@oralloy,
Well, I am no expert by any means but I am sure Carrier Strike Group 1 carries a pretty good ordinance.
North Korea is only 46,541 square miles in size. Pretty sure most of the artillery aimed at Best Korea is on or near the DMZ pointing south. The provinces of North Hwanghae (3,148 sq mi), Kangwon (4,346 sq mi) and South Hwanghea (3,260 sq mi) would bear the brunt of the bombardment. I doubt you can throw a rock in that area without hitting something that goes boom.
Now, beside CSG-1 there is also a pretty good military presence in Best Korea and Okinawa. Though I doubt we will hear from GOB1 in terms of the amount of ordinance found in and around that area, I am sure it is enough to overwhelm what ever Worse Korea has.
