Gun Val Program
What did this program actually achieve during the Korean War when a number of F-86F's were fitted with four 20mm cannons instead of the standard ..six 50 caliber's ..
Was 4 better than 6 Operational wise in terms of bullet usage ??
It was done probably to appease European customers more than anything else. By the time 20mm were being fitted this jet was looking to be replaced by the F100 and a bunch of other designs.

USAF pilots had complained that .50s didn't have the destructive power needed to reliably knock down MiGs.
