Abstract: Disclosed herein is an expendable flight kit attachable to a sonobuoy for making use of said sonobuoy as a central structural load-bearing component of a flying assembly, the kit comprising rigid aerodynamic surfaces to provide lift and stability; a propulsion system; a plurality of control surfaces; a plurality of control surface actuators operable for moving the control surfaces in response to control signals; a flight control system, the fight control system including a GPS receiver and attitude and airspeed sensors, the flight control system being operable for receiving mission parameters including sonobuoy deployment co-ordinates, the flight control system being operable for autonomously navigating and steering the vehicle in flight using information from the GPS receiver and the attitude and airspeed sensors, the fight control system being operable for sending control signals to control the control surface actuators, the flying assembly operable to be launched from a ship; the flight control system oper

Abstract: A flight kit that can be retrofitted to existing navy sonobuoys. The preferred embodiment gives sonobuoys the capability of self-deployment, allowing them to be sent to a location remotely without the use of manned aircraft or recoverable unmanned air vehicles. This capability is advantageous in instances where it is desired to place a sonobuoy in an area hostile or hazardous to manned aircraft. The preferred embodiment is an attachment of a GPS navigation and control system, wings, control surfaces, and a propulsion system, onto a naval size-A sonobuoy, using the sonobuoy as the central structural load-bearing component of the assembly. The invention navigates from a launch point on a ship to a designated position, where the sonobuoy separates from the invention, using the wings' aerodynamic forces to mechanically assist in separating the sonobuoy from the flight kit. The sonobuoy and the flight kit enter the water separately to ensure no interference with the sonobuoy.
