Information:  - A fixed-wing aircraft is an aircraft, such as an aeroplane, which is capable of flight using wings that generate lift caused by the vehicle's forward airspeed and the shape of the wings. Fixed-wing aircraft are distinct from rotary-wing aircraft, in which the wings form a rotor mounted on a spinning shaft, and ornithopters, in which the wings flap in similar manner to a bird.  - General Dynamics Corporation is an American aerospace and defense multinational corporation. Formed by mergers and divestitures, it is the world's fifth-largest defense contractor based on 2012 revenues. General Dynamics is headquartered in West Falls Church, Fairfax County, Virginia.  - In military tactics, close air support (CAS) is defined as air action by fixed or rotary-winged aircraft against hostile targets, that are in close proximity to friendly forces, and which requires detailed integration of each air mission with fire and movement of these forces.  - In the broadest definition, a sensor is an object whose purpose is to detect events or changes in its environment and sends the information to the computer which then tells the actuator (output devices) to provide the corresponding output. A sensor is a device that converts real world data (Analog) into data that a computer can understand using ADC (Analog to Digital converter)  - A fire-control system is a number of components working together, usually a gun data computer, a director, and radar, which is designed to assist a weapon system in hitting its target. It performs the same task as a human gunner firing a weapon, but attempts to do so faster and more accurately.  - The Lockheed AC-130 gunship is a heavily armed, long-endurance ground-attack variant of the C-130 Hercules transport fixed-wing aircraft. It carries a wide array of anti-ground oriented weapons that are integrated with sophisticated sensors, navigation, and fire-control systems. Unlike other military fixed-wing aircraft, the AC-130 relies on visual targeting. Because its large profile and low operating altitudes (around 7,000 ft) make it an easy target, it usually flies close air support missions at night.  - Navigation is a field of study that focuses on the process of monitoring and controlling the movement of a craft or vehicle from one place to another. The field of navigation includes four general categories: land navigation, marine navigation, aeronautic navigation, and space navigation.  - The General Dynamics GAU - 12/U Equalizer is a five - barrel 25 mm Gatling - type rotary cannon . The GAU - 12/U is used by the United States , Italy and Spain , which mount the weapon in their fighter jets such as the AV - 8B Harrier II , airborne gunships such as the Lockheed AC - 130 , and land - based fighting vehicles .  - An 'electric motor is an electrical machine that converts electrical energy into mechanical energy. The reverse of this is the conversion of mechanical energy into electrical energy and is done by an electric generator.  - A multinational corporation"" or worldwide Enterprise is a corporate organization that owns or controls production of goods or services in one or more countries other than their home country. It can also be referred as an international corporation, a transnational corporation, or a stateless corporation.  - A gunship is a military aircraft armed with heavy guns, primarily intended for attacking ground targets.  - A rotary cannon, rotary autocannon, or Gatling-type cannon is a rapid-firing weapon that utilizes multiple barrels in a rotating cluster to provide a sustained rate of fire greater than single-barreled machine guns or automatic cannon of equivalent caliber. The loading, firing, and unloading functions are performed simultaneously in different barrels as they rotate, and the rotation also permits the barrels some time to cool. The rotating barrel cluster on most Gatling-type guns is powered by an external force such as an electric motor, although gas-operated versions have also been developed.  - Virginia (, officially the Commonwealth of Virginia) is a state located in the Mid-Atlantic region of the United States, as well as in the historic Southeast. Virginia is nicknamed the "Old Dominion" due to its status as the first colonial possession established in mainland British America, and "Mother of Presidents" because eight U.S. presidents were born there, more than any other state. The geography and climate of the Commonwealth are shaped by the Blue Ridge Mountains and the Chesapeake Bay, which provide habitat for much of its flora and fauna. The capital of the Commonwealth is Richmond; Virginia Beach is the most populous city, and Fairfax County is the most populous political subdivision. The Commonwealth's estimated population is over 8.3 million, which is slightly less than New York City.  - A cannon (plural: "cannon" or "cannons") is any piece of artillery that uses gunpowder or other usually explosive-based propellants to launch a projectile, which may or may not be explosive. Cannon vary in calibre, range, mobility, rate of fire, angle of fire, and firepower; different forms of cannon combine and balance these attributes in varying degrees, depending on their intended use on the battlefield. The word "cannon" is derived from several languages, in which the original definition can usually be translated as "tube", "cane", or "reed". In the modern era, the term "cannon" has fallen into decline, replaced by "guns" or "artillery" if not a more specific term such as "gun", "mortar" or "howitzer", except for in the field of aerial warfare, where it is often used as shorthand for autocannon.    What is the relationship between 'gau-12 equalizer' and 'autocannon'?
