- Satellite imagery published by Dnipro OSINT indicates that an overnight Ukrainian strike on the Promsintez explosives plant in Chapayevsk did not directly hit the main production workshops
- Of the three FP-5 cruise missiles reportedly launched, one was intercepted and two detonated adjacent to the facility, causing only limited peripheral damage according to open-source assessments
New satellite imagery published by Dnipro OSINT indicates that an overnight Ukrainian strike on a Russian explosives production facility in Chapayevsk on March 28 failed to directly hit the main production workshops.
The target was identified as the JSC Promsintez plant, a site involved in the manufacture of explosive materials used in ammunition and aerial weapons, making it a key component of Russia’s military-industrial supply chain.
According to Dnipro OSINT, three cruise missiles were launched during the strike. One was reportedly intercepted by Russian air defenses, while the remaining two impacted near the production halls rather than penetrating the buildings themselves.
Satellite imagery and open-source assessments suggest the first missile detonated before reaching the intended workshop after striking a pole during the final approach. The facility it appeared to be targeting had reportedly been attacked previously by Ukrainian drones. The second missile also impacted close to the production building and may have caused minor peripheral damage, but the available imagery does not indicate a direct strike on the main workshop.
Analysts from the Exilenova+ OSINT community said the missiles appeared to be on course and that the issue was not one of guidance accuracy. According to their assessment, “The missiles were flying directly at the target. The issue here is not accuracy. The first one was shot down literally at the last moment, right before the workshop. The second hit the lightning rod tower. It was simply bad luck.”
That assessment is consistent with the imagery, which places the impact points immediately adjacent to the intended structures. From an operational standpoint, this suggests that the strike package achieved accurate terminal approach but failed to deliver direct structural penetration of the production halls.
The missile used in the strike was identified as the FP-5, a Ukrainian-developed cruise missile platform associated with long-range precision strike missions. While detailed technical specifications remain limited in open sources, systems in this category are typically designed for low-altitude terrain-following flight profiles intended to reduce exposure to radar and air defense systems during ingress.
The reported outcome of this strike highlights the challenges of attacking defended industrial targets, particularly where point air defense systems remain active near the objective. Even when missile guidance appears accurate, interception or last-second deflection can prevent direct impact on critical infrastructure.
That said, near-miss detonations can still generate blast and fragmentation effects, potentially causing localized damage to surrounding structures, utility lines, or access routes. Based on the currently available imagery, however, there is no clear evidence that the main explosives production workshops sustained direct destructive hits.
