Fire control apparatus for an antiaircraft weapons system includes manual means for inputting both estimated roll angles and load (g) factors of a maneuvering target aircraft into a fire control computer. In response to other signals received from conventional target tracking and ranging means, the computer first calculates linearly projected future positions of the target aircraft. Corrections, which may be curvilinear, to these projected positions are then calculated from the inputed estimates of aircraft roll angle and load factor. A fire control commander selectively actuates manual controls to cause the fire control computer to combine this correction with the linearly calculated future positions, a substantially more accurate projection of aircraft-gun projectile intercept positions being thereby provided. Control signals corresponding to these new intercept positions are transmitted from the computer to conventional gun laying means to cause the gun to be aimed at the intercept positions. An illustrative example describing addition of the maneuvering corrections to a preexisting fire control system is included.
