PTB is a defence industry company established through the partnership of three strong shipyards — Park, Turkter, and Besiktas — each with significant accumulated expertise in Türkiye's shipbuilding and ship maintenance & repair sector.
The company's core mission is to consolidate existing shipyard infrastructures under a single corporate structure, delivering scalable production, centralized programme management, standardized quality, and a reliable delivery model — particularly for defence programs.
Within Türkiye's evolving naval defence shipbuilding ecosystem, PTB operates a multi-shipyard model supported by centralized integration, offering a structured alternative to the traditional single-shipyard approach.
