Critically evaluate the lead–follow shipyard model and public–private partnerships in meeting the Indian Navy's force-level targets.

In the lead–follow model, one shipyard designs and builds the first ships of a class. A second yard builds more ships of the same design at the same time. The Navy's 11 Next Generation Offshore Patrol Vessels (NGOPVs) follow this model: Goa Shipyard (GSL, lead) builds 7 and GRSE (follow) builds 4, worth ₹9,781 crore under Buy (Indian-IDDM) [1][2]. The programme shows that the model speeds up construction, but timely delivery is a separate test.

Strengths

• Two production lines: yards on both seaboards build at once. GRSE launched its fourth and last hull, Shreyas, on 10 October 2026 [4].
• One design for both yards: GSL handles the design [2]. The follow yard avoids repeating design work, and both yards' ships share common spares and training.
• Private yards add capacity: GSL had the main hull blocks of Yards 1281–82 fabricated at private Yeoman Marine, Ratnagiri [3]. This frees space at public sector yards and grows the private supplier base.
• Aatmanirbharta: the IDDM category keeps design know-how and spending in India [1].

Weaknesses

• Both yards depend on one design: CAG Report No. 32 of 2010 traced warship delays to late structural drawings, steel shortages and weak infrastructure at public sector shipyards [5]. Under lead–follow, late drawings at the lead yard stall both yards.
• Launch is not delivery: deliveries were due to start in September 2026 [1]. Yet as of October 2026, only launches have been reported [4]. A launched hull still needs fitting-out and sea trials.
• Private-yard risk: ONGC ordered 12 vessels from Pipavav Shipyard for delivery by December 2011. Only 7 had arrived by March 2018, and the contract was ended in July 2018 [6].
• Cost to force levels: CAG Report No. 7 of 2011 found Coast Guard vessels kept on extended service because their replacements were late [7]. Late OPVs likewise keep ageing ships on patrol.

Verdict and way forward

• Fix the final design at the lead yard before hull work speeds up.
• Link payments to private subcontractors to stage-wise progress checks.
• Publish planned and actual delivery dates, not just launches.

Overall, the lead–follow model and public–private partnerships are sound ways to raise naval force levels, but they only work if the design is final and progress is closely monitored. With these safeguards, they can deliver ships on time while serving the goals of Aatmanirbhar Bharat and India's role as first responder in the Indian Ocean.
