Ethics and safety constraints 1. Strictly follow the compliance review of autonomous weapon systems under international maritime conventions 2. Design a multi-level manual intervention mechanism (including optical question-and-answer verification, quantum key self-destruct command) 3. Establish an interpretative framework for the decision-making process (post-mortem analysis module based on SHAP value) The current technology maturity (TRL) has reached level 5 (component-level verification), and the next step needs to focus on breaking through the problem of multi-agent collaboration in a complex electromagnetic environment. The actual deployment also needs to solve the impact of underwater communication delay (currently >500ms) on distributed decision-making, as well as the problem of model drift in long-term tasks.
