N12 analyst Asaf Rosenzweig reported on Wednesday that Russia is providing Iran with the Regiment propulsion system, a technology described as critical for closing a gap in Iran's missile array. According to Rosenzweig, the system is considered particularly advanced, though he noted there is no indication that Iran has fielded a missile using it at an operational level. He added that Russian direct assistance to the program continued in 2026, including during the height of the war with Iran, with the latest documents reviewed dating from June. The report follows a series of prior disclosures about Russian-Iranian military cooperation. As The Zioneer has previously reported, Russia has provided Iran with upgraded drone technology, satellite intelligence, and navigation systems for precision strikes, alongside broader diplomatic and material support amid Moscow's deepening alliance with Tehran. The new disclosures highlight the ongoing transfer of advanced propulsion technology — a domain that directly affects the range, speed, and survivability of Iranian ballistic missiles.
