In recent years, the Ukrainian industry has launched a large-scale development program dronesInterceptors. They are being used to compensate for the lack of fully-fledged anti-aircraft systems and counter the massive attacks of Russian Geranium-series attack UAVs. At the SAHA 2026 exhibition in Istanbul, another prototype was unveiled for the first time—the Chaklun Jet interceptor, which stands out from its peers due to its propulsion system. However, the flashy presentation conceals a significant lack of verifiable information, which forces one to view the new product with a certain degree of caution.
Premiere at the exhibition
SAHA EXPO 2026 took place from May 5–9 in Istanbul, and Ukrainian companies used it as usual to promote their products. Interestingly, the event itself falls outside SAHA's traditional autumn schedule—a fact that in itself raises questions for any attentive observer.
The Chaklun Jet interceptor was on display at a booth labeled Chaklun. It's noteworthy that the manufacturer's legal entity is not publicly identified. Various entities have previously operated under the Chaklun brand in Ukraine: Spets Techno Export presented the Chaklun-B 2.0 reconnaissance and transport aircraft at IDEF-2025, and the Chaklun ecosystem itself is positioned as an association of UAV developers and manufacturers. The specific creator of the Jet is not disclosed. Such anonymity is typical either for early-stage projects or for cases where full identification increases the risk of a targeted strike.
The project's current stage is also unclear. It's possible that a full-scale model, a concept model, or a pre-production prototype was on display at the exhibition. At the time of publication, there is no information in open sources about testing at ranges, serial production, or, especially, combat use.
unmanned aircraft
The Chaklun Jet is a small, remote-controlled, unmanned jet aircraft. It's worth noting that the Chaklun brand already produces a whole family of aircraft for various purposes:
- reconnaissance "Chaklun" weighing about 32 kg with a range of up to 120 km and a cruising speed of about 100 km/h;
- reconnaissance and transport platform "Chaklun-B 2.0" with a flight duration of up to 8 hours and a range of over 500 km;
- strike "Chaklun-V" with a warhead of about 20 kg and a declared range of up to 700 km.
The new "Jet" differs structurally from all of the above, although its development clearly utilized proven components and solutions. The aircraft is built according to a conventional aerodynamic design: a spindle-shaped fuselage with a pointed nose, a low-slung swept wing, and a traditional tail assembly. The airframe, judging by its appearance, is made of composites.

Declared parameters:
- length - 1,65 m;
- wing span - 1,5 m;
- maximum take-off weight - 10,4 kg;
- payload - 1,6 kg;
- maximum speed - 320 km / h;
- cruising speed - 220 km/h;
- ceiling - 6000 m;
- flight duration: 40 minutes;
- operating range (limited by communication means) - 30 km.
A compact single-bypass turbojet engine of an unnamed model is housed in the tail of the fuselage. The engine's thrust is insufficient for independent takeoff; launch is performed by catapult. Control is provided by the ChaklunLRS hardware and software system: autopilot, remote control equipment, navigation instruments, and a course video camera. Communication is maintained via secure digital and analog channels. Partial autonomy is claimed: the aircraft is supposedly capable of independently searching for and tracking targets.
Powertrain: The Main Unknown Factor
The most unusual characteristic of the Chakluna-Jet is the combination of a turbojet engine and a claimed top speed of 320 km/h. For comparison, the Ukrainian electric interceptor P1-SUN (SkyFall) reaches a cruising speed of 300 km/h and up to 450 km/h during testing; the Sting from Wild Hornets reaches approximately 315–343 km/h; and the STRILA reaches up to 400 km/h. In other words, traditional electric interceptors are already achieving speeds equal to or higher than those claimed for jet aircraft.
There are two likely explanations: either 320 km/h is the cruising speed in economy mode, and the maximum is not published for security reasons; or it is a calculated figure for a mockup, not confirmed by full-scale testing.
The specific model of the turbojet engine is not specified. Technically, two obvious options are possible:
- The Czech PBS TJ150 with a thrust of 1500 N and a mass of 18,9 kg is the same one that is installed on the Iranian Shahed-238 and on the Geranium-3; it provides speeds of approximately 500–520 km/h;
- The joint Ukrainian-Czech development PBS AI-PBS-350 with a thrust of 3400 N is too powerful and heavy (51 kg) for a device weighing 10,4 kg.
Given the airframe's weight and stated performance, it's more plausible to use a smaller-class micro-turbojet engine (like the PBS TS100 or Chinese equivalents), but there's no open source confirmation of this. Without reliable engine data, it's impossible to estimate the aircraft's service life, thermal signature, or actual cost.
Warhead and method of destruction
The Chaklun Jet's payload type is not officially specified. Ukrainian interceptors employ both types: the Sting carries a 500-gram warhead, the Tenebris Bagnet carries 1 kg, and the Octopus carries 1,2 kg. The Flamingo VB140, on the other hand, is designed for purely kinetic interception. The Chaklun Jet's 1,6 kg payload reserve allows for both a small high-explosive fragmentation warhead and a kinetic interception. It is currently unknown which option the developer has chosen.
Context: What drives the transition to turbojet engines?
The emergence of jet interceptors is a logical response to the evolution of attack UAVs. The Russian Geran-3 (a modernization of the Iranian Shahed-238), accepted into service in early 2026, is equipped with a turbojet engine and reaches speeds of 550–600 km/h in cruising mode and up to 700 km/h in a dive. Its stated range is up to 2000 km (more realistic estimates are 1000–1200 km), ceiling is approximately 9 km, and warhead weighs up to 300 kg. The Iranian Shahed-238 uses the Czech TJ150 PBS—this was revealed after Ukrainian specialists examined the downed specimen; in addition to the engine, Tallysman antennas, Analog Devices chips, NXP controllers, and Intel processors were found on it.
