HAL to build 8, then 12, Tejas fighters each year | Business Standard News
The ministry of defence (MoD) has sanctioned Rs 1,556 crore for HAL's high-tech production line that aims to build 12 Tejas fighters each year. The funds will come from the IAF (25 per cent); the navy (25 per cent), while HAL will put up half the money.
Business Standard visited the new Tejas production line, an expansive 28,000-square metre facility in four massive hangars in HAL, Bangalore. Work is already underway on the first IAF order of 20 Tejas Mark I fighters, with an order for 20 more in the pipeline once the aircraft gets "final operational clearance" next year. The first two fighters being "series produced" - they are numbered SP-1 and SP-2 - are visibly taking shape.
