Lawmakers recently introduced legislation to fund President Donald Trump’s executive order calling for the creation of an “Iron Dome for America,” which provided new insight into how the government and military may go about upgrading the homeland’s air defense systems.

Sens. Dan Sullivan (R-AK) and Kevin Cramer (R-ND), both members of the Senate Armed Services Committee, introduced the Increasing Response Options and Deterrence of Missile Engagements Act last week. It would authorize slightly more than $19 billion for the creation of a new missile defense shield in fiscal 2026.
