I'm working on a concept for a passive underwater device. The probe stays dormant underwater, equipped with sensors and a basic AI module. When triggered (by a timer or environmental input), it surfaces and emits short coded optical signals (LED/IR/laser). Optional support for GPS and Iridium satellite uplink.

Potential use-cases I'm exploring: – Acts as a decoy to provoke sonar activity – Mass deployment for presence simulation – Environmental and educational applications

I call this concept NUTRA: Naval Underwater Triggered Response Architecture.

My question to HN: Could a low-cost, passive, behavior-based platform like this realistically shift assumptions in modern naval defense or reconnaissance?

Where are the blind spots in this logic? What weaknesses am I overlooking?
