This thread is a rabbit hole of steam-powered early submarines. They also saw real combat use. Found a nice history video.

Side note, modern nuke subs use steam, too.

Was this a steam-electric propulsion at the time, or something more exotic? Plain steam power underwater, as long as it lasted?

Underwater boiler efficiency is lower as outside pressure increases. Keep sub insides at 1 bar? Or dive only 5m deep?
