The 5P85SM is a modernized self-propelled S-300PM-family launcher developed after the 5P85S/D master-slave arrangement. It carries four 48N6-family missile canisters on a MAZ-543M-family chassis, uses improved prelaunch and autonomous power equipment, and appears in Russian S-300PM-family visual-loss reporting from Ukraine.
Russian S-300 PMU(-1) 5P85SD/SM launchers are listed among visually documented full-scale-invasion losses; a contemporaneous report also relayed a claimed Russian 5P85SM S-300PM1/PM2 launcher loss in Zaporizhzhia Oblast, though later reporting treated the Ilyine incident as a 5P85SM2-01 S-400 launcher.
Role detailsThe 5P85SM sits between the earlier S-300PS 5P85S/D launchers and later export or S-400 launcher lines. Sources use 5P85SM for the S-300PM self-propelled launcher, 5P85SE for closely related S-300PMU-series export launchers, and 5P85SE2 or 5P85SM2-01 for later adjacent configurations rather than exact proof of every 5P85SM loss claim.
| Variant | Configuration | Designation notes |
|---|---|---|
 | Earlier S-300PS master launcher | The earlier 5P85S used the S-300PS master-launcher role and controlled dependent 5P85D launchers; the 5P85SM abolished that 5P85SD launcher-complex arrangement in favor of launchers directly integrated with the S-300PM system. |
 | Earlier S-300PS dependent launcher | The dependent 5P85D belonged to the older S-300PS launcher group; 5P85SM modernization removed the need for a local 5P85S master controlling two 5P85D launchers. Sources: Missilery S-300PMU-1 |
| 5P85SE / 5P85SE2 | Export and later-family self-propelled launcher line | Open references describe 5P85SE as an autonomous S-300PMU/PMU-2 launcher and list 5P85SM/SE configurations across S-300PM, S-300PMU-1, and S-300PMU-2 family tables.

The 5P85SM is useful as a launcher entry because its role depends on the S-300PM-series battery architecture and associated engagement radar rather than independent targeting.

 | Long-range surface-to-air missile family | Missilery describes the S-300PM / S-300PMU-1 system as a further development of S-300PS using the 48N6 missile generation, with up to twelve self-propelled or towed launchers tied to radar and command vehicles. Sources: Missilery S-300PMU-1 |
| Earlier S-300PS master launcher | The 5P85SM retained the four-canister self-propelled launcher concept but replaced the older 5P85S-centered launcher-complex dependency with direct interaction with the S-300PM engagement-radar control cabin. |
 | S-300PM-family engagement radar | S-300PMU-1 and Favorit/S-300PMU-2 references place 30N6E1 or 30N6E2 illumination-and-guidance radars in the same fire-unit architecture as 5P85SE or 5P85TE launchers, underscoring that the TEL depends on battery radar and command assets for target engagement.

The 5P85SM was developed for the S-300PM generation as an upgraded self-propelled launcher. Sources describe it as retaining four containerized missiles on a MAZ heavy wheeled chassis while adding improved prelaunch preparation equipment, drive-control hardware, autonomous power, hydraulic improvements, and remote launch sequencing from the engagement-radar control cabin.

The older 5P85S-plus-5P85D launcher group was replaced by launchers interacting directly with the S-300PM radar-control cabin.
The launcher includes an improved built-in autonomous power source and supports remotely commanded verticalization, prelaunch preparation, and firing.

Oryx lists Russian S-300 PMU(-1) 5P85SD/SM launchers among visually documented losses, while a contemporaneous Zaporizhzhia report identifying a 5P85SM was later complicated by S-400 5P85SM2-01 reporting for the Ilyine incident.
