Pakis are acquiring the long range PGM's and MLRS from chinkis.
Yes our bases are 150km from their bases but how much distance from the border line itself?
Cost of SAM's are higher than the iron dome and automated air defence guns.
You can't stop long range MLRS with traditional SAM's, sooner or later you will run out of SAM's and puts everything at risk.
First of all read the content correctly ,i have talking about point defence.
Second stop using smileys.
Akash has already demonstrated ability to shoot down Spice 2000 PGM.
Even MRSAM will be more than capable of doing this then.
Regarding
Already mentioned that our bases are around 100 km from border. ( Amritsar is just 40 km thorough. Ditto for Lahore )
QRSAM can help IAF to get an additional layer of protection for any miss from MRSAM/Akash.
Unlike Israeli situation where it's under attack 24x7x 365 from just across the wall, the western border is more of less a flat desert with good visibility. Difficult to amass MRLS and artillery without UAVs/ Satellites/ spy planes not picking up things, and army not responding immediately. As such our infra is spread out .
Regarding running out of SAMs , Phalanx CRAM has 1500 ammunition , fires at rate of 4500 per minute. Iron dome too has limited missiles like Akash.
Plus the pakis are already facing 3 Brahmos regiments of army and 2 squadrons( or atleast 1) of Brahmos of IAF. add to it Smerch and Pinakas. Mischief along Gujarat and Rajasthan can be spotted easily, but Punjab is difficult as it has highly populated areas( same is applicable for Pakistani Punjab). So response time will be low in Punjab .
Regarding critical infrastructure, QRSAM is being developed. Command Control facilities , Powerplants, dams etc can be. protected by them. The Spyder SAM have been inducted for this reason only , to protect command Control facilities.
