The Biber was one of the weapon systems developed during the Second World War at the time when the situation on both fronts was gradually becoming worse and worse for Germany. In it became clear that the Allied invasion would take place soon somewhere on the Atlantic coast of the continent and the German military began to seek and develop new and rather unorthodox weapons to avert the invasion. Along the Neger, Marder and Hai manned torpedoes, also the Biber and Molch midget submarines were to stop the invasion fleet.
With the massive intensification of anti-submarine warfare in the Atlantic, the efficiency of classical U-Bootes — particularly those of type VII — was diminishing while seeing the losses increasing, at a point of rupture. Classical U-boote operations shown their limitations. Costly in men, oil and raw materials, large U-boats were no longer efficient.

German shipyard plans to enter the midget submarine market with new design On 6th September German shipyard Nordseewerke Emden revealed plans to build a new class of midget submarine, with a proposed launch date of The design appears aimed at the export market, particularly countries with existing relationships with German shipbuilding. Despite the small size the N has a relatively large diameter hull allowing two decks. The design is double-hulled with ballast tanks and torpedo tubes in the outer hull.

A midget submarine is a small one or two man submarine driven by its own propulsion system. It does not have any living quarters which meant that there was no toilet and no bunk space, just a simple cockpit for the crew to steer and launch its torpedoes. Without living facilities, a midget submarine could be deployed only for short missions.
The Neger design was unable to fully submerge, and therefore could only remain on the surface, making it extremely difficult for the operator to escape once firing the torpedo. The Marder is 26 feet long by 20 inches wide, and broken into three different sections. This particular artifact has been restored to a grayish-green color, with a white interior.
A midget submarine also called a mini submarine is any submarine under tons,  typically operated by a crew of one or two but sometimes up to 6 or 9, with little or no on-board living accommodation. They normally work with mother ships, from which they are launched and recovered and which provide living accommodation for the crew and support staff. Both military and civilian midget submarines have been built.
It makes sense seeing as they played a role in the attack on Pearl Harbor — in fact, one such submarine was found beached near Oahu, exhumed, and then taken on tour to help the U. None of these subs racked up the huge kill counts of their full-sized counterparts. One of the big reasons for that was that these submarines just didn't have a lot of speed one of Germany's most successful mini-subs could reach a top surface speed of seven knots. They also lacked endurance.
