The deal involves building six advanced conventional submarines in India by Mazagon Dock Shipbuilders in collaboration with Thyssenkrupp Marine Systems. The contract includes full transfer of design and technology, making it one of India’s largest defence procurements. The submarines will feature air-independent propulsion systems, enabling longer underwater endurance and enhanced stealth. They are expected to modernise India’s ageing fleet and strengthen naval readiness in the Indian Ocean region.

The submarines, based on HDW Class 214 variants, will bolster India’s maritime security amid growing regional competition. The first delivery is anticipated seven years after contract signing. Singh’s visit highlights India’s push for self-reliance in defence manufacturing under the Make-in-India initiative while deepening Indo-German strategic ties.
