Lots of tankers, recon, command and control aircraft over the United States tonight. Bombers don’t track. Wonder if it’s part of the culmination of STRATCOM exercise Global Thunder. Tonight/early morning also has scheduled Minuteman III ICBM launch.

A US B-52 apparently conducted a flight test of new long-range (unarmed) nuclear cruise missile (LRSO). Photos who two missiles under the wing. Report below.
LRSO will arm both B-52 and B-21 bombers from the end of this decade.
