I've copied two paragraphs from Joe Baugher's website and these only
apply
to the B-52H.

Hmm, according to my books on the BUFF, the 20mm cannon was a "stock item"
on
the H model.

You want to reread that first paragraph which reads "The defensive tail
armament was changed. The quartet of 0.50-inch machine
guns carried by earlier versions was replaced by a single General Electric
M61 20-mm six-barreled rotary cannon. "

It says the .50s were used on EARLIER versions. My experience was with Ds
and Gs. The 20mm was only on the H which is what my message said.
