Even within competing AESA radars, there is a difference in
capability.
In the context of the IAF, imho, the F-16IN actually
most suits the IAF and will win it hands-down in a
non-political field.
The IAF requires a cheap fighter to partner the sukhoi. That
already rules out the competitors except the gripen. In terms of
capability, the AESA equipped F-16IN exceeds the capability of the
gripen.
The typhoon, rafale, super hornet can make an argument
for efficiency in that in terms of per aircraft basis, it can
out-perform the F-16IN. However, all fail in the
primary consideration of the IAF in that the IAF is gunning to
maintain or increase the no of sqns. Cost wise, the 3 cannot be
procured in the numbers that can justify the sqn nos esp when
factoring in maintenance, munitions and airplane cost.
The Mig-35 suffers from serviceability issues and being
twin-engined like the super hornet will ensure that
maintenance cost is significantly higher.
Factoring in the other positives, eg training, as a lead in
fighter to the F-35, something which I mentioned before LM put
in to its marketing brochures, the access to the far
cheaper range of munitions offered by the USAF eg SDB, JSOW,
SFW (already in IAF service), Harpoons, AIM-120D (future), paveways
etc, makes the F-16IN a superior choice. The end of the F-16 line
will also allow better bargaining in terms of cost and oppotunities
for Indian industry participation.
Besides AESA, SDB in particular should be a big,
big plus for the F-16IN.
The defensive suites of the Typhoon, Rafale and Super Hornets
are probably superior esp in terms of integration into the airframe
but the suites available to the F-16IN does mitigate this
somewhat.
The biggest hurdles has been that Pakistan has F-16s and US
restriction on arms use including the threat of embargo. The
earlier is actually deceptive cos there are already more than
enough suks to over-kill the PAF and the F-16INs are actually
primed to tackle the threat of the PLAAF esp when considering the
airbasing restrictions for the PLAAF in Tibet. The latter ie
embargo can be managed with the huge supply of spares from
operators around the world and serviceability plants set up in
India.
Imho, it makes sense for the F-16IN selection, if properly
handled.
