2nd crew-member egress?
It's often non-obvious, non-aero things: for the F-16, the redesign from the prototype tanks was motivated by the
damage to the tank from the cannon fire blast wave.

The primary problem was a significant issue with loads/structures unrelated to the gun.

That doc does not address it but there were unanticipated loads issues with the first design, and thus the design necessarily evolved as a consequence. As it evolved, gun issues emerged — as outlined in your reference.

Of course, the F-16's and 18's CFT's came many years (decades) later..

How/where did you hear about those results in Indian trials?? Curious..
