# Autonomous Undersea System **Entity class:** Military system class **Domain:** Defense / Undersea autonomy **Maturity:** Developed ## Definition An autonomous undersea system is an uncrewed vehicle or sensor platform able to operate underwater with limited communication and varying degrees of onboard decision-making. ## Mechanism and significance Because radio communication attenuates underwater, these systems often require greater local autonomy than comparable surface platforms. ## Relationships - **Research dossier:** [[research/ASI and RSI Timeline Research Moonshots|ASI and RSI Timeline Research Moonshots]] - **Ontology route:** [[ASI and RSI Timeline Ontology#Autonomous Warfare and Strategic Systems|Autonomous Warfare and Strategic Systems]] - **Primary fields:** [[Autonomous Weapons]] · [[AI Superpower]] · [[Machine Succession]] - **Adjacent concepts:** [[Lunar Military Infrastructure]] · [[Seabed Warfare]] · [[Hunt Mode]] · [[Communications-Denied Autonomy]] ## Sources and provenance - [[research/ASI and RSI Timeline Research Moonshots|ASI and RSI Timeline Research Moonshots]] — immediate source for this node's role in the broadcast research map. ## Evidence boundary The research dossier establishes why this entity or concept belongs in the Moonshots ontology.
