The FY2027 President's Budget requests $755.3M for Fusion Energy Sciences, within Energy's Non-Defense (Non-050) account. That is down 6.3% on the FY2026 figure of $805.7M, which is the enacted appropriation.

Bases are separate columns and are never summed into one figure.
Energy discretionary budget authority
From the OMB Public Budget Database — clean, summable, and the figure to cite for an agency total. It is the whole of Energy's discretionary request, not a total of the parsed lines above, and this page never adds the two together.
What this funds
Drives the science and technology foundation for a fusion energy source and a competitive U.S. fusion industry, supporting plasma research, multiple confinement concepts, world-leading experimental facilities, and the U.S. contribution to ITER.
Extracted from Energy Programs, p. 17. Verbatim; nothing here is paraphrased.
Contracts funded by this line
2 linked contracts. These are obligations — lifetime awarded money — and they are not comparable to the request above and are never added to it. No total is shown: an award linked to several lines is counted in full on each, so the sum would not be a fact.
| Contract | Vendor | Confidence | Obligated |
|---|---|---|---|
| 89233119CNA000063 last action FY2025 | GENERAL ATOMICS | Medium confidence | $180.0M |
| 89233124CNA000365 last action FY2026 | GENERAL ATOMICS | Medium confidence | $91.4M |

Linked contracts are a floor, not a census. Coverage is bounded by how distinctively a program is named and, for performer links, to RDT&E and Procurement — O&M and military construction publish no performers. Budget figures are FY2027 request dollars; contract figures are obligations. The two measure different things and must never be summed together.

Answers come from the figures on this page and nothing else. These dollars are parsed from Energy's Congressional Justification and are approximate — confirm anything that matters against the cited page.
