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.
