The auxiliary ships of the Wangerooge class (officially: Class 722 ) are sea tugs of the German Navy . Their main task is to tow and recover vessels and to provide assistance at sea. The towing of targets and the recovery of exercise torpedoes and mines is another task of the sea tugs.

General

As part of the shipbuilding program of 1960, Schichau Unterweser AG in Bremerhaven received the order to build six class 722 sea tugs. They have a steel hull with a Maier shape and ice reinforcement , which is divided into VIII departments. The superstructures are made of light metal and there is NBC protection.

All units in this class were given names from the East Frisian Islands and have or had civilian occupation.

With the exception of the Spiekeroog , all sea tugs were decommissioned and put up again after a short time due to the reduction in personnel in the Navy as part of a structural change.

Two of the units were later put back into service as sea tugs. The other three were converted into school boats.

As part of retrofitting and retrofitting, the sea tugs were later reclassified: Wangerooge - 722C, Spiekeroog - 722B and Norderney - 722B1.

units

722/01 Wangerooge (since 1968)

The Wangerooge was put into service on April 8, 1968 for the 2nd supply squadron . The home base was Wilhelmshaven . As early as October 31, 1969, she was decommissioned in the Naval Arsenal , then mothballed and placed under the reserve flotilla. On July 1, 1970, the Wangerooge was put back into service for the 2nd supply squadron in Wilhelmshaven. With the amalgamation of the 1st and 2nd supply squadrons to form the Trossgeschwader on March 25, 1997 nothing changed for the Wangerooge , it remained stationed in Wilhelmshaven.

A standard task for the Wangerooge is the support of the naval operation school with "survival training at sea" (Open Sea Survival Training). Here, under real conditions in wind and rough seas, aircraft crews practice jumping from the stern of the tug into open water and then rescuing them on the life raft.

On December 19, 1989 , the Wangerooge was the first unit with a civilian crew to receive the so-called “Nikolauspreis” of the ship safety teaching group in Neustadt in Holstein as the best annual achievement in ship safety training.

722/02 Spiekeroog (since 1968)

On August 14, 1968, the Spiekeroog and the Langeoog were put into service together for the 1st supply squadron. They were stationed at the naval base in Kiel . The amalgamation of the 1st and 2nd supply squadrons to form the Trossgeschwader on March 25, 1997 changed nothing for the Spiekeroog , it remained stationed in Kiel. At times, the Spiekeroog was / will be parked for security tasks with the 1st and 3rd submarine squadrons .

Remarks

↑ The technical term (in) cocooning used in the navy includes the preservation and (airtight) sealing of a device or even an entire ship. In shipping, a ship that has been taken out of service is called a trailer . Colloquially, this process is also called "mothballing".
