ScanEagle

The ScanEagle is a small, long-endurance, low-altitude unmanned aerial vehicle (UAV) primarily used for reconnaissance, surveillance, and target acquisition. It is launched via a pneumatic catapult and recovered using a 'skyhook' system, which snags a rope hanging from the wing with a vertical wire.

Developed by Insitu in the United States and first flown in 2004, it has seen extensive use by military forces for intelligence gathering.
