Donald Trump Announces an Ambitious Plan for a Fully American Iron Dome.
On January 19, 2025, during the rally preceding his inauguration in Washington, U.S. President-elect Donald Trump generated interest by announcing his plan to order the construction of a fully American "Iron Dome" once his second term begins. Inspired by the renowned Israeli missile defense system, this initiative, highlighted in the Republican Party's electoral platform, aims to create a "force field" around the United States.

Trump emphasized the project's national character, pledging that it would be developed and constructed within the United States. This plan raises critical questions regarding technical details, costs, and the technologies that might be incorporated. While the possibility of a system distinct from Israel's Iron Dome is not excluded, the proposal aligns with the goal of enhancing technological self-reliance and fostering innovation in the U.S. defense industry.
The Israeli Iron Dome, developed by Rafael Advanced Defense Systems with U.S. financial support, is globally recognized for its short-range missile defense capabilities. The mobile, all-weather system intercepts and neutralizes enemy projectiles, including rockets, artillery shells, and mortars. Equipped with an EL/M-2084 radar and Tamir interceptor missiles, it calculates threat trajectories in real time and engages only those likely to cause harm. With interception rates frequently exceeding 90%, the system has demonstrated its effectiveness in protecting civilian populations during multiple conflicts.
However, the Israeli Iron Dome has limitations. While highly effective against short-range threats, it offers only partial protection against long-range missiles, advanced drones, or hypersonic weapons. As a result, it is often supplemented by other systems, such as David's Sling and Arrow, to provide layered defense.
Trump’s proposed project aims to overcome these limitations by developing a system capable of addressing a broader range of threats, including emerging weapon technologies. This endeavor would require substantial investments to establish new production facilities and integrate advanced technologies. Additional challenges include ensuring compatibility with existing U.S. systems, such as the Patriot, THAAD, and Aegis, which form the backbone of the nation’s missile defense architecture. The future U.S. "Iron Dome" could leverage existing defense systems to create a comprehensive, multi-layered network capable of countering diverse threats.
The Patriot PAC-3 MSE (Missile Segment Enhancement) is a key component of U.S. air defense, designed to counter evolving threats like tactical ballistic missiles, cruise missiles, and low-orbit satellites. Equipped with an upgraded solid-fuel rocket motor, improved aerodynamic controls, and advanced guidance systems, this hit-to-kill missile ensures total target destruction. Operating at speeds of Mach 5, it has a range of 35 kilometers and an interception altitude of 15 kilometers. Each launcher, mounted on a mobile platform, carries up to 16 missiles, enabling rapid and effective responses to complex threats, including those employing electronic countermeasures.
The THAAD (Terminal High Altitude Area Defense) system is specifically designed to intercept and destroy ballistic missiles during their terminal phase, both within (endoatmospheric) and outside (exoatmospheric) the atmosphere. Highly mobile and transportable, the system uses hit-to-kill technology, neutralizing threats with kinetic energy to minimize risks associated with weapons of mass destruction. A single THAAD battery includes up to nine mobile launchers, each carrying eight missiles, an AN/TPY-2 X-band radar with a detection range of 1,000 kilometers, and command-and-control vehicles. THAAD operates seamlessly alongside systems like the Patriot and Aegis, ensuring robust protection for military forces, strategic infrastructure, and civilian populations.
The Aegis combat system, at the core of Aegis-equipped destroyers, provides unparalleled air defense and ballistic missile interception capabilities. Paired with the AN/SPY-1D phased-array radar, it can detect and track multiple aerial threats over 300 kilometers. Aegis-equipped destroyers are armed with Standard Missiles (SM), including SM-2, SM-3, and SM-6, capable of intercepting threats ranging from aircraft to medium-range ballistic missiles. Incorporating the Aegis system into the proposed U.S. Iron Dome could offer a formidable shield for critical locations and infrastructure.
The U.S. is also heavily investing in high-powered lasers and directed energy weapons to counter drones and missiles. These technologies could complement the system by providing cost-effective and rapid solutions for neutralizing specific threats.
Advanced radars, such as the Sentinel A4, used for aerial threat detection and surveillance, could play an integral role in the proposed Iron Dome. These radars are critical for real-time detection, tracking, and engagement of threats, ensuring optimal system performance.
Integrating the Iron Dome with the Integrated Battle Command System (IBCS) could further enhance coordination between different defense platforms. Through real-time data sharing, this would improve interception speed and accuracy.
The proposed Iron Dome could serve as a catalyst for the U.S. defense industry, promoting strategic independence and reinforcing the country’s position on the global stage. However, its success will depend on the ability to develop a system that is efficient, adaptable, and economically sustainable. This initiative could also redefine global standards in missile defense.
Trump’s announcement marks a potential turning point in the evolution of U.S. defense technologies. This project represents a critical step in safeguarding the nation against adversaries such as China, Russia, and North Korea, whose advancements in ballistic and hypersonic missile technologies pose significant threats. By addressing these strategic challenges, the U.S. Iron Dome could provide a vital defensive edge while strengthening alliances with key partners who share similar security concerns.
