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]
