🚨India is scaling up its underwater fleet by expanding its Phase 1 conventional submarine plan from six to nine hulls to secure the Indian Ocean Region.
🚢 Project 75I: The first six diesel-electric attack submarines will be built by Mazagon Dock Shipbuilders Limited in collaboration with Germany’s TKMS. They will feature advanced Air Independent Propulsion systems, allowing them to remain submerged for weeks without resurfacing.
⚓ The Extra Three: An additional order of three conventional hulls will follow immediately to maintain a warm assembly line and quickly bolster numbers.
🇮🇳 Indigenous Growth: The project mandates domestic sourcing, aiming to transition from 45% local content to 60% by the sixth vessel, paving the way for the fully indigenous Project 76.
⚠️ The Catalyst: Naval planners expanded the order to counter looming fleet attrition as older Russian and German hulls retire.
It also directly addresses regional challenges, including China’s massive submarine expansion and Pakistan’s upcoming acquisition of eight Hangor-class vessels.
