Manufacturing woes hamper US 155-mm ammo production

The U.S. Army is failing to meet its goal of producing 100,000 155-mm howitzer shells monthly by October 2025, with only 36,000 rounds produced as of March 2026. Manufacturing bottlenecks at a Texas facility operated by General Dynamics, which struggles to meet specifications for projectile metal parts, are cited as the primary issue. The Army adapted outdated equipment from the 1958-era M107 shell design, exacerbating production delays.
