Design and development
KTJ-3200 engine has begun to be developed to replace the French Microturbo TRI-40 jet engines used in the SOM missiles developed by Tübitak Sage. The first test was conducted in 2018.[3][4] The process was accelerated after France created difficulties in the sale of jet engines to Turkey.[5] The first batch of KTJ-3200 engines was delivered to Roketsan on 21 November 2020.[6] It was announced that the first mass production KTJ-3200 engines were delivered to Roketsan in the first quarter of 2022.[7] On 10 March 2024, the KTJ-3200 engine was installed on the Atmaca missile and the first test launch was successfully made.[8] On 4 April 2025, a contract was signed between Kale Group and the Brazilian company SIATT for the use of KTJ-3200 in MANSUP anti-ship missiles.[9][10]
