The aerospace and defense sector in Maharashtra is characterized by large, diversified conglomerates and specialized engineering firms. Companies such as Tata Group and Mahindra Group, with over a million and 237,000 employees respectively, operate across numerous industries globally, including defense. Larsen & Toubro is a multinational specializing in engineering and hi-tech manufacturing, while JSW is a $23 billion conglomerate in steel, energy, and infrastructure, with global operations.
A notable pattern among these companies is their concentration in Mumbai, which serves as the headquarters for most of the major players, including Godrej & Boyce Mfg. Co. Ltd., a brand involved in precision manufacturing and aerospace, and Hindalco Industries Limited, a global metals company. This centralizes a significant portion of India's aerospace and defense industrial base within the state's capital.

How this list is built
Every company on this list has a Tamtam company profile. The industry is the one the company gives on LinkedIn; categories such as SaaS or fintech are classified by Tamtam's AI from the company's website and LinkedIn page; and the headquarters city must match the company's own address. Companies are ranked by the number of employees on LinkedIn, and the list is refreshed every night. Classifications can be wrong, so treat the list as a starting point rather than an official ranking. Last updated Nov 15, 2026.
