Design and development
On 8 November 2018, an agreement was signed between the Turkish Defense Industry Presidency and TRMOTOR to develop a domestic engine for TAI TF Kaan. In 2021, TEI and TRMOTOR decided to form a partnership in engine development.The status of the studies for the production of a Turkish-made engine for KAAN was announced with the introduction of the TEI-TF6000 engine. It was stated that the TF-6000 and the TF-10000 engine developed in parallel with it were preliminary preparations for a more powerful and larger engine. On 15 May 2025, both TEI and TRMOTOR announced the TF35000 engine on their websites and showed the design of the engine for the first time.
TEI CEO, who attended the Paris Air Show on June 23, 2025, stated that they have been working on the design of the engine for a long time and have reached the end of the design phase. He continued his statement by saying that the first prototype production is planned for the end of 2025, the first tests in 2026 and the integration into Kaan in 2032. TEI CEO Akşit announced at a trade fair he attended in September 2025 that the TF-35000 will not be a large-scale copy of the TF-10000, but will be a fifth-generation fighter jet engine incorporating new technologies.
