The next great power contest is unfolding far from the public eye — deep beneath the surface of the world’s oceans. Subsea warfare is rapidly becoming the most important military domain of the 21st century, shaping global power, energy security, digital connectivity, and nuclear stability.In this in-depth Strategic Vanguard analysis, I break down how the world’s superpowers — the United States, China, and emerging regional players — are fighting a silent, high-stakes contest under the sea. From undersea fibre-optic cables and nuclear-armed submarines to AI-driven underwater drones and seabed surveillance networks, this is a battlefield India cannot afford to ignore.This episode explores:Why 95% of the world’s digital communications run through the seabedChina’s “Great Underwater Wall” and massive autonomous drone fleetThe US DARPA Hydra program and future undersea mothershipsHow subsea warfare threatens India’s economy, security, and nuclear deterrenceWhy the Andaman & Nicobar Islands are becoming a critical chokepointWhat India’s strategic roadmap must be for underwater dominanceIf the wars of the past were fought on land, sea, and air, the wars of the future will be fought in the deep — unseen, unheard, and unacknowledged.Subscribe to Strategic Vanguard for more deep-dive geopolitical, military, and strategic analyses from an Indian perspective.Our website- https://strategicvanguard.com/Manoj Ambat’s Personal Website- https://www.manojambat.in/Strategic Vanguard @ Youtube- https://www.youtube.com/@StrategicVanguard Join us to discuss deep in Strategic Vanguard groups : https://www.strategicvanguard.com/groupsStrategic Vanguard @ Facebook: https://www.facebook.com/strategicvanguardStrategic Vanguard @X (Formerly Twitter)- https://x.com/StrategicVangu1Strategic Vanguard @ Instagram- https://www.instagram.com/strategicvanguard/Strategic Vanguard @ Quora- https://strategicvanguard.quora.com/ Strategic Vanguard @ Medium: https://medium.com/@strategicvanguard1Strategic Vanguard @ Reddit- https://www.reddit.com/r/strategicvanguard/Strategic Vanguard@ Telegram - https://t.me/strategicvanguardStrategic Vanguard@Tumblr: https://www.tumblr.com/blog/strategicvanguardStrategic Vanguard@ BlueSky: https://bsky.app/profile/strategicvanguard.bsky.socialStrategic Vanguard@Substack- https://strategicvanguard.substack.com/#SubseaWarfare #IndianNavy #Geopolitics #IndoPacific #UnderseaCables #China #USA #India #NavalPower #MilitaryTechnology #StrategicVanguard #AUKUS #SouthChinaSea #NationalSecurity #FutureOfWarfare #MaritimeSecurity
