The Tizard Mission to the United States provided the USN with crucial data on UK and Royal Navy radar technology and fire-control radar systems. In September 1941, the first rectangular Mark 4 Fire-control radar antenna was mounted on a Mark 37 Director, [39] and became a common feature on USN Directors by mid 1942. Soon aircraft flew faster ...
The fire-control radar must be directed to the general location of the target due to the radar's narrow beam width. This phase is also called "lighting up". [3] It ends when lock-on is acquired. Acquisition phase The fire-control radar switches to the acquisition phase of operation once the radar is in the general vicinity of the target.
Mark 1A Computer Mk 37 Director above the bridge of destroyer USS Cassin Young with AN/SPG-25 radar antenna. 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.
The Mark 92 Fire Control System is a US-built medium-range anti-aircraft missile and gun fire control system. It was developed for the FFG-7 Oliver Hazard Perry class guided missile frigates. The system is a licensed USN version of the Thales Nederland WM-25 fire control system. The Mark 92 fire control system was approved for service use in 1975.
The 5-inch guns were guided by a Mark 37 Gun Fire Control System with a Mark 25 fire control radar linked by a Mark 1A Fire Control Computer stabilized by a Mark 6 8,500 rpm gyro. This fire control system provided effective long-range anti-aircraft (AA) or anti-surface fire.
The Mark 8 (FH) fire-control radar, was based on a new type of antenna developed by George Mueller. This was an end-fired array of 42 pipe-like waveguides that allowed electronic steering of the beam; for this the BTL developed the Mark 4 Fire Control Computer. The Mark 22 was a "nodding" system used for target height-finding with fire-control ...
The primary means of controlling the main armament are two Mark 38 directors for the Mark 38 fire-control system mounted at the tops of the fore and aft fire-control towers in the superstructure. These directors were equipped with 25-foot-6-inch-long (7.8 m) rangefinders , although their primary sensor was the Mark 8 fire-control radar mounted ...
A German anti-aircraft 88 mm Flak gun with its fire-control computer from World War II. Displayed in the Canadian War Museum.. 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.
