3 forces are driving growth in India's defence sector: government spending, indigenisation, and export demand.
Indiaβs defence winners now extend far beyond companies that manufacture aircraft, ships, and missiles.
Zen Technologies Limited built its business around military training and simulation systems.
πCorporate India reported that over the three years to June 10, 2026, the stock returned 631%, while its market capitalisation rose from βΉ1,540 crore to βΉ15,923.61 crore.
During early 2026, the Sensex and Nifty were both falling from recent highs.
The stock chart is striking, but the business underneath tells us more about where Indiaβs defence opportunity is spreading.
πIndiaβs FY27 defence budget is βΉ7.85 lakh crore, and of the βΉ1.85 lakh crore capital-acquisition budget, 75% is earmarked for domestic industry.
πDefence exports also reached a record βΉ38,424 crore in FY26, up 62.66% from the previous year.
That spending travels far beyond the final platform.
β Training and simulation
β Counter-drone systems
β Surveillance and electronics
β Testing and combat-readiness tools
Every new platform creates an ecosystem around it.
More aircraft need trained crews, and more drones create demand for counter-drone technology; more indigenous procurement creates room for specialized
Indian suppliers that were once too small to notice.
Zen is a useful example of that shift.
Indiaβs defence story is becoming much wider than the names people traditionally associate with the sector.
Which part of the defence value chain do you think the market still underestimates?
