Japan Poised to Join Trump's Golden Dome Missile Defence Initiative
Japan is preparing to announce its intention to join the United States' "Golden Dome" missile defence initiative next week, with sources indicating that Washington may seek Tokyo's assistance in missile production due to ongoing global conflicts. Prime Minister Sanae Takaichi is expected to confirm the plan during a leaders' summit with US President Donald Trump in Washington D.C. on 19 March, according to anonymous Japanese government sources who highlighted the sensitivity of the matter.
Golden Dome Project Aims for 2028 Launch
The Golden Dome project, unveiled last year with an ambitious target to go live by 2028, aims to enhance existing ground-based defences, such as interceptor missiles, by incorporating more experimental space-based components. These components are designed to detect, track, and potentially neutralise incoming ballistic and hypersonic missile threats from orbit. However, the initiative has shown little visible progress to date, and the specifics of Japan's involvement remain undefined.
The Yomiuri newspaper, which first reported Tokyo's plans on Friday, indicated that Japan hopes the initiative will provide a defence against new hypersonic glide weapons being developed by China and Russia. Tokyo anticipates that Trump may request Japan to produce or co-develop missiles to help replace stocks of US munitions depleted by the US-Israeli war on Iran, as well as its support for Ukraine, the sources said. Japan is still considering how to respond to any such request.
Historic Shift in Japan's Defence Exports
Japan exported a batch of surface-to-air Patriot missiles built under license to the United States late last year, marking a historic break from its long-standing ban on lethal weapons exports. The Trump administration is pushing defence contractors to step up production of missiles and other munitions that have been drawn down in recent years. Meanwhile, Tokyo is seeking to bolster its own munitions reserves to deter an increasingly assertive China and nuclear-armed North Korea.
Patriot interceptors have been critical in intercepting hundreds of Iranian ballistic missiles and drones fired at Gulf countries since the U.S. and Israel launched their air war against Iran earlier this month. Ukraine has also relied on Patriots to defend its energy and military infrastructure since Russia invaded it in 2022.
The Golden Dome project represents a significant step in international defence collaboration, with Japan's potential involvement signalling a shift in its defence posture and a deepening of US-Japan strategic ties. As global tensions rise, this initiative could play a crucial role in addressing emerging threats from adversarial nations.
