USS Oxford (AGTR-1)
USS ''Oxford'' (AGTR-1/AG-159) was an ''Oxford''-class technical research ship (a class of US spy ships of the early Cold War), acquired by the U.S. Navy in 1960 and converted for the task of conducting "research in the reception of electromagnetic propagations" (electronic signals intelligence gathering). She was originally built during World War II as a Liberty-type cargo ship originally named the ''Samuel R. Aitken''. ''Samuel R. Aitken'''s civilian life The second ship eventually to be named ''Oxford'' by the Navy, ''AGTR-1'', a Liberty ship, was laid down 23 June 1945 under Maritime Commission contract by the New England Shipbuilding Corp. of Portland, Maine as a merchant marine naval cargo ship; launched 31 July 1945 as ''Samuel R.

National Defense Reserve Fleet
The National Defense Reserve Fleet (NDRF) consists of ships of the United States of America, mostly merchant vessels, that have been "mothballed" but can be activated within 20 to 120 days to provide shipping during national military emergencies, or non-military emergencies such as commercial shipping crises. The NDRF is managed by the U.S. Department of Transportation's Maritime Administration (MARAD). It is distinct from the United States Navy reserve fleets, which consist largely of warships. NDRF vessels are at the fleet sites at James River, Virginia (James River Reserve Fleet); Beaumont, Texas (Beaumont Reserve Fleet); and Suisun Bay, California (Suisun Bay Reserve Fleet); and at designated outported berths. Former anchorage sites included Stony Point, New York (Hudson River Reserve Fleet); Wilmington, North Carolina; Mobile, Alabama; Astoria, Oregon; and Olympia, Washington. Through the 2010s, the oldest, most decrepit hulls at Suisun Bay were stripped of toxic ma ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
SIGINT
Signals intelligence (SIGINT) is intelligence-gathering by interception of ''signals'', whether communications between people (communications intelligence—abbreviated to COMINT) or from electronic signals not directly used in communication (electronic intelligence—abbreviated to ELINT). Signals intelligence is a subset of intelligence collection management. As classified and sensitive information is usually encrypted, signals intelligence in turn involves the use of cryptanalysis to decipher the messages. Traffic analysis—the study of who is signaling whom and in what quantity—is also used to integrate information again. History Origins Electronic interceptions appeared as early as 1900, during the Boer War of 1899–1902. The British Royal Navy had installed wireless sets produced by Marconi on board their ships in the late 1890s, and the British Army used some limited wireless signalling. The Boers captured some wireless sets and used them to make vital transmissi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Military Intelligence
Military intelligence is a military discipline that uses information collection and analysis approaches to provide guidance and direction to assist commanders in their decisions. This aim is achieved by providing an assessment of data from a range of sources, directed towards the commanders' mission requirements or responding to questions as part of operational or campaign planning. To provide an analysis, the commander's information requirements are first identified, which are then incorporated into intelligence collection, analysis, and dissemination. Areas of study may include the operational environment, hostile, friendly and neutral forces, the civilian population in an area of combat operations, and other broader areas of interest. Intelligence activities are conducted at all levels, from tactical to strategic, in peacetime, the period of transition to war, and during a war itself. Most governments maintain a military intelligence capability to provide analytical and i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Open Secret
An open secret is a concept or idea that is "officially" (''de jure'') secret or restricted in knowledge, but in practice (''de facto'') is widely known; or it refers to something that is widely known to be true but which none of the people most intimately concerned are willing to categorically acknowledge in public. Popular examples Government and military One famous "open secret" is that of Area 51, a United States military base containing an aircraft testing facility. The U.S. government did not explicitly affirm the existence of any military facility near Groom Lake, Lincoln County, Nevada, until 2013, when the CIA released documents revealing that the site was established to test spy planes. While the general location of the base is now officially acknowledged, the base does not appear on government maps or in declassified satellite photography. Yet despite this, the base was demonstrably and widely acknowledged to exist for many years before the CIA officially confirmed i ...

Electromagnetic Radiation
In physics, electromagnetic radiation (EMR) consists of waves of the electromagnetic field, electromagnetic (EM) field, which propagate through space and carry momentum and electromagnetic radiant energy. It includes radio waves, microwaves, infrared, Light, (visible) light, ultraviolet, X-rays, and gamma rays. All of these waves form part of the electromagnetic spectrum. Classical electromagnetism, Classically, electromagnetic radiation consists of electromagnetic waves, which are synchronized oscillations of electric field, electric and magnetic fields. Depending on the frequency of oscillation, different wavelengths of electromagnetic spectrum are produced. In a vacuum, electromagnetic waves travel at the speed of light, commonly denoted ''c''. In homogeneous, isotropic media, the oscillations of the two fields are perpendicular to each other and perpendicular to the direction of energy and wave propagation, forming a transverse wave. The position of an electromagnetic wave w ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

The city was besieged during The Anarchy in 1142. The university rose to dom ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
United States Ship
United States Ship (abbreviated as USS or U.S.S.) is a ship prefix used to identify a commissioned ship of the United States Navy and applies to a ship only while it is in commission. Before commissioning, the vessel may be referred to as a " pre-commissioning unit" (PCU), but is officially referred to by name with no prefix. After decommissioning, it is referred to by name with no prefix, though people commonly refer to those ships with the prefix "ex-", as in ex-''ship name''. In-service but non-commissioned Navy ships go by the prefix USNS, which stands for United States Naval Ship. From the early beginnings of the U.S. Navy there had been no standard method of referring to U.S. Navy ships until 1907 when President Theodore Roosevelt issued Executive Order 549 on 8 January stating that all U.S. Navy ships were to be referred to as "The name of such vessel, preceded by the words, United States Ship, or the letters U.S.S., and by no other words or letters".
