In-flight recovery of an unmanned aerial vehicle (UAV). A towline may be deployed by a host aircraft in-flight in order to recover a target UAV that is also in-flight. A reel on the host aircraft may pay out the towline having a fitting thereon. A catch on the target UAV may engage with the fitting on the towline, and the reel may then retract the towline to thereby pull in the target UAV to the host aircraft. The target UAV may then securely attach with the host aircraft.

A deployable device mountable on a carrier vehicle and configured to collect situation awareness data. The deployable device includes at least one recorder device configured to collect situation awareness data. The deployable device is capable of being ejected from the carrier vehicle and can be configured to operate as a vehicle and/or be towed by the carrier vehicle. The deployable device can continue collection of situation awareness data after being ejected.

Features for in-flight recovery of an unmanned aerial vehicle (UAV). A towline may be deployed by a host aircraft in-flight to recover an in-flight target UAV. The towline or portion thereof may be oriented nearly vertical. The towline may have a fitting thereon. A capture mechanism on the target UAV may have one or more deployable flaps that engage with the near vertical towline and fitting. The flaps may stow to secure the target aircraft to the towline and fitting. The host aircraft may then retract the towline to pull in the target UAV to the host aircraft using a hoist system having a winch. A latching system located in a pylon of the host aircraft, which may be under a wing, may have a towline connector that engages with and secures the target UAV. The host aircraft may have multiple hoist systems for deployment and/or recovery of multiple target UAV's.

The invention provides an airborne passive decoy system for use in the radio waveband, the system comprising a controllable aerial propulsion unit and one or more retroreflectors, wherein the one or more retroreflectors are mounted on, contained within or otherwise borne by the controllable propulsion unit, and wherein the system is configured such that the one or more retroreflectors can be deployed as a decoy at a desired location and/or time. The system is an integral system which does not rely on tethers, cables or suchlike. Related methods and uses are also provided.

A server apparatus includes a communication unit, and a control unit configured to send an instruction for causing flight vehicles to perform a flight operation, to the flight vehicles. The flight operation includes energizing, by a first flight vehicle, a penetration tool toward a target object in a space, holding a first part, penetrated through the target object, and a second part, not penetrated through the target object, of a cord-shaped member attached to the penetration tool, and flying to outside the space, waiting, by a second flight vehicle, outside the space and receiving any one of the first and second parts from the first flight vehicle, and towing, by the first and second flight vehicles, the target object with the cord-shaped member and transporting the target object to outside the space by flying while respectively holding any one and the other of the first and second parts.
