Regnum Irae!In answer to your query as queried :The Type XXVI was a high-seas U-boat propelled by the Walter Propulsion System. They would have had a crew of three officers and 30 men, with ten torpedo tubes, 4 at the bow and 6 in a so-called Schnee organ, and no deck guns. 100 contracts were initially awarded to the Blohm & Voss yard in Hamburg (U-4501 through U-4600) and sections were under construction for U-4501 through U-4504 when the war ended. The other contracts had been cancelled.
The projected performance figures included a submerged speed in the area of 25 knots, and a surfaced speed of at least 18 knots. A diving depth of about 1,000 feet was built into the design, though whether it could have been safely reached is open to debate. Other German designs intended to operate at such depths proved incapable of actually reaching it without serious leaking problems.
Armament would have consisted of ten 533 mm (21-inch) torpedo tubes. Four would have been located in the usual place in the bow, with six more located approximately amidships, firing aft. Access for both sets of tubes would have been from the forward torpedo room.
The Type XXVI would have been the first German combat submarine to have it's attack center located in the control room. Previous designs put the captain in the conning tower. In the Type XXVI, the conning tower contained only an escape trunk. The usual two periscopes would have been provided, a night periscope with a large objective lens, and an attack periscope with a very narrow head to minimize the chances of it being spotted during the day.
While the Walter turbine would have allowed a very high submerged speed for chasing down a target, or escaping an attacker, the need to carry huge supplies of the highly-corrosive hydrogen peroxide fuel limited the use of turbines. For normal propulsion, one of these boats would have used its diesel engine or electric motor. A Schnorchel was fitted, and the head would have been covered in the usual anti-radar coating and contained the most advanced radar detector available.
Plans also called for inclusion of the most sophisticated sound gear available. German designs were sophisticated, indeed. Late war German designs included phased array hydrophones, which could be electronically "steered," and became the basis for post-war American systems development. Other refinements, which were being tested at the time and might have been included, included the first wire-guided torpedoes.
