spacetoday.net: Pentagon dismisses $1.2 trillion cost estimate for Golden Dome

The general leading development of Golden Dome said a recent $1.2 trillion cost estimate for the system is inaccurate. Speaking at a conference Thursday, Gen. Michael Guetlein said the Congressional Budget Office's estimate released earlier this week is "not estimating what we're building." The Pentagon has not released details of its current Golden Dome architecture. Guetlein argued the report extrapolated from older defense acquisition models rather than the emerging commercial space manufacturing and launch systems his office expects to leverage. He acknowledged, though, that affordability remains the decisive issue for space-based interceptors and defended previous comments that the Pentagon will abandon the concept if it cannot be produced cheaply enough and at sufficient scale.
