Turkish Aerospace Industries (TAI) Presented New Prototypes of the Fifth-Generation KAAN Fighter Jet on February 13, 2026

On February 13, 2026, Turkish Aerospace Industries (TAI) publicly released a video showcasing new prototypes of their 5th generation KAAN stealth fighter jet. the original prototype P0, which made its maiden flight on February 21, 2024, is seen in the center.  It is flanked by Prototypes P1 and P2, still coated in factory primer. Prototype number P1 is shown on the right side of the image and shows a number of design changes from P0. A nearly complete prototype P2, still missing its engines, nose sensors, radar, and nose cone is shown of the left side of the image.

The design changes, highlighted in red in the above photo collage, are as follows:

• Redesigned Aft Fuselage Section: It has a more flush, and hence stealthier, profile between the two engines. This change will most likely help increase the aircraft's fuel capacity.
• Air Intakes: The engine intakes on P1 are positioned further back in relation to the cockpit compared to P0.
• Redesigned Flaps: The flaps on the trailing edge of P1's wing now have a uniform edge line in comparison to P0, which had larger inboard flaps than outboard flaps.
• Redesigned Horizontal Tailplanes: A slight adjustment was made on P1 that clipped the inside corners of the horizontal tailplanes. A similar adjustment was made on the American YF-22/F-22 when it was in development.
• New IRST/EOTS Sensors: P1 now shows an Infrared Search and Track (IRST) sensor on the dorsal side of the aircraft's nose just ahead of of the cockpit canopy. An Electro-Optical Targeting System (EOTS) is shown in a mounting on the ventral side of the nose.
