On 9 October 2025, BAE Systems published an industry‑analysis arguing that commercial maritime firms, such as Ocean Infinity, are increasingly key to delivering underwater intelligence capabilities for coastal surveillance, critical‑infrastructure protection and national resilience. As part of this shift, in June 2025 BAE Systems and Ocean Infinity deployed a “lean‑crewed” survey vessel equipped with remotely operated and autonomous underwater vehicles (AUV/ROV), a broad sensor suite, and secure data links, demonstrating the ability to gather, forward and analyse subsea data in near real-time, supporting layered monitoring of seabed infrastructure and maritime approaches. The piece argues that as geopolitical tensions rise, control of the “subsea domain”, including cables, pipelines and chokepoints is becoming as strategically important as control of air or space. Commercial operators may now offer governments cheaper, more agile access to seabed data and intelligence, outsourcing much of the monitoring burden through a public–private collaboration model.
Why it matters
Undersea infrastructure is one of the most critical backbones of global connectivity and energy: fiber‑optic cables, pipelines, and data arteries pass under the waves. As state‑sponsored sabotage and “grey‑zone” maritime interference rise, traditional naval and electro‑optical surveillance is insufficient: the seabed, dark, deep, dispersed, demands persistent, autonomous, sensor‑rich monitoring that only subsea intelligence systems can deliver. By elevating commercial maritime survey firms into de facto national‑security assets, states reduce cost and increase resilience. The model lowers barriers to continuous seabed monitoring, accelerates threat detection, and provides redundancy. This shift marks a transformation: undersea infrastructure is no longer “out of sight, out of mind.” It becomes visible, monitored, and defended by a blend of commercial agility and defence‑grade discipline.
Strategic Takeaway
The future of maritime security lies beneath the waves. Nations that fail to build a robust subsea intelligence layer risk blind spots where infrastructure and sovereignty can be severed silently.
Investor Implications
Subsea‑intelligence is emerging as a new strategic segment: companies offering AUV/ROV platforms, underwater sensors, secure data links, and seabed‑data analytics will attract defence, critical‑infrastructure, and telecom investment. Investors should watch firms innovating in undersea robotics, persistent autonomous surveillance, and secure maritime data handling. As subsea threats rise, demand for maintenance, repair, mapping, and continuous monitoring services may grow creating recurring-revenue opportunities. Additionally, governments may increasingly outsource parts of underwater defence to commercial partners, altering the procurement and contract landscape in defence and critical‑infrastructure protection.
Watchpoints
Q2 2026 → Further NATO or national defence contracts awarded to commercial subsea‑intelligence providers following Baltic and North‑Sea cable disruption incidents.
2026–2027 → Release of a whitepaper or regulation defining national standards for subsea‑infrastructure monitoring and intelligence data sharing.
2026 → Expansion of commercial‑defence joint deployments of AUV/ROV fleets with real‑time data feed into sovereign networks.
Tactical Lexicon: Subsea Intelligence
A coordinated system of autonomous or remotely operated underwater vehicles (AUV/ROV), sensor networks and data‑transmission pipelines designed to monitor, map, and secure seabed infrastructure and maritime approaches.
Why it matters:
Turns once‑invisible undersea infrastructure into a monitored domain.
Enables early warning, detection of sabotage or intrusion, and seabed-domain situational awareness pivotal for national resilience and strategic deterrence.
