The navy receives new fuel suppliers. The future “floating filling stations” of the Navy stand out clearly from their predecessors “Rhön” and “Spessart” (class 704) both visually and in terms of performance. They comply with the current guidelines (IMO, EU), according to which tankers must have a double hull. They also meet the NATO requirements that they are protected against NBC warfare agents. Your cargo volume should be around 12,000 cubic meters of aviation and diesel fuel. Up to three parallel refueling at sea should be feasible. In addition, the ships offer the possibility of placing modularly combinable container units, for example for workshops or spare parts stores, it is said.

The Bundeswehr has commissioned the Friedrich Lürssen shipyard in Bremen to build the two new fuel transporters for the German Navy. The new units, class designation 707, want to build the Lürssen shipyard together with the Meyer shipyard. The Rostock Neptun shipyard is to carry the lion's share of the program.

According to Tim Wagner, Managing Director of Fr. Lürssen Werft GmbH & Co. KG, the new fuel suppliers of class 707 will be equipped with a ballast water treatment system and a modern exhaust gas aftertreatment system to reduce emissions in accordance with IMO Tier III and thus comply with current environmental standards.

Compared to the originally formulated military requirements, the parameters have been changed significantly in two positions. The previously required speed of 20 knots has now become a maximum of 18 knots. The draft increases to 9.5 meters. This made it possible to orientate themselves towards more common designs.

The navy now has to deal with the stationing of the ships. The military requirement so far stipulated that the fuel transporters should remain at a draft of eight meters in order to avoid deepening the port at the Wilhelmshaven naval base.

The budget committee of the German Bundestag provided 914 million euros for the two fuel suppliers on June 23, 2021. Comparable units have unit costs of approx. 140 million euros - according to the Norwegian “Maud” - or approx. 210 million euros - according to the “Tide” class of the Royal Navy.
