New Delhi: The Indian Navy unified submarine architecture plan is set to transform India’s underwater defence capability. In a major move, the Navy is planning a common design framework for Project-76 and Project-77 submarines to increase indigenous content and reduce dependency on foreign systems.
This step aligns with India’s long-term goal of self-reliance in defence manufacturing under the government’s “Make in India” initiative.
What Is the Indian Navy Unified Submarine Architecture
- The Indian Navy plans a common design structure for future submarines.
- This will be used in both Project-76 (conventional submarines) and Project-77 (advanced submarines).
- Aim:
- Increase indigenous technology
- Reduce cost and development time
- Improve maintenance and upgrades

What is Project-76 Submarine
- Project-76 is focused on next-generation conventional submarines.
- These submarines will likely include:
- Advanced stealth features
- Indigenous combat systems
- Air Independent Propulsion (AIP) technology
- It will follow the current Kalvari-class submarine program.
What is Project-77 Submarine
- Project-77 is expected to be a more advanced and futuristic submarine program.
- Likely features:
- Land-attack capabilities
- Better endurance and stealth
- High level of indigenous systems
- It may include technologies beyond traditional diesel-electric submarines.
Why Indian Navy Unified Submarine Architecture Matters
- Common systems across submarines reduce duplication
- Easier training and logistics
- Faster production cycles
- Better interoperability between fleets
This approach is similar to global naval strategies where standardization improves efficiency.
Focus on Indigenous Content
The Indian Navy aims to significantly increase local manufacturing and technology development:
- Use of Indian-made sensors and weapons
- Boost to domestic defence companies
- Reduced reliance on imports
- Support for Atmanirbhar Bharat (self-reliant India)
Strategic Importance for India
- Strengthens India’s position in the Indian Ocean Region (IOR)
- Enhances underwater deterrence capability
- Helps counter growing submarine presence of rival nations
- Supports long-term naval modernization plans
Government and Defence Push
- The plan is aligned with policies from the
- Supports initiatives like:
- “Make in India”
- Defence indigenisation roadmap
- Encourages private sector participation
