US12540803 - Tactical high power microwave antenna pedestal

An antenna system comprises a reflector subsystem, a rotatable support structure and a support member. The reflector subsystem receives an input beam and reflects the input beam to produce an output beam steered in elevation by an elevation reflector and in azimuth by an azimuth reflector, towards a target. The rotatable support structure is operably coupled to the azimuth reflector and to the elevation reflector and is configured to rotate them simultaneously. The support member comprises a lengthwise portion coupled to the rotatable support structure and an offset portion coupled to the elevation reflector, the offset portion configured to offset the elevation reflector from the lengthwise portion. The offset portion is configured to enable clearance of the elevation reflector during beam steering of the output beam to extreme ends of a range of motion of the elevation reflector.

US12540804 - Drag reduction fin deployment mechanism

A projectile having a body that includes a nose, a tail opposite to the nose, a chamber defined between the tail and the nose, and a longitudinal axis defined between the nose and the tail. The projectile also includes a payload stored in the chamber of the body, and a propulsion system equipped with the body. The projectile also includes a fin assembly operably engaged with the body between the nose and the tail and is positioned outside of the chamber, wherein a fin of the fin assembly is moveable between a stowed position and a deployed position. In the stowed position, the fin is stowed completely between the nose and the tail. In the deployed position, a portion of the fin extends away from the nose or from the tail.

US12534200 - Suppression for a countermeasure dispensing system

A suppression kit of a countermeasure system and methods of use thereof. The suppression kit includes a breaching expendable that is adapted to be stored inside of a magazine of the countermeasure system. The suppression kit also includes a cover that operably engages with the breaching expendable. The cover is configured to one of suppress electromagnetic signals from penetrating into a dispenser of the countermeasure system, prevent optical or visual view of contents within the countermeasure system, and suppress environmental impacts from entering into the countermeasure system. The breaching expendable is configured to eject the cover from the dispenser prior to ejection of at least one countermeasure expendable of a set of countermeasure expendables.
