Milgem ‘In a class of her own!’

First ship of the Milgem project, TCG Heybeliada, during sea trials.

Along the 8,300 km coastline of the Turkish Republic the Turkish Navy ensures the safety of the country’s waterways and protects its territorial waters and exclusive economic zone. Since the region is frequently struck by earthquakes, the Navy must also be prepared for humanitarian operations; and it also participating in numerous stabilisation and peacekeeping missions on an international scale, for example off the coast of Somalia and in the Gulf of Aden. The Turkish fleet undergoes continuous modernisation so as to be ready for any eventuality.

(F-511) was launched on September 27, 2008 in Istanbul Naval Shipyard at a ceremony in which all eyes were focused on this remarkable ship. With her compact design and stealthy look, the corvette gives a good impression of what she will be able to achieve in operation. HEYBELİADA (F-511) is the lead ship of a class that has been designed, built and outfitted with maximum local content, and as such is the pride of the crew.

MİLGEM-Class Corvettes are designed for operation in littoral waters and are furnished with many signature-reducing measures, which make the vessel hard to detect. It is equipped with Turkey’s most sophisticated platform and combat systems, weapons and sensors, and as such is one of the most modern vessels in its class worldwide. Turkish PrimeMinister Recep Tayyip Erdoğan insisted on launching the lead ship personally during a ceremony.

CODAG: More than 30,000 kW

The centrepiece of the vessel, with a specified top speed of 29 kts, is a CODAG type propulsion system (Combined Diesel and Gas Turbine) supplied by MTU. Two 16V 595 engines with a power output of 4,320 kW each (5,875 hp) and a 23,000 kW (31,280 hp) LM 2500 gas turbine provide power to two controllable-pitch (CPP) propellers via a Renk gearbox, ensuring the reliable operation of the corvette. While the two diesel engines provide power for cruising during regular patrols, the switch-in of the gas turbine enables the vessel to fulfil its high speed requirements. The CODAG propulsion system is controlled and monitored by an MTU Callosum MC automation system.

A long tradition of MTU Engines

Since the first German vessels with Maybach andMercedes-Benz engines were supplied to Turkey in 1967, a large proportion of the ships and submarines used by the Turkish Navy and other governmental authorities, such as the coast guard, have been equipped with MTU power systems. These include both mine layers and mine sweepers of the Aydın class (Lead ship “Alanya”), with two MTU 8V 396 TB84 diesel engines each; Kılıç patrol boats; and the new 1,700 tonne search and rescue vessels of the coastguard, which feature Series 1163 main propulsion systems.

Moreover, two MTU 16V 4000 M70 diesel engines, each with a total power output of 4,640 kW (6,310 hp), will be installed on the landing craft currently under construction at the Turkish ADİK shipyard in Istanbul, being built for the transportation of tanks and vehicles (LCT’s). These landing craft are destined to transport troops and technical equipment by sea to their operating site, to safeguard supplies, and to land tanks and other vehicles at inaccessible coastal areas. In support of humanitarian missions, they can also transport urgently needed supplies and equipment for clearance, such as excavators and bulldozers.

The technical training of the crew, and the maintenance and logistic support for the propulsion systems will be provided by MTU Turkey.
