PROBLEM TO BE SOLVED: To provide a fire system capable of improving hitting accuracy of gunshot while considering bending vibration of a gun in a special-purpose vehicle comprising the gun. SOLUTION: Deformation shape by natural vibration of the gun 1 is estimated on the basis of a gun tip vibration signal 32a from a gun tip vibration detecting sensor 2a at a gun natural vibration model portion 11a, a straight signal 33a being effective (H level) when the gun 1 has the straight shape, is produced as a timing signal of a prescribed phase in the natural vibration, a firing signal 34a becomes effective and is output by an AND gate 12a (output means) when a gunner trigger signal 31 by a gunner is effective and the straight signal 33a is effective, and a shell is fired on the basis of the firing signal 34a and shot from the gun 1.
