India’s 200-Warship Surge Targets China as Pakistan’s Hangor Submarines Reshape the Indian Ocean

(DEFENCE SECURITY ASIA) — India is accelerating toward a fleet exceeding 200 warships and submarines by 2035, transforming an established modernisation programme into an urgent response to China’s expanding Indian Ocean presence and Pakistan’s acquisition of advanced Chinese-designed air-independent-propulsion submarines.

The expansion matters beyond hull numbers because New Delhi is attempting to generate persistent sea control, distributed deterrence, and resilient logistics across an ocean carrying critical global trade and energy flows between the Indo-Pacific, Middle East, Africa, and Europe.

India currently operates approximately 140 to 150 ships and submarines, including roughly 135 frontline combatants, while an estimated 45 to 54 additional vessels are under construction across public and private shipyards supporting the expanding naval force structure.

Commissioning has accelerated toward one domestically built warship or submarine every 40 days to six weeks, with approximately 10 to 12 platforms inducted during 2025, followed by plans for 19 during 2026 and 13 during 2027.

That production rhythm could expand the fleet to approximately 150–160 warships by 2030, more than 200 naval vessels by 2035, and potentially around 230 surface combatants and submarines by 2037 after accounting for ageing-platform retirements.

The strategic objective is not numerical equivalence with China’s fleet of more than 370 battle-force ships, but sufficient networked combat power to exploit India’s geography, protect sea lanes, monitor chokepoints, and contest hostile submarines throughout the Indian Ocean Region.

Pakistan’s eight Hangor-class diesel-electric attack submarines sharpen that requirement because their Chinese Type 039A/Yuan-derived design and air-independent propulsion can increase submerged endurance, complicating detection in the Arabian Sea and stretching India’s anti-submarine warfare coverage across two maritime axes.

The first boat, PNS Hangor, entered service in China during April 2026 under an approximately US$5 billion, or RM20 billion, programme dividing construction between four Chinese-built and four Pakistani-built submarines while transferring manufacturing knowledge to Islamabad.

India’s answer combines Project 75I conventional submarines, Project 77 nuclear-powered attack submarines, indigenous surface combatants, aircraft-carrier options, maritime aviation, unmanned systems, and forward infrastructure across the Andaman and Nicobar Islands and Lakshadweep rather than relying upon one platform category.

This expansion is anchored in “Atmanirbhar Bharat,” India’s self-reliance policy, which makes domestic design, construction, maintenance, and supply-chain resilience operational requirements because a wartime fleet unable to replace components or repair combat damage cannot sustain credible maritime deterrence.

Recent inductions, including the Project 17A Nilgiri-class stealth frigate INS Mahendragiri and Mahe-class anti-submarine warfare shallow-water craft INS Malvan, demonstrate how high-end escort capacity and littoral undersea surveillance are being expanded simultaneously within the indigenous shipbuilding pipeline.

Nevertheless, achieving the declared force structure depends upon sustained financing, shipyard expansion, specialised steel, skilled labour, propulsion development, sensor and weapon localisation, and disciplined programme sequencing, leaving the 200-ship objective credible but exposed to industrial delays and retirement-driven capability gaps.

A 200-Ship Fleet Built for Sea Control, Not a Symbolic Hull Count

India’s fleet roadmap links approximately 13 destroyers and 20 frigates carrying more than 300 BrahMos missiles by around 2030 with corvettes, missile vessels, mine countermeasure ships, amphibious platforms, replenishment vessels, patrol craft, and survey ships supporting sustained combat operations.

Project 17A represents the near-term surface-combatant foundation because its Nilgiri-class frigates combine stealth shaping, guided weapons, and more than 75 percent indigenous content, strengthening escort density while giving Indian yards repeatable experience integrating increasingly complex sensors and combat systems.

The follow-on Project 17B envisions six approximately 8,000-tonne frigates under a roughly ₹40,000 crore programme, equivalent to about US$4 billion or RM16 billion, although a request for proposals around 2027 would place meaningful construction activity closer to 2031.

