But I am little surprised that JF-17 scoots everytime that the LCA enters the frame. Yes, there is a qualitative difference in both the aircraft, but the JF-17 has a completely nonwestern systems dependency-line. That is a selling point for many countries!

In the year 2019, they are trying to deliver 12 more aircraft.

It is a tough ask, but that is their target. For that to happen, both lines have to produce aircraft at one per 1.5 months (8 per year).

But, I have hope. They beat the March 31 target for all IOC deliveries.
