ARLINGTON, Va. — The Pentagon has increased its cost estimate for the Golden Dome missile defense initiative to $185 billion over the next decade, up from a previously reported $175 billion, as the program shifts more funding toward space-based capabilities.

Gen. Michael Guetlein, who leads Golden Dome for America, said March 17 that the additional $10 billion would be used to accelerate procurement of satellites and build out a space-based data network.

"We were asked to procure some additional space capabilities," Guetlein said at the McAleese Defense Programs Conference. "So we are at $185 billion for the objective architecture, which delivers way out into the 2035 time frame.
