My understanding is that it does have an integral bomb bay. It could be unarmed only in the strictest sense —i.e. this copy contained no internal weapons store at the time of photo.
I think the F-22 will be the last of the high-ticket manned systems, or those that carry humans will do so only as an option.
The first photo of this platform was 18 months ago, but the unit was in-flight and the quality of the photo was not nearly as good.
One of the most impessive new systems I saw (just last week) was a military application of what that crazy French-swiss bat-man guy does with the single man backpack jet.
These units are for SF troopers, and they are stealthy, good for delivery of one trooper only, and the range is only something like 40 miles.
