Russia has increased its annual artillery ammunition production by a factor of more than seventeen since 2021, reaching 7 million rounds per year - and according to Estonian intelligence, the surplus is being accumulated for a war beyond Ukraine. This assessment, featured in a comprehensive PISM report on Baltic Sea security published in March 2026, signals that Moscow's defense-industrial mobilization serves strategic objectives that extend well past the current battlefield.
As "Hvylya" reports, citing the Polish Institute of International Affairs, the production surge from a pre-invasion baseline of 400,000 rounds annually has allowed Russia to reduce its dependence on external suppliers. Since 2023, Moscow obtained an estimated 5 to 7 million ammunition units from North Korea and Iran. The new domestic output means Russia can sustain its current consumption rate in Ukraine - estimated at 10,000 to 15,000 rounds per day - while simultaneously building reserves.
The Estonian Foreign Intelligence Service's 2026 assessment, referenced in the PISM report, states explicitly that "the rebuilding of Russian artillery stocks is not limited to the needs of the war in Ukraine, but is being accumulated for the needs of another war." This conclusion aligns with broader intelligence assessments from Baltic and Nordic states indicating Russia could develop credible offensive capabilities against the region within three to five years.
The ammunition buildup is enabled by Russia's record defense budget, which the PISM report documents in detail. The researchers stress that production will not slow even if fighting stops - and that potential sanctions relief, which Moscow is pursuing through negotiations with Washington, would further expand its industrial capacity.
The report places the ammunition surge within a broader context of force restructuring aimed at NATO's northeastern flank. New motorized rifle divisions have been deployed near the Estonian border, a new army corps has been established on Finland's frontier, and the marine brigade in Kaliningrad has been upgraded to a division. Soldiers from these formations are currently gaining combat experience on the Ukrainian front and in the Kursk region, even as they suffer heavy casualties.
For the Baltic Sea Region states, the PISM researchers recommend prioritizing the buildup of their own artillery ammunition reserves alongside investments in air defense, electronic warfare, and long-range strike capabilities. The report calls for defense spending to reach 5 percent of GDP in line with the 2025 Hague summit commitments, describing this as essential to close the widening capability gap with Russia.
