The Turkey Angle: Turkish Defence Industry
Spain is one of the most important naval partners of Turkey’s defence industry. The flagship and first aircraft-carrier of the Turkish Navy, TCG Anadolu, is based on Spanish Navantia’s Juan Carlos I design and was built in Istanbul under a co-production model with Sedef Shipyard.
The project shows Turkey’s ability to take a European design under licence and co-production and turn it into an original platform by integrating indigenous systems such as ASELSAN’s combat-management suite. TCG Anadolu has also added a distinctive Turkish signature by becoming the world’s first amphibious ship to operate drones.
Frequently Asked Questions
What is TCG Anadolu’s link to Spain? TCG Anadolu was built in Turkey based on the design of Spanish Navantia’s Juan Carlos I assault ship.
Does Spain have an aircraft carrier? The Juan Carlos I serves as both an assault ship and a light carrier able to operate Harriers/the F-35B.
What is Navantia? Spain’s state-owned main shipbuilding and naval-defence company.
Bottom Line
With a strong navy, balanced air elements and the Navantia-Airbus industry, Spain is an important actor on NATO’s Mediterranean-Atlantic axis. For Turkey it is a strategic naval partner — embodied by TCG Anadolu — demonstrating the success of the co-production model.
