One thing that\u2019s evident about President Donald Trump\u2019s proposal for the Golden Dome missile defense shield is that designing, deploying, and sustaining it will cost a lot of money, at least several hundred billion dollars, over the course of several decades.<\/p>\n

Beyond that, it\u2019s really anyone\u2019s guess. That doesn\u2019t sit well with some lawmakers, but the Republican-controlled Congress committed $25 billion in July as a down payment for new missile-defense technologies.<\/p>\n

The White House stated in May that Golden Dome will cost $175 billion over three years, but a new study from a center-right think tank concludes that it is simply not enough to develop the kind of multi-layer shield Trump described in a January executive order. It\u2019s also clear that it will take longer than three years to implement the full spectrum of defense capability envisioned for Golden Dome.<\/p>\n

\u201cThe capabilities this level of funding can buy fall far short of what the president promised, creating a multi-trillion-dollar gap between rhetoric and reality,\u201d wrote Todd Harrison, a senior fellow at the American Enterprise Institute.<\/p>\n

In announcing Golden Dome, the White House said the program must defend the US homeland against many types of aerial threats, including ballistic, hypersonic, and advanced cruise missiles, plus \u201cother next-generation aerial attacks,\u201d a category that appears to include drones and shorter-range unguided missiles.<\/p>\n

A program with few parallels<\/h2>\n

Harrison\u2019s paper, titled \u201cBuild Your Own Golden Dome,\u201d provides a framework for understanding the costs, choices, and tradeoffs facing the Pentagon as officials decide what exactly a homeland missile-defense shield will entail. And there are a lot of decisions to make as defense officials begin to define Golden Dome.<\/p>\n

\u201cIts cost hinges on the level of geographic coverage, the types and numbers of threats it must address, and the degree of resilience it is expected to achieve,\u201d Harrison writes. \u201cAs this analysis shows, even slight changes in these parameters can alter costs by hundreds of billions of dollars.<\/p>\n

,<\/p>\n

\u201cTo date, the administration has provided few specifics about what Golden Dome\u2019s capabilities will include,\u201d Harrison continues. \u201cAs long as these requirements remain undefined, it is fair to say that Golden Dome can cost as much or as little as policymakers are willing to spend.\u201d<\/p>\n

Gen. Michael Guetlein, who took over development of Golden Dome this summer, has completed a blueprint for the program, Bloomberg reported Wednesday. But the Pentagon declined to give any details on its scope or cost. That\u2019s a change of tone from two months ago, when Guetlein said he would talk about his plan for Golden Dome once he met a 60-day deadline to complete the framework, according to Bloomberg.<\/p>\n

In March, Guetlein said Golden Dome will require a \u201cconcerted effort\u201d and \u201cnational will,\u201d adding that the missile shield is \u201con the magnitude of the Manhattan Project,\u201d referring to the World War II initiative to develop the first atomic bomb.<\/p>\n

For now, the best estimates of Golden Dome total costs come from independent studies like the latest report from the American Enterprise Institute. All of the cost estimates, even the $175 billion price tag announced by the White House, far exceed the $35 billion cost of the Manhattan Project (adjusted for inflation).<\/p>\n

Cost projections for all but the narrowest Golden Dome architecture also surpass the total cost of the Apollo Moon program.<\/p>\n

Searching for answers<\/h2>\n

Harrison assessed six possible Golden Dome architectures, ranging from a low-end design that provides \u201climited tactical defense\u201d to a more expansive option offering a \u201crobust all-threat defense\u201d to the US homeland. The bottom line is that these architectures come with a wide range of estimated costs over the next 20 years.<\/p>\n

The least-expensive option would cost an estimated $252 billion (in fiscal-year 2026 dollars) beyond the Pentagon\u2019s current budget but would lack a key element explicitly spelled out in Trump\u2019s executive order calling for a multi-layer homeland missile-defense system: space-based interceptors.<\/p>\n

,<\/p>\n

Instead, the $252 billion option would include additional Patriot missile batteries and air-control squadrons, dozens of new aircraft, and next-generation systems to defend against drone and cruise missile attacks on major population centers, military bases, and other key areas.<\/p>\n

At the other end of the spectrum, Harrison writes that the \u201cmost robust air and missile defense shield possible\u201d will cost some $3.6 trillion through 2045, nearly double the life cycle cost of the F-35 fighter jet, the most expensive weapons program in history.<\/p>\n

\u201cIn his Oval Office announcement, President Trump set a high bar for Golden Dome, declaring that it would complete \u2018the job that President Reagan started 40 years ago, forever ending the missile threat to the American homeland and the success rate is very close to 100 percent,\u2019\u201d Harrison writes.<\/p>\n

The numbers necessary to achieve this kind of muscular defense are staggering: 85,400 space-based interceptors, 14,510 new air-launched interceptors, 46,904 more surface-launched interceptors, hundreds of new sensors on land, in the air, at sea, and in space to detect incoming threats, and more than 20,000 additional military personnel.<\/p>\n

No one has placed missile interceptors in space before, and it will require thousands of them to meet even the most basic goals for Golden Dome. Another option Harrison presents in his paper would emphasize fast-tracking a limited number of space-based interceptors that could defend against a smaller attack of up to five ballistic missiles, plus new missile warning and tracking satellites, ground- and sea-based interceptors, and other augmentations of existing missile-defense forces.<\/p>\n

That would cost an estimated $471 billion over the next 20 years.<\/p>\n

Supporters of the Golden Dome project say it\u2019s much more feasible today to field space-based interceptors than it was in the Reagan era. Commercial assembly lines are now churning out thousands of satellites per year, and it\u2019s cheaper to launch them today than it was 40 years ago.<\/p>\n

A report released by the nonpartisan Congressional Budget Office (CBO) in May examined the effect of reduced launch prices on potential Golden Dome architectures. The CBO estimated that the cost of deploying between 1,000 and 2,000 space-based interceptors would be between 30 and 40 percent cheaper today than the CBO found in a previous study in 2004.<\/p>\n

But the costs just for deploying up to 2,000 space-based interceptors remain astounding, ranging from $161 billion to $542 billion over 20 years, even with today\u2019s reduced launch prices, according to the CBO. The overwhelming share of the cost today would be developing and building the interceptors themselves, not launching them.<\/p>\n","protected":false},"excerpt":{"rendered":"
