The Type 103 Lütjens class was the last class of destroyers in service with the German Navy. They were replaced by the new Sachsen-class frigates, designated frigate even though they are much larger and more capable in all aspects than the Lütjens-class destroyers. Basically the ships were Charles F. Adams-class guided missile destroyers but with some modifications to meet German requirements:

Communication systems according to German standards. The Lütjens class had more aerials and a second mast mounted on the aft funnel, the large air surveillance radar was positioned further aft (above the funnel).
Different funnel design. This was necessary because of the new antennas and radar location. On the Lütjens the exhaust gases were emitted sideways with two pipes on the port and starboard side of each funnel.
New location of the sonar array: The Lütjens had its sonar dome located in a bulge directed forward in the bow and not under the bow to reduce the ship's draft.
Better crew accommodations.

The Lütjens class was upgraded to Type 103A in the 1970s with new digital fire-control computers and better missiles for the old Tartar SM1 missile system. The boilers were also converted to burn lighter oil for logistical reasons instead of the heavy fuel oil that needs to be preheated.

A second major refit began in the 1980s, with new fire control computers and radar for the guns.

In the 1990s, the ships in the class each received two RAM launchers and Chaff launchers.

With the decommissioning of Lütjens (D185) on December 18, 2003 the age of steam ended for the German Navy. Mölders (D186) became a Museum Ship at the German Navy Museum in Wilhelmshaven.

Note: Speeds over 30 kn could only sustained for a limited time due to the enormous fuel consumption. With two active boilers the ship could achieve speeds up to 27 kn. Three boilers made 30 kn achievable. For any speed beyond 30 kn all four boilers were needed.

List of ships

Pennant number	Name	Call sign	Commissioned	Decom- missioned	Fate
D185	Lütjens	DRAE	March 22, 1969	December 18, 2003	2012 scrapped in Aliaga, Turkey
D186	Mölders	DRAF	September 20, 1969	May 28, 2003	Museum ship in Wilhelmshaven
D187	Rommel	DRAG	May 20, 1970	September 30, 1998	cannibalized, 2004 scrapped in Turkey

All three ships were built by Bath Iron Works in the United States. They were named after famous German officers who died in World War II. In service, they formed the 1. Zerstörergeschwader (first destroyer squadron) and were based in Kiel.
