Trump previously signed an executive order on the creation of the Iron Dome missile defense system in the US.
"Within 60 days of the date of this order, the Secretary of Defense shall: (a) Submit to the President a reference architecture, capabilities-based requirements, and an implementation plan for the next-generation missile defense shield," Trump's executive order says.
The architecture will include plans to defend against ballistic, hypersonic, and advanced cruise missiles; accelerate the deployment of hypersonic and ballistic space-based tracking sensors; and develop and deploy space-based interceptors capable of intercepting missiles during the boost phase, the document says.
The order emphasizes that the threat of a missile attack and other advanced air attacks "remains the most catastrophic threat facing the United States."
Earlier, on the day of his inauguration, Trump announced his intention to instruct the armed forces to develop and build the Iron Dome missile defense system to protect the country. Trump added that developing national defense would be one of the key priorities of his new administration.
