Trump stated that the "Iron Dome" system will be put into use within three years.

U.S. President Trump indicated that the "Gold Dome" missile defense system should be fully operational before the end of his term and said it would protect the United States from threats such as ballistic missiles, hypersonic vehicles, and advanced cruise missiles. "We will truly complete the project that President Reagan started 40 years ago," Trump stated in the Oval Office, referring to the unfinished space missile defense system plan of Ronald Reagan, which is widely known as "Star Wars." Given that much of the technology for the missile defense system has yet to be validated, particularly plans for space interceptors to intercept incoming ballistic missiles, Trump's pledge is an ambitious goal. The U.S. Congress is seeking to allocate $25 billion to initiate construction of the system, while Trump suggested that the total cost of the system could reach $175 billion. Trump has selected what he calls the system's "architecture," but did not specify details of that architecture, and stated that the system will encompass "next-generation technologies covering land, sea, and space." He appointed Space Force General Michael Guetlein to oversee the development of this system and noted that Canada wishes to participate in the program.
