President Trump issued an executive order regarding the construction of a "next-generation missile defense shield" similar to the "Iron Dome"

President Donald Trump has ordered the Pentagon to develop plans for a high-tech missile defense shield for the United States. He dubbed the effort "Iron Dome for America" -- a reference to a highly successful system employed by Israel -- but the threats to the US homeland that Trump wants to counter differ from those faced by Washington's close ally.

For more than 60 years, the military has launched reconnaissance, communications, and missile warning satellites into orbit. Trump's executive order calls for the Pentagon to come up with a design architecture, requirements, and an implementation plan for the next-generation missile defense shield within 60 days.
