the U.S. Navy's primary special operations force and a component of the Naval Special Warfare Command. Among the SEALs' main functions are conducting small-unit special operation missions in maritime, jungle, urban, arctic, mountainous, and desert environments. SEALs are typically ordered to capture or to kill high level targets, or to gather intelligence behind enemy lines. All active SEALs are members of the U.S. Navy. The CIA's highly secretive and elite Special Operations Group (SOG) recruits operators from SEAL Teams, with joint operations going back to the MACV-SOG during the Vietnam War. This cooperation still exists today, as evidenced by military operations in Iraq and Afghanistan. History Origins Although not formally founded until 1962, the modern-day U.S. Navy SEALs trace their roots to World War II. The United States Military recognized the need for the covert reconnaiss ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Fire Control System
A fire-control system (FCS) is a number of components working together, usually a gun data computer, a director, and radar, which is designed to assist a ranged weapon system to target, track, and hit a target. It performs the same task as a human gunner firing a weapon, but attempts to do so faster and more accurately. Naval based fire control Origins The original fire-control systems were developed for ships. The early history of naval fire control was dominated by the engagement of targets within visual range (also referred to as direct fire). In fact, most naval engagements before 1800 were conducted at ranges of . Even during the American Civil War, the famous engagement between and was often conducted at less than range. Rapid technical improvements in the late 19th century greatly increased the range at which gunfire was possible. Rifled guns of much larger size firing explosive shells of lighter relative weight (compared to all-metal balls) so greatly increa ...
