This picture was taken either Monday or Tuesday.
That's Naval Base Coronado with NAS North Island (San Diego) in the background. From left-to-right it shows USS Carl Vinson (CVN 70), USS Ronald Reagan (CVN 76) and USS Nimitz (CVN 68). Each represents more tactical - and strategic - firepower than the entire KPAF.
USS John C. Stennis (CVN 74) is currently the only aircraft carrier deployed in the Pacific, and as of this week it is on a liberty call to Singapore. If it left today, it could be within 200 miles of Pyongyang by Sunday afternoon.
Terrain? Say hello to my little friend
His name is GBU-57A/B, the Massive Ordnance Penetrator. It's 30,000 pounds worth of don't give a f**k about terrain.
The North Korean air defense network is very similar to the one that was ground to dust in Iraq in 1991, except it's older and has been maintained and 'updated' by North Koreans. (Advantage: U.S.) The Iraqi campaign went on for about six weeks, but the combat effectiveness of the air defenses and that of the air force itself was essentially zero after 36 hours. This represents the last truly hostile potential threat environment for which aircraft like the B-2 and F-22 were designed to exploit. And it should be noted that the F-22 has not yet been 'shot down' in any training scenario that even remotely mimics how the aircraft would be employed in a hot war.
