A Mk V Fuze setting tray with a 4 in (102 mm) anti-aircraft (A/A) round. The Fuze setting tray received its fuze timing information, via electrical signals from the FKC, on a receiver dial. The operator then matched the settings on the receiver dial with the indicator dial on the tray, which then adjusted the clockwork mechanism in the A/A warhead to the calculated time of flight to the target.
The Fuze Keeping Clock (FKC) was a simplified version of the Royal Navy's High Angle Control System analogue fire control computer.[1] It first appeared as the FKC MkII in destroyers of the 1938 Tribal class,[2] while later variants were used on sloops, frigates, destroyers, aircraft carriers and several cruisers.[3] The FKC MkII was a non-tachymetric anti-aircraft fire control computer. It could accurately engage targets with a maximum speed of 250 knots (460 km/h; 290 mph).[2]
