the United States Air Force has only one dedicated close-support fighter, the Warthog / A 10 (thank you George !)

It has a 30mm Gatling with the payload capacity of four B-17s.

The Air Force, though, doesn't seem to care much for the Warthog, and has been trying to get it out of service. 

the Air Force has stopped training Warthog drivers, and depot maintenance operations on the A-10 are wrapping up. 

Now, though, there's a new bill in Congress to keep the 'Hogs flying for a few more years: It's called the Bolstering Recognition, Resurgence, Retention, and Remembrance of the Thunderbolt Act.

That's right. It's the BRRRRT Act.

We've learned from the war with Iran how useful a flying Avenger cannon can be, and that's prompting a lot of people to take another hard look at keeping them around. The BRRRRT Act proposes to keep at least 126 Warthogs flying.

There's still a place in the modern battle space for a dedicated, low-and-slow, dedicated close air-support airplane, and the A-10's a very, very good one
