SAMs are great for shooting down big bombers, and planes like F14, 15, 16, 18, etc. But an A10 at 30' AGL is not an easy target for a SAM to even see, much less target lock, and shooting it down is difficult. A faster fighter has a good chance of getting shot down by an A10 also, because they don't do so well when the fight becomes low and slow. Different aircraft for different missions, the A10 is basically in a league of its own, and so superior in many ways, even all these years later. An A10 pilot is not going to mix it up with a few fighters at 30,000', they are going to get them to come down to 30' and dodging hills and terrain. Slow that fast fighter down to 150 knots and it is utterly useless, and has to accelerate and start to climb. The A10 turns and points the nose up and shoots down said fighter with ' THE GUN' as its known as. My Dad was born in the USA and is ex military, he always said that nothing else would he rather fly on this earth if he had to fly fixed wing, instead of rotary.
Wow, when have you EVER seen an A-10 30 feet off the ground other than passing through on approach or takeoff? My house is 30' tall. Maybe a wingtip dips to 30' sometimes, but I'd have to see it to believe they spend much more than a few seconds at that altitude. Heck, its own bombs would frag it at that altitude.
Look, I love the A10. It has its place in the kind of combat we've done in the last few decades. Yes, its gun is INCREDIBLE. But its day has passed for front-line service in a near-peer conflict in the highest threat environments. It just can't cut it there until air superiority is established and maintained.
The P-51 is sleek, fast, and has six awesome .50 caliber machine guns. I will be in awe and drool over that thing all day, but it doesn't belong in today's battlespace.
The A10 is loved because it makes a highly visible mess of insurgents who are trying to kill our troops. So the troops love it. And we've had so many troops see or even hear of stories of the A10 doing just that over the last 30 years that it makes it hard to kill. Especially when there are vets in Congress that have such fond experiences with it.
So politics has extended its life. If I'm an Army General, I'd rather have more F-35's supporting my troops, which are designed more to drop bombs than to be a fighter. But it looks more like a fighter, so people think it can't do the CAS mission. It can. And I'd bet it can do it better than any other platform in a near-peer conflict in a high AAA/SAM environment. It can drop guided SBD's right down the hatch of the threat, from a distance where the troops wouldn't see it, and so it would miss out on some of the glory. But I'd rather the pilot and plane stay safe to fight another day than to come down where I can see it just to make me feel better, to do the same job.
I'll add this, from reading Astro's posts, and others, yes, the A10 would have tremendous support around it from other aircraft. But that's the problem with it. An A10 is going to need a lot more other airplanes involved to successfully fly a mission in a high threat environment than an F-35. Lots more. All of a sudden the very expensive F-35 has a cost advantage, and not just in terms of dollars. In terms of manpower and resources, too.
It would be neat to get a former A-10 pilot in here who now flys the F-35. Bet he or she would not trade the new ride for the old one, any day, in any conflict.
