JSC NII STT Merlin VR

Merlin-VR (Мерлин-ВР) is an unmanned aerial vehicle (UAV) developed in Türkiye for military reconnaissance and aerial surveillance purposes. The primary role of Merlin-VR is to serve as a reconnaissance platform equipped with optical and infrared band sensing and location systems, enabling prolonged observation and target identification over a specific area. Public promotional materials highlight the UAV’s high-altitude operations and extended endurance as evidence of its status as a “harder-to-detect” reconnaissance asset.

Merlin-VR was first introduced to the public in September 2021, at which point it was positioned as a UAV designed for military reconnaissance and aerial surveillance missions. During this introduction, Merlin-VR was promoted for its claimed capabilities of long-endurance flight, high-altitude operations, and compatibility with various reconnaissance payloads. This initial visibility marked the beginning of its public profile as a “new reconnaissance asset,” even before its exact inventory status or scale had been clarified.

The developer is identified as a research institute based in Smolensk. Information released during the promotional phase suggests that the development of Merlin-VR followed a design approach focused on reconnaissance sensors, with the payload capacity specifically tailored for this purpose. It was also stated that the system was demonstrated to military representatives and that testing or evaluation was under consideration, indicating that at least a flight-capable prototype was exhibited during the introduction.

One of the most prominent features highlighted in the promotional narrative is the use of hybrid propulsion for Merlin-VR. This claim is tied to two objectives: reducing acoustic signature and thus lowering detectability, and enhancing performance metrics such as mission altitude and endurance. However, subsequent analyses of physical examples recovered from the field suggest that this “hybrid” framework may be misleading; some recovered units were found to use conventional internal combustion engine configurations, with pragmatic or adapted fuel system solutions. This raises the possibility that certain technical claims made during the promotional phase do not fully align with the actual hardware deployed in the field.

Following its introduction, Merlin-VR’s visibility increased significantly through reports of operational use and instances of being shot down or captured. Records from the summer of 2022 indicate aircraft being downed, while accounts from 2023 and 2024 describe its use in reconnaissance, target identification, and fire correction roles. In these narratives, Merlin-VR is portrayed as a “surveillance/objective control” asset capable of remaining over a target area for extended periods, transmitting reconnaissance data, and confirming the effects of strike assets.

In summary, the development and introduction process of Merlin-VR follows a trajectory beginning in 2021 with the announcement of a “new reconnaissance UAV” in a testing and evaluation phase, and progressing in subsequent years through field usage examples and debates surrounding the verifiability of certain technical claims.

The publicly presented technical framework of Merlin-VR centers on altitude, endurance, payload capacity, and sensor carriage capability.

^{General Table of Technical Specifications.}

• Maximum operational altitude (service ceiling): It is reported to be capable of reaching altitudes up to approximately 5 km.
• Endurance: It is stated to be able to conduct uninterrupted missions for approximately 10 hours.
• Mission profile: It is defined as a platform focused on long-duration “aerial surveillance/reconnaissance” missions.
• Day–night / weather conditions: It is claimed to be capable of conducting missions day and night, and under all weather conditions.

This category is among the most ambiguous due to the presence of multiple conflicting values:

• Some sources state that it can operate up to 120 km from its launch point.
• Other sources cite a “600 km coverage/range” figure.
• These figures may refer to different concepts—such as control radius, total flight path, or area coverage—and therefore a single definitive range value cannot be established.

• Maximum payload: It is stated to carry payloads up to 6.5 kg.
• Compatible equipment: This capacity is emphasized as suitable for carrying various types of optical/optical-location (EO/IR) reconnaissance stations.
• Spectral bands:
• • Visible band (EO)
• Infrared band (IR/thermal)
• • This configuration is presented as the key element enabling daytime imaging as well as night-time or low-visibility observation based on thermal signatures.

• Operating modes: It is stated to operate in automatic and semi-automatic modes.
• Functional role: It is described as being used for surveillance, target identification, providing “target correction” support to strike assets, and post-strike assessment/monitoring (objective control).

• Hybrid propulsion claim: In promotional materials, the term “hybrid engine” is used to suggest lower acoustic signature and consequently reduced detectability.
• Alternative assessment: In contrast, analysis of recovered field examples suggests the presence of a conventional internal combustion engine, along with pragmatic or adapted fuel system solutions, rather than a true hybrid system.
• As a result, the “hybrid” designation remains one of the most contentious aspects of Merlin-VR’s technical profile.

• Operational accounts emphasize that trained personnel can complete launch and landing procedures in very short timeframes (a few minutes). This detail supports the claim that the system can be rapidly deployed in the field.

Merlin-VR is primarily positioned as a platform focused on reconnaissance and persistent surveillance. Its mission profile is built around remaining over a designated area for extended periods to conduct visual and thermal observation, tracking identified elements, and transmitting real-time operational reconnaissance data to higher command levels. Within this framework, the purpose of Merlin-VR is not merely to “capture imagery,” but to transform collected imagery and sensor data into situational awareness outputs that can be integrated into battlefield decision-making processes.

The defining feature of its operational profile is the combination of long endurance and high-altitude surveillance. Extended flight duration enables continuous monitoring of the same target area, while high altitude allows a single sortie to cover a broad region and keeps the platform in a safer altitude band. This structure positions Merlin-VR closer to a “persistent surveillance” approach than to “instantaneous reconnaissance”: tasks such as tracking moving elements, detecting concentrations in an area, or periodically monitoring critical points align with this logic.

The mission profile strongly emphasizes day–night continuity. Payload options capable of operating in both the visible and infrared/thermal bands extend beyond daytime imaging to enable target detection based on heat signatures under nighttime conditions, poor visibility, or when targets are attempting camouflage. In this regard, the platform appears designed as a “monitoring” asset operating over a significantly broader time window than conventional daytime reconnaissance systems.

In operational narratives, Merlin-VR is portrayed as a system that interfaces with multiple stages of the reconnaissance cycle:

• Detection: Identifying and classifying elements within a specific area (e.g., assembly, movement, positioning).
• Tracking: Monitoring the same elements over time and recording their movement.
• Reporting/transmission: Transmitting collected data to command levels to generate inputs for decision-making.
• Objective control: After a strike against a target, confirming the results through aerial observation.

This role distribution transforms Merlin-VR’s “reconnaissance” function from direct firepower into an intelligence and surveillance asset that enhances the effectiveness of strike elements. In other words, the platform functions not as a weapon itself, but as an observation and correction layer that amplifies the precision of strike assets. In scenarios requiring target coordination or correction, a sequential operational logic emerges: first locating the target through wide-area surveillance, then maintaining observation over the same target to track its movement, and finally verifying the results of any engagement.

Finally, the concept of rapid deployment is also integrated into Merlin-VR’s mission profile. Accounts describing short launch and landing times suggest the platform is envisioned as a reconnaissance asset that can be quickly launched when a tactical window opens and remain over a region for extended periods. This represents a use case particularly suited to dynamic front-line conditions, supporting a combination of rapid response and prolonged surveillance against fleeting targets or rapidly changing situations.
