The 1L271 Aistyonok is a Russian portable mortar-locating and artillery-reconnaissance radar built for battalion-to-brigade fire support. Rosoboronexport describes the export system as a modular radar for 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 radars in Ukraine, from InformNapalm's 2016 Donbas reporting to later Russian MoD-linked Kupiansk-axis counter-battery accounts; Ukrainian and open-source reporting also documents captured, destroyed, and drone-struck Russian Aistyonok systems.
Role detailsRussian MoD-attributed and Syrian government reporting described Aistenok systems being used around Aleppo for ceasefire monitoring and artillery reconnaissance, including Russian monitoring from the Al-Khalidiyah area and Syrian government acknowledgement of a provided Aistenok system.
Armenian prosecution-linked reporting says 15 Aistenok systems bought through Rosoboronexport were delivered to Armenian and Artsakh units before the war, but during the 2020 Nagorno-Karabakh fighting they were judged unsuitable for use and removed from service.
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 built around separate field components rather than a vehicle-mounted radar cabin. 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.
Radartutorial describes 1L271 as having been presented at military fairs since 2008, aligning the radar's public appearance with late-2000s export and service promotion.
