krab (estimated)

The AHS Krab is a Polish 155 mm NATO-compatible self-propelled howitzer. It integrates a South Korean K9 Thunder chassis with a British AS-90M Braveheart turret and a Polish fire control system.

Conceived in the late 1990s under Poland's "Regina" modernization program, the Krab was developed to replace obsolete Soviet-era artillery with a modern, NATO-standard system. After early domestic chassis designs suffered from structural defects, Poland integrated the South Korean K9 platform, leading to the finalized system officially entering service with the Polish Land Forces in 2015. The howitzer saw its first major combat deployment during the 2022 Russian invasion of Ukraine, where donated Polish units earned high praise for their mobility, range, and survivability in intense counter-battery duels. Today, the Krab remains a cornerstone of Polish armored brigades and has secured its legacy as one of the most combat-proven 155mm artillery systems of the 21st century.
