The principle and features of the laser gyro are summarized in this paper. It is presented that laser gyro has predominant advantages over electric-mechanical and other types of gyros. It meets the demands of strap-down navigation system to inertia measure equipment and has a very strong application in military affairs. The expectation for the application in new generation of air defense missile is given.
