GM Defense delivered an initial batch of PAC-3 MSE Patriot interceptor housing components to Lockheed Martin on Aug. 28, 22 days after the companies signed a contract on Aug. 6. The delivery, for work that typically takes months or longer, establishes GM Defense as a second supplier of Patriot missile housings alongside General Dynamics, The Wall Street Journal reported. Lockheed is using GM Defense's casting and machining capabilities as it expands munitions output amid depleted inventories tied to conflicts in Ukraine and the Middle East. The Pentagon directed Lockheed in January to lift Patriot production more than threefold to over 2,000 missiles annually before 2030 ends. Lockheed has committed $8 billion to $9 billion for PAC-3 MSE, THAAD and Precision Strike Missile programs, expanding facilities at more than 20 U.S. locations and increasing its combined production and warehousing footprint by nearly 50%. GM Defense and Lockheed plan to apply commercial manufacturing practices to additional munitions programs. GM Chief Executive Mary Barra said the company was on track for $700 million in defense revenue this year, while GM also negotiates with Lockheed over components for further missile programs.
