This was reported by Japanese government sources cited by Reuters, pointing out that Prime Minister Sanae Takaichi plans to formally communicate the country’s intention during a bilateral meeting scheduled for March 19 in Washington.
In parallel, and in a context of pressure on US arsenals due to the simultaneous conflicts in the Middle East and Ukraine, Japan anticipates the possibility of industrially supporting Washington to increase the production of interceptor missiles. This scenario occurs after Tokyo exported interceptors of the MIM-104 Patriot system manufactured under license to the United States in 2025, in a fact that marked a significant change with respect to the traditional restrictive Japanese policy on arms exports.
He Golden Dome project seeks to expand the US missile defense architecture by integrating existing ground systems with more advanced sensors and interception platforms. Among the systems currently deployed by the Pentagon is the Ground-Based Midcourse Defense, designed to intercept intercontinental ballistic missiles during the middle phase of their trajectory using ground-based interceptors. Another key layer is the Terminal High Altitude Area Defense (THAAD), developed to destroy ballistic missiles in the terminal phase of their flight at high altitude, expanding coverage against regional threats. On a smaller scale, the Patriot system—used by numerous allies—intercepts tactical missiles, drones and hostile aircraft in the final leg of their approach.
These systems are supported by a network of early warning radars and space sensors that make it possible to detect launches, follow the trajectory of the projectiles and coordinate the interceptor response. The multi-layer architecture seeks to intercept missiles in different phases of flight, increasing the probability of neutralizing the threat before it reaches its target.
According to an analysis published by Politico, the project is still far from operational implementation. Although the US Congress approved about $23 billion for the initiative, the Pentagon has not yet begun deploying the network of sensors and interceptors due to delays in the release of funds and the complexity of the system.
The initiative, however, has also generated criticism from other powers. officials of China y North Korea have warned on different occasions that the development of interceptors and orbital sensors could accelerate the militarization of space and increase the risk of turning it into a new domain of strategic confrontation.
