Seasats Lightfish long-endurance USV operates near Chinese Type 052D

The post describes the Seasats Lightfish, a small solar/hybrid uncrewed surface vessel capable of months-long endurance, operating autonomously across the Pacific and approaching a Chinese destroyer while tracking it via onboard radar and video. The novelty is the practical demonstration of persistent, low-cost USVs operating in contested waterways and creating new rules-of-engagement and force-protection challenges for navies.
