your answer is-
diversification of resurces.
.
Now for comperison.
1. present Mki-- bar radar, high rcs(approx-10sqm), not full glass cockpit, k-100 a2a awacs-killer not intigrated, unable to carry brahmos, pesa radar, and Al-31 engine.
.
.
2. Super 30 upgrade-- bar aesa radar, may be Al-41 engine for high power, low rcs by RAM coating application on skin, full glass-cockpit, integration of k-100 a2a and brahmos,
.
These are only few upgrads.
+ HMDS,
+ Not sure if later engine replacment will be inclued but currently plans are purely to modify the AL-31FP, presently rated at
126kN with afterburning, will offer
20% more power when uprated by NPO Saturn-its manufacturer-and will have a total technical service life of
6,000 hours, instead of the present 2,000 hours. The uprated engine will also employ a larger diameter fan, redesigned key hot-end components and cooling system technologies to permit reduced thrust lapse rates with altitude, which in turn will permit
supercruise.
+New-generation full-authority digital engine controls (
FADEC) as well as
all-axis thrust-vectoring nozzles (±15 degrees in the vertical plane and ±8 degrees in the horizontal plane.
+The digital flight-control computer too will be replaced to achieve
harmonisation of the digital flight control laws associated with
supercruise and all-aspect
supermanoeuvrability.
+Hands-on-throttle-and-stick (
HOTAS) controls.
+Mission management avionics package will include
dual redundant core avionics computers developed by the
Defence Research & development Organisation’s (DRDO) Bangalore-based Defence Avionics Research Establishment (DARE) and built by Hindustan Aeronautics Ltd (HAL).
+The
integrated defensive aids suite, now being developed by a joint venture of DARE and Cassidian of Germany, will include the MILDS AN/AAR-60 missile approach warning system (MAWS).
+
EW management computer and
Tarang Mk3 radar warning receiver (developed by
DARE and built by Bharat Electronics Ltd).
+ Countermeasures dispenser built by
Bharat Dynamics Ltd,
+
Expendable active electronic decoys, a reusable fibre-optic ABRL active radar towed-decoy using suppression, deception and seduction techniques, and
an internal EW suite supplied by Elettronica of Italy (the very same Virgilius suite that is on board the
MiG-29UPG and EFT).
+ SO much more in terms of avionics and a kick a$$ weapons package but I'd be here all night if I tried to list them all. It is not hard to see why this plane will rule the skies EASILY of Asia and anywhere there isn't a 5th gen fighter around (and in some cases even when there is!).
