Please tell me why you talk about a submarine in singular form while I can clearly see three different submarines in the picture series?

This is the flagship of the Chink navy

definitely made in china

the first one needs a welder eh?

dolphin tail fins are horizontal, this one is vertical. clearly shaped like a shark.

I've seen a much better looking dolphin sub about 5 years ago!
