What L&T SHIPBUILDING LIMITED does

L&T Shipbuilding Limited is a privately held Indian shipbuilder and a subsidiary of Larsen & Toubro Limited, headquartered at the Kattupalli shipyard near Chennai with a registered office in Mumbai. The company designs, builds, and maintains defence and commercial vessels and marine platforms, including patrol craft, warships, LPG/LNG carriers, chemical tankers, and heavy-lift vessels, using modular construction technology, in-house floating dock design, and 3D-modelled engineering workflows. Its core customer base is the Indian Navy and Indian Coast Guard, to which it has delivered more than 65 defence vessels in less than a decade under Make-in-India-aligned procurement programmes.

The business operates two primary revenue streams: defence vessel newbuilds and commercial vessel newbuilds, both executed on a project basis, supplemented by ship repair and refit services leveraging the yard's in-house floating dock. A technical collaboration with Mitsubishi Heavy Industries (Japan) underpins ship design and engineering, and additional European and Asian design partners are engaged for specialised programmes. Geographically, the company has extended its commercial order reach into Europe, the Middle East, and Southeast Asia, reducing — though not eliminating — dependence on Indian government tenders. The firm does not disclose standalone revenue, and its financials are consolidated within L&T's defence and heavy engineering reporting segments.
