U.S. Army DEVCOM Armaments Center has established leading laboratory, power source prototyping, and testing capabilities for the development and evaluation of next generation munition power sources. The expanded prototyping capabilities include the ability to integrate novel materials into in-house fabricated prototype power sources, such as thermal reserve batteries. Unique testing facilities are then utilized to evaluate the thermal reserve battery prototypes under representative gun-launch environments enabling the ability to raise the technology from TRL 2 to TRL 6 and beyond. This presentation will highlight the exclusive laboratory, prototyping, and testing capabilities, as well as offer opportunities to partner on collaborative projects with the goal to innovate fuze and munitions power sources.