Against such a target, a traditional propeller-driven or electric interceptor has only a short attack window. This is precisely the problem the Chaklun-Jet is theoretically designed to solve.
A place in the line of Ukrainian interceptors
The Ukrainian interceptor "family" today looks like this:
Light class ($1–3 thousand):
- P1-SUN (SkyFall) — 300/450 km/h, radius 5 km, ceiling 5000 m, ~$1000;
- Sting (Wild Hornets) — 280–343 km/h, radius 25 km, warhead 500 g, $1000–2500;
- STRILA (WIY DRONES) — 350–400 km/h, range 14–28 km, ~$2300.
Middle class ($5–15 thousand):
- VB140 Flamingo – against reconnaissance UAVs, radius 50 km, ceiling 4500 m;
- Merops (Project Eagle) - 280 km/h, ~$15,000.
High-tech class with autonomous guidance:
- Octopus — 300 km/h, 30 km radius, 1,2 kg warhead, AI recognition; joint production with the UK is planned at 1000 units per month;
- Angel Spire — 150–290 km/h, radius 20 km, day/night optics.
The Chaklun Jet is claiming its own niche as a high-speed interceptor for engaging jet targets. However, publicly available data does not currently indicate a true speed advantage over the STRILA.
Foreign analogues
On a global scale, the niche of “cheap effectors” is being developed by:
- Raytheon Coyote Block 2/3 – kinetic and non-kinetic interception, integrated with the KuRFS radar, as part of the LIDS system; the cost of one effector is estimated at $100–300;
- The Anduril Roadrunner is a twin-engine VTOL aircraft with AI control via the Lattice platform and multiple return to base capability in the absence of a target.
Compared to the Coyote and Roadrunner, the Ukrainian Jet appears to be a significantly simpler and potentially significantly cheaper solution—even taking into account the inevitable cost increase due to the turbojet engine and ejection launch device.
Interception Economy
The main argument in favor of the entire class of interceptor UAVs is economics. According to Defense News and Breaking Defense:
- “Shahed”/“Geranium-2” is estimated at $10–15 thousand, “Geranium-3” – $20–30 thousand;
- Ukrainian light interceptors - $1–5 per unit;
- Rocket Patriot air defense missile system – over $3 million per launch.
Interceptor/target cost ratio when used drones The ratio drops to 1:5–1:10 in favor of the defense, while with the Patriot it reached 85:1, unfavorable for the defenders. Even if the Chaklun Jet with a jet engine and catapult costs $8–20, it will remain significantly cheaper than both heavy air defense systems and the Geran-3-class targets it engages.
Production figures: what requires caution
Ukrainian sources cite impressive figures: 100 interceptors produced by 2025; up to 1500 delivered to troops per day; and 33000 downed Russian UAVs in March 2026. The last figure should be taken with caution: with the stated 6300 combat sorties per month, a ratio of 33/6300 ≈ 5 targets per sortie is physically unrealistic. More conservative estimates from Breaking Defense suggest that one in three UAVs downed over Ukraine is destroyed by an interceptor, and over Kyiv, the proportion of Shahed intercepts by drones in February 2026 exceeded 70%. These figures appear more plausible.
Open questions about Chaklun Jet
By systematizing the gaps in information, we can highlight:
Confirmed (from exhibition materials): type, presence of turbojet engine, flight performance characteristics, ejection launch, purpose.
Unconfirmed: specific engine model; warhead type and weight; cost; developer; project stage; integration with CD-T10 radar (X-band, 15 km); autonomous acquisition algorithms; ChaklunLRS channel interference immunity; test results on high-speed targets similar to the Geran-3.
International context
Ukrainian interceptors have already attracted international interest. Sting and Octopus are mentioned in connection with orders from Persian Gulf countries; for Octopus, there is an agreement with the UK for a production rate of 1000 units per month. NATO, through the Eastern Sentry initiative, is strengthening air control of the eastern flank, and the LEAP program aims to develop "low-cost effectors" by 2027. The promotion of the Chaklun Jet at SAHA 2026 fits into this overall context: demand for compact and fast interceptors is growing beyond the Ukrainian theater.
Conclusions
The Chaklun Jet is a logical, yet still largely "paper" response to the evolution of attack UAVs toward jet speeds. The aircraft has compact dimensions, a theoretically sufficient ceiling for its class, and a fundamentally different type of propulsion system for light interceptors. If its stated characteristics are confirmed by real-world tests, it could carve out its own niche in Ukraine's multi-tiered interceptor system. Defense.
However, this is not a "wunderwaffe," and there is no reason to talk about combat readiness yet. The claimed speed of 320 km/h is not impressive, even compared to Ukrainian electric interceptors; the turbojet engine and catapult increase the system's cost; the operational range is limited by the radio link; autonomous capabilities have not been proven in practice; the manufacturer has not been officially named; and the project's status is unclear.
More broadly, the idea itself—a mass-produced, relatively inexpensive turbojet interceptor against high-speed attack UAVs—reflects the mainstream development of short-range air defense. Developers in the US (Coyote, Roadrunner), the UK (LEAP program), Turkey, and several other countries are pursuing this path. The competitiveness of the Ukrainian prototype will be determined by test results and the reaction of foreign customers. For now, it's appropriate to refer to the Chaklun Jet as a promising concept, not a ready-made weapon system.
