The DRL-27SE is the dispatch and terminal-area air-traffic-control radar module used in Russia's RSP-28ME mobile and RSP-27SE stationary radar landing-system families. In the 2014 Russia-Ukraine War, open-source loss records and Ukrainian defense reporting identify a DRL-27SE module in an RSP-28ME complex at occupied Belbek air base as damaged or destroyed during a Ukrainian drone strike in May 2026.
Russian forces had a DRL-27SE module in an RSP-28ME landing-radar complex at Belbek air base in occupied Crimea; WarSpotting records the module damaged on 2026-05-17, while Oryx lists it as destroyed and Ukrainian defense reporting describes drone damage to the same module.
Role detailsThe DRL-27SE is documented as a module within the RSP-28ME mobile radar landing system rather than as a standalone strike or air-defense weapon. Russian product descriptions list it alongside PRL-27SE or PRL-27SM landing-radar modules, an automatic radio direction finder, the RSP-28ME control module, and a diesel power station.
Airfield dispatch and near-zone air-traffic-control radar for the RSP-28ME complex.
Technical analysis describes RSP-28ME and RSP-27SE as sharing DRL and PRL module architecture, with the mobile RSP-28ME adding a control/workstation module for operational airfields.
Open-source records place the DRL-27SE module at Belbek air base after a Ukrainian drone strike in May 2026, with damaged and destroyed status differing by tracker.
Source coverage ties the DRL-27SE to LEMZ/Lianozovo Electromechanical Plant, a PJSC ALMAZ R&P Corp. division within the wider Almaz-Antey industrial group. The RSP-27SE product description says the DRL-27SE provides circular near-aerodrome surveillance through a primary radar channel and secondary RBS and ES GRLO channels, while the Kharkiv Air Force University analysis describes the Russian RSP-27SE/RSP-28ME family as using phased-array DRL and PRL modules.
Near-aerodrome detection and range/azimuth measurement for aircraft around the airfield.
RBS and ES GRLO channels for aircraft carrying compatible transponders, including RBS A/C and ES GRLO IV/VI modes in the RSP-27SE description.
The catalog keeps Almaz-Antey as the validated manufacturer facet, while source notes identify LEMZ as the specific plant/division associated with the radar landing-system family.
Defense reporting on the Belbek strike describes the RSP-28ME as supplied to Russian armed forces from 2021, matching the system context for the DRL-27SE module.
