The National Science Foundation, account by account.
NSF's five appropriation accounts from the FY2027 Budget Request, and the dominant Research & Related Activities account broken out by directorate. The FY2027 request consolidates the STEM Education directorate (EDU) into R&RA and eliminates the Social, Behavioral & Economic Sciences directorate (SBE) — shown exactly as the source states. $ in thousands.

MREFC (Major Research Equipment & Facilities Construction) is the lumpy, multi-year major-facilities construction account; its year-to-year swings reflect the construction phase of specific large facilities, not base program growth.
Research & Related Activities — by directorate ($ in thousands)
The R&RA directorate detail is published only for the FY2025 Current Plan and the FY2027 Request — the NSF Summary Table does not publish a FY2026 by-directorate split, so the FY2026 column is omitted here (flagged), never fabricated. SBE is proposed for elimination ($0) and EDU is consolidated into R&RA in the FY2027 request.

Mandatory funding — kept strictly separate ($ in thousands)

The Antarctic Research Vessel (ARV) line is $900.0M of new mandatory construction authority requested for FY2027 — the single reason the mandatory total jumps. The CHIPS for America Workforce & Education Fund, STEM Education funded through H-1B Nonimmigrant Petitioner Account receipts, and Donations make up the rest. Mandatory funding is never folded into the discretionary research headline.
