AGTR
Technical research ships were used by the United States Navy during the 1960s to gather intelligence by monitoring, recording and analyzing wireless electronic communications of nations in various parts of the world. At the time these ships were active, the mission of the ships was covert and discussion of the true mission was prohibited (" classified information"). The mission of the ships was publicly given as conducting research into atmospheric and communications phenomena. However, the true mission was more or less an open secret and the ships were commonly referred to as " spy ships". Function These ships carried a crew of U.S. Navy personnel whose specialty was intercepting wireless electronic communications and gathering intelligence from those communications (signals intelligence, communications intelligence, and electronic signals intelligence ( SIGINT)). In the 1960s those personnel had a U.S. Navy rating of Communications Technician (later changed to Cryptologi ...

USS Liberty Incident
The USS ''Liberty'' incident was an attack on a United States Navy technical research ship (spy ship), , by Israeli Air Force jet fighter aircraft and Israeli Navy motor torpedo boats, on 8 June 1967, during the Six-Day War. The combined air and sea attack killed 34 crew members (naval officers, seamen, two marines, and one civilian NSA employee), wounded 171 crew members, and severely damaged the ship. At the time, the ship was in international waters north of the Sinai Peninsula, about northwest from the Egyptian city of Arish. Israel apologized for the attack, saying that the USS ''Liberty'' had been attacked in error after being mistaken for an Egyptian ship. Both the Israeli and U.S. governments conducted inquiries and issued reports that concluded the attack was a mistake due to Israeli confusion about the ship's identity. Others, including survivors of the attack, have rejected these conclusions and maintain that the attack was deliberate. In May 1968, the Israeli go ...

Spy Ship
A spy ship or reconnaissance vessel is a dedicated ship intended to gather intelligence, usually by means of sophisticated electronic eavesdropping. In a wider sense, any ship intended to gather information could be considered a spy ship. Spy ships are usually controlled by a nation's government, due to the high costs and advanced equipment required. They tend to be parts of the nation's navy, though they may also be operated by secret services. Naval trawlers masquerade as civilian ships such as fishing trawlers, which could be reasonably expected to remain in a certain area for a long time. Ships which are used to infiltrate spies or special forces are sometimes also called "spy ships". History An early version of what would become known as a spy ship is the United States civilian cargo ship , which made frequent voyages to Japan, China and the Philippines with cargo and passengers during the 1920s and 1930s. Starting in 1933 as a station ship she was assigned to monitor in ...

Victory Ship
The Victory ship was a class of cargo ship produced in large numbers by North American shipyards during World War II to replace losses caused by German submarines. They were a more modern design compared to the earlier Liberty ship, were slightly larger and had more powerful steam turbine engines giving higher speed to allow participation in high speed convoys and make them more difficult targets for German U-boats. A total of 531 Victory ships were built in between 1944 and 1946. VC2 design One of the first acts of the United States War Shipping Administration upon its formation in February 1942 was to commission the design of what came to be known as the Victory class. Initially designated EC2-S-AP1, where EC2 = Emergency Cargo, type 2 (Load Waterline Length between ), S = steam propulsion with AP1 = one aft propeller (EC2-S-C1 had been the designation of the Liberty ship design), it was changed to VC2-S-AP1 before the name "Victory Ship" was officially adopted on 28 Apr ...

Liberty Ship
Liberty ships were a class of cargo ship built in the United States during World War II under the Emergency Shipbuilding Program. Though British in concept, the design was adopted by the United States for its simple, low-cost construction. Mass-produced on an unprecedented scale, the Liberty ship came to symbolize U.S. wartime industrial output. The class was developed to meet British orders for transports to replace ships that had been lost. Eighteen American shipyards built 2,710 Liberty ships between 1941 and 1945 (an average of three ships every two days), easily the largest number of ships ever produced to a single design. Their production mirrored (albeit on a much larger scale) the manufacture of "Hog Islander" and similar standardized ship types during World War I. The immensity of the effort, the number of ships built, the role of female workers in their construction, and the survival of some far longer than their original five-year design life combine to make them th ...

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'' 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 Executive Order 9075 on 26 February 1942, 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 Afghanistan. The collective degree of valor (combat heroism) against an armed e ...

Hull Classification Symbol
The United States Navy, United States Coast Guard, and United States National Oceanic and Atmospheric Administration (NOAA) use a hull classification symbol (sometimes called hull code or hull number) to identify their ships by type and by individual ship within a type. The system is analogous to the pennant number system that the Royal Navy and other European and Commonwealth navies use. History United States Navy The U.S. Navy began to assign unique Naval Registry Identification Numbers to its ships in the 1890s. The system was a simple one in which each ship received a number which was appended to its ship type, fully spelled out, and added parenthetically after the ship's name when deemed necessary to avoid confusion between ships. Under this system, for example, the battleship ''Indiana'' was USS ''Indiana'' (Battleship No. 1), the cruiser ''Olympia'' was USS ''Olympia'' (Cruiser No. 6), and so on. Beginning in 1907, some ships also were referred to alternatively ...

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 ...

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 ...

Ship Decommissioning
Ship commissioning is the act or ceremony of placing a ship in active service and may be regarded as a particular application of the general concepts and practices of project commissioning. The term is most commonly applied to placing a warship in active duty with its country's military forces. The ceremonies involved are often rooted in centuries-old naval tradition. Ship naming and launching endow a ship hull with her identity, but many milestones remain before she is completed and considered ready to be designated a commissioned ship. The engineering plant, weapon and electronic systems, galley, and other equipment required to transform the new hull into an operating and habitable warship are installed and tested. The prospective commanding officer, ship's officers, the petty officers, and seamen who will form the crew report for training and familiarization with their new ship. Before commissioning, the new ship undergoes sea trials to identify any deficiencies needing correct ...

Helicopter Carrier
A helicopter carrier is a type of aircraft carrier whose primary purpose is to operate helicopters, and has a large flight deck that occupies a substantial part of the deck, which can extend the full length of the ship like of the Royal Navy (RN), or extend only partway, usually aft, as in the Soviet Navy's or in the Chinese Navy's Type 0891A. It often also has a hangar deck for the storage of aircraft. Pure helicopter carriers are difficult to define in the 21st century. The advent of STOVL aircraft such as the Harrier jump jet, and now the F-35, have complicated the classification; the United States Navy's , for instance, carries six to eight Harriers as well as over 20 helicopters. Only smaller carriers unable to operate the Harrier and older pre-Harrier-era carriers can be regarded as true helicopter carriers. In many cases, other carriers, able to operate STOVL aircraft, are classified as " light aircraft carriers". Other vessels, such as the ''Wasp'' class, are also ca ...
