What Happened
- India's Chief of Naval Staff, Admiral Dinesh K. Tripathi, warned at the International Conference on India-Japan Cooperation in the Indo-Pacific (New Delhi, March 24, 2026) that unmanned systems and sea mines are now capable of effectively choking critical maritime passages like the Strait of Hormuz without a formal blockade being declared.
- The Admiral highlighted that asymmetric tools — drones and remotely deployed mines — create de facto maritime disruption at a fraction of the cost of conventional naval operations.
- He identified information warfare as generating a new class of global choke points: undersea cables and their associated infrastructure have become vulnerable nodes that can be targeted to sever global communications networks.
- The remarks come in the context of ongoing Houthi drone and missile attacks on commercial shipping in the Red Sea and evolving threats in the Strait of Hormuz region, illustrating how non-state actors can hold global trade hostage.

Maritime Choke Points and Global Trade
A maritime choke point is a narrow navigable passage through which large volumes of global seaborne trade must pass, making it a critical node in the global supply chain. The Strait of Hormuz — located between Iran and Oman, connecting the Persian Gulf to the Gulf of Oman — is the world's most important oil transit choke point. In 2024, approximately 20 million barrels of oil per day transited it, representing about 20% of global petroleum consumption and more than one-quarter of all seaborne oil trade. Around one-fifth of global LNG trade also passes through Hormuz, mainly from Qatar. Other critical choke points include the Strait of Malacca (connecting the Indian Ocean to the Pacific, crucial for Asia-bound cargo), and the Bab-el-Mandeb (connecting the Red Sea to the Gulf of Aden, on the route to the Suez Canal). A closure or disruption — even temporary — causes substantial supply delays and price spikes globally.
- Hormuz: ~104 miles long, narrows to 21 nautical miles at its tightest point; only sea passage from the Persian Gulf to the open ocean
- Strait of Malacca: ~900 km long; about 40% of world trade passes through it annually
- Bab-el-Mandeb: connects Red Sea and Gulf of Aden; ~30 km at narrowest; Houthi attacks since 2023 diverted major shipping lines away from the Suez route
- Most Hormuz-bound oil has no viable alternative pipeline route out of the region
- India imports over 80% of its crude oil; any Hormuz disruption directly affects India's energy security
Connection to this news: Admiral Tripathi's warning that drones and mines can create a "virtual blockade" without formal declaration means choke points like Hormuz face permanent threat from asymmetric actors, elevating the strategic cost of India's energy dependence on the Gulf.
Drone Warfare in the Maritime Domain
Unmanned systems — including unmanned surface vehicles (USVs), unmanned underwater vehicles (UUVs), and aerial drones — have fundamentally altered naval threat calculus. In asymmetric maritime conflict, low-cost drones allow non-state actors and smaller navies to threaten expensive warships and commercial vessels. The Houthi campaign against Red Sea shipping (2023–present) demonstrated that armed drones and anti-ship missiles can force major commercial operators to reroute thousands of kilometres, costing the global economy billions of dollars per month. Acoustic and magnetically triggered sea mines are another asymmetric tool: cheap to deploy but extremely costly to detect and remove. Mine-clearing operations require specialised vessels, significant time, and place mine-clearance divers at risk.
- One-way attack drones (loitering munitions) can be procured for $20,000–$50,000 versus the hundreds of millions of dollars cost of a naval vessel they can threaten
- Anti-drone systems (CIWS, laser weapons, electronic jamming) are still evolving and expensive
- India's Navy has been investing in drone surveillance and the DSAPT (Defence Space and Autonomous Platform Technologies) programme
- Freedom of Navigation Operations (FONOPs) — naval patrols asserting international waters rights under UNCLOS — are a key tool to counter maritime intimidation short of formal blockade
Connection to this news: The Navy chief's assessment reflects India's growing concern that non-state and state-sponsored actors can weaponise cheap drone and mine technology to disrupt choke points critical to India's trade and energy supply.
Undersea Cables as Critical Infrastructure
More than 95% of all international internet and financial data travels through approximately 400 undersea cable systems totalling over 1.3 million kilometres globally. Undersea cables carry an estimated $10 trillion worth of financial transactions daily. Their physical vulnerability — cables run along the seabed and can be cut by anchors, fishing nets, or deliberate sabotage — has made them a new front in information and hybrid warfare. In 2024 and 2025, several incidents of suspected deliberate cable damage in the Baltic Sea and the Red Sea raised alarm in NATO countries and India alike. India is a hub for Indo-Pacific cable landings; major cable landing stations are located in Mumbai, Chennai, and Kochi.
- Cable repair vessels are few (roughly 60 globally) and take weeks to deploy, meaning even temporary cuts create prolonged outages
- UNCLOS does not provide robust protection for undersea cables beyond territorial waters
- India's National Security Council has flagged undersea cable protection as part of its maritime security doctrine
- The term "choke point" in the information warfare context refers to nodes where cables can be most efficiently severed or tapped — near landing stations, in shallow water near coastlines
Connection to this news: Admiral Tripathi explicitly cited undersea cables as a new class of global choke point created by information warfare, placing cyber-physical infrastructure alongside geography in India's maritime threat matrix.
India's Maritime Security Doctrine
India's maritime interests span three key theatres: the Arabian Sea (west), the Bay of Bengal (east), and the Indian Ocean at large. India's Maritime Security Strategy (2015, updated 2023) identifies protection of sea lines of communication (SLOCs) and chokepoint access as core national interests. The Indian Navy operates as the net security provider in the Indian Ocean Region (IOR), cooperating with regional navies under frameworks like IORA (Indian Ocean Rim Association) and bilateral exercises such as JIMEX (India-Japan Maritime Exercise) and MALABAR.
- India's "SAGAR" (Security And Growth for All in the Region) doctrine articulates a rules-based maritime order commitment
- India is a member of the Quad (India, US, Australia, Japan), which includes a Maritime Domain Awareness (MDA) initiative
- The Indian Navy has deployed anti-piracy patrols in the Gulf of Aden continuously since 2008
- INS Vikrant (commissioned 2022) is India's first domestically built aircraft carrier, enhancing power projection capability in the IOR
Connection to this news: The Navy chief's conference remarks contextualise India's growing investment in drone countermeasures, undersea cable monitoring, and multilateral maritime frameworks as direct responses to the emerging asymmetric threat landscape he described.
