This bill modifies an existing Department of Defense demonstration and prototyping program focused on contested logistics environments. Its primary purpose is to expand the scope of this program to specifically include commercial additive manufacturing facilities . By incorporating these facilities, the bill seeks to enable the rapid, distributed production of parts closer to the point of use, thereby enhancing logistical support capabilities in challenging operational settings. Furthermore, the legislation extends the program's authorization, pushing its sunset date to December 31, 2030 , allowing for a longer period of development and implementation.
