An air-launched aircraft includes deployable wings, elevons, and vertical fins that deploy from a fuselage during flight. The aircraft may include a control system for operating the elevons, a communication system, and batteries for powering the systems. In addition, the aircraft may include a payload module that mates with an interface in the fuselage. The payload module may include any of a variety of payloads, including cameras, sensors, and/or radar emitters. The aircraft may be powered or unpowered, and may be very small, for example, less than on the order of 10 kg (22 pounds). The aircraft may be employed at a low cost for any of a wide variety of functions, such as surveillance, or as a decoy. The deployable surfaces of the aircraft may be configured to deploy in a pre-determined order, allowing the aircraft automatically to enter controlled flight after being launched in a tumbling mode.

The aircraft of claim 1, further comprising a payload module coupled to the fuselage. 14. The aircraft of claim 13, wherein the fuselage includes a payload interface for coupling the payload to the fuselage; and wherein the payload interface includes a data interface and an electrical interface. 15. The aircraft of claim 13, wherein the payload module includes a radar emitter. 16. The aircraft of claim 13, wherein the payload module includes a sensor. 17. The aircraft of claim 13, wherein the payload module includes a camera. 18. The aircraft of claim 1, wherein the fuselage includes: a power supply; a control system that is operatively coupled to the power supply and the control surfaces; and a communication system that is coupled to the power supply. 19. The aircraft of claim 18, wherein the power supply includes at least one battery. 20. The aircraft of claim 1, wherein the elevons are single-piece planar control surfaces that tilt in their entirety relative to the fuselage. 21. The aircraft of claim 20, further comprising elevon actuators within the fuselage that are operatively coupled to the elevons to tilt the elevons. 22. The aircraft of claim 21, wherein the elevon actuators are mechanically coupled to elevon shafts of the elevons, to rotate the elevons about the elevon shafts. 23. The aircraft of claim 22, wherein the elevon actuators include actuator shafts that are coupled to the elevon shafts by pins. 24. The aircraft of claim 23, further comprising an elevon deployment system for deploying the elevons from the slots; wherein the elevon deployment system includes springs for deploying the elevons by rotating the elevon shafts relative to the actuator shafts, about the pins.
