Where's the expert analysis about choice of S-400 by India?
I never knew @RANDCorporation came out with such absolutely nothing blogs!
Lets see where India stands on points raised by him -
(1) Combined Air Picture: IAF operates a robust Integrated Air Command and Control System (IACCS) which merges inputs from all available radar sources to build the big radar picture of air-space. #radars

A S-400 regiment will know about the air-threats (air-craft or missiles or cruise missile) irrespective of what its own radar picks-up.
(2) Radar Horizon: IAF operates multiple types of radars. These are -
(a) High Power Radar [THD-1955 ]
#radars
- Range > 1,000 km.
- Imported (initial units) & DRDO radars (1st picture) to replace older ones

(b) Medium Power Radar (MPR):
- Mix of Israeli (EL/M-2084, 2nd pic) and DRDO radar (3rd pic)
- 4D AESA radar with range > 300 km.
- Both Israeli & DRDO radars are called Arudhara Diagram of DRDO High Power Radar complex
(c) Lowe Level Transportable Radar (LLTR):
- These are gap fillers which provide coverage in difficult terrains where MPR might get masked.
- 32 imported unit from Thales (GS-100)
- 30+ DRDO Ashwini LLTR
- Total requirement - 67

(d) Aerostat Radar
- IAF got couple of systems from Israel (EL/M-2083)

- DRDO working on domestic alternative.
(e) AWACS:
- Phalcon AWACS (3 units)
- Netra AEW&C (2 units)
(f) Ballistic Missile Defense (BMD) Radar - Swordfish
- Mother of all radars
- Indian derivative of Israeli Green Pine radar (EL/M-2080) which forms part of its Arrow BMD system.
Conclusion:
- IAF employs a range of radars to track airspace.
- All this data is fused together at IACCS nodes and distributed to concerned entities.
- And as more radars enter service, the coverage will become still more expansive.
- S-400 won't work as a stand-alone system
