b72 is much better, trust me we've been developing that stuff, b52xe is an improved version of the B52, ours is awhile new type of big bomber, although the design is similar
It's redesigned from the bottom, up. It uses a variety of elements from the original B52, but it's not just a re-skin or anything.
How much you want for one?
$150 million. (AC-130 is $190 million)
It features carpet-bombing capabilities and the ability to launch 6 AA missiles or two SCUD missiles. May be used to jam enemy radar. Has two HMG turrets. Maneuverability is greater than that of a B72, and is faster, but armor is not as thick.
B17XE is in production, if you want to wait an estimated time of 4 years.
