A system for bistatic radar target detection employs an unmanned aerial vehicle (UAV) having a ramjet providing supersonic cruise of the UAV. Deployable antenna arms support a passive radar receiver for bistatic reception of reflected radar pulses. The UAV operates with a UAV flight profile in airspace beyond a radar range limit. The deployable antenna arms have a first retracted position for supersonic cruise and are adapted for deployment to a second extended position acting as an airbrake and providing boresight alignment of the radar receiver. A mothership aircraft has a radar transmitter for transmitting radar pulses and operates with an aircraft flight profile outside the radar range limit. A communications data link operably interconnects the UAV and the tactical mothership aircraft, transmitting data produced by the bistatic reception of reflected radar pulses in the UAV radar antenna to the mothership aircraft.

A projectile with a projectile casing and at least one pyrotechnic charge incorporated in the projectile casing is proposed, wherein the projectile has an open projectile base with a destructible membrane and the pyrotechnic charge burns away at a defined rate during the flight of the projectile, and so the projectile loses mass in such a way that a predetermined effective range is not exceeded. As a result, safety and a nonlethal effect are achieved, in particular outside the effective range.

A canard deployment mechanism includes a canard connected to a shaft that is hingedly attached to a rotatable hub that is moveable between a stowed and deployed position. The mechanism further includes a locking feature on the canard for restraining the canard in the stowed position. In an embodiment the mechanism further includes a pawl rotatably mounted on a drive gear to contact and restrain the canard in the stowed position.

A training ammunition cartridge comprises a projectile and a cartridge case with a pyrotechnic propellant. The projectile has a projectile body with at least one compartment therein forming a void and containing a material that transitions from a solid to a liquid after set-back and after exiting from a barrel of a gun. The void is of such configuration as to cause the liquid material therein to induce forces and moments that, after a period of stable ballistic flight, destabilize the projectile and shorten its flight. Alternatively, the projectile void contains a solid mass that is released to shift its position after set-back and after the projectile exits from the barrel of the gun, wherein the void is of such configuration as to cause the mass, upon shifting, to induce forces and moments that, after a period of stable ballistic flight, destabilize the projectile and shorten its flight.

A smoke munition or smoke grenade which can be fired from a launcher, for example a grenade launcher, and has at least one active charge for producing smoke as a protection for ships. To achieve the effect that the active charge of the smoke grenade can be delivered quickly and safely for the ship's crew and the active compound thereof can be converted completely into smoke even after hitting the water, the invention proposes providing the active charge with a floating aid, which can be deployed before the active charge hits the water and prevents the active charge from sinking and prevents the active compound that produces the smoke from becoming wet.

The inventive subject matter is directed to systems and apparatuses that are designed to work in cooperation with a firearm such that the firearm can fire a less lethal projectile. Systems can include a mounting device that clips onto a firearm, where that mounting device also include mounting posts. The mounting posts protrude from an end of the mounting device, and the mounting posts are designed to couple with mounting holes on an associated slug. Slugs of the inventive subject matter thus feature mounting holes and a center-bored hole that is designed to capture a bullet that is fired from a firearm that the system is coupled to. When a bullet is captured by a slug, an inelastic collision takes place that causes the slug to leave the firearm at around 20% of the bullet's original speed.

Described are spherical projectiles such as used in birdshot, buckshot, or single ball spherical projectiles, including slugs, muzzle loading projectiles, or any close-to-bore diameter projectile, that is auto-segmenting or self-segmenting upon impact with a target. The projectile or shot disclosed herein retains its shape and structure during flight until impact with soft tissue, whereupon its individual sections separate or segment in a controllable manner, each portion of the projectile imparting or depositing a high amount energy to the tissue and target. The auto-segmenting spherical projectiles can be frangible or non-frangible. This disclosure also provides cartridges such as shotshells that are loaded with the projectiles described herein.
