ZSU-23-4MP Biała
The ZSU-23-4MP "Biała" is a Polish modification of the ZSU-23-4 Shilka self-propelled anti-aircraft gun. The ZSU-23-4MP "Biała" includes a new digital optical targeting system and 4 Grom surface-to-air missile launcher. The AZP-23 autocannons are equipped with modern ammunition and have an increased effective anti-aircraft range to about 3.5 km, 0.5–1 km more than the original ZSU-23-4. The Grom missiles' maximum range is about 5.5 km.
Around 70 ZSU-23-4MP "Biała" self-propelled anti-aircraft guns are to be produced for the Polish army, as a cheaper alternative to the modern Polish 35 mm PZA Loara self-propelled anti-aircraft gun.
