February 11 Plant

February 11 Plant is a secretive North Korean defense plant in the Hamhung area that open reporting links to the Ryongsong Machine Complex and to the production and expansion of the Hwasong-11 family of solid-fuel ballistic missiles. Its public relevance comes from satellite-imagery analysis, North Korean state-media factory imagery, and reporting on the KN-23 and KN-24 family names applied outside North Korea.

February 11 Plant is a heavily concealed North Korean weapons factory in the Hamhung area that analysts identify through satellite imagery and official photo comparisons. Open reporting places it inside the Ryongsong Machine Complex and treats it as a key missile-production node in North Korea's east-coast industrial belt.

The plant is associated in open sources with the KN-23 / KN-24 missile family and broader Hwasong-11 solid-fuel tactical ballistic-missile production. Because the facility operates behind a limited public information wall, public description should stay close to what analysts, official reports, and state media have directly described.

Public references use several spellings and levels of specificity for this secretive North Korean plant. Open sources identify the site through imagery, analysis, and state reporting rather than through a public corporate web presence. No rights-clear reusable manufacturer image was verified during this task, so images are omitted.

The KN-23 is a road-mobile, quasi-ballistic SRBM with an estimated maximum range of about 690 km, while the KN-24 is a smaller ATACMS-like tactical ballistic missile assessed at roughly 410 km. Recovered debris, official U.S. and Ukrainian analysis, UN-panel inspection work, and independent component tracing tie transferred DPRK missiles to Russian strikes in the 2014 Russia-Ukraine War.

Open sources place it in the road-mobile, solid-fuel branch derived from the Hwasong-11A / KN-23, with North Korean reporting claiming a heavy 2.5-ton payload in 2021 and a later 4.5-ton-class warhead test series in 2024. Later analysis describes the Hwasong-11E hypersonic-glide-vehicle branch as using the larger Hwasong-11C booster and launcher base, but no source-backed direct combat use for this exact Hwasong-11C variant was found.
