The ZSU-23-4MP "Biała" (pl. White, also the name of more than one small Polish river) is a Polish modification of the ZSU-23-4 Shilka self-propelled anti-aircraft gun.
The ZSU-23-4MP Biała was adopted in December of 2005 with a prototype delivered in February 2005.[1] [2] A contract for service on the vehicles between 2021 and 2024 was signed in November 2021.[3]
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.[4] The Grom missiles' maximum range is about 5.5 km.[5]
