It has it’s place, but any reasonably skilled pilot knows that the first thing you do when slotting in behind someone for a shot is to check your surroundings for someone in a position to slot in on your six. Basic awareness of the situation renders low G missiles non-issues, so long as you have some energy to play with.
Around about 8.3-8.7, the comparative power levels of CAS start to become very wide. Before then, any reasonably agile, reasonably small airframe with a useable anti to ground loadout is useful, and the gap between the various planes isn’t that big. A P-47 is impressive, but you can just as easily take out a Bearcat, a Typhoon, a Do-335 or other comparable options and do just about as well.
But after that point, as SPAA becomes far more competent, CAS options become far more restrictive. CCIP on smaller airframes works at a lower BR, or with careful pop up attacks, but from about 9.0 onwards you really want guided munitions, preferably fire and forget or otherwise self guiding.
My point is the BN isn’t a great example here, as while it’s CAS ability isn’t completely appalling, it’s not as good as other options, like the Swiss Hunter which gets two fire and forget Mavericks on an overall better platform. You have to judge CAS versus SPAA against the high water marks, not just against whatever plane can be taken up at that tier.
If the CAS vehicle is loitering over the battlefield, then surely all it would take is to spawn one of these supposedly undodgable SAMs and deal with him that way, right?
CAP’s primary advantage is that it can reach and shoot down CAS that’s avoiding friendly SPAA, principly by sitting at it’s maximum range and salvoing off guided munitions. That, or intercepting CAS before it gets into firing range, by camping the enemy airspawn. Using it to shoot down CAS over the AO is generally a waste, as you rightly point out, it’s highly vulnerable to enemy SPAA while doing so.
Without aircraft spotting, missiles are a credible threat. Even 10 G start missiles can catch people out if you sneak up on them. Similarly, you can use the lack of spotting to sneak into range to onetap them with a burst before they even realize you’re there.
Unless there’s any amount of obstructions in the way. If the target plane is at reasonably low altitude and diving, the missile will overlead right into the ground. If they’re going tranverse, it will hit any useful cover near you.
You made an incorrect manuever. Just pulling in one direction isn’t going to spoof the missile. It can pull 13G, you can pull 8G. I think you can do the math on that.
That’s why you roll at the same time. Picture in your head the missile’s target lock. It sees your plane and where it’s headed, and adjusts it’s lead to intercept that course. You pull in one direction, it follows you, and since it has enough G limit it will hit you.
Now pull, and start to roll. Now, it’s pulling 13Gs in one direction, only to have to pull it around in a circle to keep trying to intercept your course. Meanwhile, because your plane is actively rolling, it’s not getting anywhere near where the missile thinks it would be if it just kept pulling in the direction it’s currently pulling. At the same time, the missile is pulling maximum Gs in opposing directions, bleeding it of energy, and making it less easily able to pull back in to hit you.
Speed bleed always helps. It helps against jets even at maximum thrust, and it helps against missiles with burning boosters (To a lesser extent, admittedly, but still).
He can pull it off, meaning replicated what he does, anyone else can too. The only difference is having a decent monitor, allowing you to use the terrible optic from slightly further. But other CAS options with better optics exist at the tier.
