You are of course aware that the IL-76 model forms the basis of the Indian strategic transport fleet, the in-flight refueling force and even some ARC aircraft. The supporting infrastructure is tailored around this model. This includes spare parts, runway strength, runway lengths, trained maintenance crews, ground equipment etc.
The IAF also has a good understanding of what the aircraft is able to do and what it cannot do in terms of operating from high altitude airbases to coastal airbases etc, range, endurance and payload capacity etc. This is not as trivial as it may sound.
In view of this, the IL-76 model serves more in terms of logistical nuances and allows quicker integration into the Air Force structure. Sometimes these issues far surpass the cost issue.
Besides the nose mounted system would be more survivable in a war scenario as the Rotodome presents a bigger target than the nose system.
Not sure how you mean the above.
Nevertheless, as far as IR signature, Radar signature and visual signature (measured as size of aircraft) is concerned, the radar mounting hardly affects the overall scheme of things. Not to mention that the in terms of radar coverage without involving aircraft maneuvering is far better in case of the triangular arranged arrays on the radar disc on top of the Indian Phalcon.
Let's not insult the IAF as far as professionalism is concerned, shall we? They are bound to have looked at the issue more than us arm chair generals, right?
