Poland contracted for 672 K9A1 Thunder self-propelled howitzers from Hanwha Defense in August 2022 — the largest-ever K9 export order. Deliveries include South Korean-built systems and a production line at HSW Stalowa Wola for the K9PL (Poland) variant. The K9A1 is the upgraded variant featuring an auto-layer, improved fire control, and reliability improvements over baseline K9. Rate of fire is 6 rounds/minute sustained (burst: 3 rounds in 15 seconds). Range: 40+ km standard, 50+ km with extended-range munitions. The 672-unit fleet will be Poland's primary artillery backbone, alongside the Krab and HIMARS systems.

- Largest South Korean export success — Poland, India, Norway, Egypt, Australia
- 52-caliber barrel extends range 25% vs M109 Paladin 39-cal
- Autoloader reduces crew fatigue and maintains high rate of fire
- Proven in combat (Indian K9 Vajra in Galwan sector)
- Established global support network across multiple operator nations
- Tracked platform requires heavy transport for strategic redeployment
- Semi-autoloader is slower than fully automatic systems
- Full crew of 5 is larger than some competitors
- Advanced guided munitions compatibility requires expensive upgrades
- High unit cost vs. wheeled SPH alternatives (Caesar, Archer)

SIGN INThe vertical launch capacity here provides mission flexibility that single-role warships simply cannot match.
Mobility cross-country is more operationally significant than top speed on paved surfaces. This platform understands that.