Destroyer growth follows a similarly layered sequence, moving from Project 15B Visakhapatnam-class ships toward four Project 15C vessels and six larger Project 18 combatants displacing approximately 14,000–15,000 tonnes, with procurement and construction extending into the next decade.

Those timelines matter because larger combatants provide magazine depth, command capacity, long-range air defence, and strike reach, yet delays could leave fewer available escorts precisely when Chinese submarine deployments, carrier operations, and long-distance task groups become more frequent.

Sixteen anti-submarine warfare shallow-water craft from the Arnala and Mahe classes address a different battlespace, concentrating sonar coverage, underwater surveillance, mine-laying capacity, and low-intensity response within congested littoral approaches where conventional blue-water escorts would be inefficiently employed.

Eight next-generation corvettes, next-generation missile vessels, and 12 mine countermeasure ships would broaden distributed lethality while protecting naval bases and commercial approaches, because an adversary can constrain a superior fleet by mining ports, threatening choke routes, or saturating limited escorts.

Four proposed landing platform docks exceeding 32,000 tonnes would add helicopters, drones, substantial armament, and integrated electric propulsion, enabling expeditionary lift, disaster response, island reinforcement, and distributed command functions without treating amphibious warfare as separate from Indian Ocean deterrence.

Support vessels remain strategically decisive because carrier groups, submarine patrols, and dispersed surface formations require replenishment, repair access, ammunition handling, and protected logistics nodes, meaning fleet endurance will be determined as much by auxiliaries and shipyard throughput as missile inventories.

The resulting force is intended to support at least two highly mobile, self-contained fleets, allowing India to maintain concurrent presence across western and eastern approaches while retaining reserve capacity for escalation, maintenance cycles, sea-lane protection, and coalition exercises throughout the Indo-Pacific.

The Hangor Programme Turns India’s Submarine Gap Into an Operational Deadline

India fields approximately 16 diesel-electric submarines and three nuclear ballistic-missile submarines, but older conventional boats may retire before replacement programmes deliver at scale, creating a temporary numerical and availability trough during a period of intensifying regional undersea competition.

Pakistan’s Hangor programme changes the tactical equation because eight air-independent-propulsion submarines can remain submerged longer than conventional battery-dependent boats, reducing exposure during snorkelling and increasing uncertainty for Indian commanders protecting carrier groups, ports, merchant routes, and strategic submarine operating areas.

The programme’s roughly US$5 billion, or RM20 billion, value also finances technology transfer through Pakistani construction of four vessels, potentially improving local maintenance, repair, training, and future production capacity rather than delivering an isolated acquisition dependent entirely upon Chinese facilities.

Project 75I is therefore strategically important, with six air-independent-propulsion submarines expected around a preferred enlarged German Type 214-derived design and Mazagon Dock partnership, although contract finalisation and construction lead times could delay the first boat until the mid-2030s.

Six Kalvari/Scorpène-class submarines remain the conventional core, while slowly progressing air-independent-propulsion upgrades and discussions concerning additional Scorpènes reflect a bridge requirement created by ageing hulls, delayed procurement, and the need to preserve crews and industrial competence before Project 75I matures.

Project 76 could eventually add as many as 12 indigenous conventional submarines, but its early development status means it cannot solve near-term force availability, requiring planners to balance design sovereignty against the operational cost of waiting for domestically controlled technologies.

At the nuclear level, indigenous Project 77 envisages six approximately 10,000-tonne attack submarines, with the first two approved and initial delivery targeted around 2036–2037, providing sustained speed, endurance, and possible vertical-launch capacity for cruise or hypersonic weapons.

The delayed Russian Akula-class Chakra-III lease, now expected around 2028, may preserve nuclear-attack-submarine experience, yet one leased platform cannot provide continuous multi-axis coverage against Chinese deployments, protect ballistic-missile submarines, and independently conduct surveillance or sea-denial missions.

India’s ballistic-missile-submarine force includes three active Arihant-class boats, another undergoing trials, and larger planned S5-class submarines displacing about 13,500 tonnes, whose survivability ultimately depends upon protected bastions, effective anti-submarine warfare screens, and secure command-and-control connectivity.

