The Indian Navy has expressed significant concerns regarding TKMS’s proposal for the Project-75I submarine program, primarily due to its untested angular hull design aimed at enhancing stealth. Despite TKMS’s established reputation with proven submarine models, this new design poses risks of developmental delays and reliability issues, with a possible delivery timeline for the first submarine extending to 2034. Given the declining numbers of India’s aging submarine fleet, timely implementation of Project-75I is crucial for maintaining maritime security amidst regional threats from China and Pakistan. The Navy’s cautious stance underscores the importance of balancing innovative designs with proven operational reliability in defense procurement.
