The new US missile defense program could turn space into another battlefield, Foreign Minister Sergey Lavrov has cautioned
US President Donald Trump’s plans to build a multilayered Golden Dome missile defense system risk eroding the established nuclear and space security framework, Russian Foreign Minister Sergey Lavrov has warned.
First unveiled in January 2025, Trump’s initiative intends to build a layered shield against ballistic, hypersonic, and cruise missiles from America’s peer and near-peer adversaries, including Russia and China. The system relies on space-based interceptors designed to destroy threats in their boost phase, minutes after launch.
The White House projects the Golden Dome will cost $175 billion, but other estimates suggest much higher expenses, ranging from over $500 billion to $3.6 trillion over 20 years.
In a video address to participants of the Moscow Conference on Nuclear Non-Proliferation on Monday, Lavrov warned of risks associated with Washington’s efforts. “As a result of the destructive actions of the United States and its allies, the risks of the militarization of space and its transformation into a zone of conflict are noticeably increasing,” he said.
Lavrov singled out the Golden Dome program, which is scheduled to become operational by 2028, saying that it poses “a significant threat to strategic stability.”
Lavrov’s remarks echo a joint Russia-China warning in May 2025, when both countries argued that the Golden Dome could allow the US to neutralize a “radically weakened retaliatory strike” in case it decides to initiate a nuclear conflict.
Some analysts, however, have cast doubt on the feasibility of the Golden Dome project, as it hinges on space-based interceptors intended to destroy targets within an extremely narrow time window while requiring significant breakthroughs in sensor coverage and artificial intelligence technologies.
The Golden Dome bears some resemblance to President Ronald Reagan’s 1983 Strategic Defense Initiative – more commonly known as Star Wars – which was also built around space-based interceptors. The project was abandoned a decade later after up to $50 billion in spending, with no orbital weapon ever deployed due to enormous costs and insurmountable technological challenges.
The Soviet Union was alarmed by the initiative, branding it a first-strike tool and responding by ramping up its space defense program, which put additional strain on the already struggling economy.
