Made in 1954 as the U.S. Navy entered the nuclear submarine era, “Take ‘Er Down” celebrates the history of the submarine. At :55, the new submarine USS Nautilus is shown on the launching ways. At 1:10 the Navy’s first diesel submarine USS Holland is shown in operation. At 1:28 the L and K class boats of WWI are shown, and then R and S class boats. At 1:57 the outbreak of WWII at Pearl Harbor is shown, and then a brief history of the submarine force operating in the Pacific from 1942-1945. As torpedoes wreak havoc on Japanese shipping, various improvements are shown including new radar and sonar, and improved silent electric torpedoes. At 3:20 training simulation is seen. At 4:20 some of the benefits of serving in the “Silent Service” are shown including great food, camaraderie, and of course no showers for weeks at sea. At 5:00 Navy psychologists assess potential crewmembers. At 5:22 the submarine school at New London is shown. At 6:40 drills are shown at sea including crash diving. At 8:13 the escape training tower is shown. At 8:25 newly minted submariners arrive on their new boat. At 8:40 the USS Spinax radar picket boat is shown. At 8:55 USS Tunny (actually probably USS Cusk) is shown launching a V-1 rocket. At 9:09 the K1, a hunter-killer boat, is shown. At 9:24 a submarine makes an emergency surface. At 9:37 the USS Perch with an amphibious hangar on the rear of the sub is shown. At 9:45 a helicopter takes off from Perch as part of work with the UDTs. At 9:57 the UDT assault party is shown. At 11:04 the Balao class USS Cubera SS-347 is shown after GUPPY class conversion. At 11:10 a snorkel is shown in operation allowing running of the diesels without surfacing. At 11:30 an atomic bomb explodes as part of Operation Crossroads. Now the nuclear submarine USS Nautilus is shown at 11:50. The submarine harnesses the power of the atom.

World's Most Powerful & Deadly Super Submarine – USS Texas – Full Documentary

World Most Feared Super Submarine in U.S, Navy – The Virginia Class attack submarine is the U.S. Navy’s newest undersea warfare platform and incorporates the latest in stealth, intelligence gathering and weapons systems technology. Attack submarines are designed to seek and destroy enemy submarines and surface ships; project power ashore with Tomahawk cruise missiles and Special Operation Forces; carry out Intelligence, Surveillance, and Reconnaissance (ISR) missions; support battle group operations; and engage in mine warfare.

The Virginia class wa not the first new design to come into service after the Cold War. The Seawolf class was originally intended to succeed the Los Angeles class, but production was canceled after only three submarines were produced. This restriction occurred due to budgeting restraints at the end of the Cold War, and the final submarine was manufactured in 1995. At a cost of $3 billion per unit, the Seawolf class was the most expensive SSN submarine. The Virginia class was put into production in full swing due to being smaller and carrying more manageable costs than the Seawolf.

The Navy is now building the next-generation attack submarine, the Virginia (SSN 774) class. The Virginia class has several innovations that significantly enhance its warfighting capabilities with an emphasis on littoral operations. Virginia class SSNs have a fly-by-wire ship control system that provides improved shallow-water ship handling. The class has special features to support special operation forces including a reconfigurable torpedo room which can accommodate a large number of special operation forces and all their equipment for prolonged deployments and future off-board payloads.

The class also has a large lock-in/lock-out chamber for divers. In Virginia-class SSNs, traditional periscopes have been supplanted by two photonics masts that host visible and infrared digital cameras atop telescoping arms. With the removal of the barrel periscopes, the ship’s control room has been moved down one deck and away from the hull’s curvature, affording it more room and an improved layout that provides the commanding officer with enhanced situational awareness. Additionally, through the extensive use of modular construction, open architecture, and commercial off-the-shelf components, the Virginia class is designed to remain state of the practice for its entire operational life through the rapid introduction of new systems and payloads.

As part of the Virginia-class’ third, or Block III, contract, the Navy redesigned approximately 20 percent of the ship to reduce their acquisition costs. Most of the changes are found in the bow where the traditional, air-backed sonar sphere has been replaced with a water-backed Large Aperture Bow (LAB) array which reduces acquisition and life-cycle costs while providing enhanced passive detection capabilities. The new bow also replaces the 12 individual Vertical Launch System (VLS) tubes with two 87-inch Virginia Payload Tubes (VPTs), each capable of launching six Tomahawk cruise missiles. The VPTs simplify construction, reduce acquisition costs, and provide for more payload flexibility than the smaller VLS tubes due to their added volume.

USS ( United States Ship ), typically as a ship prefix in the United States Navy (includes submarines)

A submarine is a watercraft capable of independent operation underwater. It differs from a submersible, which has more limited underwater capability. The term most commonly refers to a large, crewed, autonomous vessel. It 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. Used as an adjective in phrases such as submarine cable, submarine means “under the sea”. The noun submarine evolved as a shortened form of submarine boat (and is often further shortened to sub).[1] For reasons of naval tradition, submarines are usually referred to as “boats” rather than as “ships”, regardless of their size.

Although experimental submarines had been built before, submarine design took off during the 19th century, and they were adopted by several navies. Submarines were first widely used during World War I (1914–1918), and now figure in many navies large and small. Military usage includes attacking enemy surface ships (merchant and military), submarines, aircraft carrier protection, blockade running, ballistic missile submarines as part of a nuclear strike force, reconnaissance, conventional land attack (for example using a cruise missile), and covert insertion of special forces. Civilian uses for submarines include marine science, salvage, exploration and facility inspection and maintenance. Submarines can also be modified to perform more specialized functions such as search-and-rescue missions or undersea cable repair. Submarines are also used in tourism, and for undersea archaeology.

Nuclear submarine

A nuclear submarine is a submarine powered by a nuclear reactor. The performance advantages of nuclear submarines over “conventional” (typically diesel-electric) submarines are considerable. Nuclear propulsion, being completely independent of air, frees the submarine from the need to surface frequently, as is necessary for conventional submarines. The large amount of power generated by a nuclear reactor allows nuclear submarines to operate at high speed for long periods of time; and the long interval between refuelings grants a range limited only by consumables such as food.

Megastructures is a documentary television series appearing on the National Geographic Channel in the United States and the United Kingdom, Channel 5 in the United Kingdom, France 5 in France, and 7mate in Australia.

Each episode is an educational look of varying depth into the construction, operation, and staffing of various structures or construction projects, but not ordinary construction products.

Generally containing interviews with designers and project managers, it presents the problems of construction and the methodology or techniques used to overcome obstacles. In some cases (such as the Akashi-Kaikyo Bridge and Petronas Towers) this involved the development of new materials or products that are now in general use within the construction industry.

Megastructures focuses on constructions that are extreme; in the sense that they are the biggest, tallest, longest, or deepest in the world. Alternatively, a project may appear if it had an element of novelty or are a world first (such as Dubai’s Palm Islands). This type of project is known as a Megaproject.
