Northrop Grumman has started shipping the Mk44 Bushmaster II to Poland for integration on its Borsuk infantry fighting vehicle (IFV). The 30mm chain-driven autocannon is already in service across NATO, recognized for dependable performance and flexibility across land and naval systems.
Weighing 160 kilograms, the Bushmaster II measures 3,405 millimeters in overall length and 2,410 millimeters at the barrel. It supports dual ammunition feeds, providing crews with greater adaptability in combat scenarios. The weapon’s cyclic rate of 100–200 rounds per minute allows effective fire at distances of 3,000 meters on ground platforms and over 5,000 meters when installed on maritime vessels.
The Borsuk IFV program, launched in 2017, represents Poland’s first fully indigenous tracked vehicle, intended to succeed Soviet-era BMP-1s. At eight meters long and 28 tonnes in weight, it combines strong protection with mobility, carrying a three-person crew and six infantry. Powered by a 720-horsepower MTU diesel engine and Allison transmission, the vehicle reaches top speeds of 65 kilometers per hour and offers a range of 550 kilometers.
Under a $1.7 billion contract signed in 2024, Poland will receive 111 Borsuks by 2029, with plans to expand the fleet to nearly 1,400 vehicles. The procurement will include over 1,000 standard IFVs and about 400 specialized variants, reinforcing Poland’s defense modernization strategy and NATO interoperability.
