The FB-22 and YF-23-based designs are alternative proposals.[52]

Boeing's proposal appears to modify the B-1B into a design able to serve these two purposes. For the bomb-truck role Boeing proposes the modification of existing external hardpoints to allow them to carry multiple conventional warheads, dramatically improving overall warload. For the air-to-air role, both defensive and offensive, they propose to add active electronically-scanned array radar and allow some of the hardpoints to carry air-to-air missiles. Even with its somewhat reduced range as compared to the original B-1B, its fuel capacity remains quite large. This would allow it to escape from unfavorable air-to-air encounters by simply running away; there are few enough aircraft capable of Mach 2+ performance in general, and those that are deployed can maintain these speeds for only very short periods of time.[51]

In general terms the B-1R most closely resembles the original F-111 concept, as opposed to a pure bomber role. However, it would be able to carry out these missions at ranges even greater than the F-111.
