Headquarters: Teknopark İstanbul

The company’s headquarters is at the Teknopark İstanbul campus in Pendik, on the Asian side of Istanbul. The listed address is Sanayi Mah. Teknopark Bulvarı No:1/4A, Pendik. This is the centre of the company’s engineering and R&D work, home to much of its workforce of more than 300 people, the majority of them engineers. Teknopark İstanbul is one of Turkey’s largest technology parks, which places the company alongside a wider cluster of technology and defence firms. It is from this campus that Altınay Defence has run the design and development of its product lines since being founded in 2014 within the Altınay Technology Group.

Altınay Defence's land systems are produced across its Istanbul and Kocaeli sites, which total more than 40,000 m2 of infrastructure. — Altınay Defence’s land systems are produced across its Istanbul and Kocaeli sites, which total more than 40,000 m2 of infrastructure.

Production: Kocaeli Dilovası

Manufacturing is concentrated at the Kocaeli Dilovası facility, which opened in December 2024. The listed address is OSB Mah. 6. Cadde No:1/1, in the Dilovası organised industrial zone. The 12,500 m2 plant provides dedicated production capacity for the company’s motion control, naval and weapon system products, separate from the engineering-focused Teknopark campus. Its opening was attended by the head of the Presidency of Defence Industries (SSB), underlining the plant’s place in national defence production. Placing serial production in an established industrial zone lets the company scale manufacturing while its Istanbul sites focus on design and development. The Dilovası zone, on the Kocaeli side of the Istanbul industrial corridor, is well connected to the wider manufacturing base in the region.

New campus: Tuzla

A third site, the Altınay Technology Campus, is under construction in the Tuzla Leather Organised Industrial Zone in Istanbul. Representing an investment of around 50 million US dollars, it covers 28,000 m2, split into roughly 16,000 m2 of R&D and 12,000 m2 of production, with groundwork begun in October 2025. Once complete it will significantly expand the company’s combined R&D and manufacturing footprint. The company has linked the campus to a plan for an R&D workforce of around 1,000 people, which would represent a large increase over its current headcount. Because the campus is still being built, it is best described as a future site rather than an operating factory, and its listed impact on production capacity will only materialise once it opens.

Total footprint

Taken together, these sites give Altınay Defence more than 40,000 m2 of total infrastructure, spanning production lines, storage and affiliate offices. The geographic spread, with Istanbul for headquarters and R&D, Kocaeli for production, and the new Tuzla campus, reflects the company’s growth alongside reported revenue that exceeded 3.1 billion TL in 2025. Note that there is no operating facility in Ankara; only a land-allocation application in the Ankara Aviation and Space Specialised Organised Industrial Zone exists there, and it remains at the planning stage. Anyone trying to locate the company’s factories should therefore focus on the Istanbul and Kocaeli region, where all current production and engineering activity is based, and use the specific site addresses above when planning a visit or delivery.
