The THK-5 was a twin-engine aircraft developed in Turkey in 1945 as an air ambulance. It was a conventional, low-wing cantilever monoplane of wooden construction throughout. The main units of the tailwheel undercarriage retracted into the wing-mounted engine nacelles and the THK-5 could carry two stretcher cases plus a medical attendant. This was followed in production by a six-seat utility transport version designated THK-5A and three examples of an improved version of the 5A designated THK-10. A single example of the type was exported, sold to Denmark.
When THK was taken over by MKEK, this was one of the designs selected for further work. However, although the designation MKEK-5 was allocated, nothing further came of this.

Performance
The THK-2 was a single-seat, single-engine aerobatic trainer aircraft developed in Turkey in 1944 intended as an advanced trainer. It was a conventional, low-wing cantilever monoplane with an elliptical planform and of wooden construction. The cockpit was enclosed and the main units of the tailwheel undercarriage retracted backwards into the wing.
Designed by Polish engineers who had come to Turkey to help establish the Türk Hava Kurumu factory, the first prototype flew in 1944 and the second flew the following year. This led to production in series, but only four further examples were built before the project was abandoned. When THK was taken over by MKEK, this was one of the designs selected for further work. However, although the designation MKEK-2 was allocated, nothing further came of this. The THK-2s were used by the Turkish Air Force in their intended role until the mid-1950s.
