To that extent, they have funded a four-year research project in which they have awarded an $8 million contract to the University of Illinois Chicago. This project will see researchers work on a system that can autonomously charge drones, where there could be charging stations setup at various locations, and drones will be able to search for the nearest one and automatically fly there to recharge when it is low on battery.
While this doesn’t exactly solve the short battery life on drones, the fact that these drones can automatically seek out the nearest charging station means that soldiers won’t need to manually charge drones nor carry about battery packs, thus lessening their load and freeing up time to do other things.
What’s interesting about this project is that Amazon has actually conceived of something similar. Back in 2017, a patent was discovered where Amazon envisioned a possible drone hive where drones could be deployed from and return to.
