KAAN Fighter Jet: Development, First Flights, Specs and Program Status

KAAN is Türkiye’s indigenous next-generation fighter development program. Turkish Aerospace Industries (TUSAŞ) leads the aircraft project for the Presidency of Defence Industries (SSB), with the long-term objective of replacing Turkish Air Force F-16s as they are gradually retired from the 2030s.

KAAN has flown, but it is not yet an operational combat aircraft. The first engineering prototype completed its maiden flight on February 21, 2024 and a second test flight on May 6, 2024. Manufacturer specifications and intended capabilities describe the design goal; they should not be confused with capabilities already validated across a completed flight-test and certification program.

KAAN fighter program at a glance

What is the KAAN fighter?

KAAN grew from Türkiye’s Milli Muharip Uçak, or National Combat Aircraft, effort. The program is intended to create domestic capability not only to assemble an aircraft, but also to design, integrate, test, certify, maintain and sustain a modern fighter over its service life.

According to the official Turkish Aerospace KAAN program page, the development agreement with SSB was signed in 2016. The stated objective is to provide a domestically designed fighter as Turkish Air Force F-16 aircraft are phased out beginning in the 2030s.

TUSAŞ markets KAAN as a fifth-generation multirole design. The planned feature set includes low observability, internal weapon bays, sensor fusion, advanced mission systems, high maneuverability and interoperability with other air, land and maritime assets.

KAAN development timeline

2016: program agreement

The formal development project agreement was signed on August 5, 2016. Early work covered preliminary design, aerodynamic development, engineering infrastructure, test capability and certification planning. These foundations are as important as the visible prototype because a combat aircraft requires a repeatable production and support system, not only one flying airframe.

2023: prototype rollout

The engineering development prototype was publicly rolled out in March 2023. Rollout meant that the assembled aircraft could proceed into ground testing; it did not mean the fighter was complete or combat-ready. Ground activity precedes flight and can include structural checks, systems integration, engine runs, taxi tests and progressive validation of aircraft behavior.

February 2024: maiden flight

KAAN’s first flight took place on February 21, 2024. TUSAŞ reports that the aircraft remained airborne for 13 minutes, reached 8,000 feet and attained 230 knots. An F-16 accompanied the prototype. A first flight is intentionally conservative: the objective is to confirm basic operation and gather data, not demonstrate the full advertised performance envelope.

May 2024: second test flight

The second reported flight occurred on May 6, 2024. It lasted 14 minutes, reached 10,000 feet and again reached 230 knots. These two flights established that the prototype could take off, operate within the tested envelope and land, but they represent an early stage in the much larger test campaign required for a modern fighter.

KAAN dimensions and manufacturer specifications

TUSAŞ publishes the following design data. These figures are manufacturer targets or specifications and not an independent operational evaluation:

Numbers on a manufacturer page can change as the design matures. Prototype configuration, production configuration and export configuration may differ. Combat radius, radar signature, payload and sustained performance cannot be inferred accurately from basic dimensions alone.

Why KAAN uses a twin-engine layout

The published KAAN design uses two afterburning turbofan engines. A twin-engine arrangement can provide the thrust needed for a large fighter carrying fuel, sensors and weapons internally while pursuing high speed and maneuverability. It also affects inlet design, internal volume, maintenance, cost and infrared signature.

The long-term powerplant strategy is a major program variable. Türkiye is developing domestic turbine-engine technology, but smaller demonstrators such as the TF6000 should not be mislabeled as the operational KAAN engine. SSB describes TF6000 as a technology and capability step on the road toward a national fighter engine, not as a drop-in engine for the full-size KAAN.

Engine selection, integration, production rights and the transition to any future domestic powerplant will influence schedule and configuration. Until the responsible program authorities announce and demonstrate a production standard, claims about a final engine should be treated cautiously.

Low observability and internal weapons

Low observability is a system-level goal rather than a single shape feature. KAAN’s planform uses aligned edges, canted tails and internal weapon bays consistent with reducing radar reflections. Materials, panel joints, apertures, inlet treatment, coatings, thermal management and maintenance quality also influence the result.

