Denmark Acquires Spare Gun Barrels after Learning from Ukraine War Experience

The Danish Armed Forces will acquire additional spare gun barrels for tanks, artillery, and mortar systems following combat lessons drawn from the war in Ukraine, where intense usage has led to rapid barrel wear and reduced weapon accuracy.

The decision follows close cooperation between Denmark and Ukraine, with Danish defense officials studying the operational challenges Ukrainian forces face in their ongoing conflict with Russia. A key takeaway has been the need to maintain a reserve stock of cannon barrels to sustain firepower in prolonged combat scenarios.

"Gun barrels are not built to last forever—especially not under heavy use," said Danish Minister of Defense Troels Lund Poulsen. "The Ukrainians’ experience shows us that worn-out barrels can compromise a weapon’s effectiveness. This acquisition is essential for the continued strengthening of Denmark’s defense capability."

The Danish military will now purchase spare barrels for the Leopard 2 main battle tanks, the ATMOS self-propelled artillery system, and the CARDOM mortar system. The total investment is estimated at DKK 230 million, financed through Denmark's Acceleration Fund, which is dedicated to enhancing military readiness.

The procurement will be phased in over the coming years, based on a recommendation from the Chief of Defense. The move is part of a broader effort to reinforce operational endurance across Danish Army units.

"The Ukrainian battlefield shows us that endurance depends on having key spare parts at hand," said Major General Peter Boysen, Commander of the Army. "Gun barrels wear down and can compromise accuracy. By securing spare barrels, we strengthen the Army’s ability to fight effectively over time."

The spare parts acquisition falls under the broader Agreement on Strengthening the Armed Forces' Combat Power, which allocates DKK 50 billion ($7.36 billion) for defense improvements, including DKK 25 billion ($3.68 billion) earmarked for 2025 and 2026 through the Acceleration Fund. An additional DKK 10 billion ($1.47 billion) annually from 2027 to 2033 will support related initiatives such as equipment purchases, infrastructure upgrades, and personnel growth.
