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.

[ryao]

Whatever the cost is, expect it to be neligible, such that even if it were $10 per round, it would not make a difference.

That being said, I do not think the cost to the USAF is public. I picked $1 since no figure that was reasonable would make any difference.

[Manuel_D]

It costs $53 dollars a round, not $10: https://www.dacis.com/budget/budget_pdf/FY10/PROC/F/352010.p...

And again, the point is moot because there way more flight hours to train a pilot than spent flying combat missinons.

[ryao]

The original article said that they used a mix of those rounds and dummy rounds, so the costs are actually lower, but lets assume $53 per round:

3900 rounds per minute / (60 minutes per hour) * 2 seconds per shot * 6 shots * $53 = $41340, compared to $20,000 * 6 = $120,000.

The total cost is half for the A-10 after you add the cost of fuel. However, keep in mind that this does not consider that they also fire the "dummy" ammunition that is just regular bullets.

> And again, the point is moot because there way more flight hours to train a pilot than spent flying combat missinons.

Assuming that a nation is able to keep funding these missions during peace time, then the only real concern would be the costs during war time, which will undoubtedly be prohibitive.

That being said, the A-10 has a history of doing far more in CAS roles than other aircraft. That is because the A-10 is simply better at it.

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

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.

An A-10 could drop those in addition to firing bullets. Intentionally limiting capabilities by getting rid of the A-10 in favor of the F-35 would be endangering lives. :/
