Originally built as a supersonic strategic bomber for delivering nuclear strikes on Moscow, the B-1B Lancer has played a variety of roles for the US Air Force in its nearly 30 years of service. And thanks to a newly upgraded cockpit — including four multi-function colour displays and a modernised Fully Integrated Data Link (FIDL) — the B-One “Bones” of the 7th Bomb Wing are expected to remain in service into the 2030s.
