If they can't come up with an equally effective replacement for the A-10 - and I don't think the Air Force even wants to do that because they generally don't prioritize close air support -- that would be great.
But until they do come up with that replacement, they need to keep what still works.
You beat me to the punch. I was just going to mention that the Ma Duece has been in service since 1933, 83 year, based on John Browning’s design of 1918.
That’s probably a world record for efficiently dealing death and destruction and still going strong.
