Trump's order establishing an Iron Dome for America includes a wider focus to defend the homeland from air and missile attacks from peer adversaries.

Authorities in Moscow on Friday criticized U.S. President Donald Trump's plan to build an "iron dome" missile defense system in the United States, saying it risked turning space into an arena of "confrontation.

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.

Such defense systems are extremely costly” with “their effectiveness often being questionable,” one expert said.

Read about a new executive order that calls for the deployment of a next-gen missile defense shield to safeguard against foreign aerial attacks.

An executive order said the United States faced a “catastrophic threat” from advanced aerial weapons. But a defense system like Israel’s may not be feasible in the country, which is more than 400 times larger.

President Donald Trump’s order to implement an “Iron Dome for America” missile defense is drawing interest from at least one major defense contractor with missile-related operations in Huntsville.

Donald Trump is busy planning American defense from hostile nations for the near future, and has already issued an executive order to build an Iron Dome to defend the United States border regions from enemy missile incursions.
