In the Yalta and Potsdam conferences, the Allies established their joint military occupation and administration of Germany via the Allied Control Council (ACC), a four-power (US, UK, USSR, France) military government effective until the restoration of German sovereignty. In eastern Germany, the Soviet Occupation Zone (SBZ – Sowjetische Besatzungszone ) comprised the five states ( Länder ) of Mecklenburg-Vorpommern , Brandenburg , Saxony , Saxony-Anhalt , and Thuringia . Disagreements over the policies to be followed in the occupied zones quickly led to a breakdown in cooperation between the four powers, and the Soviets administered their zone without regard to the policies implemented in the other zones. The Soviets withdrew from the ACC in 1948; subsequently as the other three zones were increasingly unified and granted self-government, the Soviet administration instituted a separate socialist government in its zone.
German Heavy Warships - At the beginning of the month, heavy cruiser "Admiral Hipper" sailed from Brest. On the 12th , far to the west of Gibraltar, she sank seven ships from slow unescorted convoy SLS64 bound for Britain from Sierra Leone. Returning to Brest, in March she heads back to Germany via the Denmark Strait and took no further part in independent commerce raiding. On the 8th , battlecruisers "Scharnhorst" and "Gneisenau" sighted convoy HX106 escorted by the lone battleship "Ramillies" south of Greenland, but declined to attack in case of possible damage. Two weeks later, five unescorted ships were sunk east of Newfoundland, before they headed for the Sierra Leone routes. Meanwhile pocket battleship "Admiral Scheer" in the Indian Ocean operated successfully off Madagascar before preparing to return to Germany.
In support of new operational priorities, there are future plans to equip the 212A with a land-attack capability. The Interactive Defense and Attack System for Submarines (IDAS), currently under development by Diehl BGT Defence, HDW and Kongsberg of Norway, uses a wire-guided missile to engage helicopters and mobile targets on shore. The third Type 212 submarine, U33 was selected as the platform for testing the new weapon. The missile made the first flight in June 2008, successfully launched from the torpedo tubes of the submerged submarine.
