I think we need to start developing mobile SRBM system like 9K720 Iskander or LORA system on our own along with different type of Cruise missiles i mentioned few post back. Long range accurate safe engagement is the way forward. SCALP & Brahmos performance has been exceptionally well. Speed & stealth combo took Porkee airbases completely by surprise now imagine a conventional Quasi ballistic missile with both the characteristics.
No one know Astra MK2 true range but we now know what's PL 15 true range is so stop coping nothing special about Chong missiles.I strongly think the bats have given them the real deal PL15 which does outgun our Astra Mk2. And its likely been datalinked with their AWACS for guidance.
