Naval Research Lab Sender

The Sender (Self-Navigating Drone, Expendable/Recoverable) multi-purpose mini-UAV was developed and tested by the Naval Research Laboratory between 1992 and 1997.

Sender could be launched either by a bungee cord, a catapult, a booster rocket or from an aircraft. Powered by an electric motor, it could cruise at 93 km/h (57 mph) for up to two hours and was recovered by a belly skid landing. Operational range was 93 km (50 nm) and normal operational altitude was about 300 m (1000 ft). The UAV was equipped with a GPS navigation system, and waypoints could be preprogrammed and updated in flight using a hand-held computer. The UAV could be quickly dismantled and reassembled, and the whole system was completely man-portable.
