The 5N84A Oborona-14 is a Soviet/Russian VHF early-warning radar in the P-14 Tall King family, built around a very large folding antenna for long-range detection of airborne targets. Open technical references describe it as a two-coordinate station that measures range and azimuth for air-defense command systems or autonomous users, while 2026 reporting documented a Russian Oborona-14 radar destroyed by Ukrainian Special Operations Forces in occupied Crimea.

Role in Conflicts

Crimea Strike Context

March 2026 reporting placed the Russian Oborona-14 at Yevpatoriia inside the wider radar layer protecting occupied Crimea. Ukrainian SOF-sourced reports grouped it with a Nebo-U radar and two radars inside a radio-transparent dome, while WarSpotting lists the same Oborona-14 item as a Russian radar loss at Yevpatoriia.

Reported operator

Russia, in occupied Crimea during the Russia-Ukraine war.

Reported site

Yevpatoriia, Crimea, in Ukrainian SOF-sourced and WarSpotting reporting.

Reported function

Long-range air surveillance and early warning for Russian air-defense coverage.

Modernization caveat

Ukrainska Pravda attributes the 5N84AE2/AM modernization assessment to CyberBoroshno OSINT analysts.

Radar Role And Configuration

Oborona-14 is a sensor in the air-defense network rather than a missile launcher. RusArmy describes it as a long-range radar for detecting airborne targets and measuring range and azimuth when operating autonomously or with automated command systems.

Radar band

Meter-band / VHF surveillance radar.

Coordinate type

Two-coordinate radar: range and azimuth, with height information supplied by separate height-finding equipment when needed.

Deployment package

Six transport units: two equipment semitrailers, two antenna-mast units, and two power-supply trailers in the RusArmy description.

Remote post

A separate semitrailer control post with two indicators can be placed up to 1 km from the radar.

Scan modes

Lower-beam, upper-beam, and alternating scan modes trade low/mid-altitude range against upper-elevation coverage.

Variants

Oborona-14 sits in the P-14 / Tall King VHF radar family. Open sources distinguish the earlier 1RL113 Lena, the 44Zh6 Furgon stationary version, the 5N84A Oborona-14 transportable form, and later modernization packages that retain the basic P-14/5N84A lineage while replacing much of the electronics.

P-14MLModernized P-14/5N84A package

Altimus-Tech describes P-14ML as an upgrade for legacy P-14, 44Zh6, and 5N84A Oborona-14 radars, preserving the VHF band while adding solid-state electronics, digital processing, electronic frequency agility, and automatic tracking.

Ukrainska Pravda reported CyberBoroshno's assessment that the Yevpatoriia radar struck in March 2026 was a modernized 5N84AE2/AM-type system visually related to the older 5N84A Oborona-14.

It is a two-coordinate predecessor to the 1L119 Nebo-SVU: sources describe it with a 72-element VHF antenna array, separate IFF interrogator, six-person crew, and fighter-target detection figures reaching roughly 350 km at high altitude.

Public reporting describes the system as a multi-vehicle package with a radar/antenna vehicle, command or operator-control vehicle, and power-support vehicle on KamAZ chassis, while Rosoboronexport markets the export Podlet-K1KE for automated detection, tracking, identification, and flight-information tasks in air-defense and air-force radio-engineering units. Ukraine-war reporting documents Russian Podlet-K1 losses and strikes tied to the S-300 and S-400 air-defense network.

It provides search, target tracking, fire-control, and missile-guidance support for Vityaz batteries, while official export data for the S-350E family gives the multifunction radar 150 km circular-scan and 230 km fixed-sector air-target detection modes. WarSpotting documented a Russian 50N6A radar destroyed in Donetsk oblast on January 1, 2026, making the component directly visible in the 2014 Russia-Ukraine War rather than only through its parent S-350 system.
