About Mazagon Dock Shipbuilders Limited (MDL)

Mazagon Dock Shipbuilders Limited (MDL) is India’s leading naval shipyard with a lineage dating back to 1774, marking over 250 years of maritime engineering excellence. It was incorporated as a private limited company in 1934, acquired by the Government of India in 1960, delivered its first frigate (INS Nilgiri) in 1972, began building submarines in 1984, commissioned the first Indian-built submarine (INS Shalki) in 1992, and commissioned the first destroyer (INS Delhi) in 1997. The company was awarded Mini Ratna Category-I status in 2006 and listed on BSE and NSE in 2020; in 2024, it earned the prestigious Navratna status, the first government-owned shipyard and only the third Defence PSU to do so. 

MDL celebrated its 250-year legacy in May 2024, including the release of a commemorative Rs 250 coin, and expanded its industrial footprint with the acquisition of Mumbai Port Authority land for long-term infrastructure growth. These milestones reflect MDL’s central role in India’s naval modernisation and shipbuilding capability.