Closing the undersea gap therefore requires more than submarine procurement, demanding maritime patrol aircraft, helicopters, seabed awareness, unmanned underwater vehicles, littoral craft, acoustic intelligence, maintenance infrastructure, trained crews, and integrated targeting networks capable of converting detections into timely engagements.

Andaman and Nicobar Basing Repositions India Beside the Malacca Approaches

The Andaman and Nicobar Command gives India geographic leverage near approaches to the Malacca Strait, where surveillance aircraft, ships, submarines, and sensors can monitor traffic moving between the South China Sea and Indian Ocean without matching China platform for platform.

Strengthening these islands changes force posture by shortening Indian response distances, extending maritime domain awareness, and creating options for interdiction or shadowing, although forward operating effectiveness still depends upon runway resilience, fuel storage, ammunition protection, repair capacity, and layered air defence.

The Great Nicobar Island Development Project combines military utility with civil infrastructure through a greenfield airport, international container transshipment terminal, power plant, township, and facilities at Galathea Bay, potentially converting an austere outpost into a sustainable logistics and surveillance hub.

The planned approximately three-kilometre runway, under naval operational control and expected to require about five years for completion, could support larger aircraft and higher sortie generation, strengthening reconnaissance, anti-submarine warfare, transport, refuelling, and rapid reinforcement across the eastern Indian Ocean.

The airport component, valued around ₹13,000 crore or approximately US$1.3–1.5 billion and RM5.2–6 billion, illustrates the scale of investment required to turn geographic proximity into persistent combat power rather than episodic patrols unsupported by adequate sustainment.

Existing facilities such as INS Baaz would be complemented rather than merely enlarged, creating multiple operating locations that complicate hostile targeting and distribute aircraft, sensors, personnel, fuel, and communications while reducing dependence upon vulnerable mainland bases during a regional contingency.

Parallel improvements in Lakshadweep would strengthen western coverage toward the Arabian Sea, where Pakistan’s submarine fleet and shipping routes demand different patrol patterns, allowing India’s two-fleet concept to rest upon geographically separated but operationally connected island infrastructure.

Chinese survey and research vessels intensify this contest by collecting bathymetric, acoustic, and environmental information around ridges, chokepoints, and island approaches, data that can improve submarine navigation, sonar performance prediction, anti-submarine tactics, and future underwater sensor-network design.

Frequent Chinese anti-piracy deployments and access to ports including Gwadar, Hambantota, and facilities in Myanmar and Bangladesh do not automatically establish wartime bases, but they can build familiarity, relationships, replenishment options, and logistics intelligence relevant during future crises.

India’s island strategy consequently links sensors to shooters and bases to sustainment, because surveillance without deployable interceptors produces awareness without control, while combat ships without secure fuel, repair, aviation, and communications cannot maintain the persistent presence demanded by maritime deterrence.

Carriers, Maritime Aviation and Networked Combat Power Define Fleet Quality

India operates INS Vikramaditya and the domestically built INS Vikrant, giving the navy two carrier hulls, yet maintenance cycles mean nominal ownership does not guarantee simultaneous availability for western and eastern fleets during prolonged tension or an unexpected regional confrontation.

A second improved Vikrant-class carrier could preserve construction skills and fleet commonality, whereas the proposed INS Vishal, or IAC-3, would pursue a 65,000–75,000-tonne CATOBAR configuration with electromagnetic catapults and capacity for more than 50 fighters, helicopters, unmanned aircraft, and airborne early-warning platforms.

The larger carrier remains a planning proposition because cost, nuclear-propulsion options, electromagnetic-launch technology, aircraft selection, escort requirements, and shipyard capacity must be resolved before its projected air wing can generate operational advantage rather than consume resources needed by submarines and escorts.

Carrier effectiveness depends upon airborne early warning, fighter range, anti-submarine helicopters, aerial refuelling, electronic warfare, secure datalinks, and replenishment, making the aviation arm’s planned growth beyond roughly 250 aircraft and helicopters central to fleet survivability against long-range missiles and submarines.

