The ships were built at Flensburger Schiffbau-Gesellschaft in Flensburg.

All ships are currently based in Eckernförde and belong to the 1st Ubootgeschwader (1st Submarine Squadron) stationed in Eckernförde. The vessels received the same name and pennant numbers as the three Type 422 class vessels they replaced. To avoid the confusion, the ship names are sometimes suffixed with II.

Oker (A53) was reportedly spotted near the Syrian coast in August 2012.[2] Later she was seen in Greenwich, UK in February 2017[3]
