DD Form 1597 is a Department of Defense form, not a service form: DD Form 1597, Contract Closeout Check-List, April 2000, used to Contract Closeout Check-List. The DD prefix is the operative fact. It means one blank serves every military department — Army, Navy, Air Force, Marine Corps, Space Force, Coast Guard under Defense jurisdiction — plus the defense agencies and combatant commands. No branch variant exists.
Requirement traces to not stated; the form belongs to not stated. Everything about schedule sits below that in local instruction, which is where to ask if a date matters.
Current edition is not stated, carried as not stated. Check that against any copy you already hold before doing anything else — Department-level revisions land everywhere simultaneously, so a stale file is stale across the whole Department.
Formats: PDF. Length 1 pages, approximately 123 entries. Pick on the basis of how you will complete it.
Take the fillable pdf unless you have a reason not to. Fillable means the boxes are real fields that accept typed text and retain it in the file. Printable means a flat blank — no fields, printer and pen only. The difference is not cosmetic: one produces a record that reproduces cleanly through scanning and forwarding, the other depends on penmanship.

Verify the edition before the first keystroke. The date on the form face should read not stated. If it does not, discard the file. Field numbering shifts between editions, and on a DD form the new layout reaches every receiving office in every service at once — there is no lag during which the old version is still normal somewhere.
Fill top to bottom. Identification, then substance, then certification — lower fields commonly derive from the header, and completing out of order produces internal contradictions a reviewer will catch.
Complete every field, N/A where an item does not apply, dates exactly as the form prescribes. A DD form crosses service lines, and a convention obvious in one branch is not obvious in the next.
Privacy Act Statement first, personal entries second. It names the authority for the collection, what the data is for, who else routinely sees it, and whether you have to answer at all.
Sign last, in ink or with a credentialed digital signature. A typed name in a signature field certifies nothing. CAC-based signing is the usual electronic method where the receiving system supports it. Date the block immediately — unsigned and undated certifications account for a large share of returns.
Final pass, against the standing defect list: superseded edition, empty mandatory fields, handwriting illegible after scanning, non-conforming dates, missing signature or date. For anything ambiguous in a specific field, the form's own instructions come first and not stated controls where the two differ.
Route it where not stated or local procedure directs, and keep a copy first. On a Department form the receiving office is frequently outside your own chain — another service, a defense agency, a joint command — which makes recovering a lost original slower than it would be internally.
Related forms are found by number alone. The DD sequence is one unified Department-wide series, so a cited number resolves to exactly one document with no branch qualifier needed.
Where a procedure cites both a service form and a DD form, the two are unconnected. Service numbering answers to a service proponent, DD numbering to not stated or another Department office, and the two sequences were never aligned. Matching numbers mean nothing whatever.
Revision follows directive changes, changed data requirements and amended notice language, unannounced. Verify not stated each time rather than trusting a saved copy — the cost of the check is seconds.
This page publishes a Defense document and explains its contents. It does not advise, does not rule on applicability, and determines nothing about how a completed form will be treated. Direct such questions to not stated, to the servicing personnel office, or to the office designated in not stated.
