I’ve always been interested in naval hijinks, mostly because navies are the premier means of “projecting power” for nation-states.* And, of course, gathering intelligence as well. The US’ military has a huge emphasis on naval force-projection because of the logistics of having a navy: a carrier task force group is a movable city with its own inner supply chain. As mentioned elsewhere, you can tell a lot about the purpose of a nation’s military by its force structure.