TUSAŞ lists low radar and infrared signature among the program goals. No public official source provides a complete, independently verified radar cross-section across frequencies and aspects. Calling KAAN a stealth-oriented design is supported; assigning it an exact stealth ranking is not.

Internal carriage helps preserve a cleaner external shape and can reduce drag and radar signature during selected missions. External stores may increase payload or flexibility but change both aerodynamic and signature performance. The practical balance will depend on mission planning and the weapons certified for each configuration.

Avionics, sensors and pilot interface

The program describes an integrated mission system combining radar, electronic warfare, electro-optical, communications, navigation and identification functions. Sensor fusion is intended to combine multiple inputs into a more usable tactical picture rather than force the pilot to interpret each sensor independently.

TUSAŞ also lists a large-area cockpit display, helmet-mounted display, integrated processing and decision-support features. These are intended capabilities. Their effectiveness depends on hardware maturity, software integration, human-factors testing, electronic protection, data quality and extensive operational evaluation.

References to artificial intelligence and neural networks should be read in that context. Marketing terminology does not establish autonomous combat decision-making. The published concept emphasizes pilot decision support, target recognition and workload reduction within a crewed fighter.

Weapons and mission roles

KAAN is planned for air-to-air and air-to-ground missions. TUSAŞ highlights beyond-visual-range and within-visual-range missile employment, precision strike and internal weapon carriage. Actual combat capability will depend on which Turkish or foreign weapons complete separation, integration and certification testing.

A weapon that physically fits a bay is not automatically operational. Safe carriage requires structural, electrical, software, environmental and separation work. Published renderings and exhibition models should therefore not be treated as proof that every depicted weapon is certified.

Is KAAN operational?

No. KAAN is a flying development program, not an operational squadron aircraft. The official evidence establishes early prototype flights. It does not establish completed development testing, production certification, combat readiness or fielded Turkish Air Force units.

An SSB sector strategy published a planning objective of entering inventory in 2028. That is a program target, not a guaranteed service date. Fighter schedules can move as prototypes uncover design changes, suppliers deliver subsystems, software matures and certification evidence accumulates.

Readers should distinguish four milestones:

1. Prototype flight: an engineering aircraft begins flight testing.
2. Production decision: authorities authorize and fund a defined batch or configuration.
3. Delivery: an air force accepts an aircraft, potentially for further testing or training.
4. Operational capability: trained units can perform assigned missions with supported aircraft and weapons.

Why the program matters

KAAN’s significance extends beyond one airframe. The program is intended to expand Turkish capability in aerodynamics, structures, systems integration, mission software, sensors, flight testing, certification, manufacturing and lifecycle support. Even when individual components are imported, integrating them into a reliable combat system requires substantial domestic engineering.

The project also sits within a broader Turkish aerospace portfolio that includes HÜRJET, unmanned combat aircraft, helicopters and upgrades to existing platforms. Shared suppliers and technical experience can strengthen the industrial base, though each program has distinct requirements and schedules.

Common KAAN fighter misconceptions

• “KAAN was a mid-20th-century fighter.” False. The real program agreement dates to 2016 and its first prototype flew in 2024.
• “KAAN is already in combat service.” False. It remains in development and test.
• “The first flight proved Mach 1.8 performance.” False. The maiden flight reached 230 knots; Mach 1.8 is a published design target.
• “Fifth generation is a completed certification.” Misleading. TUSAŞ classifies the design that way, but the intended low-observable, sensor-fusion and combat capabilities must mature through testing.
• “TF6000 is KAAN’s production engine.” False. SSB describes TF6000 as a technology step toward a national fighter engine.

Bottom line

KAAN is a real, flying Turkish next-generation fighter project led by TUSAŞ—not a fictional historic aircraft and not yet an operational fifth-generation fleet. Its 2024 prototype flights were important milestones, while its speed, stealth, avionics, weapons and service schedule remain development objectives that must be demonstrated progressively.
