The HASE (rabbit) was an advanced model of the Marder-class midget submarine created in Germany during World War II and operated by K – Verdand. Its prototype performed poorly during test runs and therefore no other boats were produced.
Professor Cornelius tried to put on the “Marder” Walter turbine operating on ingolin (Ts. Stoff). But it has not brought success.
Then add one more section of the hull, with extra batteries. It also has changed the system of boat control. Added more depth rudders. However, mass production, “Hase” build failed. This is a scale plastic model kit, assembly required. Paints and glue not included.
