PROBLEM TO BE SOLVED: To maintain the hitting accuracy of a projectile in a high level even under a condition that twisting is generated in a hull by a method wherein a second navigator is installed at the side of a gunshot device to correct an error between a first navigator, installed at the position of center of gravity of a ship, due to the twist of the hull of the ship and operate the firing azimuth as well as the firing angle of the projectile of a gunshot device. SOLUTION: Sub-navigators S, S' are installed at the installing positions of a plurality of gunshot devices 4,4' respectively except a main navigator M, arranged at the vicinity of the position of center of gravity (CG) of a ship 1 and measuring data including the posture of the ship, a navigating azimuth and a navigating speed of the ship. On the other hand, a sight setting unit 2 is provided as the operating means of the firing azimuth as well as the firing angle of the projectile of the gunshot devices 4, 4' in accordance with the measured data of the main navigator M. Further, a gunshot angle correcting unit 3 is provided as an operating device, operating the measuring data of the main navigator M and sub-navigators S, S' by inputting them together and comparing them. In the gunshot angle correcting unit 3, errors due to twisting with respect to the yaw angle, pitch angle and roll angle of the ship are operated to correct the gunshot data based on the errors.
