Ship project history: Originally consisting of twelve boats, this class of coastal submarines belonged to the Type 201 and was first designed as 'U-Boot 55' by IKL. The boats were to be section-built and were ordered in March 1959. In November 1958 it was decided that the hulls should be non-magnetic, but the material used quickly showed corrosive defects. In June 1962 U1 showed the first signs of structural weakness which quickly increased so that U1 and U2 had to be decommissioned. Later they were entirely rebuilt as Type 205 submarines.

    U3 was first commissioned for the Royal Norwegian Navy as a training boat, as Norway wanted to have fifteen boats of this type. Norway's coastal waters had no corrosive effect on the hull. In June 1964 the boat was handed back to Germany and was commissioned as a training boat.

Modernizations: None.

Naval service: No significant events.
