A means and method for simultaneously reducing drag and noise of a high-sd underwater vehicle is provided. Water is admitted through a water intake scoop in the nose of the vehicle and a polymer powder-gas combination is injected into the water stream in the scoop. The water, polymer and gas are mixed in a mixing chamber into which the scoop empties and are ejected through a circumferential ejector disposed at the minimum pressure point.
