India is now set to give preliminary approval to three mega indigenous projects to manufacture another aircraft carrier, 97 more Tejas fighters and 156 Prachand light combat helicopters, which together will be worth around Rs 1.4 lakh crore. The Rajnath Singh-led defence acquisitions council is likely to take up the ‘acceptance of necessity’ (AoN) — the first step in the procurement process — for the three crucial projects at a meeting slated on November 30, sources told TOI on Thursday.
