The US military dropped multiple GBU-72 bunker busting bombs to hit Iranian missile positions.

The US Central Command stated on social media on the 17th local time that the US military used multiple 5000-pound bunker buster bombs to strike Iranian missile sites along the Strait of Hormuz. It was reported that the model of these bunker buster bombs is GBU-72. The US Central Command claimed that the location targeted with the bunker buster bombs was where Iran had deployed anti-ship cruise missiles, posing a threat to international shipping in the strait. An unnamed US official stated that the US military used GBU-72 bunker buster bombs, which is a bomb model that was first used by the US military in 2021. An announcement by the US Air Force in 2021 stated that the GBU-72 was "developed specifically to address the challenge of targeting hardened, deeply buried targets."
