Lots of ways to defeat people and things hunkered down underground. Although I would guess that a modified c-130 , built to carry and release a 30,000 pounder could be available.
The ramp in a C130 can already take a 15,000lb airdrop no reason to think it cannot take a 30,000ib load in a slight climb.
The daisy cutters out a C130 it all it’s 15-000lb glory.

Remember we dropped a Fing ICBM out of a C5 at nearly 90,000lbs total weight including the pallets and chutes so the physics is right.
Bank on this is the way if we don’t just fly the B2 over for them. Either way that facility must be rubble or they just pick up where they left off. Plus it is symbolic to the Republic of Iran and they must be crushed and a new regime in place before this ends nothing short of that is acceptable to Israel. If we don’t want them to go nuclear we must help them to that end. They will use nukes ask any Jew if using nukes against Iran is off the table to save Israel be prepared to be e your head snapped back with how fast they will tell you in no uncertain terms they will nuke Iran in a war. That war is here today right now.
