[quote="hoom"Didn't know that, makes an 8* Onyx salvo quite a lot more scary than I'd been giving credit for.[/quote]
It showing that you never spend time to consider/calculate the chances for this type of missile.
Basic rule is every unit has to use 4 sam for one target.
By the historical experiences the SAM has quite low hit probability, the Israel iron dome has something like 70-90% against subsonic non manoeuvrable, ballistic targets.
Here you have manoeuvring, supersonic ( 2-4 match ) fast , high G capable small radar cross section targets, that can see the incoming missiles as well ( if not now then after a electronic pack update) .
The Onix is at the end of its trajectory, means it can accelerate by 2 g with its engine, and can turn by dozens of gs.
And the ship has 50 seconds to do anything about it, means if it can launch say 4 SAM / seconds, then it can have 200 in due time, but it will be a bit difficult to illuminate all targets for the 200 sam, considering that the AB has only 5-10 illuminator.
Means that if you consider the realistic scenarios then the best chance for the ship to survive is if it using chaff and ECM .
And that is the reason why they communicate with each other and prioritise the targets : )
The subsonic is a bit different, in that case the ship can launch 600 rocket, means that by simple calculation it can kill at least 3 times more subsonic rocket than supersonic ones.
