This hubris will be the downfall of the likes of you. "You don't pay much heed to them". IAF is much smarter than you or the likes of you who takes Pakistan capabilities for granted. There is a reason there was no retalition after 27 February. All that Brahmos Retaliation on 28th FEB ? Once India detected Pakistan is going to fire it's own missiles, they backed down.
You got no proof. Literally no proof and making claims that are way way too childish. Do you know America do regular inventory check on Harpoon Anti Ship Missiles ? And hence a zero percent chance of stealing anything from Harpoon?
Cruise missile biggest advantage is by the time they are detected they are unstoppable. Take an example of Saudi Air-defense. Were they able to detect rudimentary cruise missiles or drones which were launched from 1000 KM range ? Look how precisely they struck
And here we are talking about a much more advanced Babur-2 cruise missile and Ra'ad Cruise missile which are using Beidou Navigation (Link can be provided to show Chinese are providing military grade Beidou to Pakistan since 2014-15) when flying under the radar at heigh of 300-400 Meter. Tell me how can your radar detects the lauch so early that can give them ample reaction time which is already very low because of Babur-2 is gonna be fired from scoot and shoot TEL. I guess you have seen the Pakistani Babur canister TEL which can fire 3 Cruise missiles and then can change its location quickly.
Point being, Has Indian defence forces has ever practice or simulated with these scenarios which Pakistan going to launch at them? If sub-sonic Missiles were useless, Indians wouldnt be pursuing their own Sub sonic missile program. Mind you
Pakistan is making Babur and Ra'ad since 10-12 years. They must have them in numbers that they are confident to launch at India in considerable numbers.
Plus. Pakistan only launched 2 H-4 from Mirages. 4 MK-83 REK from 2 JF-17. Mate I don't know where you getting your news that H-4 was shot down by your AD and one fell near LOC. These are imaginary news mate, which you have no pictures or credible sources to back it up.
Plus F-16 didn't take part in offensive action. They were only doing BARCAP. Hence once again, you need to really revisit your knowledge gaps of what Pakistan did on 27 FEB. No F-16 were lost. Only India claims so. A claim nobody believes
Now coming back to Reaction times of Brahmos and its tree hugging capability. Do you think Pakistani cruise missiles doesnt have these capabailites? I can show you the video of their ALCM travelling at Tree hugging height and you think Indian airforce would be able to detect a tree hugging cruise missile launched during night, on time and would be able to shoot it down?
Remind me what happened to tomahawk cruise missiles which were fired in Syria and Russian Air defense werent able to bring them down ?
Or why Americans doesnt have Super sonic cruise missiles? Why they insist on making sub sonic then if they are so easy to shoot down ?
Coming back to Counter measures against Brahmos. There are none. Zilch. Pakistan is screwed once Brahmos is launched. Why Do you think India backed down from Brahmos retaliatory launc on the 28th FEB? Pakistan was ready to respond with its own Ballistic and cruise missiles because they knew they wont be able to stop Brahmos.
Once Brahmos is launched. A sub-nuclear threshold will be reached and Pakistan will respond with its own Ballistic and cruise missiles. Simple as that.
P.S. There is a reason Pakistna is using TEL for it's BM and CM. You can hit Brahmos with probable missile sites but you can't destroy TEL which are hidden in the underground tunnels of KPK and Balochistan or Sindh. Brahmos cant travel far to Balochistan or KPK. Plus You cant destroy Entire Pakistan missile Infrastructure with first wave of Brahmose missile Strike
Also You cant strike nuclear installations. There is a pact b/w india and Pakistan where both countries share the Nuke installation location regularly so they can't attack each other installations.
