The patent relates to a unique exhaust nozzle for an underwater vehicle which minimizes the generation and radiation of acoustic energy over a wide band of frequencies. The improved exhaust nozzle structure comprises an external annular lip that extends outwardly at a right angle to the longitudinal axis of the vehicle and forms a cavity downstream from the vehicle into which combustion gases of the vehicle are noiselessly discharged.
