A fictional submarine by Jules Verne’s 1986 novel. It is a British Royal Navy assets in Facing The Flag.
The sub can carry 4 crew and lead by a lieutenant. Based on this submarine design many animation series and games has used its design, mainly animation that uses Steampunk theme.
Example like Bioshock, Laputa Castle in The Sky and many more.
Well according to my research in English this is the origin of this fictional submarine. In the instruction template it came with its own description, but it is in Russian/czech and I can’t read Russian/czech.
Description might have said something entirely different so please forgive me if I’m wrong.
