National Combat Aircraft KAAN: Delivery Date, Indigenous Engine and 5th-Generation Features

One of Turkey’s most critical defense projects, the National Combat Aircraft KAAN, is being developed with the goal of becoming a 5th-generation fighter while its delivery schedule and indigenous-engine program also remain at the center of the agenda. So, when is the KAAN delivery date, what are the 5th-generation features, and what stage is the indigenous TF-35000 engine in? Here are the highlights.

KAAN Delivery Date: First Entry into Inventory in 2028

Developed by TUSAŞ, the National Combat Aircraft KAAN made its maiden flight on February 21, 2024. The second test flight was also successfully completed in 2024.

According to the project schedule:

• 2025-2027: Intensive flight tests and system verification
• 2028: First delivery to the Turkish Air Force (Block 10 configuration)
• 2030s: Full 5th-generation capability with advanced blocks

The Block 10 aircraft to be delivered initially are planned to have a configuration above the F-16 but below some advanced capabilities of the F-35. In later blocks, KAAN is targeted to fully meet 5th-generation standards.

5th-Generation Features: What Will KAAN Offer?

KAAN is designed around 5th-generation fighter features. Key capabilities include:

1. Stealth (Low Observability)

• Airframe design that reduces radar cross-section
• Internal weapon bays
• Use of radar-absorbing materials

2. Supercruise

• Supersonic flight without afterburner
• Sustained high-altitude operations

3. Sensor Fusion

• AESA radar
• Electronic warfare systems
• Infrared Search & Track systems
• Integration of all data into a single tactical display

4. Network-Centric Warfare

• Data sharing with UAVs and land/sea elements
• Multi-platform coordination

5. Internal Weapon Stations

• GÖKDOĞAN and BOZDOĞAN air-to-air missiles
• TOLUN and similar precision munitions
• Planned cruise-missile integration

KAAN Engine: F110 Transition and the Indigenous TF-35000

KAAN’s first prototypes and early blocks use the U.S.-origin F110 engine, which also powers F-16 fighters.

However, Turkey’s long-term goal is to develop a fully indigenous TF-35000 turbofan engine.

TF-35000 Engine Specifications (Target)

• 35,000 lbf thrust
• Supercruise support
• Low infrared signature
• High-temperature-resistant indigenous turbine technology

Integration of the engine into KAAN is targeted in Block 30. The introduction of the indigenous engine is considered a critical step that will reduce foreign-licensing restrictions on KAAN’s exports to third countries.

KAAN Export Target: Indonesia Agreement

The KAAN project is not aimed solely at domestic needs. The agreement between Turkey and Indonesia covers:

• 48 KAAN combat aircraft
• 10-year delivery timeline
• Technology transfer and joint-production options

This contract was recorded as one of the largest export agreements in the history of the Turkish defense industry.

KAAN Technical Specifications (Disclosed Data)

• Wingspan: 13.4 m
• Length: 20.3 m
• Max Speed: Mach 1.8
• Max Altitude: 55,000 ft
• Max Takeoff Weight: 34,750 kg
• Engine: Twin-engine configuration

Why is KAAN Strategic?

KAAN aims to:

• Put Turkey among the few countries developing 5th-gen fighters
• Enhance air-superiority capability
• Reduce foreign dependence in the defense industry
• Lay the groundwork for transition to 6th-generation concepts

Conclusion

The National Combat Aircraft KAAN, with its 2028 delivery target, TF-35000 indigenous-engine work and 5th-generation features, is one of Turkey’s most critical defense projects. As testing continues, the project remains closely watched both technically and geopolitically.
