KIZILELMA starts flight tests with ASELSAN’s KARAT IRST: what changes with passive sensing?

Baykar’s KIZILELMA has started flight tests with ASELSAN’s KARAT IRST (Infrared Search and Track) system, marking a shift from “platform performance” headlines to “combat-relevant sensing” integration. In other words, it’s not only about flying and autonomy anymore—it's about how the aircraft perceives, tracks, and contributes to an air-combat picture.

What is IRST, in simple terms?
IRST systems are designed to detect and track targets passively using infrared signatures—without emitting radar energy. Radar searches by transmitting and receiving reflections; IRST “looks” for heat-based cues. That distinction matters because passive sensing can add options in scenarios where emissions, electronic warfare, and survivability are part of the equation.

Does IRST replace radar?
Typically, no. The value of IRST is strongest when combined with other sensors. Modern air combat increasingly depends on sensor fusion: combining radar, IRST, electro-optics and datalink inputs into a single track picture. So the real question behind “KIZILELMA with KARAT IRST” is not just whether the sensor is mounted, but how deeply it is integrated into mission computing and tactical workflows.

Why is KARAT noteworthy?
KARAT is positioned as an IRST solution for combat aircraft (manned and unmanned). In IRST logic, core themes include passive search/detection/tracking, wide-area scanning and multi-target tracking. Pairing that sensor class with an unmanned jet platform suggests an intent to grow beyond strike-only assumptions and toward roles that require richer situational awareness.

What does “passive detection” realistically add?

• It can reduce reliance on active emissions in certain phases of an engagement.
• It provides an additional sensing channel when electronic attack pressures radar performance.
• Under specific conditions, it may help cue or maintain tracks on targets that are challenging in other bands.
  These are scenario-dependent advantages, not guarantees—so testing and integration are where the truth is established.

What should be watched next?
1) Air-target tracking profiles: are there clearer scenarios demonstrating air track generation and continuity?
2) Fusion maturity: is IRST data fused into the mission system in a tactically useful way?
3) Sharing: can passive tracks be shared across the package via datalinks?
4) Concept of operations: does it point toward independent “fighter-like” roles or stronger manned-unmanned teaming?

Mini FAQ

• What does IRST stand for?
  Infrared Search and Track.
• Radar vs IRST: what’s the key difference?
  Radar emits; IRST is passive and relies on infrared signatures.
• Does this mean full air-to-air capability today?
  Not by itself. But it is a meaningful step toward the sensing layer required for air-combat roles.

Bottom line: Bringing KARAT into flight tests is a “seeing” milestone, not just a “flying” milestone. The next chapters will be about fusion, sharing, and how this sensing capability shapes real mission profiles.
