Just released - the design patent on Northrop Grumman's Next Generation Bomber concept.
Details: as expected, it looks smaller than a B-2. Four engines make life easier for the signatures group, because the smaller inlet duct can achieve the required radar-blocking curvature in a lesser length. Most likely, a single weapon bay on the centerline. And, as expected, a variation on the Northrop Grumman "cranked kite" planform family. And, overall, not too far from the concept that Jozef Gatial produced for us last year:

No wonder I was getting some odd looks from Northrop Grumman people. Another observation: some of the names on the patent are relative newcomers, this being their first patent for the company. The patent was filed at the end of 2007 - just before Northrop Grumman reported a major contract win, probably associated with the NGB project. For more background to the bomber project, start here.
