The present disclosure provides a system for securing wireless data communication. The system includes a launcher and a projectile. The launcher has a random number generator, a launcher memory, a launcher encryption/decryption module, and a launcher transceiver. The projectile has a projectile memory, a projectile encryption/decryption module, and a projectile transceiver. Both the launcher encryption/decryption module and the projectile encryption/decryption module are configured to use the one-time pad to encrypt and to decrypt data. The system is configured to establish a temporary datalink at a point in time in which the projectile and the launcher are substantially collocated so that the one-time pad can be transmitted from random number generator located in the launcher to the projectile memory using the temporary datalink.

A heat dissipation structure is disclosed that is especially well-suited for use on aerodynamic systems. The heat dissipation structure is formed within a metallic body that surrounds the heat-generating electronics. The heat dissipation structure is designed to both dissipate the generated heat and also to isolate RF cross-talk between the one or more transmitters and receivers. The heat dissipation structure includes a plurality of ring structures that extend around at least a portion of a body that houses the one or more heat-generating electrical components. The plurality of ring structures may be recessed into the body, and a first spacing between a first adjacent pair of ring structures of the plurality of ring structures is different from a second spacing between a second adjacent pair of ring structures of the plurality of ring structures.

A modular launching device for launching of projectiles with a propellant charge is provided where the projectile is arranged such that a detonator is arranged at a projectile body in the launching device and assembled together with at least one propellant charge in the launching device. A method of assembling projectiles in a launching device by using modules is also provided.

An apparatus includes at least one memory configured to store map data. The apparatus also includes at least one processor configured to segment one or more objects from one or more environment surfaces in the map data. The at least one processor is also configured to determine an offset based on a projectile drift. The at least one processor is further configured to generate a safety bounding box around each of the one or more objects using the offset.

A hyper-velocity impact sensor including an optical fiber probe that transmits an optical pulse generated during impact with an object, a spectroscopic analyzer that receives the optical pulse and produces spectral information about the optical pulse, a connecting optical fiber configured to convey the optical pulse between the optical fiber probe and the spectroscopic analyzer, and at least one processor coupled to the spectroscopic analyzer and configured to receive and analyze the spectral information to determine at least one chemical element or compound contained in the object.

A system for bistatic radar target detection employs an unmanned aerial vehicle (UAV) having a radar antenna for bistatic reception of reflected radar pulses. The UAV operates with a flight profile in contested airspace. A tactical fighter aircraft having a radar transmitter for transmitting radar pulses operates with a flight profile in uncontested airspace. A communications data link operably interconnects the UAV and the tactical fighter aircraft, the communications data link transmitting data produced by the bistatic reception of reflected radar pulses in the UAV radar antenna to the fighter aircraft.

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.
