Is that so? I was assuming ,with commonality in mind, that they all had the same gun in the same place.
Wiki: The F-35A includes a GAU-22/A, a four-barrel version of the GAU-12 Equalizer 25 mm cannon.[140] The cannon is mounted internally with 182 rounds for the F-35A or in an external pod with 220 rounds for the F-35B and F-35C.[141][142]
