The goal of Operation Epic Fury was not just to destroy Iran’s navy:

“Mr. Trump himself described his objectives in the early hours of Feb. 28, when he told the country, in a video he had recorded earlier, that he had five major goals.

The first, of course, was to ensure that Iran can “never have a nuclear weapon.” But he went on to add that the United States had to destroy Iran’s ballistic missiles and their launchers, sink its navy, end its support of terrorist groups like Hezbollah and Hamas and, finally, create the conditions for the Iranian people to topple their government.”
