So I've been thinking about the Galaxy and how it could be changed in order for it to be useful again. While there are plenty of possible suggestions, I just wanted to focus on one: it's gun placements. To be frank, they're terrible, and I'm probably not the only one who's thought this. The tailgunner is okay, but the side guns have very little arc. Therefore, any airplane can easily swoop in from the top or bottom (as long as you avoid the tailgunner field of fire) to chip away at a Gal until it explodes. So the Galaxy is largely unarmed, since its guns can only cover the sides, back, and part of the bottom.
So a feasible, yet effective solution would be to take the side 20mm guns and place one on the top of the plane and one on the bottom. Mount them on small turrets so they can rotate a full 360 degrees and swivel from 0 degrees (level) to 90 degrees straight up (or straight down for the bottom turret). That way the firing area of each gun is a hemisphere that can very effectively engage air targets. The bottom gun would also serve as a light anti-ground weapon as well.
This change would effectively protect the entire Galaxy. The two weak spots would be directly in front and directly at the sides, but an enemy airplane would have to fly straight for those sections in order to avoid incoming fire, a tactic that would require many passes and therefore take much longer. I figure that this would be a much simpler change than a complete overhaul of the Galaxy. If possible, I would even add another 20mm gun to the existing ones for extra firepower. The Galaxy could use some more perks, anyhow.
So those are my ideas. Comment on them or post your own.
