|P340 Dogan, Dogan class|
The Turkish Navy nowadays (2015) has a fleet of 19 Fast Attack Craft (FAC), separated into four classes, the Kilic, Dogan, Ruzgar and Yildiz class. The last three and older classes are of same design and they are sharing similar technical characteristics and equipment among them. The boats are all manufactured in Turkey with the exception of the Dogan. The newest Kilic class will be analyzed in another article. The Dogan class is the oldest of the three classes as the boats have been built in the period 1976 to 1980. The vessels have a full displacement of 440 tons, a length of 58 meters and a very high speed of 38 knots. The vessels of Ruzgar class were built in the period 1984-1988 and they have a slightly shorter length (57 meters) and a displacement of 410tons. Sometimes the boats of Ruzgar class are considered as a sub-class of Dogan class or even belonging in the Dogan class. The reduced weight of Ruzgar class gives them also a greater speed of 41 (!) knots. The vessels of Yildiz class were built in the period 1994-1995 and they have similar features as those of Dogan class. The crew in the classes consists of around 40-45 people including 6 officers.

The armament completes two M2 12.7mm heavy machine guns, one at each side of the main mast, and two Raytheon FIM-92 Stinger mounts (one on Dogan/Ruzgar classes) amidships for point defense. The Stinger missile carries a high explosive annular blast fragmentation 3kg warhead in a range (effective) of more than 8 km.

The vessels of the Yildiz class are equipped with a Plessey AWS-6 Dolphin air and surface search radar, a Contraves TMX-CW fire control system, a Thales LIOD Mk2 electro-optical targeting and acquisition sensor system and a Kelvin Hughes KH1007 navigation radar. The AWS-6 Dolphin radar has an instrumented range (Surveillance Mode Performance) of 180km while the detection range exceeds the 110km (55km in the Defence Mode Performance). The track capacity is 200 air and sea targets. The TMX-CW is an X-band fire control radar that has a maximum tracking range of about 70km.
The combat management system is TACTICOS of Thales. In the equipment of Yildiz class are included a Target Designation Sight (TDS) that provides means for optical investigation, target designation and weapon firing. The TDS is equipped with binoculars and the latest version includes a Laser Range Finder. Bearing and elevation data are fed into the CMS system but the TDS can also be used for emergency control of a gun or CIWS system. The importance of the function of the TDS is re-emphasised against asymmetric tactics such as piracy and insurgency. Also Yildiz class features Cutlass 242 ESM (Cutlass B1) which is designed for operation in very dense signal environments; the systems receive signals in the 1 to 18 GHz frequency range, measure their parameters, compare these with those in a pre-programmed radar library and display the information within 1 second. In the equipment of the boats are also included Link 11 and Mk 36 SRBOC decoy launchers. The
purpose of the Mk36 system is to confuse hostile missile guidance and fire
control systems by creating false signals. The launching system is
controlled from the Combat Information Center and is dependent on
information provided by the detection and threat analysis equipment on
the ship. The Mk36 consists of the Mk137 launchers (two in Dogan, Ruzgar and Yildiz classes), the Mk158 Mods 1 and 2 master launcher control, the Mk164
Mods 1 and 2 bridge launcher control, the Mk160 Mod 1 power supply, the
Mk5 Mod 2 or Mk6 Mod 0 ready service lockers, and a range of munitions.
Each Mk 137 launcher has six 130-mm fixed tubes arranged in two
parallel rows at angles of 45 and 60 degrees. The firing circuits employ
electromagnetic induction to initiate the propelling charges in the
cartridges. Near each launcher is a deck locker with up to 20 Mk5 or 35
Mk6 rounds for quick reload.
