Lockheed Martin and Diehl Defence have officially announced a strategic partnership to strengthen the global supply chain for the highly sought-after Patriot Advanced Capability-3 (PAC-3) Missile Segment Enhancement (MSE) interceptor. The partnership was formalized through a Memorandum of Understanding (MoU), signed at the annual Association of the United States Army (AUSA) exposition. This new collaboration aims to bolster the resilience and scalability of the PAC-3 MSE production pipeline, ensuring a steady and reliable supply of this essential air defence system, particularly as global threats evolve.
The PAC-3 MSE is a cutting-edge missile defence system, designed to counter a wide array of airborne threats, including ballistic missiles, cruise missiles, and hypersonic weapons. With its advanced capabilities, the PAC-3 MSE has become an integral part of national defense strategies for countries around the world. As demand for this advanced interceptor continues to rise, particularly in light of increasing geopolitical tensions, both Lockheed Martin and Diehl recognize the critical need to expand and diversify the system’s production and supply channels.
Addressing Growing Global Demand for Air Defence
The MoU between Lockheed Martin and Diehl Defence reflects a shared vision of strengthening supply chain management and ensuring that production can be rapidly scaled to meet rising global demands. Torsten Cook, Senior Vice President for Ground-Based Air Defence at Diehl, emphasized the importance of creating a flexible and multi-source supply chain. He stressed that in times of crisis—such as the ongoing war in Ukraine—being able to quickly ramp up production and get more systems into the market is crucial.
"It’s essential to have a dual-source or even a third-source supply chain management capability," Cook explained during an interview with Breaking Defence. "This flexibility allows us to increase production capacity quickly and ensure that more material is available on the market, especially in Europe, where it can help support Ukrainian civilians and forces defending against Russian aggression.".
By diversifying the sources of key components, both companies aim to ensure that production is not disrupted by potential supply chain bottlenecks, geopolitical challenges, or other unforeseen events. As the PAC-3 MSE becomes increasingly vital to international defence operations, particularly in Europe and the Indo-Pacific, the two companies are aligning their efforts to address future supply shortages before they occur.
Prioritizing European Components for PAC-3 MSE Production
One of the key elements of the collaboration is a focus on sourcing European components for the PAC-3 MSE. By tapping into European manufacturing capabilities, Lockheed Martin and Diehl seek to create a more localized production network that enhances supply chain resilience within Europe. This will also have the added benefit of ensuring that European nations are better positioned to support each other, particularly in the context of shared defence efforts like NATO operations.
Diehl Defense, a German defence contractor with extensive experience in missile defence systems, will play a central role in sourcing and manufacturing the necessary components for the PAC-3 MSE. According to Cook, Diehl's focus will be on the integration of “European components,” further solidifying the collaboration between the U.S. and European defence industries.
“By ensuring that key components of the PAC-3 MSE come from European manufacturers, we are not only increasing our capacity to meet global demand but also supporting the European defence ecosystem, which is crucial in these challenging times,” Cook remarked.
Strengthening Local Production Footprints in Germany
As part of the partnership, there are discussions about Lockheed Martin establishing a more robust local footprint in Germany. This would involve investing in the production and supply of essential materials, such as thermal batteries, which are critical to the operation of the PAC-3 MSE and several other advanced defence systems.
Diehl’s subsidiary, Eagle Pitcher, currently provides thermal batteries for the PAC-3 MSE, as well as for other missile systems like the Stinger, IRIS-T, and the Evolved SeaSparrow Missile (ESSM). By working together to localize the production of these vital components, the companies aim to further streamline the production process and ensure that supply chain disruptions—whether due to geopolitical factors, manufacturing issues, or demand spikes—are minimized.
Cook hinted that Lockheed Martin’s participation in this local production effort could be a significant next step. "Lockheed could become a key partner in establishing a local footprint in Germany, focusing on the supply of thermal batteries and other critical components," he noted. This would not only enhance production capacity but also demonstrate Lockheed's commitment to working closely with European partners to strengthen regional defence capabilities.
US-Germany Partnership Within the Global PAC-3 MSE Ecosystem
The United States and Germany are among the 17 partner nations that have chosen the advanced Patriot missile defence system, including the PAC-3 MSE interceptor, as part of their defence arsenals. The expanded collaboration between Lockheed Martin and Diehl Defense underscores the growing importance of international partnerships in the production and deployment of advanced defence technologies.
Lockheed Martin, a major player in the U.S. defence industry, continues to lead the development and production of the PAC-3 MSE. As part of its ongoing efforts to meet international defence needs, Lockheed secured a $9.8 billion contract in September 2023 for the production of nearly 2,000 PAC-3 MSE interceptors, along with associated hardware. This contract highlights the growing global reliance on the PAC-3 MSE as a core element of air defence systems.
The U.S. and Germany are not alone in their use of the PAC-3 MSE. Countries across the world have recognized the system’s effectiveness in defending against increasingly sophisticated missile threats, making it a cornerstone of modern missile defence. The cooperation between Lockheed Martin and Diehl Defense serves as a model for how nations and companies can work together to ensure that these critical defence systems remain available and operational in the face of evolving global threats.
Boeing's Role in the PAC-3 MSE Supply Chain
In a related development, Boeing announced it had been awarded a $2.7 billion multiyear contract to supply additional PAC-3 seekers, which are integral to the guidance and targeting systems of the interceptor. The contract, which covers the production of more than 3,000 seekers over several years, will help ensure that the PAC-3 MSE can maintain its operational effectiveness.
Boeing’s role in this process highlights the complexity and collaboration involved in producing such a sophisticated defence system. Boeing, Lockheed Martin, and the U.S. Army are working together to increase production rates and meet new targets for the PAC-3 interceptor. This collaboration is essential to ensure that the Patriot system remains capable of defending both military and civilian infrastructure worldwide.
“Scaling up seeker production is vital to ensuring that the PAC-3 interceptor continues to provide reliable defence for service members, civilians, and critical infrastructure,” Boeing said in its statement. "As global threats continue to grow, the need for advanced air defence systems like the PAC-3 is more critical than ever."
The Future of the PAC-3 MSE and Global Air Defence
As geopolitical tensions persist and missile threats become more sophisticated, the demand for the PAC-3 MSE is expected to rise. Lockheed Martin and Diehl Defense's partnership represents a proactive step in ensuring that the system’s supply chain remains strong, adaptable, and capable of scaling to meet global needs.
With the increasing focus on securing European airspace, the collaboration between U.S. and European defence contractors underscores the importance of cross-border cooperation in maintaining a competitive edge in defence technology. The efforts to localize production, source critical components from European manufacturers, and invest in regional manufacturing capabilities demonstrate how defence companies are responding to the growing demands of global security.
The partnership between Lockheed Martin and Diehl Defense, along with Boeing’s contributions to seeker production, illustrates how industry leaders are coming together to ensure that the PAC-3 MSE remains a cornerstone of global missile defence for years to come. The continued expansion of the system’s supply chain will be crucial in meeting both current and future defence challenges.
