And why is the unfortunate aircraft carrier (three lost FA-18s and a collision at sea) Harry S Truman called a “she?” I thought they were supposed to go by their gender assigned at berth

@Cdespinosa I know you’re making a (really good) joke. But the Imperial War Museum has less than satisfying info for you.

US Navy traditions come heavily from the Royal Navy, which in turn lost the reason for gendered ships ages ago.

Why do ships have a gender?

The naming conventions of the Royal Navy are part of a long tradition but other navies have a different approach.

@Cdespinosa Little known fact: Truman's mom allegedly said he was supposed to have been a girl.
