3 forces are driving growth in India's defence sector: government spending, indigenisation, and export demand.
India’s 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.
📍Corporate India reported that over the three years to June 10, 2026, the stock returned 631%, while its market capitalisation rose from ₹1,540 crore to ₹15,923.61 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 India’s defence opportunity is spreading.
📍India’s FY27 defence budget is ₹7.85 lakh crore, and of the ₹1.85 lakh crore capital-acquisition budget, 75% is earmarked for domestic industry.
📍Defence exports also reached a record ₹38,424 crore in FY26, up 62.66% from the previous year.
That spending travels far beyond the final platform.
→ Training and simulation
→ Counter-drone systems
→ Surveillance and electronics
→ 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.
India’s 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?
