KS-19 100-mm Towed AA Gun
Type 59

The Soviet 100mm antiaircraft gun KS-19 was introduced in the late 1940s as the replacement for the wartime 85mm guns. It found use in all of the Warsaw Pact armies, and atthouah it has been largely replaced by surface-to-air guided missiles, the KS-19 is still held in some Warsaw Pact units, and is employed in other countries as well. The KS-19 has a semiautomatic horizontal sliding wedge breechblock, a power rammer, an automatic fuze setter, and is fitted with a long multi-baffle muzzle brake. The antiaircraft fire control system includes a PUAZO-6/19 director and a SON-9 or SON-9A fire control radar. Provision is also made for direct fire against ground targets such as tanks. The ammunition is of the fixed type and is interchangeable to a large extent with that of other 100mm rifled tank and field guns. The KS-19M2 Anti-Aircraft Artillery may also be employed in a ground support role. The Chinese Communists call the gun the type 55.
