Operation Sand Dollar
Project Azorian (also called "Jennifer" by the press after its Top Secret Security Compartment) was a U.S. Central Intelligence Agency (CIA) project to recover the sunken Soviet submarine ''K-129'' from the Pacific Ocean floor in 1974 using the purpose-built ship ''Hughes Glomar Explorer''.Wiegley, Roger D., LT (JAG) USN "The Recovered Sunken Warship: Raising a Legal Question" ''United States Naval Institute Proceedings'' January 1979 p. 30. The 1968 sinking of ''K-129'' occurred about northwest of Hawaii. Project Azorian was one of the most complex, expensive, and covert intelligence operations of the Cold War at a cost of about $800 million, or $ billion today. The US designed the recovery ship and its lifting cradle using concepts developed with Global Marine (see Project Mohole) that used their precision stability equipment to keep the ship nearly stationary above the target while lowering nearly of pipe. They worked with scientists to develop methods for preserving pa ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Glomar Explorer
''GSF Explorer'', formerly USNS ''Hughes Glomar Explorer'' (T-AG-193), was a deep-sea drillship platform built for Project Azorian, the secret 1974 effort by the United States Central Intelligence Agency's Special Activities Division to recover the Soviet submarine ''K-129''. Construction The ship was built as ''Hughes Glomar Explorer'' in 1971 and 1972 by Sun Shipbuilding & Drydock Company for more than (about $ billion in ) at the direction of Howard Hughes for use by his company, Global Marine Development Inc. It began operation on 20 June 1974. The ship's construction required a purpose-built crane ship, '' Sun 800'', to lift its 630-ton gimbal into place. Hughes told the media that the ship's purpose was to extract manganese nodules from the ocean floor. This marine geology cover story became surprisingly influential, causing many others to examine the idea.

Presidential Unit Citation (United States)
The Presidential Unit Citation (PUC), originally called the Distinguished Unit Citation, is awarded to units of the uniformed services of the United States, and those of allied countries, for extraordinary heroism in action against an armed enemy on or after 7 December 1941 (the date of the Attack on Pearl Harbor and the start of American involvement in World War II). The unit must display such gallantry, determination, and ''Esprit de Corps (morale), esprit de corps'' in accomplishing its mission under extremely difficult and hazardous conditions so as to set it apart from and above other units participating in the same campaign. Since its inception by President Franklin D. Roosevelt with the signing of s:Executive Order 9075, Executive Order 9075 on 26 February 1942, Retroactive legislation, retroactive to 7 December 1941, to 2008, the Presidential Unit Citation has been awarded in conflicts such as World War II, the Korean War, the Vietnam War, Iraq War, and the War in Afgh ...

Pearl Harbor
Pearl Harbor is an American lagoon harbor on the island of Oahu, Hawaii, west of Honolulu. It was often visited by the naval fleet of the United States, before it was acquired from the Hawaiian Kingdom by the U.S. with the signing of the Reciprocity Treaty of 1875. Much of the harbor and surrounding lands are now a United States Navy deep-water naval base. It is also the headquarters of the United States Pacific Fleet. The U.S. government first obtained exclusive use of the inlet and the right to maintain a repair and coaling station for ships here in 1887. The Attack on Pearl Harbor, surprise attack on the harbor by the Imperial Japanese Navy on December 7, 1941, led the United States to United States declaration of war on Japan, declare war on the Empire of Japan, marking the American entry into World War II, United States' entry into World War II. History Pearl Harbor was originally an extensive shallow embayment called ''Wai Momi'' (meaning 'Waters of Pearl') or ''Puuloa' ...

Model Of The Sunken And Deteriorated K-129 Submarine Was Created By The CIA During The AZORIAN Mission That Has Never Been Displayed Before At The CIA Museum In 2022
A model is an informative representation of an object, person, or system. The term originally denoted the plans of a building in late 16th-century English, and derived via French and Italian ultimately from Latin , . Models can be divided into physical models (e.g. a ship model or a fashion model) and abstract models (e.g. a set of mathematical equations describing the workings of the atmosphere for the purpose of weather forecasting). Abstract or conceptual models are central to philosophy of science. In scholarly research and applied science, a model should not be confused with a theory: while a model seeks only to represent reality with the purpose of better understanding or predicting the world, a theory is more ambitious in that it claims to be an explanation of reality. Types of model ''Model'' in specific contexts As a noun, ''model'' has specific meanings in certain fields, derived from its original meaning of "structural design or layout": * Model (art), a person ...

International Date Line
The International Date Line (IDL) is the line extending between the South and North Poles that is the boundary between one calendar day and the next. It passes through the Pacific Ocean, roughly following the 180.0° line of longitude and deviating to pass around some territories and island groups. Crossing the date line eastbound decreases the date by one day, while crossing the date line westbound increases the date. The line is a cartographic convention and is not defined by international law. This has made it difficult for cartographers to agree on its precise course and has allowed countries through whose waters it passes to move it at times for their convenience. Geography Circumnavigating the globe People traveling westward around the world must set their clocks: *Back by one hour for every 15° of longitude crossed, and *Forward by 24 hours upon crossing the International Date Line. People traveling eastward must set their clocks: *Forward by one hour for e ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Naval Facility Point Sur
Naval Facility Point Sur was one of 30 secret sites worldwide that were built during the Cold War to detect Soviet submarines. In 1958, the U.S. Navy built a Naval Facility ½ mile south of Point Sur on the Big Sur coast to provide submarine surveillance using the classified SOund SUrveillance System (SOSUS). The public was told the station was engaged in oceanographic research. Long-range acoustic listening was first tested and partially developed at Point Sur light station with an associated SOFAR station. The facility was one of the stand-alone SOSUS stations around the world. NAVFAC Point Sur played a key role in identifying the location of the wrecked Soviet submarine Soviet submarine ''K-129'', a portion of which was eventually raised in a significant intelligence coup. The NAVFAC was closed in 1984, when its operations were computerized and its data transmitted to another location. All but one building was donated to California State Parks in 2000, which used some of t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Hydrophone
A hydrophone () is a microphone designed for underwater use, for recording or listening to underwater sound. Most hydrophones contains a piezoelectric transducer that generates an electric potential when subjected to a pressure change, such as a sound wave. A hydrophone can also detect airborne sounds but is insensitive of them because it is designed to match the acoustic impedance of water, a denser fluid than air. Sound travels 4.3 times faster in water than in air, and a sound wave in water exerts a pressure 60 times more than what is exerted by a wave of the same amplitude in air. Similarly, a standard microphone can be buried in the ground, or immersed in water if it is put in a waterproof container but will give poor performance because of the similarly-bad acoustic impedance match. History The first hydrophones consisted of a tube with a thin membrane covering the submerged end and the observer's ear of the equipment. The design of effective hydrophones must take into a ...
