This, right here, is the heart of the problem. F*#kin defensive mindset of PAF man, now tell me how many jets did these sams shoot down......
What i'd say here is, AD does have its utility in our theatre. Indian AD performed exceptionally well. Pak AD was not bad either, but there was alot left to be desired.
I dont necessarily agree with the procurement decisions made at the moment, i might even dare to say they reek of corruption and under the table bribes etc, but whatever. The issue isnt in the systems, rather, the fact that the systems we've been buying havent been well suited to our threats. This, i addressed heavily in an episode of the Quwa Podcast.
These shiny missile systems will turn into useless white elephants very soon, mark my words, mainly because missile based air defenses are getting outdated in face of high speed missiles very quickly.
Again, not necessarily true, AD has been performing exceptionally well in ukraine, israel, ME etc. But if you're expecting the Iron dome to take down hypersonics, yea, in that case your expectations, not procurement choices need to be adjusted.
A SAM does not have enough energy to chase after high speed high maneuvering targets as it rises against gravity.
Again, its really a case of 'it depends'.
We're seeing alot of long range sams go the way of a huge booster and a smaller dart. This gives you far superior energy in the terminal stages, Though, im sure this design is just easier to produce, and cheaper, hence its popularity! Very good design choice though IMO.
Focus is shifting worldwide to electronic kill or laser based defences. Only air to air missiles, launched from high altitude having the necessary energy can really chase the targets to destruction now.....
Lasers, or Softkill systems arent going to be able to destroy every type of target, nor will AAM's.
One aspect you forget about is the complication AD adds to adversary mission planning.
The IAF needs to factor every missile into its plans of attack. The pilots need to keep in mind that at any point, they could be fired upon etc. This in itself creates a barrier, but also, makes adversary missions more complex.
The wrong type of ad, such as FD2000s layered with HQ-9s?! (see where it feels a bit shady), alongside HQ-16FE's? The wrong type of AD like this, will probably be a detriment.
However, a proper layered defensive system, built off of modern, agile missiles will be a great asset to the PAF and the country. Unfortunately AD is a very long term purchase, so we've made our bed now, and must lay in it.
And to your first point, i agree, we must shift to an offensive defense type doctrine, but we can discuss that elsewhere. Happy to make my post more detailed and discuss in depth elsewhere too. Mods will throw a hissy fit and close this thread if i ramble on too long and others carry the discussion on too far here.
