Submarine has been in an asymmetric situation of being suppressed in the face of airborne ASW threats. With the improvement of anti-submarine forces in the air，the pressure of submarine air defense has been increasing. Based on effective countermeasures against the threat posed by airborne ASW forces to submarines， the concept of using UUV to launch submarine-to-air missiles is introduced through comparative analysis of the operational performance about submarine and air force platforms， referring to the mature experience of UUV launching torpedoes. The advantages of launching submarine-to-air missiles by UUV are analyzed，and the feasibility analysis of the technical basis and technical difficulties of launching submarine-to-air missiles by UUV are also carried out.
