Larsen & Toubro (L&T) has announced significant advancements in India’s indigenous defense capabilities with the development of the SOV-400 midget submarine, designed entirely in-house. This 400-ton submarine enhances India’s covert operational capabilities, particularly for special forces and coastal defense against regional threats. L&T is set to expand this design into 500-ton and 600-ton variants, improving endurance and payload while contributing to the Indian Navy’s future projects. The certification of the SOV-400 by a European firm reinforces its compliance with international standards, positioning it as a competitive alternative in the market. These developments signify a strategic shift in India’s naval defense strategy, emphasizing littoral dominance and the importance of specialized platforms in contemporary maritime security.
