The ships carry fuel, fresh water, food, ammunition and other matériel. They also have a medical station aboard but doctors are not part of their standard complement and will have to be flown in. The tender also manage waste disposal for the ships they support at sea and can carry out minor repairs of assigned ships. For this purpose Elbe-class tenders assigned to fast attack craft squadrons, for example, carry the SUG repair and support shop specialized for these boats on their deck in a set of 13 standard containers.

Extensive communication gear and accommodations enable them to serve as squadron flagship.

While in general all Elbe-class tenders are quickly configurable to be reassigned to support other squadrons, one of the six ships is usually modified to support German submarines - carrying batteries for reloading for example. This ship - currently Main - while still being of the same class, and easily reconfigurable - is often named as a separate "sub-class" due to this larger modification.
