Prior to the introduction of “smart” weapons, attacking tanks directly with aircraft was, in purely materialistic terms, incredibly difficult and certainly inefficient.
While pilots claimed massive numbers of tank kills, careful examination when the dust settled revealed a different story. In WWII, it was 5-8%, depending on how you fiddle with statistics. By Korea, the 100% confirmed aircraft kills of tanks had risen only modestly, to 12%. Granted, this is a slight lowball figure because a lot of the “unknown” losses were to aircraft napalm. If every single “unknown cause” loss turned out to be due to aircraft, it would rise to 40%, but this is doubtful, and the modest point still stands.
As this video shows, attacking and disrupting the soft-skinned support elements was something air power at the time was far better equipped to handle.
One thing I’m legitimately curious about (and haven’t read that much on, hence my curiosity) is the height to which “dumb” (albeit ballistic computer-assisted) rockets and bombs could reach with postwar technology.
