India and Germany are nearing an 8 billion defense agreement for the construction of six stealth submarines, potentially the largest defense deal New Delhi has ever signed. The pact, expected to be finalized during German Chancellor Friedrich Merz's upcoming visit, includes technology transfer for submarine production in India by Thyssenkrupp Marine Systems and Mazagon Dock Shipbuilders. This deal could lead India to reconsider acquiring additional submarines from France and signifies a deepening defense partnership, with discussions also covering co-development and co-production of defense equipment.
