Gölcük Naval Base (Turkish language:Gölcük Deniz Ana Üssü) is the main base of the Turkish Navy on the east coast of the Sea of Marmara in Gölcük, Kocaeli. It is the principal base for logistic support with various facilities stretched over 1,800 acres (7.3 km2) of land.[1]

In addition to the workplaces, the base houses apartment-like barracks, social facilities, a military hospital, a military museum and an archive for naval history.[2]

The shipyard at the base is capable of constructing frigates, submarines, fast attack boats and auxiliary vessels with high technology in recognized standards.[2]


In the late 1920s, the area in Gölcük was chosen to build a floating drydock large enough to hold the Turkish battlecruiser TCG Yavuz for repair work of her war damage. Later, along with the German shipbuilding company Flender Werke that constructed the floating drydock, various repair shops, plants for the production of naval mine, torpedo and battery and housing barracks were built in Gölcük. In this manner, the need of drydocking of the TCG Yavuz paved the road Gölcük's to the naval base.[3]

These facilities were extended with various other buildings stretching over a big swampland, a small lake and hazelnut orchard fields in Gölcük. The Convention on the Turkish straits, part of the Treaty of Lausanne signed in 1923, banned military facilities in the Turkish Straits. So, Turkish Navy's infrastructure, like shipyards and naval facilities, at the Golden Horn and İstinye in Istanbul were systematically relocated to Gölcük. Main warships of the Turkish Navy, like battlecruisers, destroyers and torpedo boats, were then stationed in Gölcük.[3]

Finally, in 1933 the parliament enacted Gölcük as the main naval base of the Turkish Navy.[3]

1999 İzmit earthquakeEdit

The headquarters of the Battle Fleet Command in Gölcük, established in 1964, and many other buildings were heavily destroyed by the İzmit earthquake on August 17, 1999. The Command was temporarily housed in the Preveze War Games Center at the same base until July 2000, when the new headquarters building was completed.[2]

The earthquake cost the lives of 441 base personnel in total including 28 navy officers of various ranks, 136 warrant officers, one naval cadet, 39 civil officials, 9 corporals, 82 seamen and 126 workers.[4] Rear admiral Orhan Aydın, commander of the Turkish Naval Academy in Tuzla, Istanbul, was among the victims of the earthquake.[5]
