The US Navy Mk.56 Director was part of a gun-fire control system (GFCS) intended to direct the fire of 3"/50 caliber dual purpose guns but was also coupled to 5"/38 mounts and 40mm Bofors mounts, from the 1950s through the Vietnam War.  It was designed at the Massachusetts Institute of Technology (MIT).  It had an effective range of 30,000 yards and could track bombers at speeds up to 630 miles per hour.  Among the many warships it was fitted to were battleship USS New Jersey BB-62, aircraft carriers USS Yorktown CV-10, USS Intrepid CV-11, USS USS Hornet CV-12, USS Lexington CV-16,  heavy cruiser USS Salem CA-139,  and destroyer USS Turner Joy DD-951, now preserved as museum ships.

From Wikipedia: "The US Navy's Mk.56 Director "...was an intermediate-range, anti-aircraft gun fire-control system. It was designed for use against high-speed subsonic aircraft. It could also be used against surface targets. It was a dual ballistic system. This means that it was capable of simultaneously producing gun orders for two different gun types (e.g.: 5"/38cal and 3"/50cal) against the same target. Its Mk 35 Radar was capable of automatic tracking in bearing, elevation, and range that was as accurate as any optical tracking."
