Satellite imagery taken after the US strike on Iran’s Fordow site showed smoke rising from the fuel enrichment plant. US President Donald Trump claimed key Iranian nuclear sites had been “obliterated,” while Iran claimed it had removed nuclear material from the sites before the strikes.
Bunker busters only have about 2kg of payload, the rest of the weight is the penetrator body.
The bombs are rated at destroying a 20m radius.
There is some evidence that these penetrators can be guided away from targets by clever architecture. (A reinforced diamond cross-swcrioned concrete beam for instance can guide the penetrator away from its target)
Long story short we don’t know if these did anything.
