## Summary

Trump's [Golden Dome](/es/entity/interceptor-stocks) homeland missile shield is inching from vision to
contracts. The [Space Force](/es/entity/space-force) named 12 companies in April 2026 for space-based-
interceptor prototypes under OTA deals worth up to $3.2B; the FY26 appropriations bill carried
$13.4B for space and missile-defence systems. But cost and feasibility doubts dominate:
estimates run from $175B (White House) to $1.2T over 20 years (CBO) to $3.6T (AEI), and
industry press reports the program "spinning its wheels" on unresolved architecture.
Space Force Gen. Michael Guetlein conceded boost-phase intercept from space will not proceed
"if it is not affordable and scalable." Initial capability is targeted for 2028, full
architecture mid-2030s. The push tracks the [Chinese](/es/n/china-silo-launch-pads-xinjiang) and
[Russian](/es/n/russia-post-new-start-upload) threats it cites.

## By the numbers

- 12 — firms picked for space-based-interceptor prototypes (up to $3.2B).
- $13.4B — FY26 funding for space and missile-defence systems.
- $175B → $1.2T → $3.6T — White House / CBO / AEI cost estimates.
- 2028 — targeted initial capability; mid-2030s full architecture.

## Why it matters

Golden Dome is the most expensive missile-defence bet in decades, and its space-based layer
is the least proven. If it consumes [budget](/es/head/whose-money) without working, it crowds out the
[interceptor rebuild](/es/n/sm3-interceptor-production-surge) that the Iran war showed is the real
near-term gap.

## What to watch

- Whether boost-phase SBI prototypes pass affordability/scalability tests.
- FY27 appropriations: sustained funding or congressional pushback.
- How the cost estimate settles as the architecture firms up.

- **National Defense Magazine** (United States, en) — Argues that over a year after launch the program is 'spinning its wheels' on internal disagreement over architecture, with little concrete progress despite funding — a sceptical read from inside the defence-industrial press.
  > "More than a year on, internal misalignment over the architecture has left the flagship program with little to show."

### US mainstream
- **TIME** (United States, en) — Reports the CBO's $1.2T-over-20-years estimate and expert doubts the boost-phase, space-based concept can work as advertised, contrasting the White House's $175B figure with far higher independent projections.
  > "The CBO projects $1.2 trillion over 20 years — and analysts question whether the system can work as advertised."
