Before President Donald Trump’s melodramatic uncover of the "Golden Dome" rocket defence task connected Tuesday, the connection wasn’t adjacent connected the radar of galore lawmakers connected Capitol Hill.
Several senators told Fox News Digital they had received nary briefing connected the initiative’s costs – and immoderate hadn’t heard of it astatine all.
"I don’t enactment blank checks. I haven’t seen the outgo figures," Sen. John Kennedy, R-La., told Fox News Digital.
Two elder members of the Senate Appropriations Defense Subcommittee, 1 Republican and 1 Democrat, asked, "what’s Golden Dome?" successful effect to questions astir the task Trump commissioned successful January.

Trump’s sweeping program – pitched arsenic an American mentation of Israel’s Iron Dome – carries an ambitious terms tag and timeline. He’s floated a $125 cardinal estimated cost and says it could beryllium built successful 3 years, by the extremity of his term. A authorities backing bundle moving done Congress, dubbed the One Big Beautiful Bill Act, includes $25 cardinal to jumpstart the project.
But defence experts and adjacent immoderate Republican allies expect the outgo to beryllium overmuch higher.
"This is not going to beryllium a $25 cardinal oregon $35 cardinal project. It volition apt outgo successful the trillions if and erstwhile Golden Dome is completed," said Sen. Tim Sheehy, R-Mont., who announced plans to signifier a Golden Dome Caucus during a caller Washington Times defence manufacture lawsuit earlier this month.
Sheehy warned that simply scaling up Israel’s Iron Dome to support the U.S. is "a fundamentally antithetic technological proposition."
"The challenges don’t standard linearly with the size of Israel, which is the size of New Jersey," helium added.
The nonpartisan Congressional Budget Office (CBO) has estimated the task could outgo astir $500 cardinal – though immoderate judge adjacent that fig is apt excessively low.
CBO estimated that the space-based interceptors information of the dome could outgo astatine slightest $161 cardinal but up to $542 billion. But it didn't relationship for immoderate ground-based interceptors successful that cost.
"I’ve been 34 years successful this business, and I’ve ne'er seen an aboriginal estimation that was excessively high," said Space Force main of abstraction operations Gen. Chance Saltzman. "We don’t ever recognize the afloat level of complexity until you’re really successful execution, doing the elaborate planning."

Some Republican lawmakers suggest the imaginable benefits outweigh the monolithic spending required.
"It mightiness precise good forestall a war," Sen. Mike Rounds, R-N.D., said. "When we speech astir spending billions connected defense, that is tiny compared to 1 azygous large warfare – not lone successful trillions of dollars, but successful bloodshed."
Once a rocket is launched toward the U.S. homeland, the Golden Dome strategy aims to observe it, and orbital systems would purpose to deed the rocket during its "boost" phase, either with a laser oregon a kinetic interceptor. Otherwise, ground-based systems could deploy to sound it disconnected its path.
Others noted competing defence priorities.
"That’s gonna beryllium a long, drawn-out process, and it’s gonna outgo a batch of money," said Sen. Tommy Tuberville, R-Ala. "Right now, we’re redoing our rocket silos… we’re transitioning to antithetic types of warfare. If we’re gonna bash [Golden Dome], we bash it the close way."
Supporters of the program reason that technological advances person dramatically lowered the outgo of rocket defense, capable to perchance flip decades-old strategical assumptions.
Chuck DeVore, a defence adept astatine the Texas Public Policy Foundation and erstwhile Reagan medication official, said the aged logic – that it’s ever cheaper to physique violative missiles than defenses – whitethorn nary longer apply.

"That calculation is changing now," DeVore said. "With low-cost orbit launches and inexpensive electronics, it whitethorn really beryllium little costly to support against atomic missiles than to physique them. If that’s the case, we’re astatine a genuinely revolutionary inflection point."
DeVore besides warned that traditionalists successful the defence constitution whitethorn propulsion back.
"You’re going to spot radical defending the presumption quo," helium said. "They’ll accidental we request that wealth for much accepted defence – much divisions, much pitchy fighters, possibly different craft carrier."
Still, DeVore argued that a homeland rocket defence strategy is overdue.
"The quality to genuinely support the homeland and prevention American lives is amended than communal assured demolition – particularly successful an property of atomic proliferation wherever we can’t ever beryllium definite wherever the menace is coming from."

Sen. Markwayne Mullin, R-Okla., agreed connected the project’s importance, adjacent arsenic helium said helium hadn’t been briefed connected the outgo and needs of the project.
"I deliberation it’s the astir important happening we could bash to support our homeland safe."
