According to one aspect, an aerostat may include an inflatable structure defining a volume, and a payload mechanically coupled to the inflatable structure, the payload including a sensor, an acquisition module, and a controller, the acquisition module operable to generate acquisition energy directable in midair from the payload to an aerial platform flying independently, the controller in electrical communication with the acquisition module and the sensor, the controller configured, based on a signal received from the sensor and associated with flight of the inflatable structure, to operate the acquisition module to direct the acquisition energy to the aerial platform such that independent flight of the aerial platform interruptible by the acquisition energy.

An airframe is provided that can be flown under the control of an operator or an automated sensor and feedback system. The airframe can be any of a variety of known configurations with multiple rotors, fixed or retractable wings, puller or pusher propellers, or jet engines. The airframe includes at least one arm that is used to intercept and disable another airborne vehicle. In some configurations, the arm is fixed and can include fingers at its outer end. In other configurations, the arm is movable from a closed condition to an open condition. A wire or net is connected between the arm and a portion of the airframe so that the wire or net is spread open when the arm is deployed to the open condition. The wire or net are configured to disable or capture a target such as another aerial vehicle.

Methods and apparatus for pointing logic in aircraft are disclosed. A disclosed example apparatus to aim an aiming device carried by an aircraft includes at least one memory, machine readable instructions, and processor circuitry. The processor is to at least one of instantiate or execute the machine readable instructions to determine a position of a target, determine an orientation of the aircraft, determine aiming points based on the orientation and a movement range of the aiming device, and determine a movement of at least one of the aircraft or the aiming device based on the aiming points and the position to orient the aiming device toward the target.

A system and method are provided to defend against intruding aircraft using an intercept aircraft to detonate a radar/kinetic projectile package in proximity to the unwanted aircraft. The projectile device shoots projectiles through the intruding aircraft to disable it. The intercept aircraft includes a radar, a projectile device, and processors operating on radar data to detect the intruding aircraft and predict its path. The intercept aircraft is flown to an intercept point on the predicted path, where the intercept aircraft waits for the intruding aircraft and then detonates an explosive launching the projectiles through the intruding aircraft thereby disabling it and also achieving the self-destruction of the radar/kinetic projectile package and one or more parts (e.g., secret or proprietary parts) of the radar and/or the intercept aircraft.
