Project history

Oceangoing submarines for operations in far areas. The design was developed on the basis of U81-86 submarine cruisers of the period of the First World War with application of decisions included in the I series. Double-hulled, maximal diving depth was 200m, minimal diving time was 35sec. At the same time, the big dimensions done these submarines less mobile and manoeuvrable and fast in submerged position.

Series IXC had even more increased dimensions and other arrangement of oil fuel tanks. Advanced IXC/40 series had improved electronic equipment, and on last boats of this subgroup the deck sheathing was sheared for diving time reduction. In total 134 IXC/40 series submarines were ordered, but in the mid-1943, in connection with moral obsolescence of the project and reaming of mass building of XXI series, part of orders was cancelled. U882, U890 and U891 were destroyed during outfitting after launch.

All boats of a series were distinguished by presence of three periscopes. Instead of torpedoes 44 TMA or 66 TMB mines could be carried. Strengthening of antiaircraft armament has begun from late 1942. 37mm gun was transferred from a deck to a special platform ("Wintergarten") behind CT (under which two additional spare torpedoes were stored), instead of 1 single 20mm MG 2 single or twin such MGs were installed, 105mm gun was removed. From the second half of 1943 submarines received snorkel.

Modernizations

1943 - 1944, most survived and completed boats were rearmed with artillery consisted of 1 x 1 - 37/69 FlaK M/42, 2 x 1 - 20/65 C/38 or 2 x 2 - 20/65 C/38 or 1 x 4 - 20/65 C/38

1943-1944, most survived early built: - S-Gerät sonar, FuMB 1 Metox ECM suite; + FuMB 3 Bali, FuMB 6 Palau ECM suites

1944-1945, some survived: - FuMO 29 radar; + FuMO 61 radar
