The US military has a long history of making technically true statements about it's weapons, but which are still misleading.
If a bomb can actually rip through 200 meters of cement and ground, then the 60 meter statement is also true.
It also has a history of revealing the actual limits of weapons systems, but only after better capabilities exist (with the limits of those still classified or understated) - that is the 60M limit was the max of the old bomb and they don't need to know about the new one.
I can see how it comes off as dismissive my bad - it was intended to be a "take such analyses with a grain of salt if you aren't privvy to classified, relevant information".
