Borsuk

Poland's new amphibious infantry fighting vehicle — the Borsuk ("Badger") is the long-awaited replacement for the thousands of Soviet-era BMP-1s Poland inherited from the Warsaw Pact era. A modern, swimming, tracked fighting vehicle with an unmanned turret carrying a 30mm cannon and Spike anti-tank missiles, it is one of the flagships of Poland's enormous post-2022 military build-up — and, after years of development, it finally began entering Polish Army service in 2025.

Overview

The Borsuk (Polish for "badger") is an amphibious tracked infantry fighting vehicle developed by Huta Stalowa Wola (HSW) for the Polish Army. Its purpose is generational replacement: Poland still fielded large numbers of the obsolete Soviet BWP-1 (a Polish BMP-1), and the Borsuk is the modern, indigenous IFV meant to supersede them. It pairs a new amphibious tracked hull with the Polish ZSSW-30 remote (unmanned) turret — a 30mm Bushmaster II cannon, a 7.62mm coaxial machine gun, and a dual launcher for Spike-LR anti-tank guided missiles — giving Polish mechanized infantry a swimming, well-armed, modern fighting vehicle for the first time. With a framework order on the scale of well over a thousand vehicles, the Borsuk is a centrepiece of Poland's drive to become the most heavily-armed land force in Europe.

Development

The Borsuk was developed by HSW as Poland's "New Floating Infantry Fighting Vehicle" (NBPWP) program to replace the BWP-1, with prototypes demonstrated from around 2017 onward, per Wikipedia and Army Recognition. On 28 February 2023 Poland's Armaments Agency signed a framework agreement with HSW for delivery of the vehicle (reported at well over a thousand units, a figure consistent with Poland's massive rearmament), and the first vehicles were handed over in December 2025, marking the type's entry into service. The Borsuk's ZSSW-30 unmanned turret is a separate but linked Polish development (also fitted to the wheeled Rosomak), giving Poland a common modern turret across tracked and wheeled fleets. The program is one of several big Polish land procurements (alongside Korean K2 tanks and K9 howitzers, the Krab, and US Abrams and HIMARS) that have reshaped the Polish Army since 2022.
