"dropped 45 2,000lb bombs on Libya. I wonder where. Isn’t that what they call bunker busters?"
On the airfield at Misratah some 100 miles east of Tripoli.
At tricky question. Because there where bombs that where called bunker busters used years ago that weighted 2KT. But we today normally think of bunker busters to be GBU-28/BLU-113 smart guided bombs that weight well over 4,000 pounds. Following is but one site that will give you an idea what they look like
Here. So why this particular airfield? Because it is where many of the military aircraft take off from and land and has a number of hanger facilities cordoned off for military use rather then civilian traffic.
