So for those of you that don't know the B-1R (BoneR Please Register or Log in to view the hidden image!) is the proposed replacement for the current B-1B fleet. Its most interesting improvement in my opinion is the replacement of it's old engines with the Pratt and Whitney F119 engine which could enable it to hit mach 2.2 There are precious few military aircraft that can hit mach 2.2 and I don't think there are any that could maintain that speed nearly as long. Here's some info http://bagera3005.deviantart.com/art/Boeing-B-1R-Lancer-98328881 http://en.wikipedia.org/wiki/B-1_Lancer#Variants So what do you guys think? Worth it?
