陆军再投1.058亿美元扩建爱荷华弹药厂 155毫米炮弹新厂总投资升至7.41亿美元
美国陆军再向爱荷华陆军弹药厂追加 1.058 亿美元，用于建设一座新的 155 毫米炮弹装填综合设施。美国战争部公布的合同修改，将 MSM Group North America 公司的合同总价值提高至 7.41 亿美元，厂区定于 2029 年 8 月 10 日完工。本次修改动用 4,290 万美元 2025 财年弹药采购资金，由位于伊利诺伊州罗克岛兵工厂的陆军合同司令部管理。
这座名为“未来火炮综合设施”（Future Artillery Complex）的新厂于 2026 年 7 月 15 日破土动工，将取代爱荷华弹药厂自第二次世界大战时期沿用至今的 M795 炮弹生产线。陆军表示，旧生产线已接近使用寿命终点；新厂的设计目标是在战时可扩大产量、在平时回落至较低的维持产量，而不致因维持成本过高而难以为继。
追加投资是五角大楼推动国防工业转入战时生产水平的其中一环。战争部长皮特·赫格塞思 2025 年 11 月 7 日在国家战争学院的讲话中，把当前时期比作第二次世界大战前夕，并表示将把国防工业基础重建为战时可扩产的体系。今年与伊朗的作战已消耗美军先进弹药库存，特别是防空拦截弹。战争部副部长史蒂夫·范伯格 8 月 5 日要求国防企业在 21 天内提交扩大产能的计划。
产量数字显示扩产正在推进，但尚未达到目标。战争部监察长 2026 年 7 月 9 日的报告说，155 毫米炮弹月产量已从 14,000 发升至 2026 年 3 月的 36,000 发，弹体金属件月产量从 14,000 件升至 46,000 件；陆军未能达到 2025 年 10 月 1 日的原定目标。陆军计划到 2027 年 12 月实现每月 140,000 发的装填（LAP）产能，高于每月 100,000 发的目标。
爱荷华陆军弹药厂自 1941 年起装填弹药，位于爱荷华州东南部。陆军表示，新厂完工后，该厂的 155 毫米炮弹装填能力将成为美军火炮弹药供应链中的关键一环。
Army Adds $105.8 Million to Iowa Ammunition Plant Expansion, Bringing 155mm Complex Total to $741 Million
The U.S. Army is putting another $105.8 million into artillery production at the Iowa Army Ammunition Plant, adding to MSM Group North America's contract for a new 155mm shell loading complex. The modification, announced by the U.S. Department of War, raises the total value of the contract to $741 million and keeps completion of what the Army calls the Future Artillery Complex on schedule for August 10, 2029. The latest modification obligates $42.9 million in fiscal 2025 ammunition procurement funds, and Army Contracting Command at Rock Island Arsenal, Illinois, is managing the work.
The Army broke ground on the new plant on July 15, 2026. It will replace the Iowa plant's World War II-era M795 production line, which the Army says is nearing the end of its service life. The Army says the plant is designed to scale output for wartime surges and to drop back to a lower sustaining rate in peacetime without becoming uneconomical to run.
The contract is one piece of a broader push by the Pentagon to move the U.S. defense industry toward wartime production levels. Secretary of War Pete Hegseth laid out the policy in a November 7, 2025, speech at the National War College, in which he compared the current period to the eve of World War II and said the department would rebuild the defense industrial base for wartime expansion. Combat with Iran this year has since drawn down U.S. stocks of advanced munitions, particularly air defense interceptors. On August 5, Deputy Secretary of War Steve Feinberg gave defense companies 21 days to submit plans to expand production.
Output figures show the expansion is advancing but has not yet reached its target. A July 9, 2026, report by the Department of War Inspector General found that monthly 155mm production had risen from 14,000 to 36,000 rounds by March 2026, and output of projectile metal parts from 14,000 to 46,000. The service missed its October 1, 2025, deadline for that rate. The Army plans to reach 140,000 rounds a month of load-assemble-pack capacity by December 2027, well above the 100,000-round goal.
The Iowa Army Ammunition Plant has loaded munitions since 1941. The Army says the new complex will make the plant a key link in the supply chain for U.S. artillery ammunition once it is complete.
