28th Guards Missile Division
Identification
The coordinates and hierarchy fit the Kozelsk-based 28th Guards Missile Division of the Strategic Rocket Forces. Open-source RVSN reference material traces military unit 54055 in Kozelsk to the formation that became the 28th Guards Missile Division, and a 2024 Kozelsk court ruling shows unit 54055 remains associated with an active military area in the city.

Missile posture
By 17 December 2025, Russian reporting said the last silo-loaded RS-24 Yars for the Kozelsk formation had been placed into a silo, completing the division’s silo-based Yars rearmament. A January 2026 status review by Pavel Podvig assessed the division at 30 silo-based Yars missiles. ([interfax.ru](https://www.interfax.ru/amp/1063622))
Regimental layout
Specialist strategic-force reporting on the completed Kozelsk deployment identifies three active Yars regiments—74th, 168th, and 373rd. The same source says the older 119th, 214th, and 372nd regiments were disbanded around 2007–2009, so some legacy open-source labels for Kozelsk regiments may be outdated.

Support infrastructure
The Kozelsk complex includes a built-up garrison area as well as missile infrastructure. In 2024, the Kozelsk district court described land tied to unit 54055 as containing an active military unit with military infrastructure and residential buildings. Open-source RVSN reference material also associates the division with the 292nd communications node and the 2506th technical missile base, the latter listed at Kozelsk-5.

Operational significance
Kozelsk has been the Strategic Rocket Forces’ lead silo-based Yars conversion site: Russian military reporting said it was the first formation rearmed with silo-based Yars, and satellite-based analysis documented conversion of former SS-19/UR-100NUTTH silos to the new system while the active field contracted to three regiments. For this location, the key observable is hardened fixed-launch infrastructure rather than road-mobile dispersal. ([tass.com](https://tass.com/defense/1550895))
