One of the many things to note about this gun was its sophisticated
servo drive systems intended for computerised aiming. Instead of the
deffective (in terms of accuracy) limited angular rate deflection
system generally used for for aiming it was to calculate the complete
and total firing solution in cartesian co-ordinates. It wss a one hit
to kill weapon. It was not only for tanks but for naval systems as
well as for ground based FLAK.
Post war the Soviet 57 mm AZP S-60 evolved from this weapon.
