ABSTRACT:
A fire control mechanism (4) for an automatic cannon comprises a trigger control member (6), which engages the trigger (3) of the cannon structure (2) and is operable by an actuator (5) to move from an inoperative position against a restoring force to an operative position for operating the trigger. To ensure that the cannon has a capability not only for sustained fire but also for a reliable firing of single shots operative connection between the actuactor (5) and the trigger control member (6) is provided by a clutch (16). An end stop (16) is provided, which is selectively movable to and from an inoperative position and only in said operative position is arranged to disengage said clutch when the actuator has performed the movement which is required to move the trigger control member from its inoperative position to its operative position.
