This is a quite accurate model of Peral´s sub, with detailed interior. Has animated propellers and rudder,as well as some other features, like torpedo load and torpedo launch. Most of details have been taken from existing pictures, but the interior viewing system remains a mystery, since Peral dismantled it, it seems it was a totally revolutionary concept. Electric and Diesel engines have also been detailed from builder´s blueprints . The model has a high poly count , and this helps to capture lights, so it renders very well. The sub´s main task was torpedo attacks, and the design reveals this, batteries also fill a great amount of existing room, and the sub has not double hull, it carried no other weapons.
