DD Form 1921 is a Department of Defense form, not a service form: Cost Data Summary Report, used to Cost Data Summary Report. 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.
not stated is the prescribing publication and not stated the office responsible for the document. Deadlines belong to local implementing guidance, not to either of those, so a submission date is a question for the receiving office.
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.
The set is none published here. Size: unknown pages, about unknown fields. Everything below refines that choice.
Fillable pdf is the default choice. Its boxes hold typed entries inside the document; the printable release is a static image of the same page with no interactive layer. Since DD forms routinely cross between services and agencies before they are filed, typed entries matter more here than on a form that stays inside one office.
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.
Field-level questions go to the printed instructions, then to not stated, which is authoritative.
Send it as not stated or local guidance specifies. Save a copy. Cross-service and cross-agency routing is normal for Department forms, and a lost original outside your own organization is harder to chase down.
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.
Prefix before number. A DA citation and a DD citation in the same instruction point at separate systems — one Army, administered by an Army proponent, one Department-wide under not stated — and there is no correspondence between them at any number.
Three drivers of revision: directive reissue, altered collection requirements, updated statutory notice text. No notification accompanies any of them, so download fresh and confirm not stated rather than reusing an archived file.
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.
