At 1500 ft., it would require 13 of our bunker busters to reach that depth...and that presumes precise follow up strikes on the same spot and pretends that the rubble from the previous strikes evaporated.....

[each bomb is good for 40m of hard rock]

Better idea: Secure the area around the entrances and go through the front door, one blast door at a time as we make way through the tunnels.
