The Defence Acquisition Council has given approval for procurement of 83 indigenous Tejas fighter aircraft for Indian Air Force. The Light Combat Aircraft Tejas indigenously-designed by Aircraft Development Agency under the Defence Research and Development Organisation and manufactured by Hindustan Aeronautics Limited is going to be the backbone of Indian Air Force in future. While orders of 40 Tejas aircraft had been placed with HAL in initial configurations, DAC paved the way for procurement of another 83 of the more advanced version of the aircraft from HAL. This procurement will be a major boost to Make in India as the aircraft is indigenously designed. The Defence Acquisition Council also accorded approval for acquisition of indigenous Defence equipment for about 171 million dollars. The deal with Hindustan Aeronautics Limited also includes maintenance and infrastructure. Initially, HAL quoted nearly 7.9bn dollars but the contract price has now decreased to a final amount of up to 5.4bn dollars. Under the deal, the Mark-1A jets will feature 43 improvements. The Mark-1A fighter jets are expected to be delivered three years after the agreement has been signed.
