The frog is a steampunk / dieselpunk deep-sea vehicle designed by me in 2020-2021, which was strongly inspired by armored vehicles of the first world war. However, its purpose is completely non-military. It is mainly used for towing heavy trailers underwater and for transporting divers between deep sea stations. The name of the vehicle is based on its flat shape towards the rear and its large front, as well as its ability to function both above and below the water. A little bit like a frog.
