The Chief of Air Staff said the second line of fighter jets will be in addition to light combat aircraft Tejas and 36 Rafale planes that India will procure from France.
"Definitely they (government) are thinking to set up one more line of fighter aircraft in a year under the Make in India project so that the dwindling fighter aircraft fleet can be replaced within shortest possible time," Raha said.
"This plan is going to materialise in a year's time... Addition of new aircraft to the IAF fleet through indigenous technology is also being worked out, with the Hindustan Aeronautics Ltd (HAL) providing 120 LCA," he said.
The IAF chief said the Rafael multi-role fighter plane contract with France was likely to be through soon.

"Rafale contract is likely to be through as a lot of progress has been made. The outcome will be substantial in the first year itself. We are yet to work out modalities. The government is willing to spend more to improve operational capability of the armed forces."
On nearly 10 per cent increase in defence budget estimates
for 2016-17 at Rs 2.58 lakh crore as compared to last fiscal, Raha said more money will help cover inflation, replace and upgrade existing aircraft and related technology, and give a push to acquisition of equipment.
"Technology is fast becoming obsolete and within 15-20 years, any platform faces obsolescence, which needs to be replaced and updated. We are upgrading Miraj 2000, MiG 29 and Jaguar to achieve effective operational capability," he said.
"The committee is going to submit its report by March 31," the IAF chief added.
