SARPAL AMV (Search and Rescue Portable, Air-Launchable Autonomous Marine Vehicle)

SARPAL is an air-droppable, unmanned surface vehicle developed for the Canadian Department of National Defense (DND) by International Submarine Engineering to rescue victims at sea.  Upon deployment from a C-130 aircraft, parachutes deploy, and the vessel's main tube inflates.  The weather hood erects upon landing in the water and the diesel engine is started. TV cameras to help locate and monitor victims are fitted fore, aft, and inside the boat.  SARPAL can be controlled remotely from an air, land, or sea platform. At least two AMVs have been built.
