Just over 7,300 Km. Allowing few hours on task say 16,000 Km sortie.
It has a quoted combat radius of around 5,200km, but presumably will have tanked outbound and inbound.
Cruise speed just over 700km/h, so that’s 10 hours out and 10 back plus TOT. Doable, the B-52 and B-2 do longer - though I think they’re probably quieter and more comfortable inside.
