Rockwell B-1 Lancer Supersonic Strategic Bomber Family
The Rockwell B-1 Lancer is a variable-geometry supersonic strategic-bomber family that began with the high-speed B-1A development aircraft and returned as the conventionally focused B-1B. Its swing-wing planform, terrain-following mission, and long-range performance made it a defining late-Cold-War bomber design that remains in United States Air Force service.

- B-1B exact F101-GE-102 configuration
- Notes
- Applies only to the B-1B production branch. The B-1A/YF101-GE-100 prototype installation, other B-1A/B-1B alternatives, and unsupported engine suffixes remain separate or unmodeled until exact evidence supports them.

- Variant Notes
- Four exact General Electric YF101-GE-100 afterburning turbofans mounted in pairs beneath the fixed inboard wing section of the B-1A; no F101-GE-102 substitution or other B-1 branch is inferred.

- Notes
- Applies only to the B-1A development/prototype branch. The sealed B-1B/F101-GE-102 alternative is preserved; production B-1B, other B-1A test aircraft, and unsupported YF101 suffixes remain separate or unmodeled until exact evidence supports them.
