An elongate cylindrical projectile including processing circuitry, a head assembly, a tail section assembly, a mid body section positioned between the head assembly and tail assembly, and a wing assembly, the wing assembly including a deployable wing which is stored in a closed position entirely within the mid body section and is deployed, using an actuator, to outside the mid body section in an open position in response to a command from the processing circuitry.

An extended range, enhanced lethality 40 mm ammunition round. The round features controlled guidance and camera front end, which can be fired as fin stabilized with no appreciable spin, from an M320 grenade launcher. The round has a launching sleeve with an oversized propellant cup, to essentially double or triple conventional range, with sharp accuracy provided by the guidance system.

A device for blocking a fin of a projectile, the fin including a fin base pivoting about a pivot pin secured to the body of the projectile between a withdrawn fin position and a deployed fin position, wherein the device includes at least one recess housing at least one shape of revolution pushed by a resilient means between a first surface borne by the fin and a second surface borne by the body of the projectile, at least one of the two surfaces forming a ramp that converges toward the other surface to tend to cause jamming of the shape of revolution between the two surfaces.

A guided projectile that includes a warhead case, a cartridge case coupled to the warhead case, and a tail kit assembly positioned within the cartridge case. The tail kit assembly includes a hollow casing including a plurality of fin slots defined therein, a control fin selectively extendable from within the hollow casing through each fin slot of the plurality of fin slots, and a fin slot cover positioned within each fin slot with a minimum clearance fit such that the control fin is retained within the hollow casing. The fin slot cover is releasable from within each fin slot such that the control fin is deployable therethrough.

A projectile that includes strakes mounted about the perimeter of the midsection of the projectile and a pusher plate assembly mounted about the aft of the projectile so that a sub-caliber projectile may be fired from a larger caliber gun. The pusher plate assembly forms a seal with the bore at the aft end of the projectile. The strakes maintain the center line position of the projectile within the bore. The pusher plate assembly further designed to fragment upon exiting the bore while the strakes remain with the projectile to enhance aerodynamic qualities of the projectile in flight.

The invention relates to programmable practice ammunition. For this purpose, a projectile head of a practice projectile of the practice ammunition has at least one electronic system in the form of an electronic fuze replacement system and a signal transmitter. Optionally, an explosive charge can be introduced into the projectile head. The explosive charge is preferably a pyrotechnic. A light signal, an infrared signal, a radio signal, or another suitable electronic or optical signal, even a color signal, can be output and transmitted via the signal transmitter. Optionally, the explosive charge can be triggered and deployed via the signal transmitter. The projectile is provided with radial openings for this purpose. The invention additionally relates to a training system for a realistic practice using an explosive representation at the target or in the target area.

A projectile and method of deploying a projectile includes a wing deployment system for deploying a wing of a projectile. The wing deployment system includes a stored energy release mechanism that is activated to generate an initial range of motion of the wing and a panel arranged on the wing and configured to cause an angular acceleration of the wing during the initial range of motion of the wing.
