LEGO® Gato-Class Submarine MOC


Please login or create an account to download the building instructions.

This is the first one in the brand new series of “Sea Monsters”.

It is the Gato-Class Submarine, the first mass-produced submarine in the US during WWII. This LEGO MOC was built at a 1:500 scale (making it 19 cm long). It is not to scale with my battleship MOCs or other ships unless it’s on the equivalent scale of 1:500.

Built at an approximate scale of 1:500 [1cm = 500cm].
