Sachsen-class Frigate

The F124 Sachsen-class is Germany's latest class of highly advanced air-defense frigates. The design of the Sachsen-class frigate is based on that of the F123 Brandenburg-class but with enhanced stealth features intended to deceive any opponent's radar and acoustic sensors and incorporate also the advanced multifunction radar APAR as well as the SMART-L long-range radar which is claimed to be capable of detecting stealth aircraft and stealth missiles. Although designated as frigates, they are in capability and size comparable to destroyers.

At €2.8 billion for only four ships, this was one of the most expensive ship building programs of the German Navy. They are similar to the Dutch De Zeven Provinciën-class frigates. Both the Sachsen-class and the De Zeven Provinciën-class frigates are based on the use of a common primary anti-air warfare system built around the APAR and SMART-L radars and the area-defence SM-2 Block IIIA and point-defence Evolved Sea Sparrow Missile (ESSM) surface-to-air missiles.

In June 1996 the German government contracted for three ships with an option on a fourth that was provisionally to have been named as the BMS Thüringen, which was taken up in February 2002.

The F124-class frigates are larger and much more capable in all aspects than the Lütjens-class destroyers, which they replaced.