Hundreds of future aircraft and helicopters would enlarge surveillance and engagement coverage, but expansion demands trained aircrew, maintainers, spare engines, deck-handling systems, weapons stocks, simulators, and protected airfields, creating a logistics burden that must grow alongside platform procurement.

Networked capability is particularly important against China because distributed sensors on islands, aircraft, surface ships, submarines, satellites, and unmanned systems must produce a common operating picture before commanders can assign scarce weapons against fleeting or low-signature maritime targets.

India’s planned extra-large unmanned underwater vehicles and special-forces midget submarines could extend reconnaissance, seabed monitoring, covert insertion, and mine-related missions, reducing risk to crewed platforms while complicating adversary calculations across ports, littorals, and strategic maritime approaches.

BrahMos-equipped destroyers and frigates provide substantial offensive reach, yet missile numbers alone cannot secure sea control because targeting data must remain accurate throughout the engagement cycle, especially against moving warships protected by electronic warfare, decoys, layered defences, and emission-control procedures.

Quality therefore means integrating magazines, sensors, aviation, undersea assets, cyber-resilient communications, and logistics into a system of systems, while sustaining enough hulls at readiness to cover maintenance, training, deployments, escalation reserves, and losses without hollowing the nominal fleet.

The 200-ship benchmark is consequently best understood as the physical foundation for persistent, networked combat power, not an endpoint, because readiness rates, weapon stocks, crew proficiency, forward sustainment, and decision speed will determine whether numerical expansion changes the regional battlespace.

Industrial Self-Reliance Will Decide Whether Ambition Becomes Enduring Sea Power

The handover of Russian-built INS Tamal during 2025 marked the expected end of foreign-origin warship deliveries, signalling that future fleet growth should emerge primarily from Indian yards even where propulsion, sensors, weapons, or specialist technologies still involve foreign collaboration.

Construction is spread across Mazagon Dock, Garden Reach, Cochin Shipyard, Hindustan Shipyard, Larsen and Toubro, and other facilities, distributing workload and industrial knowledge while creating coordination challenges involving design standards, suppliers, skilled labour, testing infrastructure, and delivery schedules.

Recent estimates valued ships under construction at approximately ₹99,500 crore, roughly US$10 billion or RM40 billion, while accepted requirements covering more than 65 surface ships and several submarines exceeded ₹2 lakh crore, approximately US$20 billion or RM80 billion.

An additional maritime package of about US$8.4 billion, equivalent to RM33.6 billion, seeks to place India among the world’s leading shipbuilding nations by 2047, linking naval demand with commercial capacity, employment, supplier development, and long-term industrial competitiveness.

Indigenous content is estimated near 90 percent for hulls and fittings, approximately 60 percent for propulsion, and around 50 percent for sensors and weapons, revealing that visible ship construction has advanced faster than sovereignty over several high-value combat-system dependencies.

Selective cooperation with France, Germany, Russia, the United States, Israel, and Japan can close those gaps through submarine design, propulsion, sensors, weapons, stealth masts, or potential frigate co-production, provided technology transfer strengthens domestic sustainment rather than creating new external bottlenecks.

Shipyard capacity, specialised steel, critical components, experienced naval architects, nuclear expertise, and systems-integration skills remain finite, while competition from commercial sectors can drain trained workers, making human capital and supplier continuity as consequential as headline defence allocations.

Naval fleet capital funding has recently remained around ₹24,000–25,000 crore annually, approximately US$2.4–2.5 billion or RM9.6–10 billion, creating potential tension between current procurement capacity and simultaneous demands from submarines, carriers, destroyers, aviation, infrastructure, and weapons replenishment.

Competing army and air-force priorities intensify that pressure, while retirements mean every delayed replacement can reduce operational strength before new construction expands it, turning procurement sequencing and maintenance planning into strategic variables rather than administrative details within India’s modernisation effort.

India can plausibly exceed 200 naval vessels if political commitment, capital investment, industrial reform, and technology absorption remain sustained, but credible sea power will ultimately depend upon closing the undersea gap and converting domestic production momentum into deployable, supplied, networked readiness.
