Israeli companies are preparing to participate in the United States' ambitious Golden Dome multi layered defense system, a project promoted by President Donald Trump with a projected budget ranging from $150 billion to $500 billion. The system aims to protect against advanced threats such as hypersonic missiles, drone swarms, and even engineered asteroids, but its exact structure and scope remain undefined. Israeli firms like Israeli Aerospace Industries and Rafael Advanced Defense Systems are positioning themselves to contribute advanced radar, interception, and laser technologies, though they will need to partner with American companies to compete for tenders. Major US defense contractors including Lockheed Martin, Raytheon, and Northrop Grumman are also vying for roles, while companies like SpaceX face uncertainty due to political disputes. Experts warn that the evolving nature of threats demands innovative solutions and international collaboration to ensure the system's effectiveness and cost efficiency.
