For the Indian Navy, TPCR-2025 is not just a procurement roadmap. It is a strategic vision for the next 10–15 years of maritime power, shaping what India’s force structure must look like in the 2030s and beyond. At its heart lies an ambition: to field a nuclear-powered, indigenous, technology-driven fleet that can project power across the Indo-Pacific and secure India’s sea lines of communication.
This ambition comes against a changing regional backdrop. The People’s Liberation Army Navy (PLAN) has expanded at a breathtaking pace, commissioning new destroyers, carriers, and submarines every year. China’s aircraft carriers—including the Fujian with electromagnetic catapults—are designed for power projection well into the Indian Ocean. Pakistan, though smaller, is steadily investing in submarines and guided-missile frigates. India cannot afford to lag behind.
The Carrier as the Symbol of Ambition
The Navy’s demand for a third aircraft carrier, nuclear-powered, is the boldest entry in TPCR-2025. Unlike conventionally powered carriers, a nuclear carrier has unlimited endurance. It can remain at sea for years without refuelling, enabling sustained deployments across the Indo-Pacific.
Equally transformative is the call for Electromagnetic Aircraft Launch Systems (EMALS), two are listed in the plan. India’s current carriers rely on ski-jump launch systems, which limit the weight of aircraft that can take off. EMALS, by contrast, can launch heavier fighters, airborne early-warning aircraft, and even unmanned combat aerial vehicles (UCAVs). This dramatically increases the carrier’s strike power and versatility.
The air wing itself is central to the Navy’s indigenisation agenda. The Twin-Engine Deck-Based Fighter (TEDBF) designed by ADA and to be produced by HAL will be the first indigenous combat jet to operate from an Indian carrier. It will be joined by multi-role deck helicopters and, potentially, stealth UCAVs. Together, this marks a generational leap in India’s carrier aviation.
Tech Snapshot: Nuclear Carrier & Air Wing
| System | Specifications / Features | Significance |
| Nuclear Propulsion (carrier & select surface combatants) | TPCR lists ~10 propulsion plants (indicative) | Endurance & Indo-Pacific reach; entry into nuclear surface fleet |
| EMALS | Qty 2; electromagnetic launch of heavy fighters, AEW aircraft & UCAVs | Leap beyond ski-jump limitations |
| Carrier Air Wing | TEDBF (ADA/HAL) + multi-role deck helicopters | First indigenous carrier fighter integration |
| UCAV Operations | Stealth unmanned combat aerial vehicles | Expands ISR and strike at sea |
Surface Combatants: The Backbone of Sea Control
To support the carrier battle group, TPCR-2025 lists requirements for a new generation of surface combatants. These include 5–10 destroyers and frigates equipped with advanced radars, vertical launch missile systems (VLS), and integrated EW suites. Designed for both air defence and anti-submarine warfare, these ships will form the backbone of sea control missions.
The roadmap also includes 7 corvettes, optimised for littoral warfare and escort roles, and ≥5 fleet support ships of 44,000 tonnes (five of which have already been contracted with HSL) to ensure logistics sustainment for long-duration deployments. Together, these vessels signal a Navy preparing to operate carrier battle groups in extended theatres.
Tech Snapshot: Surface Combatants
| Platform | Specs / Role | Quantity |
| Destroyers & Frigates | Advanced radar, VLS, integrated EW | 5–10 |
| Corvettes | Littoral/escort missions | 7 |
| Fleet Support Ships | 44,000 tonnes; replenishment at sea | ≥5 (five contracted) |
Submarines and Underwater Autonomy
Submarine warfare remains a cornerstone of maritime strategy. TPCR-2025 highlights two key areas of technology transition.
First, the Navy is exploring lithium-ion battery systems for submarines. These promise longer underwater endurance and quieter operations compared to conventional diesel-electric batteries. Japan has already inducted such submarines (Oryu and Toryu of the Sōryū class, and the Taigei class), and India’s move in this direction represents a significant stealth and endurance leap.
Second, the roadmap calls for 20 High-Endurance Autonomous Underwater Vehicles (HE-AUVs) to support anti-submarine warfare, mine countermeasures, and reconnaissance. These unmanned systems extend the Navy’s reach into the underwater domain, reducing risks to manned submarines and opening new options for distributed operations.
Tech Snapshot: Sub-Surface Fleet
| System | Features | Quantity | Significance |
| Lithium-Ion Submarines | Enhanced endurance & stealth | Planned upgrades | Tech leap beyond diesel-electric |
| High-Endurance AUVs | Unmanned, multi-role (ASW, MCM, ISR) | 20 units | Expands underwater domain awareness |
Unmanned Systems at Sea
Beyond AUVs, the Navy is also studying the integration of unmanned surface and aerial systems. Carrier decks will likely operate UCAVs, extending strike and ISR range. Surface vessels could deploy unmanned boats for surveillance or mine countermeasures. TPCR also includes an unmanned MCM suite (CASCADE ASVs, AUVs, ROVs) to complement manned MCMVs. These trends mirror global developments from US Navy unmanned surface ships to Chinese drone motherships.
For India, unmanned systems reduce risk to personnel, extend surveillance, and create cost-effective mass in high-threat environments.
Beyond Platforms: Future Naval Tech
While nuclear carriers, submarines, and unmanned fleets dominate attention, TPCR-2025 also highlights several supporting technologies critical to survivability and force effectiveness.
- Directed Energy Weapons (DEWs): Cross-service interest in tactical lasers and electromagnetic systems as part of layered defence.
- Airborne Early Warning (AEW) Integration: EMALS will enable fixed-wing AEW aircraft, extending radar coverage hundreds of kilometres.
- Countermeasure Systems: Advanced decoys, chaff, and jammers to shield ships from missiles.
- Networking & ISR: Secure SATCOM, integrated combat systems, and AI-enabled data fusion to ensure carrier groups fight as one connected organism.
Indigenous Drive and Industrial Impact
As with the Army, TPCR-2025 places indigenisation at the centre of naval modernisation. Opportunities span:
- Propulsion: Nuclear reactors, marine gas turbines.
- Energy Storage: Lithium-ion and advanced battery systems.
- Aerospace: TEDBF, deck helicopters, UCAVs.
- Automation & AI: Unmanned autonomy, predictive maintenance.
- Shipbuilding: Destroyers, frigates, corvettes, FSS.
Frameworks like iDEX, TDF, and Make are critical. The Navy will need outreach to bring private industry and MSMEs into these specialised fields.
Conclusion: The Tech-Driven Fleet
TPCR-2025 makes it clear: the future of the Indian Navy is anchored in technology leadership. Nuclear propulsion, EMALS, lithium-ion batteries, AUVs, and indigenous aviation are not isolated projects but part of a coherent vision for a self-reliant, globally relevant force.
The carrier may be the flag bearer of the future navy, but the Navy’s true strength lies in the teaming of surface combatants with advanced weapons and sensors, stealth submarines with next-gen batteries, autonomous underwater scouts, and indigenous fighters flying supported by an intelligent ISR network of networks integrated not only with the Navy but with the other two services. By betting on indigeneous, innovative and intelligent systems, the Navy is on the pathway to a larger role as the sheet anchor of maritime security, stability and safety of the MAHASAGAR.
