Overview
- Ukraine’s military intelligence posted an interactive 3D model and full component list of the S-71K on Monday on its War&Sanctions portal.
- The agency attributes the missile’s development to United Aircraft Corporation for the Su-57 stealth jet and says it first saw combat late last year.
- The dossier says the weapon uses an R500 turbojet by Reynolds LLC and carries a 250 kg OFAB-250-270 high‑explosive bomb as its warhead, with a composite body and an estimated 300 km range.
- DIU says most of the missile’s electronics come from the United States, China, Switzerland, Japan, Germany, Taiwan, and Ireland, revealing how foreign parts still feed Russia’s arms production.
- GUR calls for stronger sanctions and notes Russia is considering future use from the S-70 Okhotnik drone, a potential pairing with stealth platforms that would cut Ukraine’s time to detect and intercept.
