What is the appropriation symbol for Military Construction, Air Force?

• A. 057Y3300
• B. 021Y2050
• C. 096X3123
• D. 096X3122

Answer: (A)

Appropriation symbols are a precise budgeting shorthand used to identify a specific funding line. They encode the type of funding, the department or component it belongs to, and the particular sub-account or program.

The symbol 057Y3300 is the one that uniquely designates Military Construction for the Air Force. The initial digits denote the broad category (Military Construction), the letter in the middle distinguishes the department or appropriation group within that category, and the trailing digits point to the exact sub-account or project within the Air Force’s Military Construction funds. This exact combination makes it the correct reference for Air Force Military Construction.

The other codes would map to different funding lines—either a different service or a different sub-appropriation within Military Construction—so they don’t represent the Air Force Military Construction appropriation. If you’re ever unsure, you can verify against the official DoD budget and accounting references, which list the exact symbol-to-program mappings.
