A means and method of controlling the muzzle velocity of a gun launched projectile to ensure that the muzzle velocities of several rounds of the same type tend towards the same value or that of an individual round approaches some nominal value. A sensor means measures a parameter related to the muzzle velocity of a projectile and a control means instructs an electrothermal energy unit to discharge a fixed amount of energy into the gun barrel after a certain time delay, the time delay being derived from the measured parameter and being such to ensure that discharge causes the projectile to achieve a controlled muzzle velocity.

[ We claim:] [1.] A means for controlling the muzzle velocity of a gun launched projectile comprising;a sensor means capable of measuring a parameter related to the muzzle velocity of a projectile,a control means andan electrothermal energy unit capable of discharging a fixed amount of electrothermal energy into a gun barrel upon receipt of a trigger signal from said control means,wherein said control means introduces a delay into the transmission of the trigger signal to said electrothermal energy unit, said delay being dependent upon the valve of the measured parameter such that discharge of said fixed amount of electrothermal energy causes the projectile to achieve a controlled muzzle velocity.
