Remove the 20mm.... I thought it was pretty well established and shown these were removed?
With the speed and mega-alt these bombers get, i would not worry about the 20 mm but worry how the hell i am going get to the bomber, keep up with it and then then shot it down.
Well, it'S exactly the speed & alt that makes one worry about the 20mm. Will be very hard to set up attacks that do entirely avoid the 20mm. And just think about how dangerous the 20mm on the Ki-67 already is...
No such gun existed in combat! http://bbs.hitechcreations.com/smf/index.php/topic,305406.msg3947431.html#msg3947431
We have plenty of excellent aircraft that more than capable of taking a B-29 formation down. Easily in fact.
if someon is going to take 30 mins to get to altitude to do one bombing run - then kudos to them.
