Lockheed Martin and Rheinmetall have officially moved forward with a co-production agreement for the Army Tactical Missile System (ATACMS) in Germany, establishing dual-site manufacturing to accelerate missile stockpile replenishment for NATO allies. This transatlantic partnership shifts production from US-only lines to a European hub, leveraging Lockheed’s proven missile technology and Rheinmetall’s industrial capacity to scale output and reduce delivery timelines that previously spanned 2–4 years. The joint venture, with Rheinmetall holding up to 60% stake, will produce solid-fuel engines by 2026 and begin full missile assembly in 2027, targeting annual output of 600–800 ATACMS rounds alongside GMLRS, Hellfire, and PAC-3 missiles to meet urgent European and Ukrainian defense demands.
