The present invention relates to an air independent propulsion system mounted submarine which re-liquefies gasified oxygen to be restored in a liquefied oxygen storage tank or to be provided into the submarine for respiration, so navigates underwater without blowoff to prevent position exposure caused by bubbles and to eliminate a restriction to underwater navigation depth caused by the blowoff and, also, minimizes consumption of the oxygen because of not discharging oxygen gas and drastically extends underwater navigation period to increase operation capability and to reduce operation costs. The air independent propulsion system mounted submarine comprises: the air independent propulsion system; the liquefied oxygen storage tank; and pipes connected to the liquefied oxygen storage tank for discharging the gasified oxygen out of the tank and supplying the liquefied oxygen used in fuel from the tank. The submarine includes a re-liquefying system connected to the liquefied oxygen storage tank, automatically sensing when the pressure within the tank arrives at an estimated value because of the gasified oxygen, concurrently re-liquefying the oxygen gas within the tank and restoring the re-liquefied oxygen or providing the oxygen into the submarine for respiration.
