Overview of Project 75I and where the deal stands
Project 75I is India’s planned acquisition program to add next-generation conventional submarines to the Indian Navy. The program aims to combine foreign designs and technology with local shipbuilding and systems integration.
Recent reporting indicates the procurement process is in advanced stages, with government approvals and industry negotiations nearing finalization. This article explains what the deal will likely cover, practical steps ahead, and lessons from past projects.
What Project 75I will deliver
The core objective is to induct six modern conventional submarines with enhanced endurance, stealth and sensor suites. Project 75I is intended to upgrade India’s undersea deterrent and form a bridge to future capabilities.
Expected or typical features of submarines under this program include:
- Air-independent propulsion (AIP) for longer underwater endurance
- Advanced sonar and electronic warfare systems
- Improved acoustic quieting and reduced detectability
- Integrated combat management systems with data links
- Local manufacture and systems integration with technology transfer
How the contract process works for Project 75I
Large defense contracts follow a standard sequence of steps. For Project 75I these typically include technical evaluation, commercial negotiations, government approvals and detailed design work.
Key contractual elements to watch for are:
- Scope of technology transfer and offsets to Indian industry
- Delivery schedule and penalties for delay
- Support packages: training, spares, and in-service support
- Intellectual property terms and local content thresholds
Procurement timeline highlights
Timelines will vary by vendor and negotiation complexity. Typical milestones include contract signing, detailed design review, keel laying, sea trials and handover.
Planning for logistics and infrastructure upgrades at shipyards and naval bases will run alongside production to ensure timely commissioning.
Industry and strategic implications
Project 75I impacts multiple stakeholders: foreign OEMs, Indian shipyards, defence suppliers and the Navy. A successful deal boosts domestic shipbuilding capability and supports supplier ecosystems.
Strategically, these submarines will strengthen India’s ability to patrol key sea lanes and deter potential adversaries in the Indian Ocean region.
What domestic industry gains
Local yards and tier-1 suppliers will benefit from sustained workload, skill upgrades and export opportunities. The program’s technology-transfer clauses are central to long-term capability building.
Risks and practical challenges to manage
Large submarine programs carry well-known risks: schedule slips, cost escalation and integration complexity. Clear contractual terms and robust project management reduce these risks.
Practical measures to manage risk include:
- Staged payments tied to milestones and verified progress
- Independent technical reviews during detailed design and construction
- Defined acceptance tests and performance criteria prior to handover
- Continuous training pipeline for shipyard workers and naval crews
Case study: Lessons from Project 75 (Scorpene)
Project 75, which produced the Kalvari-class submarines, highlights useful lessons. The program involved a foreign design licensed for local construction with technology transfer obligations.
Key takeaways from that project include the importance of realistic timelines, strong quality controls, and early planning for logistics and training. These lessons are directly applicable to Project 75I.
What to expect after deal finalization
Once the contract is signed, expect an immediate move to detailed design and infrastructure upgrades. Shipyards will recruit and train workers, while the Navy will prepare crew training programs.
Authorities typically publish periodic progress reports or defense ministry updates. Watch for announcements on keel laying and first-of-class trials as milestone indicators.
Practical checklist for stakeholders
- Confirm milestone definitions and verification processes.
- Ensure spares and support timelines are defined for first five years.
- Map supply chain readiness for key subsystems like AIP modules and combat systems.
- Plan for sustained workforce development and knowledge transfer.
Project 75I aims to combine foreign submarine technology with Indian construction and systems integration to build six advanced conventional submarines for the Indian Navy.
Small real-world example: Managing a submarine milestone
When a shipyard prepares for keel laying, practical coordination covers materials, workforce and quality checks. One yard set up a daily review team that included procurement, quality and naval representatives.
That team solved supply bottlenecks within weeks and avoided a three-month delay by re-sequencing non-critical work. This example shows how focused cross-functional teams help keep complex projects on track.
Conclusion: Practical steps to monitor progress
As Project 75I nears a deal, stakeholders should track contract clarity on technology transfer, delivery milestones and in-service support. Strong project governance and early workforce planning will determine success.
For readers following the program, focus on milestone announcements (contract signing, keel laying, trials) and government updates for the most reliable indicators of progress.
Further reading and actions
- Follow official defense ministry releases for confirmed milestones.
- Monitor shipyard procurement notices and tender documents for subcontracting opportunities.
- Read technical briefings on AIP and submarine acoustic signature management to understand capability trade-offs.
