One takeaway from that:
“Launching 25 bombers on one mission is an impressive undertaking. Russia possesses just 70 Backfires, 58 Bears, and 13 Blackjacks. The 14 Backfires, six Bears, and five Blackjacks that reportedly struck Syria represent a significant portion of the overall fleet. The massive raid is evidence of improving readiness on the part of the Russian air force, which in the 1990s and early 2000s grounded most of its aircraft because it couldn’t afford to fuel them or pay their pilots.
“By comparison, on any given day 57 of the U.S. Air Force’s 77 B-52s, 35 of its 60 B-1s, and nine of its 20 B-2 stealth bombers are even flyable, according to statistics from 2013.”
This surprised even the Pentagon.
