The test pilots gave a display of modern avionics at the HAL grounds here and demonstrated the ability of Tejas to fire missiles with helmet-mounted display system.
Officials said HAL plans to initially produce eight LCAs every year and then scale up production to 16.
Tejas can fly 1,700 km non-stop and has "glass cockpit display system".
K. Tamil Mani, director general at the Aeronautical Systems of DRDO, told IANS Thursday that "the aircraft is 65 percent indigenous". He said the engine, ejection seat and radar are among the components that have been imported.
Officials estimate the development cost of the Tejas to be around 10,000 crore.
Antony said IOC-II of Tejas was a significant milestone in indigisation through self-reliance.
"We can declare we are nearing success. We have passed the semi-final," he said.
The minister said India can make world class fighter aircraft, warship and tanks.
He called for major breakthrough in the next five years in all areas in which India was lagging behind.
