A cryogenic, submersible, synthetic air-breathing system which provides the diver with a proper breathing atmosphere, including provisions for a water-jet propulsion unit to propel the diver to an extended underwater range. The system utilizes liquid oxygen and liquid nitrogen, each stored in respective tanks, whereby the gases pass through a series of heat exchangers, regulators, check valves and a slider valve into which the regulated gases enter a mixing chamber wherein breathable air is generated therein, and then delivered to the diver's face mask-an unmixed portion of the gas being used as the means to power a conventional air motor which, in turn, powers an underwater jet engine.
