Fleet Sonar School
The Fleet Sonar School was a United States Navy facility located at Naval Station Key West, Florida for the training of Service personnel in Sonar techniques and equipment, and Anti-submarine warfare. The facility opened in 1940, after personnel were transferred from the existing Atlantic Fleet Sound School in New London, Connecticut, which had opened in 1939. The school was invaluable for training sonar operators for the country's struggle against German U-boats a few years later, followed by training in the tracking of Soviet Navy submarines during the Cold War.

Underwater Telephone
Underwater acoustic communication is a technique of sending and receiving messages below water. There are several ways of employing such communication but the most common is by using hydrophones. Underwater communication is difficult due to factors such as multi-path radio propagation, propagation, time variations of the channel, small available bandwidth and strong attenuation, signal attenuation, especially over long ranges. Compared to terrestrial communication, underwater communication has low data rates because it uses acoustic waves instead of electromagnetic waves. At the beginning of the 20th century some ships communicated by underwater bells as well as using the system for navigation. Submarine signals were at the time competitive with the primitive maritime radionavigation. The later Fessenden oscillator allowed communication with submarines. Types of modulation used for underwater acoustic communications In general the modulation methods developed for radio communic ...

Navigator
A navigator is the person on board a ship or aircraft responsible for its navigation.Grierson, MikeAviation History—Demise of the Flight Navigator FrancoFlyers.org website, October 14, 2008. Retrieved August 31, 2014. The navigator's primary responsibility is to be aware of ship or aircraft position at all times. Responsibilities include planning the journey, advising the ship's captain or aircraft commander of estimated timing to destinations while en route, and ensuring hazards are avoided. The navigator is in charge of maintaining the aircraft or ship's nautical charts, nautical publications, and navigational equipment, and they generally have responsibility for meteorological equipment and communications. With the advent of satellite navigation, the effort required to accurately determine one's position has decreased by orders of magnitude, so the entire field has experienced a revolutionary transition since the 1990s with traditional navigation tasks, like performing c ...

Wolfpack (naval Tactic)
The wolfpack was a convoy attack tactic employed in the Second World War. It was used principally by the U-boats of the during the Battle of the Atlantic, and by the submarines of the United States Navy in the Pacific War. The idea of a co-ordinated submarine attack on convoys had been proposed during the First World War but had no success. In the Atlantic during the Second World War the Germans had considerable successes with their wolfpack attacks but were ultimately defeated by the Allies. In the Pacific the American submarine force was able to devastate Japan’s merchant marine, though this was not solely due to the wolfpack tactic. Wolfpacks fell out of use during the Cold War as the role of the submarine changed and as convoys became rare. World War I During the (German war on trade) Allied ships travelled independently prior to the introduction of the convoy system and were vulnerable to attacks by U-boats operating as 'lone wolves'. By gathering up merchant ships into con ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Shortform Improvisation
Improvisational theatre, often called improvisation or improv, is the form of theatre, often comedy, in which most or all of what is performed is unplanned or unscripted: created spontaneously by the performers. In its purest form, the dialogue, action, story, and characters are created collaboratively by the players as the improvisation unfolds in present time, without use of an already prepared, written script. Improvisational theatre exists in performance as a range of styles of improvisational comedy as well as some non-comedic theatrical performances. It is sometimes used in film and television, both to develop characters and scripts and occasionally as part of the final product. Improvisational techniques are often used extensively in drama programs to train actors for stage, film, and television and can be an important part of the rehearsal process. However, the skills and processes of improvisation are also used outside the context of performing arts. This practice, known ...

Sonar
Sonar (sound navigation and ranging or sonic navigation and ranging) is a technique that uses sound propagation (usually underwater, as in submarine navigation) to navigation, navigate, measure distances (ranging), communicate with or detect objects on or under the surface of the water, such as other vessels. "Sonar" can refer to one of two types of technology: ''passive'' sonar means listening for the sound made by vessels; ''active'' sonar means emitting pulses of sounds and listening for echoes. Sonar may be used as a means of acoustic location and of measurement of the echo characteristics of "targets" in the water. Acoustic location in air was used before the introduction of radar. Sonar may also be used for robot navigation, and SODAR (an upward-looking in-air sonar) is used for atmospheric investigations. The term ''sonar'' is also used for the equipment used to generate and receive the sound. The acoustic frequencies used in sonar systems vary from very low (infrasonic ...

Navy Unit Citation
The Navy Unit Commendation (NUC) is a United States Navy unit award that was established by order of the Secretary of the Navy James Forrestal on 18 December 1944. History Navy and U.S. Marine Corps commands may recommend any Navy or Marine Corps unit for the NUC that has distinguished itself by outstanding heroism in action against the enemy, but not sufficient to justify the award of the Presidential Unit Citation. A unit must have performed service of a character comparable to that which would merit the award of a Silver Star Medal for heroism, or a Legion of Merit for non-combat meritorious service to an individual. Normal performance of duty or participation in many combat missions does not, in itself, justify the award. An award will not be made to a unit for actions of one or more of its component parts, unless the unit performed uniformly as a team, in a manner justifying collective recognition. U.S. Army, U.S. Air Force, and U.S Coast Guard units are also eligible to ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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.
