Claim Text:
1. A method for operating a flying submarine, comprising: providing a rocket propulsion system to cause exhaust propulsive matter from the rocket propulsion system to propel the flying submarine; flooding a ballast tank with water; placing the flying submarine at an appropriate water exiting depth; accelerating the flying submarine to about a maximum forward velocity with a propeller propulsion system; placing the flying submarine at a water exit angle; firing the rocket propulsion system at or just below a water-air interface, thereby providing an exhaust propulsive matter from the rocket propulsion system and propelling the flying submarine to a water exit velocity; unfolding one or more wing structures on the flying submarine to a flying position just at or above the water-air interface; and reversing the propeller propulsion system to operate the propeller in an airborne mode.
