The scope here is Department-wide. DD Form 2490-23 — DD 2490-23, Network Planning and Configuration Data - Trunk Group Cluster Worksheet. This form has not been set up to work with a text-to-speech reader. Contact the DoD Forms Manager for further details if this access is required. — exists to Network Planning and Configuration Data - Trunk Group Cluster Worksheet, and it applies across the services rather than inside one. That is what the DD prefix encodes: joint issue, single edition, every branch and defense agency working from identical paper.
Authority: not stated prescribes it, not stated maintains it. Those two names settle most disputes about why the form is being asked for. Local commands add timing on top; the requirement itself comes from above them.
Use not stated, status not stated. Older printings circulate widely and lose their currency Department-wide the moment a new edition issues.
The set is PDF. Size: 1 pages, about 200 fields. Everything below refines that choice.
Default to fillable pdf, print only when you must. The fillable file stores what you type; the printable file is a blank picture. A Department form often travels further than a service form — scanned, emailed, forwarded to an agency that never saw the original — and typed text is what survives that.
Free download, every format. Do not fill the form in a browser tab — browser pdf viewers handle interactive fields inconsistently and discard entries on close.
What the form asks for
- Press this Reset button to clear the data from all fields.
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.
A number is a complete address in the DD series. Because the sequence is Department-level and not duplicated per service, there is nothing further to specify.
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.
Editions change when the prescribing directive is reissued, when the data collected changes, or when notice language is amended. None of that reaches you. Checking not stated at download is the entire defence, and it is cheaper than repeating a submission.
What is here is the blank form and a description of it. What is not here is legal guidance or any assurance about a particular filing — this page is not the issuing authority and does not speak for one. Those questions go to not stated, to your servicing administrative office, or to the authority identified in not stated.
