Izdeliye 305, commonly called LMUR, is a Russian helicopter-launched air-to-surface guided missile developed by KB Mashinostroyeniya for long-range precision attacks from Mi-8, Mi-28, and Ka-52 family helicopters. The missile combines inertial/satellite navigation with an electro-optical seeker and operator-in-the-loop terminal control, giving Russian crews a standoff weapon documented in Ukraine against vehicles, bridges, buildings, and other point targets.
Russian forces have used LMUR/Izdeliye 305 missiles in Ukraine from helicopter platforms; Oryx tracked visually confirmed strikes, TWZ documented Mi-28NM footage showing LMUR carriage and launch, and UK defence reporting described Ka-52M crews exploiting the missile's roughly 15 km reach in southern Ukraine.
Role detailsLMUR is heavier and longer-ranged than many older Russian helicopter-launched anti-tank missiles, and its guidance chain changes how the launching helicopter can break away after firing.
| Feature | Documented detail | Source context |
|---|---|---|
| Midcourse navigation | Inertial and satellite navigation move the missile toward the target area before terminal seeker use. | Rosoboronexport and TWZ |
| Terminal seeker | Open sources describe an electro-optical or thermal-imaging seeker that can send imagery to the crew through a datalink. | Rosoboronexport and TWZ |
| Operator control | The crew can select, switch, or cancel a target during flight when the helicopter carries the required communications equipment. | TWZ |
| Launch evidence in Ukraine | TWZ reported January 2023 footage showing Mi-28NM helicopters carrying LMUR missiles on APU-L rails and launching one during a mission. | TWZ |
| Ukraine target set | Oryx tracked visually confirmed Ukraine strikes against vehicles, pontoon bridges, buildings, warehouses, outposts, a tent, and a smokestack. | Oryx |
Public sources use several closely related designations for the combat, export, and training branches of the LMUR family.
| Variant | Configuration | Designation notes |
|---|---|---|
| Izdeliye 79 | Prifiks R&D precursor | TWZ traces the 2011 Prifiks development order to an Izdeliye 79 lightweight multirole guided missile effort before the later Izdeliye 305 program. Sources: TWZ LMUR Ukraine analysis |
| Izdeliye 305-UL | Flying training missile | TWZ describes the 305-UL as a practice missile without the combat warhead and with a smaller non-folding wing. Sources: TWZ LMUR Ukraine analysis |
| Izdeliye 306 | Probable alternate-warhead variant | TWZ says documents for the Mi-8MNP-2 mention Izdeliye 306 alongside Izdeliye 305 and treats it as an unconfirmed likely LMUR variant with a different warhead. Sources: TWZ LMUR Ukraine analysis |
Open sources identify the missile as a helicopter-launched weapon, with Rosoboronexport naming export carrier families and TWZ describing Russian integration work.
| Launcher | Launcher type | Launch evidence |

 | Attack helicopter | Rosoboronexport lists Mi-28-family helicopters among 305E carriers; TWZ reports Mi-28NM tests with LMUR beginning in 2019 and Ukraine footage in January 2023 showing Mi-28NM helicopters carrying and launching the missile.

The same missile family appears under multiple names in English-language reporting and Russian export material.
| Name | Use in sources | Catalog interpretation |
|---|---|---|
| LMUR | Russian acronym for light multipurpose guided missile. | Common English shorthand for the family. |
| Izdeliye 79 | TWZ links the 2011 Prifiks work to an earlier lightweight multirole missile effort. | Development precursor, not the main combat identity. |
| Izdeliye 305 | Russian service designation discussed in development and Ukraine-use reporting. | Main combat missile identity for this record. |
| 305E | Rosoboronexport product designation for the export missile. | Export configuration and official specification source. |
| Izdeliye 305-UL | TWZ describes a practice missile without the combat warhead. | Training branch, not a separate conflict-use record. |
| Izdeliye 306 | TWZ reports the designation in Mi-8MNP-2 documentation and treats the warhead explanation as unconfirmed. | Probable alternate-warhead branch, kept caveated. |
