Fuze Keeping Clock
The Fuze Keeping Clock (FKC) was a simplified version of the British Royal Navy High Angle Control System (HACS), an analog computing weapons control system. It first appeared as the FKC MkII in Second Tribal class destroyers of 1936, while later variants were used on sloops , frigates , destroyers , aircraft carriers, and several cruisers. The FKC-MkII was a non-total station anti-aircraft weapon control system for combating air strikes. It could capture targets at a maximum speed of 250 knots (460 km / h).
functionality
The FKC calculated the altitude , range , direction and speed of an enemy aircraft using the Rangefinder Director and the vertical reference information from a Gyro Level Corrector . In order to hit the target without deviation, this data was used to determine the exact alignment of the anti-aircraft guns and the exact ignition time of the projectiles in the vicinity of the enemy aircraft.
