在第二次世界大战中,美国曾经兴建了13家轻武器弹药厂。战后一些工厂关闭了,在朝鲜战争期间,这些弹药厂又重新启用。目前,陆军只有两家生产轻武器弹药的工厂,一家是湖城陆军弹药厂,它是眼下陆军唯一一家开工的弹药厂;另一家是双城陆军弹药厂,该厂曾经生产过轻武器弹药和炮弹。美国轻武器弹药工业,除了这两家国有私营的工厂外,还包括了部分私有厂商。美国陆军曾经采取鼓励尽量从私有工厂购买和生产弹药的政策,尤其是枪弹一类的小口径弹药,因为步枪弹和卡宾枪弹与运动枪弹非常相似,生产技术和生产线几乎是相同的。美国私有轻武 During the Second World War, the United States once built 13 small arms ammunition plants. Some factories were closed after the war and the ammunition factories were reactivated during the Korean War. Currently, the Army has only two factories that produce small arms ammunition, one that is the Lake City Army Ammunition, the only one that the Army is now launching, and the other, the Twin Cities Army Ammunition, which used to produce light weapons ammunition and artillery shells. The U.S. small arms and ammunition industry, in addition to the two state-owned private factories, also includes some private manufacturers. The United States Army has adopted policies that encourage the purchase and production of ammunition from private factories to the extent possible, particularly small-caliber ammunition such as bullets, since the rifle and carbine shells are very similar to those of sport bullets and the production technology and production lines are almost the same.
