Taiwan’s defense sector is ramping up efforts to bolster its artillery ammunition capabilities through a groundbreaking joint production deal with the United States. Lt. Gen. Lin Wen-hsiang, head of Taipei’s Armaments Bureau, announced the preliminary work on co-producing 155mm artillery shells, a critical NATO-standard munition in high global demand. This move comes as Taiwan faces escalating threats from China, including potential blockades that could disrupt vital supply chains for military hardware.
The partnership directly ties into Taiwan’s anticipated delivery of US-made M109A7 self-propelled howitzers later this year. Officials note that current Taiwanese homegrown 155mm shells face compatibility issues with the M109A7’s stringent US specifications. By aligning production to these standards, the collaboration aims to ensure seamless integration, enhancing Taiwan’s artillery firepower for long-range strikes, counter-battery missions, and troop support operations.
To support this initiative, Taiwan’s Ministry of National Defense has allocated approximately 14 billion New Taiwan dollars (about $443 million) for infrastructure upgrades. This includes constructing an automated production line at the Armaments Bureau’s 202nd Factory and modernizing facilities to surge output of 155mm rounds and other high-demand munitions. These 155mm shells, roughly 2 feet long and weighing 100 pounds, power systems like the M109 Paladin, Panzerhaubitze 2000, and CAESAR howitzers.
Should the US-Taiwan 155mm artillery shell project succeed, expansion to additional weapons and munitions is on the table, echoing Washington’s 2022 considerations for broader co-production, including technology transfers and hybrid manufacturing with Taiwan-sourced components. This development underscores Taiwan’s push for ammunition self-reliance, inspired by the Ukraine-Russia war’s lessons on 155mm shell shortages.
Globally, nations are racing to secure 155mm artillery ammunition supplies amid surging demand. The US Army is pouring nearly $640 million into high-explosive rounds via its Special Ammunition and Weapons Systems program, targeting 100,000 rounds monthly by mid-2026. In Europe, Poland partners with BAE Systems and Polska Grupa Zbrojeniowa for a new facility, while Belgium inaugurates a Wallonia-based line to cut foreign dependency.
