Hughes Mining Barge
The ''Hughes Mining Barge'', or ''HMB-1'', is a submersible barge about 99 m (324 ft) long, 32 m (106 ft) wide, and more than 27 m (90 ft) tall. The ''HMB-1'' was originally developed as part of Project Azorian (more widely, but erroneously, known as "Project Jennifer"), the top-secret effort mounted by the Central Intelligence Agency to salvage the wreckage of the Soviet submarine ''K-129'' from the ocean floor. The ''HMB-1'' was designed to allow the device that would be used to grasp and lift the submarine to be constructed inside the barge and out of sight, and to be installed in the ''Glomar Explorer'' in secrecy. This was done by towing the ''HMB-1'', with the capture device inside, to a location near Catalina Island (off the coast of California), and then submerging it onto stabilizing piers that had been installed on the seafloor. The ''Glomar Explorer'' was then maneuvered over the ''HMB-1'', the retractable roof was opened, and the captur ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Treasure Island, San Francisco
Treasure Island is an artificial island in the San Francisco Bay and a neighborhood in the City and County of San Francisco. Built in 1936–37 for the 1939 Golden Gate International Exposition, the island's World's Fair site is a California Historical Landmark. Buildings there have been listed on the National Register of Historic Places, and the historical Naval Station Treasure Island, an auxiliary air facility (for airships, blimps, dirigibles, planes and seaplanes), are designated in the Geographic Names Information System. Geography The San Francisco census tract that includes Treasure Island extends up and down the San Francisco Bay and includes a small uninhabited tip of western Alameda Island. Yerba Buena and Treasure islands together have a land area of with – in 2010 – a total population of 2,500. Treasure Island alone is 393 acres.

United States Dollar
The United States dollar ( symbol: $; code: USD; also abbreviated US$ or U.S. Dollar, to distinguish it from other dollar-denominated currencies; referred to as the dollar, U.S. dollar, American dollar, or colloquially buck) is the official currency of the United States and several other countries. The Coinage Act of 1792 introduced the U.S. dollar at par with the Spanish silver dollar, divided it into 100 cents, and authorized the minting of coins denominated in dollars and cents. U.S. banknotes are issued in the form of Federal Reserve Notes, popularly called greenbacks due to their predominantly green color. The monetary policy of the United States is conducted by the Federal Reserve System, which acts as the nation's central bank. The U.S. dollar was originally defined under a bimetallic standard of (0.7735 troy ounces) fine silver or, from 1837, fine gold, or $20.67 per troy ounce. The Gold Standard Act of 1900 linked the dollar solely to gold. From 1934, it ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Alameda, California
Alameda ( ; ; Spanish for "Avenue (landscape), tree-lined path") is a city in Alameda County, California, located in the East Bay (San Francisco Bay Area), East Bay region of the Bay Area. The city is primarily located on Alameda (island), Alameda Island, but also spans Bay Farm Island, Alameda, California, Bay Farm Island and Coast Guard Island, as well as a few other smaller islands in San Francisco Bay. The city's estimated population in 2019 was 77,624. History Spanish & Mexican era Alameda occupies what was originally a peninsula connected to Oakland. Much of it was low-lying and marshy. The higher ground nearby and adjacent parts of what is now downtown Oakland were the site of one of the largest coastal oak forests in the world. Spanish colonists called the area ''Encinal'', meaning "forest of evergreen oak". ''Alameda'' is Spanish for "grove of poplar trees" or "tree-lined avenue." It was chosen as the name of the city in 1853 by popular vote. The inhabitants at the ti ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Stealth Ship
A stealth ship is a ship that employs stealth technology construction techniques in an effort to make it harder to detect by one or more of radar, visual, sonar, and infrared methods. These techniques borrow from stealth aircraft technology, although some aspects such as wake and acoustic signature reduction (acoustic quieting) are unique to stealth ships' design. Although radar cross-section (RCS) reduction is a fairly new concept, many other forms of masking a ship have existed for centuries or even millennia. Shaping In designing a ship with a reduced radar signature, the main concerns are radar beams originating near or slightly above the horizon (as seen from the ship) coming from distant patrol aircraft, other ships, or sea-skimming anti-ship missiles with active radar seekers. Therefore, the shape of the ship avoids vertical surfaces, which are effective at reflecting such beams directly back to the emitter. Retro-reflective right angles are eliminated to avoid the ...

Sea Shadow
''Sea Shadow'' (IX-529) was an experimental stealth ship built by Lockheed for the United States Navy to determine how a low radar profile might be achieved and to test high stability hull configurations that have been used in oceanographic ships. Development ''Sea Shadow'' was built in 1984 to examine the application of stealth technology on naval vessels, and was used in secret until a public debut in 1993. In addition, the ship was designed to test the use of automation to reduce crew size. The ship was created by the Defense Advanced Research Projects Agency (DARPA), the U.S. Navy and Lockheed. ''Sea Shadow'' was developed and built at Lockheed's Redwood City, California facility, inside the Hughes Mining Barge (HMB-1), which functioned as a floating drydock during construction and testing. History ''Sea Shadow'' had a SWATH (small-waterplane-area twin hull) design. Below the water were submerged twin hulls, each with a propeller, aft stabilizer, and inboard hydrofoil. T ...

Sea Trial
A sea trial is the testing phase of a watercraft (including boats, ships, and submarines). It is also referred to as a " shakedown cruise" by many naval personnel. It is usually the last phase of construction and takes place on open water, and it can last from a few hours to many days. Sea trials are conducted to measure a vessel's performance and general seaworthiness. Testing of a vessel's speed, maneuverability, equipment and safety features are usually conducted. Usually in attendance are technical representatives from the builder (and from builders of major systems), governing and certification officials, and representatives of the owners. Successful sea trials subsequently lead to a vessel's certification for commissioning and acceptance by its owner. Although sea trials are commonly thought to be conducted only on new-built vessels (referred by shipbuilders as 'builders trials'), they are regularly conducted on commissioned vessels as well. In new vessels, they are used ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Drydock
A dry dock (sometimes drydock or dry-dock) is a narrow basin or vessel that can be flooded to allow a load to be floated in, then drained to allow that load to come to rest on a dry platform. Dry docks are used for the construction, maintenance, and repair of ships, boats, and other watercraft. History Greco-Roman world The Greek author Athenaeus of Naucratis (V 204c-d) reports something that may have been a dry dock in Ptolemaic Egypt in the reign of Ptolemy IV Philopator (221-204 BC) on the occasion of the launch of the enormous ''Tessarakonteres'' rowing ship. It has been calculated that a dock for a vessel of such a size might have had a volume of 750,000 gallons of water. In Roman times, a shipyard at Narni, which is still studied, may have served as a dry dock. Medieval China The use of dry docks in China goes at least as far back the 10th century A.D. In 1088, Song Dynasty scientist and statesman Shen Kuo (1031–1095) wrote in his '' Dream Pool Essays'': Renais ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
