Re: India selects Typhoon and Rafale for MMRCA shortlist

A small diameter radar doesn't necessarily make Rafael inferior to Eurofighter. The radar is one of the biggest contributors to frontal radar cross section, and a mechanically scanned radar has a particularly large radar return - AESA is much better in this respect. Smaller radar and AESA means smal...

Cost is probably the main issue - although the Hawk is also very costly. Programmability of handling means it can mimic any other IAF fast jet.
