I'm actually somewhat surprised Iran is openly telling us they are using underwater drones for this. That piece of technological advance has gone mostly under the radar (!) so far.
The Ukraine would like to have a word.
For example - https://en.wikipedia.org/wiki/Sea_Baby#Sub_Sea_Baby
Similarly you say "The commonwealth of Massachusetts" but not "The Massachusetts".
This does not apply to Ukraine, unless you want to say "The Republic of Ukraine".
Of course that could be the entire idea.
