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 ...
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.
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.

Cut-away view of a Royal Navy World War II K-class destroyer Director Control Tower (D.C.T.) with Type 285 radar; plotting room shown on lower level This massive concrete casemate housed the underground plotting room for the 12-inch ...
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.
During their long service life, rangekeepers were updated often as technology advanced, and by World War II they were a critical part of an integrated fire control system. The incorporation of radar into the fire control system early in World War II provided ships with the ability to conduct effective gunfire operations at long range in poor ...
