For its time, AD Skyraider was a better plane - lower and slower. Flew from 1946 until they literally flew the wings off in Vietnam. The single engine AD was designed originally as a torpedo bomber to replace the Helldiver and Avenger. It could carry more bombs than a B-17.
Marines with squadrons in Korea reported that some crashed on landing because of mud on the windshield or telephone wires entangled in the flight controls. Now, THAT is low and slow.
All in all, the Warthog fills some mighty big shoes. Would dearly love to see what my Marines could do with it.
I know of the Skyraider but not how it stacks up against the Warthog. The A10 is basically that huge Gatling style cannon with wings attached, and an armored tub to protect the pilot.
It’s really an infantry support weapon and ought to be given over to the Army and Marine Corp. The Air Force objects because in their provincial stupidity they see that as an encroachment on their fixed wing aircraft monopoly. Disgusting that any service would endanger others over such petty inter-service rivalry.
