The current management board of Mesko has significantly accelerated the implementation of two strategic investment projects – Project 400 and Project 44.7 – which are of fundamental importance for the company’s development, Poland’s independence from foreign suppliers, and the strengthening of national defense capabilities. Thanks to these investments, by 2026 Mesko will achieve significantly greater production capacity in the field of ammunition and missiles, as well as acquire key competencies in the production of multi-base propellants.

“These projects represent a true breakthrough not only for our company but for the entire national defense industry. We have significantly accelerated the implementation of delayed investments of strategic importance – both in terms of expanding production capacity and acquiring competencies that Poland has not previously possessed. We are nearing completion of Project 400, while simultaneously and consistently advancing Project 44.7, which will significantly reduce the domestic ammunition industry’s dependence on foreign propellant supplies,” emphasized Renata Gruszczyńska, President of the Management Board of Mesko.
“In recent months, after years of stagnation, we’ve seen a major breakthrough, resulting in significant progress in the pace of both projects. We are finalizing investments that will strengthen Mesko and enhance national security. I can say with full confidence that we are about to open a new chapter in the history of Mesko and the entire defense industry in Poland,” added Renata Gruszczyńska.
Project 400 has been under implementation since 2019. Its budget amounts to 466.7 million PLN, including 400 million PLN from the Reprivatization Fund and a 66.7 million PLN contribution from Mesko. The investment covers over 1,000 machines and devices as well as more than 20 facilities located in Skarżysko-Kamienna and Pionki. The main objective of the project is to increase Mesko’s production capacity in the areas of small-, medium-, and large-caliber ammunition and missiles, as well as to acquire competencies in the production of multi-base propellants and combustible cartridge cases.
In Skarżysko-Kamienna, acceptance procedures are currently underway for the last two newly built production facilities – the missile hall and the ammunition hall. According to the updated schedule, production in these buildings will begin in 2025. The remaining facilities under the project were previously commissioned.
In Pionki, several buildings designated for large-caliber ammunition production have been completed. In March 2025, acceptance of the technological line in one of the halls was finalized, while acceptance procedures for the second facility are planned for completion by the end of the second quarter of 2025. Full completion of all construction work under Project 400 is scheduled for December 2025. Once the final facilities are equipped with machinery, the company will reach its target production capacity.
The production of small-caliber ammunition is expected to increase by 500% compared to current levels – reaching 250 million rounds annually, which translates to 1 million rounds per working day.
The simultaneously implemented Project 44.7 focuses on developing the capability to produce modified propellants needed for the manufacturing of various calibers of ammunition. Currently, Mesko has the competence to produce single-base and partially modified single-base propellants. The first results of the project are already evident in the use of modified propellant for fulfilling a contract with the Ministry of National Defence for 12.7 x 99 mm NATO ammunition.
The key milestone, however, will be the planned launch of multi-base propellant production in 2026.
“The completion of the investment and commissioning of modern production lines in 2025 and 2026 will allow Mesko to strengthen its position as one of the most advanced ammunition and missile manufacturing plants in Europe. On one hand, the company will increase the production volume of 155 mm ammunition and other key munitions; on the other, it will become an independent producer of energetic components – something previously entirely out of reach for the Polish defense industry. This will free Poland from dependence on imported raw materials necessary for ammunition production, ensuring secure and stable supply for the Polish Armed Forces,” emphasized Renata Gruszczyńska, President of the Management Board of Mesko (The first thousands of 155 mm rounds have already rolled off Mesko’s production lines – target: 150,000 rounds per year).
