The US Navy released footage that showed a bombing exercise of the U.S. Navy that was carried out on June 18. 

The explosion of a 18,143 kilogram bomb​ was conducted underwater as part of a trial to test​ of USS Gerald R. Ford CVN78 Carrier. It was intended to show how durable ships are when confronted with a bombing.​​

The exercise took place off the coast of Florida. The explosion was so powerful that it caused a 3.9 magnitude earthquake roughly 160 kilometres away​.​
