Development of 155 mm Artillery Ammunition by WB Group
Overview of the Initiative
Poland’s WB Group has advanced its defense capabilities by initiating the development of 155 mm artillery ammunition. The announcement was made on December 11, with significant implications for both national and regional military preparedness.
Project Status and Production Timeline
According to CEO Piotr Wojciechowski, the initial trials of the projectiles have yielded promising results. The company anticipates readiness for serial production by December 2026. Key milestones include:
- Testing Phase: Inert rounds are currently undergoing evaluations.
- Production Facilities: An ammunition assembly center has been established in western Poland, designed to accommodate large volumes of explosives along with the manufacture and storage of finished artillery rounds.
Types of Ammunition
WB Group will produce two primary categories of artillery shells:
- High-Explosive Hollow Base (HE-HB)
- High-Explosive Base Bleed (HE-BB)
Supply Chain and Component Sourcing
Wojciechowski noted that the fuzes for these munitions are being sourced from an external supplier. The company is also in negotiations with two European suppliers regarding the propellant charges. Additionally, developments surrounding gas generators have progressed, with successful bench testing completed.
Certification and Production Goals
The certification process is projected to conclude by September 2026. The following production objectives are set:
- Initial Deliveries: An estimated 5,000 to 10,000 rounds by the end of 2026.
- Full-Scale Production: Aiming for annual output between 50,000 and 100,000 rounds starting in 2027.
The certification endeavor is being pursued through parallel tracks in Poland and international markets, ensuring that WB Group’s ammunition will be available for global distribution.
Strategic Implications
The establishment of WB Group’s ammunition production capability not only enhances Poland’s military readiness but also positions the country as a potential supplier within the regional defense industry. This initiative underscores the broader trend among Eastern European nations to bolster their military manufacturing capacities in response to evolving security challenges.
This initiative represents a crucial development in Poland’s defense infrastructure, reflecting both a commitment to self-reliance in military capabilities and a strategic approach to enhancing regional security partnerships.
