It's a very israeli view. Granted, verified just today(and embraced with success by some customers), but still rather unique in modern world.
Other nations tend to be rather patchy about ALBMs; only Israel made it into a cornerstone of its stand off capability sets.
I think it's a very bad approach to see it as uniquely Israeli (and now Indian) approach.
Ballistic Missile Defense is more expensive and more complex than defeating ABTs.
And ABTs really lost their edge recently. That's why many are investing in creating a hi-lo mix of cruise missiles.
ALBMs are one way of getting the edge back, but with some of the advantages an aircraft provides (e.g. guidance and BDA) and at lower cost per effect than ground launched BMs.
The US is also exploring putting the PrSM on an aircraft, for example.
Unsurprising view, as their AF is the only properly developed branch.
The only branch of the IDF I'd say is under-developed is the navy, but one look at the geography and you'll see why.
The IAF is the only branch that's really professional, but it's a pretty universal thing that you can only create pockets of excellence in an armed force and not make the entire force excellent. And usually the air forces are picked for that.
The Kinzhal and Iskander-M are theorized to be related systems, yes. And air launch certainly requires extensive modifications, especially with regards to launch and guidance. It's quite easy to see why the missile you launch from an aircraft at Mach-Fuck and at high altitude would require more complex adaptations than the one that's positioned vertically by a truck and then already starts the launching process.
Kinzhal and Iskander-M are the clostest in-service example we have of a ground and air launched ballistic missile of roughly similar design and performance. And this example does not back up your theoretical assumptions.
Extra and Rampage ; Lora and Air Lora are rather similar. But there are no cost figures for them.
I certainly don't know of any modifications required to make one air launched. Given the velocities they are said to achieve from ground launch I don't see how an air launch at a lower speed than their max is in any way a particularly stressful event.
And does guidance really need to be much different? I don't see a reason for that either.
The way I see it, you're either:
- Taking a munition as-is and giving it a longer range and possibly terminal impact velocity which in turn gives it more effect for the same cost. (Same cost | More effect).
- Or removing an expensive first stage to give it similar capabilities as the ground launched. (Lower cost | Same effect).
So if the Kinzhal suddenly costs a lot more, it could be either that the Iskander's cost figure just hasn't been updated in a long time, or the Kinzhal received modifications that go beyond simple air launch capability.
