130 mm air defense gun KS-30

The Soviet 130mm anti-aircraft gun KS-30 appeared in the early 1950s, closely resembling the German wartime 12.8 cm FlaK 40 antiaircraft gun. The KS-30 was used for the home defense forces of the USSR and some other Warsaw Pact countries. Recognition features are the heavy dual-tire carriage, a firing platform which folds up to a 45 degree angle when the piece is in travel, and the long clean tube without a muzzle brake. The breechblock is of the semi-automatic horizontal sliding wedge type, and the piece is fitted with a power rammer and an automatic fuze setter. Fire control is provided by the PUAZO-30 director and the SON-30 radar. The ammunition is of the fixed-charge, separated type. It is not interchangeable with that of the 130mm field or coastal guns. The KS-30 is now held in war reserve since it was replaced by surface-to-air guided missiles.
