US Navy Launches UAV from Submerged Submarine

The U.S. Navy demonstrated the launch of an unmanned aerial system (UAS) from a submerged submarine.
NRL XFC UAS Deployed from the submerged submarine USS Providence, was vertically launched from a 'Sea Robin' launch vehicle (bottom right). The folding wing UAS autonomously deploys its X-wing airfoil and after achieving a marginal altitude, assumes horizontal flight configuration.
The XFC is a fully autonomous, all electric fuel cell powered folding wing UAS with an endurance of greater than six hours.
