ABSTRACT:
An unmanned aerial system (UAS) is described that is operable on or in water, in addition to being able to fly in the air. The UAS can float in a body of water, or submerge itself underneath the water, and then later launch from the water without human intervention to perform a flying mission. The UAS can then return back to the water. The UAS incorporates an electric ducted fan acting as the propulsion engine for the UAS in the water as well as in the air.
