Just curious, not a "HTC MUST ADD THIS OR I QUIT" thread.
I've read that some of the late production F6F-5 Hellcats had their inboard .50's replaced with 20mm. I was interested in any more information there might be on this. Standard stuff... "How many?", "Did they see combat?" and so forth.
Thanks.
Oh and "Perk 'em!" in advance. Not sure what should be perked or how much, but I'm sure something should be.
