Saudi Arabia is upgrading its al-Duwadimi missile complex to manufacture solid-fuel missiles, with operations expected to begin by the end of 2026. This development marks a shift toward domestic long-range strike capabilities aimed at regional deterrence. The project also introduces new complexity to ongoing US-Saudi diplomatic talks regarding nuclear cooperation and international security standards.
Saudi Arabia is increasing its production capabilities at the al-Duwadimi missile complex, located approximately 125 miles west of Riyadh. New satellite data captured between April 2025 and September 2026 shows that the kingdom is constructing advanced infrastructure, including casting pits and blast-diverting walls, which are specialized setups for manufacturing solid-fuel missile motors.
Solid-fuel missiles are distinct from liquid-fueled versions because they can be stored for long periods and launched rapidly, making them a more practical choice for modern defense arsenals. Analysts tracking the site suggest the new facilities are designed to support the production of heavier, longer-range systems, a move that potentially utilizes designs modeled after Chinese technology. This facility is expected to become operational for missile production by the end of 2026.
The strategic goal behind this expansion is to strengthen domestic military capabilities. By building the capacity to produce long-range missiles, Riyadh aims to improve its regional deterrence against potential threats, specifically regarding missile and drone activity. This move is part of a broader strategy to reduce the kingdom's dependence on Western-supplied tactical fighter aircraft for deep-strike defense missions.
However, this industrial expansion carries geopolitical implications. The development of indigenous long-range strike technology may face scrutiny from international non-proliferation watchdogs. Additionally, the timing of the project’s growth coincides with delicate US-Saudi diplomatic discussions regarding a civilian nuclear cooperation agreement. Critics in the US government may use the expansion as a point of contention, citing concerns over the lack of stringent safeguards regarding enrichment technology, despite Riyadh’s assertions that its nuclear programs are exclusively for energy generation.
For regional security observers, the key monitorable will be the transition of the al-Duwadimi site to full operational status by year-end. The development highlights a wider trend across the Middle East, where nations are increasingly focusing on fortifying their own military-industrial bases to handle regional security challenges independently, rather than relying solely on external procurement.
