In 1944, the US Army contracted [7] for an electronic "computer with guns, a tracking radar, plotting boards and communications equipment" (M33C & M33D models used different subassemblies for 90 & 120 mm gun/ammunition ballistics.) [3] The "trial model predecessor" (T-33) was used as late as 1953, [8] and the production M33 (each $383,000 in 1954 dollars) [9] had been deployed in 1950. [10]
Mark 1A Computer. The Mark 1A Fire Control Computer was an electro-mechanical analog ballistic computer. Originally designated the Mark 1, design modifications were extensive enough to change it to "Mark 1A". The Mark 1A appeared post World War II and may have incorporated technology developed for the Bell Labs Mark 8, Fire Control Computer. [38]
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.
World War II–era Mark 37 Director for 5 in/38 caliber dual purpose guns above bridge of destroyer USS Cassin Young, backfitted with postwar AN/SPG-25 radar antenna. For warships of the 20th century, the director is part of the fire control system; it passes information to the computer that calculates range and elevation for the guns.

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.
M10: A ballistics computer, part of the M38 fire control system, for Skysweeper anti-aircraft guns. M13: A ballistics computer for M48 tanks. M14: A ballistics computer for M103 heavy tanks. M15: A part of the M35 field artillery fire-control system, which included the M1 gunnery officer console and M27 power supply.
The speed of the tracking target is obtained by the gyroscope of the directional board and the tachometer generator of the distance tracking servo system. Ballistic calculation was performed by the Mk.42 ballistic computer housed in the ship, and it was possible to aim two types of guns at the same target by adding a ballistic calculation ...
