No, close air support does not mean being close to the ground. It means engaging targets in close proximity to friendly forces

> In military tactics, close air support (CAS) is defined as aerial warfare actions—often air-to-ground actions such as strafes or airstrikes—by military aircraft against hostile targets in close proximity to friendly forces

https://en.m.wikipedia.org/wiki/Close_air_support

With guided munitions and better targeting pods, close air support has shifted to dropping precision munitions from further away to minimize the risk from short range air defenses.

The problem with precision munitions is that you cannot manufacture, transport and drop enough of them to achieve as much as you can with bullets. The country footing the bill is likely to be impoverished by them if used at any large scale. :/

You need to be close to the ground if using bullets.

As I point out in another comment, the cost of a laser guided bomb is $20K [1]. Less than the operational cost of flying the f-16 for one hour [2]. The idea that precision munitions are prohibitively expensive to use for close air support is a fantasy.

Now I think the F-16 is prohibitively expensive. Interestingly, the A-10 costs $19,000 per hour to fly too:

Lets say we have 6 targets and a 2 hour mission. Let us assume that the F-16 and A-10 both cost $20,000 per hour to fly. That would be $160,000 for the F-16. Lets assume the ammunition for the warthog costs $1 each. That would be $40,780 for the A-10.

Oh, and the F-35 costs about $40,000 per hour to fly. For that, the same mission costs $200,000.

Unfortunately, the math does not favor those munitions.

Except they don't don't $1 each. They cost $136 : https://www.quora.com/How-much-does-a-30mm-GAU-8-round-cost

That's not counting wear on the gun.

And if flying low to strafe results in even one additional loss, all those savings are even more than offset.

But more importantly, this whole comparison is moot because for every hour flying a combat mission, a pilot is flying many more hours in training.

While those are pricy, the military does not fire those from the A-10 anymore:

> Armor-piercing incendiary rounds “go through soft targets very cleanly and don’t do much damage unless they hit a critical component,” said the former A-10 pilot. “The type of targets in Iraq and Afghanistan did not warrant using API.”

Non-incendiary rounds are much cheaper. I cannot find an exact price on it, but I imagine that they are negligible in comparison to fuel.

[Manuel_D]

They don't cost a dollar a round, I'll guarantee you. Standard ball .50 BMG ammo is $3 a round on a good day, incindiary is even more than that. I'm very curious how you got this figure of $1 for armor piercing incindiary 30mm shells.

If flying low saves the life of 1 additional solider, it would be worth it.

[Manuel_D]

And conversely, if precision munitions saves the life of 1 more soldier than strafing, it's worth it.

they're cheaper than replacing a plane and especially its pilot I can assure you that
