About this opportunity
Navy STTR topic — Accepting submissions 2026-12-02 to 2027-01-06. The Department of the Navy’s expanding operational requirements in the Arctic domain demand persistent subsea situational awareness. Current seabed ISR nodes and Unmanned Underwater Vehicle (UUV) docking stations rely on conventional lithium-chemistry batteries. These legacy power sources present severe logistical and operational limitations: they suffer from rapid capacity degradation in extreme cold, possess highly toxic/hazardous chemistries, and require frequent, resource-intensive physical replacement (battery swapping) in highly contested or ice-covered environments. To achieve persistent, logistics-free ISR, the Navy has a critical need for an environmentally benign, deploy-and-forget power architecture. This STTR to...
