I find it frankly hilarious that all these ships are apparently designed so that damage to just about any part of the ship has a high likelihood of causing a bridge panel, often used by the captain, commanders, and lieutenants, to explode right into the faces of the most important people on the ship.
You would think after reading the 20th captain’s log with variations of “Ensign Ricky died after a bridge panel exploded in his face following minor torpedo damage to Shuttle Bay 3,” Starfleet might consider some redesigns and retrofittings.
Other way around.
An acronym is a type of initialism, which is itself a type of abbreviation.
So acronyms are initialisms where you pronounce the letters like a word (e.g., RAM), initialisms are abbreviations made by taking the initial letters of multiple words and concatenating them regardless of how it’s spoken (e.g. FBI for Federal Bureau of Investigation), and an abbreviation is any shortening of a word or phrase into something shorter (e.g., “abbrev.” for abbreviation or “US” for United States).
