Ship gun fire-control systems (GFCS) are analogue fire-control systems that were used aboard naval warships prior to modern electronic computerized systems, to control targeting of guns against surface ships, aircraft, and shore targets, with either optical or radar sighting. Most US ships that are destroyers or larger (but not destroyer ...
A fire-control system (FCS) is a number of components working together, usually a gun data computer, a director and radar, which is designed to assist a ranged weapon system to target, track, and hit a target. It performs the same task as a human gunner firing a weapon, but attempts to do so faster and more accurately.
Design: 15 rpm. Muzzle velocity. 2,600 ft/s (790 m/s) initial. Sights. Optical telescope. The Mark 12 5"/38-caliber gun was a United States dual-purpose naval gun, but also installed in single-purpose mounts on a handful of ships. The 38- caliber barrel was a mid-length compromise between the previous United States standard 5"/51 low-angle gun ...
The Mark 1, and later the Mark 1A, Fire Control Computer was a component of the Mark 37 Gun Fire Control System deployed by the United States Navy during World War II and up to 1991 and possibly later. It was originally developed by Hannibal C. Ford of the Ford Instrument Company [1] and William Newell. It was used on a variety of ships ...
As a result, the Navy developed an improved version MGM for use on the next variant of the Mk 38 MGS. The Mk 38 Mod 2 mounting, also known as the Typhoon Weapon System, [9] features remote control capability, meaning that the operator can safely control the system from within the ship's Combat information center. Two different ammunition types ...
The basis of the system is the 20 mm M61 Vulcan rotary cannon, used by the United States military on various tactical aircraft since 1959, linked to a K u band fire control radar system for acquiring and tracking targets. This proven system was combined with a purpose-made mounting, capable of fast elevation and traverse speeds, to track ...
During development, the Navy Weapons Agency aimed to achieve blind shooting and high-precision interception capabilities for targets that take evasive action within 4,000 yards (3,700 m). Similar to the late model of Mk.51, it is a human-operated GFCS centered on the disturbed-line-of-sight systems Mk.15 (later improved Mk.29) gun sight.
The Type 904 radar tracker was also developed as a derivative of the GWS.22 Seacat air defense missile system. [ 4 ] In addition, the Mk.64 GUNAR, which changed the shooting command radar to the gun side equipment (initially the same AN/SPG-34 as the Mk.63 , later AN/SPG-48 ), was also developed, and this was mainly used by the Royal Canadian ...
