Slightly off topic, today I learned there is a Naval Yard in Portsmouth, Maine. It did genuinely confuse me for a second because Portsmouth UK is also a historically important dockyard where BAE systems, who build the UK submarine fleet, still have an important presence.
It's an especially confusing situation because Portsmouth Navy Yard is kind-of sort-of in Kittery, Maine, not Portsmouth, which is in New Hampshire. It's an island in the river between the two and the only bridge connects it to Kittery, not Portsmouth. This was part of a border dispute between the states: https://en.wikipedia.org/wiki/Piscataqua_River_border_disput...
