Thank you, first of all, in posting many images that are presumably from the Expo.
Can you clarify what exactly are the roles of ADA and HAL.
It was my understanding that ADA designed fighter jets and aircrafts while HAL manufactured them. It also makes sense that HAL has an in house design and development department - ARDC .
Also, ADA is a subsidiary of DRDO.
Going through the wiki- entries of all these fighter jet programs
Tejas Mark 2 - DRDO ( design)
TEDBF - HAL ( design)
AMCA - HAL + DRDO ( joint design + production with a private company )
Ghatak - DRDO
Is there a competition between HAL and DRDO ?
Why does India need a private company to produce AMCA ? Why when no private company with atleast some experience in producing even military drones exist ( like Baykar of Turkey). This is a weird choice but thats a question for later.
