AMMUNITION FUZES (blasting cartridge initiators F42B3/10; chemical aspects C06C); ARMING OR SAFETY MEANS THEREFOR (filling fuzes F42B33/02; fitting or extracting primers in or from fuzes F42B33/04; containers for fuzes F42B39/30)

Description

F42C covers fuzing systems and mechanisms for ammunition, including devices that initiate detonation or projectile firing. This class encompasses fuze designs, arming mechanisms, safety devices, and related components that control when and how ammunition is activated. Typical applications include artillery shells, bombs, mines, torpedoes, and other ordnance where controlled initiation timing or safety interlocks are critical. Related fuze-specific designs such as impact fuzes, time fuzes, proximity fuzes, and electronic firing mechanisms fall within this scope.
