130-mm (5.12-in) KS-30





One of the standard antiaircraft guns of the Soviet army during World War II was the 85-mm (3,35-in) M1939, replaced in production by the M1944 which had a longer barrel and fired ammunition with higher muzzle velocity for increased range. In 1985 the M1939 and M1944 were still used by almost 20 countries, although in the Warsaw Pact they have been replaced by surface-to-air missiles. After the end of the war the Soviet Union introduced two new towed anti-aircraft guns, the 100-mm (3.94-in) KS-I9 and the 130-mm (5.12-in) KS-30; by 1985 neither of these remained in front-line service with the Soviet Union, although some 20 countries did still use the KS-19 and two or three the much heavier 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.
