DSV Turtle
''Turtle'' (DSV-3) was a 16-ton, crewed deep-ocean research submersible owned by the United States Navy. It is sister to ''Alvin'' (DSV-2) and ''Sea Cliff'' (DSV-4). History ''Turtle'' (DSV-3) was designed and built by the Electric Boat division of General Dynamics Corporation at Groton, Connecticut. Turtle and her sister ''Sea Cliff'' (DSV-4) were launched on December 11, 1968. Turtle was named after Turtle Town, a small community in Polk County, Tennessee. Her name also pays tribute to the American submarine ''Turtle'' which served in the American Revolution. ''Turtle'' was accepted by the US Navy on September 25, 1970 at Woods Hole, Massachusetts. ''Turtle'' was designed to dive to 6500 feet. When DSV-2 ''Alvin'' installed a new titanium hull, the ''Alvin'' steel hull was installed in the ''Turtle''. The original steel hull was acquired by the Mariners' Museum and Park in 2000 and became a part of the exhibition. The ''Turtle'' depth rating was then increased to 10,000 f ...

Turtle DSV-3
Turtles are an order of reptiles known as Testudines, characterized by a special shell developed mainly from their ribs. Modern turtles are divided into two major groups, the Pleurodira (side necked turtles) and Cryptodira (hidden necked turtles), which differ in the way the head retracts. There are 360 living and recently extinct species of turtles, including land-dwelling tortoises and freshwater terrapins. They are found on most continents, some islands and, in the case of sea turtles, much of the ocean. Like other amniotes (reptiles, birds, and mammals) they breathe air and do not lay eggs underwater, although many species live in or around water. Turtle shells are made mostly of bone; the upper part is the domed carapace, while the underside is the flatter plastron or belly-plate. Its outer surface is covered in scales made of keratin, the material of hair, horns, and claws. The carapace bones develop from ribs that grow sideways and develop into broad flat plates that ...

Naval Vessel Register
The ''Naval Vessel Register'' (NVR) is the official inventory of ships and service craft in custody of or titled by the United States Navy. It contains information on ships and service craft that make up the official inventory of the Navy from the time a vessel is authorized through its life cycle and disposal. It also includes ships that have been removed from the register (often termed '' stricken'' or ''struck''), but not disposed of by sale, transfer to another government, or other means. Ships and service craft disposed of prior to 1987 are currently not included, but are gradually being added along with other updates. History The NVR traces its origin back to the 1880s, having evolved from several previous publications. In 1911, the Bureau of Construction and Repair published ''Ships Data US Naval Vessels'', which subsequently became the ''Ships Data Book'' in 1952 under the Bureau of Ships. The Bureau of Ordnance's ''Vessel Register'', first published in 1942 and retitl ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Alvin-class Deep-submergence Vehicles
A deep-submergence vehicle (DSV) is a deep-diving crewed submersible that is self-propelled. Several navies operate vehicles that can be accurately described as DSVs. DSVs are commonly divided into two types: research DSVs, which are used for exploration and surveying, and DSRVs (Deep Submergence Rescue Vehicle), which can be used for rescuing the crew of a sunken navy submarine, clandestine (espionage) missions (primarily installing wiretaps on undersea communications cables), or both. DSRVs are equipped with docking chambers to allow personnel ingress and egress via a manhole. The real-life feasibility of any DSRV-based rescue attempt is hotly debated, because the few available docking chambers of a stricken submarine may be flooded, trapping the sailors still alive in other dry compartments. The only attempt to rescue a stricken submarine with these so far (the Russian submarine ''Kursk'') ended in failure as the entire crew who survived the explosion had either suffocated or ...

Naval Sea Systems Command
The Naval Sea Systems Command (NAVSEA) is the largest of the United States Navy's five "systems commands," or materiel (not to be confused with "material") organizations. From a physical perspective, NAVSEA has four shipyards for shipbuilding, conversion, and repair, ten "warfare centers" (two undersea and eight surface), the NAVSEA headquarters, located at the Washington Navy Yard, in Washington D.C., and other locations in 15 states and 3 overseas continents. NAVSEA's primary objective is to engineer, build, buy, and maintain the U.S. Navy's fleet of ships and its combat systems. NAVSEA's budget of almost $30 billion accounts for nearly one quarter of the Navy's entire budget, with more than 80,200 personnel and 150 acquisition programs under its oversight. History The origin of NAVSEA dates to 1794, when Commodore John Barry was charged to oversee the construction of a 44-gun frigate and ensure that all business "harmonized and conformed" to the public's interest.

DSV-5 Nemo
DSV-5, ex-NEMO (Naval Experimental Manned Observatory), was a submersible used by the United States Navy between 1970 and 1986 to oversee and observe undersea construction work. NEMO had a spherical transparent acrylic hull, which gave occupants panoramic vision. NEMO was the first submersible with a hull made entirely out of transparent acrylic (Plexiglass), and much of her career was spent testing this hull design. NEMO was found to be an effective observation platform, despite not being able to hover in place, and acrylic-hulled submersibles have continued to be built and operated in the United States. NEMO is considered part of the ''Alvin'' class of Deep Submergence Vehicles despite bearing little resemblance to the other subs of the class. NEMO was transferred to "other government agencies" (likely the CIA) in 1986 and retired from government service in 2011. It was then given to the U.S. Navy Seabee Museum, where it remains on display. Design NEMO consisted of a spherical ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

National Defense Service Medal
The National Defense Service Medal (NDSM) is a service award of the United States Armed Forces established by President Dwight D. Eisenhower in 1953. It is awarded to every member of the US Armed Forces who has served during any one of four specified periods of armed conflict or national emergency from June 27, 1950 through the present. Combat or "in theater" service is not a requirement for the award. History The National Defense Service Medal (NDSM) was first intended to be a "blanket campaign medal" awarded to service members who served honorably during a designated time period of when a "national emergency" had been declared during a time of war or conflict. It may also be issued to active military members for any other period that the Secretary of Defense designates. To date, the NDSM has been awarded for four specific time periods, which roughly correspond to the Korean (1950-1954), Vietnam (1961-1974), Gulf (1990-1995), and the Global War on Terrorism (2001 to 2022). ...

Mystic, Connecticut
Mystic is a village and census-designated place (CDP) in Groton, Connecticut, Groton and Stonington, Connecticut, United States. Historically, Mystic was a significant Connecticut seaport with more than 600 ships built over 135 years starting in 1784. Mystic Seaport, one of the largest maritime museums in the United States, has preserved a number of sailing ships, such as the whaling ship ''Charles W. Morgan (ship), Charles W. Morgan''. The village is located on the Mystic River (Connecticut), Mystic River, which flows into Fishers Island Sound and by extension Long Island Sound and the Atlantic Ocean. The Mystic River Bascule Bridge crosses the river in the center of the village.

Submarine Development Group 1
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 spec ...
