Miami, Florida - President Donald Trump on Monday signed an executive order to start planning for an "Iron Dome" air defense system for the US similar to Israel's.

Trump ordered the defense secretary to submit within 60 days an implementation plan for the "next-generation missile defense shield" designed to guard against ballistic, hypersonic, and advanced cruise missiles, including by the development of space-based interceptors.

During the 2024 election campaign, Trump repeatedly promised to build a version of Israel's Iron Dome system for the US.

"Over the past 40 years, rather than lessening, the threat from next-generation strategic weapons has become more intense and complex," Monday's executive order said, citing unnamed adversaries' development of missile launch capabilities.

Trump had earlier told a Republican congressional retreat in Miami that the system would be built in the US.

Israel has used its "Iron Dome" system – funded in large part by the US – to shoot down rockets fired from Gaza and Lebanon.

"They knock down just about every one of them," Trump said at the Miami meeting. "So I think the United States is entitled to that."

The president signed several other orders related to the US military on Monday, including one setting the path for transgender people to be banned from the armed forces.
