The 1L271 Aistyonok is a Russian portable mortar-locating and artillery-reconnaissance radar associated with NPO Strela inside the Almaz-Antey industrial group. Rosoboronexport describes the export system as a modular radar for battalion-to-brigade fire support: detecting 81-120 mm mortar positions, tracking shell bursts for artillery correction, and observing moving ground targets out to 20 km. Specialist radar references describe a 135 kg J-band set, while open-source conflict reporting documents Russian-linked use in Syria and Ukraine plus Armenian/Artsakh wartime fielding problems in the 2020 Nagorno-Karabakh conflict.
Russian and Russian-backed forces are documented with 1L271 Aistyonok/Aistenok radars in Ukraine, including 2016 Donbas OSINT reporting, a Ukrainian capture near Rubtsi in 2022, Russian MoD-attributed Kupiansk-axis counter-battery reporting, and later visually documented destroyed or captured Russian examples.
Role detailsRussian state reporting attributed to the Russian MoD placed Aistenok systems around Aleppo for ceasefire monitoring and artillery reconnaissance, and separate RIA reporting said a Syrian government army representative thanked Russia for providing an Aistenok system.
Role detailsArmenian prosecution-linked reporting says Aistenok systems delivered to Armenian and Artsakh units before the war were found unsuitable during the 2020 Nagorno-Karabakh fighting and removed from use; prewar Nagorno-Karabakh exercise sightings support operator context but not combat performance.
Open-source reporting ties Aistyonok use to three different operational settings: Russian or Russian-backed counter-battery work in Ukraine, Russian and Syrian government ceasefire-monitoring and artillery-reconnaissance activity around Aleppo, and Armenian/Artsakh wartime fielding problems during the 2020 Nagorno-Karabakh fighting.
Captured, destroyed, and drone-struck Russian examples show the radar as a battlefield sensor for locating Ukrainian artillery and mortar positions.
Russian and Syrian government reporting placed Aistenok systems in ceasefire-monitoring and artillery-reconnaissance roles around Aleppo.
Armenian prosecution-linked reporting says delivered Aistenok systems were removed during the 44-day war after being judged unsuitable for use.
Rosoboronexport frames Aistenok as a ground-reconnaissance radar for mortar and artillery units rather than as a stand-alone weapon. Its published tasks center on detecting mortar launch positions from bomb trajectories, monitoring shell bursts for artillery correction, and tracking moving ground targets such as tanks.
Detects 81-120 mm mortar positions and monitors mortar fire to support counter-battery response.
Registers shell-burst data for 122-155 mm artillery fire monitoring and adjustment.
Detects moving ground targets, with the export sheet listing tank-size target detection out to 20 km.
The portable configuration is documented as a set of separate field components. Rosoboronexport lists a transceiver, antenna, preprocessing unit, control panel, power supply, data-transfer equipment, radio, generator, tripod, and artillery boussole; Radartutorial describes a 135 kg set operating in the J band with eight selectable frequencies.
Antenna, transceiver, control, power, communications, tripod, generator, and orientation equipment are carried as a deployable radar set.
Specialist radar data identifies J-band operation with multiple selectable frequencies.
At 135 kg in the autonomous version, the radar is portable in modules but still crew-served field equipment.
Aistyonok sits in a broader Russian and Soviet artillery-reconnaissance radar line rather than a same-family variant set. Existing catalog neighbors show the spread from tracked Soviet counter-battery radars to newer Russian NPO Strela systems.
| Related system | Relationship | Source-backed context |
|---|---|---|
 | Earlier tracked radar | TopWar places Rys, Zoopark, Aistyonok, and Yastreb-AV in the domestic counter-battery radar development line, with Rys originating at Tula NII Strela. |
 | Newer self-propelled radar | Russian state and military press reporting identify NPO Strela production context for Yastreb-AV, Zoopark-1M, and Aistenok artillery-reconnaissance radars used for counter-battery work. |
 | Portable ground-reconnaissance radar | Both records trace to Tula NPO Strela portable radar work; Sobolyatnik covers a lighter ground-surveillance role, while Aistyonok is framed around mortar locating and artillery fire control. |
