> russia is expanding its solid-propellant motor-production facilities > russia is engaged in what us officials describe as the most ambitious expansion in military manufacturing since the soviet era. satellite imagery suggests that solid-propellant rocket motor-production capacity appears to be one focus of this effort. > substantial development activity is visible at five sites associated with the production of solid propellants. recent satellite imagery suggests building work is taking place at multiple locations, including possible refurbishment of dormant soviet-era facilities and the construction of new infrastructure. this work is noteworthy given that for the last 30 years there has been little evidence of expansion or refurbishment. only in 2023, three decades after the collapse of the soviet union, did substantial investment appear to be underway.
