The largest submarine I have ever made. Solid all the way through. Weighs about five pounds.
About this creation
This submarine was created during the "Deep Sea Race" in the late 2020's. At the time it was the largest and most advanced submarine ever created. It could reach a depth of nearly four miles below sea level, thanks to a very powerful Structural Integrity Field generator. It holds a crew of about 650, and has 12 decks.
