1000th production of KTJ turbojet engines

KTJ turbojet engines produced by Kale Jet Engines have reached the production level of 1000 units. First of all, the production of the 1000th engine was completed within the scope of national engine works under the coordination of the Presidency of Defense Industries (SSB). In addition, thanks to domestic production, at least 200 million dollars of resources remained in Türkiye.

This success was celebrated with a ceremony held at SSB. Additionally, President of Defense Industries Prof. Dr. Haluk Görgün also attended the ceremony. Görgün said that the process from the first engine to the 1000th engine showed Türkiye's engineering know-how.

Görgün also said: "Today, we are proud to deliver the thousandth engine of Kale Jet Engines. Developing the first engine is a great engineering success. Being able to produce and deliver it a thousand times with the same quality is an industrial success in itself."

What did KTJ turbojet engines bring to the economy?

Görgün said that the transformation, which started with decisions based on domestic development and production in 2004, has yielded results. He also reminded that the rate of localization in the defense industry increased from 20 percent to 83 percent.

Regarding the figures, Görgün said: "With these thousand engines, we have ensured that at least 200 million dollars of resources remain in our country. We are in a period where mass production is increasing, so this figure will go much higher." Moreover, the increased capacity supports the knowledge of Turkish engineers and the production power of domestic suppliers. For this reason, new investments are also gaining momentum.

Which missiles fly with domestic engines?

Kale Jet Engines started its domestic turbojet engine work in 2013. We have previously reported the company's new engine calendar. Today, three different engines are in mass production. In addition, these engines power national missile systems.

KTJ-3200: Used in SOM Cruise Missile and ATMACA Anti-Ship Missile. It was also qualified and put into mass production in 2021.

KTJ-1750: It also powers the ÇAKIR Cruise Missile.

KTJ-3700: Also used in the BLACK ATMACA Cruise Missile.

Thus, KTJ-3200 entered the inventory of the Turkish Air Force with SOM and the Turkish Naval Forces with ATMACA. However, KTJ-1750 and KTJ-3700 are aimed to enter the Turkish Armed Forces inventory together with the relevant missiles.

Export and cooperation

The KTJ-3200 turbojet engine was also exported to Brazil in 2025. Thus, Türkiye realized the first jet engine export in its history.

According to Görgün, this success was made possible by inter-institutional cooperation. Because, under the coordination of the SSB, Kale Jet Engines, ROKETSAN, TÜBİTAK SAGE, domestic suppliers and the Turkish Armed Forces are working for common goals. In addition, "As production grows, this entire ecosystem develops." Görgün stated that this structure also contributes to international competitiveness.

The next goal is to develop new engines and increase mass production capacity. Görgün also said that it is planned to move national engine technologies further with the contribution of young engineers.
