1. An aerial vehicle system, the system comprising: an unmanned aerial vehicle and a portable launcher;wherein said unmanned aerial vehicle comprises: a body defining a longitudinal axis,a first wing extending laterally in a first direction from the body,a second wing extending laterally in a second direction from the body, the second direction being opposite the first direction,a first flight control surface supported by the body and configured to control pitch of the vehicle,a second flight control surface supported by the body and configured to control yaw of the vehicle,a controller including a flight control system operably coupled to the first flight control surface and the second flight control surface,a propulsion device operably coupled to the body;an acquisition sensor including an optical receiver for detecting a target, the optical receiver including a video processor and a lens to direct light to the video processor, wherein the video processor including a focal plane array having a collector grid to receive the light from the lens;a navigation system including an inertial measurement system for detecting pitch, roll, and yaw of the aerial vehicle, and an inertial navigational system to determine position, orientation, and velocity of the aerial vehicle;a trigger sensor configured to generate a signal in response to a predefined stimulus; anda responder in electrical communication with the controller and configured to be activated in response to the signal from the trigger sensor;wherein said portable launcher including a support to hold the body in a stored mode of operation, and a deployment mechanism to propel the body upwardly into the air in a launch mode of operation;wherein the deployment mechanism comprises a catapult operably coupled to the support, the body supporting a hook configured to engage the catapult in the stored mode;wherein the controller is in communication with the acquisition sensor, and the controller adjusts the flight control surfaces to reposition the target within the center of the collector grid of the video processor;wherein the trigger sensor includes a plurality of light emitting diodes and a plurality of receivers configured to receive light from the plurality of light emitting diodes and in electrical communication with the controller;wherein said acquisition sensor is mounted within a repositionable receiver assembly adapted to direct said optical receiver downwardly from the body and configured to commence target identification processing when the navigation system determines the aerial vehicle has reached an area of interest and enters a search mode. 2. The system of claim 1, further comprising: a responder in electrical communication with the controller; anda safe and arm device configured to arm the responder at a predetermined distance from launch. 3. The system of claim 2, wherein the safe and arm device includes a fiber optics cable releasably coupled to the controller in an unarmed condition. 4. The system of claim 1, wherein the controller operates in said search mode of operation when the acquisition sensor actively seeks to identify the target and causes the flight control surfaces to direct the aerial vehicle in a downward spiral flight path, a terminal mode of operation when the acquisition sensor detects a predefined target and causes the flight control surfaces to direct the body toward the target, and an activation mode of operation when the trigger sensor detects the predefined stimulus. 5. The system of claim 1, wherein the responder comprises an explosive detonated by the controller in response to a signal from the trigger sensor. 6. The system of claim 1, wherein said plurality of light emitting diodes are positioned on different positions of the unmanned aerial vehicle including a front, top, and side sections of said unmanned aerial vehicle. 7. The system of claim 1, wherein said acquisition sensor is adapted to compare a collected image to a stored image of the target. 8. The system as of claim 7, wherein said acquisitions sensor further comprises a filter processing section with masking conditions adapted to determine if said collected image has a hot spot in said area of interest below the unmanned aerial vehicle, wherein if said acquisition sensor determines that a collected image and the stored image are substantially identical, then the controller acquires the target and activates additional filter processing sections to determine if said target is a valid target. 9. The system as in claim 8, wherein said additional filter processing comprises attempts to match parametric goals and engage in target recognition by comparing temperature indications to pixels in a mask, wherein when said hot spot is found, then a next filter is applied by the acquisition sensor as a comparison with at least one or more stored mask forms and pattern recognition library. 10. The system as in claim 9, wherein the controller operates in said search mode of operation when the acquisition sensor actively seeks to identify the target and causes the flight control surfaces to direct the aerial vehicle in a downward spiral flight path, said controller operates in a terminal mode of operation when the acquisition sensor detects a predefined target upon a match of at least one said stored said mask forms or at least one pattern recognition data in said pattern recognition library and causes the flight control surfaces to direct the body toward the target, and said controller operates in an activation mode of operation when the trigger sensor detects the predefined stimulus. 11. The system as in claim 1, where said catapult is adapted to engage with said hook such that said catapult applies force to said hook to launch said body away from said deployment mechanism.
