Columbia-class Submarine
The ''Columbia''-class submarine (formerly known as the ''Ohio'' Replacement Submarine and SSBN-X Future Follow-on Submarine) is an upcoming class of nuclear submarines designed to replace the ballistic missile submarines in the United States Navy. The first submarine officially began construction on 1 October 2020, and is scheduled to enter service in 2031. On 3 June 2022, the Navy announced that this first boat will be named USS ''District of Columbia'' (SSBN-826), because there currently exists an attack submarine named USS ''Columbia'' (SSN-771). The Navy did not say whether the name of the class will also be changed. Overview The ''Columbia'' class is to replace the Ohio class of UGM-133 Trident II–armed ballistic missile submarines, whose remaining boats are to be decommissioned, one per year, beginning in 2027. The ''Columbia'' class will take over the role of submarine presence in the United States’ strategic nuclear force. Electric Boat designed the new class wi ...

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] |
Lead Ship
The lead ship, name ship, or class leader is the first of a series or class of ships all constructed according to the same general design. The term is applicable to naval ships and large civilian vessels. Large ships are very complex and may take as many as five to ten years to build. Improvements based on experience with building and operating the lead ship are likely to be incorporated into the design or construction of later ships in the class, so it is rare to have vessels that are identical. The second and later ships are often started before the first one is completed, launched and tested. Nevertheless, building copies is still more efficient and cost-effective than building prototypes, and the lead ship will usually be followed by copies with some improvements rather than radically different versions. The improvements will sometimes be retrofitted to the lead ship. Occasionally, the lead ship will be launched and commissioned for shakedown testing before following s ...

Anechoic Tile
__NOTOC__ Anechoic tiles are rubber or synthetic polymer tiles containing thousands of tiny voids, applied to the outer hulls of military ships and submarines, as well as anechoic chambers. Their function is twofold: *To absorb the sound waves of active sonar, reducing and distorting the return signal, thereby reducing its effective range. *To attenuate the sounds emitted from the vessel, typically its engines, to reduce the range at which it can be detected by passive sonar. Development in the Third Reich The technology of anechoic tiles was developed by the ''Kriegsmarine'' during the Second World War, codenamed ''Alberich'' after the invisible guardian dwarf of the Rhinegold treasure from Richard Wagner's Der Ring des Nibelungen music dramas. The coating consisted of sheets approximately square and thick, with rows of holes in two sizes, and in diameter. Manufactured by IG Farben as a specially formed synthetic rubber tile and made using a stabilized, non-polar, hi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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.

Congressional Budget Office
The Congressional Budget Office (CBO) is a List of United States federal agencies, federal agency within the United States Congress, legislative branch of the United States government that provides budget and economic information to Congress. Inspired by California's California Legislative Analyst's Office, Legislative Analyst's Office that manages the state budget in a strictly nonpartisan fashion, the CBO was created as a nonpartisan agency by the Congressional Budget and Impoundment Control Act of 1974. Whereas politicians on both sides of the aisle have criticized the CBO when its estimates have been politically inconvenient, economists and other academics overwhelmingly reject that the CBO is partisan or that it fails to produce credible forecasts. There is a consensus among economists that "adjusting for legal restrictions on what the CBO can assume about future legislation and events, the CBO has historically issued credible forecasts of the effects of both Democratic and R ...
