The utilitarian fuctionalism and rugged design of the equipment is something we do not see often in military equipment these days. Everything about a B-17 was overdesigned. They were rugged.
A turret like that on a osprey with twin 50 cals would be awesome. Or even twin miniguns.
Two Ospreys could generate enough suppressive fire to land troops in the middle of a firefight if necessary, or land in the middle of a fire fight to extract troops.
I hope they go with it.
You know, I have an M42 paratrooper's top...it's as functional and every bit as rugged as anything I was issued 50 years later (although I think the Gore-Tex ECWCs will also go down as a military classic). I also think the M1 carbine is extremely under-rated for what it represented in the way of weapon design...
