1. BRANDENBURG CLASS
FRIGATE (TYPE 123) –
SERVING GERMAN NAVY

2. INTRODUCTION
The Type 123 Brandenburg Class frigates were ordered in June 1989
to replace the Hamburg Class. The frigates are primarily tasked with
anti-submarine operations, but they also contribute to anti-air
defense, the tactical command of group forces and surface
operations. The ships form part of the Wilhelmshaven-based 6th
frigate squadron.
The Brandenburg has a displacement of 4,700t fully loaded and an
overall length of 138.9m. The ship has a maximum speed of 29kt
using the gas turbines and 18kt using the diesel engines, with a
range of 4,000nm at 18kt. The ship can accommodate 118 crew
(including 19 air crew).

4. COMMAND AND CONTROL
The combat data system is built around the Atlas Elektronik / Paramax SATIR
action data automation with Unysis UYK 43 computer, Link 11, and Astrium
(formerly Matra Marconi) SCOT 1A satellite communications. Weapons are
controlled by a Thales Nederland (formerly Signaal) MWCS system with two
optical sights.
The German Navy began a common upgrade programme for the combat
system on the four Brandenburg and eight Bremen Class (F122) frigates. A
contract was awarded to Thales in September 2005 to provide a new open
architecture system to replace the SATIR.
The upgrade was completed in 2011. IBM is supplied and installed the Link 16
capability enhancement and also installed the EADS defence electronics
multifunctional information distribution system (MIDS).

6. WEAPONS
The ship is armed with two twin launchers for MM38
Exocet surface-to-surface missiles, from MBDA (formerly
EADS Aerospatiale).
Exocet has inertial guidance with active radar homing and
a range of 42km. A Lockheed Martin mk41 mod 3 vertical
launch system for 16 NATO Sea Sparrow medium-range
surface-to-air missiles is fitted.
Sea Sparrow has semi-active radar terminal guidance and
a range of 14.5km.

8. COUNTERMEASURES
The electronic warfare suite includes the FL 1800 S-II
electronic support measures and countermeasures system,
developed by DaimlerChrysler Aerospace, now EADS
Systems & Defence Electronics. Two Oto Melara SCLAR
decoy dispensers are fitted for chaff and infrared flares.
The MASS decoy covers radar, infrared, electro-optic, laser
and ultraviolet wavebands. In June 2007, Rheinmetall was
contracted to supply MASS for the other three vessels, the
work to be completed by 2009.

10. SENSORS
The air / surface search radar is the Thales Nederland SMART 3D radar
operating at F band. Air search is performed by Thales Nederland LW08, D-band
radar. Two Thales Nederland STIR 180 tracking radars for fire control and two
Raytheon Redpath I-band for navigation are also fitted.
The Atlas Elektronik DSQS-23BZ hull-mounted medium-frequency search and
attack sonar is supplemented by a low-frequency active sonar system (LFASS)
towed array.
In March 2007, EADS Defence Electronics was contracted to supply the MSSR
2000 IFF Mode S information friend or foe (IFF) system for installation on
Schleswig-Holstein (F216) for the UNIFIL mission off Lebanon.
In November 2007, EADS received a contract to equip the other four
Brandenburg vessels with the system.

12. PROPULSION
The ship is powered by a CODOG (combined diesel or gas)
plant of two GE 2500 gas turbines, each rated at 33,600hp
with a power turbine speed of 3,600rpm, and two MTU
ZOV956 TB92 diesel engines, each developing 6,568hp at
1,500rpm, driving two shafts with controllable-pitch
propellers.
