Hawk-I isn’t Combat Hawk, Hawk I is HAL’s MLU of EXISTING Hawk Mk.132s, they have added some new avionics and updated the cockpit. Combat Hawk was to be a NEW BUILD modified version of the Hawk with an enhanced engine and weapons/sensor capability.
Advanced Hawk is something different still. It is a new build enchanced TRAINER that can simulate 5th gen fighter cockpits and systems.
Hawk-I is the only one of these that is a reality, the number of Hawks has not increased, IAF only want it for trainer roles.
That Heron had nothing to do with this EX, it was undertaking regular surveillance ops.
Hawks are not air superiority fighters but are for CAS roles. They can be armed with Helina/SANT missiles and even loaded with cannons and cluster bombs for CAS roles.
The Hawk-i is meant to be made in India fully with the indigenous engine HTFE25. Till now, the plane was made in India but engine was imported from UK. But, going forward, Hawk-i will be fully Indian. Modern warfare is almost completely dependent on aerial ability and the number of aircrafts required will be huge. Hawk is a relatively simple plane with simple parts and avionics and hence easier to assemble, it will always be attractive to mass manufacture hawks for war in thousands just like cars are made (India makes over 12000 cars a day, FYI)
Apart from the mere approval for the Pan India exercise its also the cost factors i am sure this exercise alone would have costed the exchequer 1000s of crores if not in 100s i mean the operational expense ..I May be wrong tooo with the numbers ..Which also brings to my mind another question..When a time the govt said it don t have much money for defence modernisation why did they given approval for such large scale exercise ..if 100 crores is there they could have equipped another 30000 soldiers with the lastest BPJ they had ordered ...
Even BPJ is a short term investment. The BPJ gets worn out in 2 years under regular wear and tear. The gagan-shakti is not just a show but assessment of tactics and weapons. India has got several new weapons like Garuda, Garuthmaa bombs, Brahmos missiles, SAAW, cluster munitions, thermobaric bombs and new electronics like LGB, EW and newer planes like Tejas. These kind of exercises is to know how to coordinate the various types of planes, to get feedback on the abilities and effects of various planes and munitions on the tactics and so on.
These kind of tactics have to be done regularly, may be once a year so as to fine tune the tactics and achieve perfect coordination amongst all the pilots, logistical departments and to find the best possible combinations of tactics across various terrains and scenarios. All this must be noted down and an extensive debate must be held for the same
