How to check or correct this record
The file sometimes leaves a certification out, and a newer one won't be in it yet. Self-reported business types are what the firm says about itself on SAM.gov; they aren't SBA certifications. This page doesn't show SBA's VetCert certification for veteran-owned firms; SBA's search below does.
Check or correct this record at the source: open its SAM.gov entry, or search UEI LYFDHU5GKHY3 () in SAM.gov's entity search (free sign-in) and in SBA's Small Business Search (formerly DSBS), which shows SBA certifications including VetCert. The business can update its details in its SAM.gov registration and its certifications at certifications.sba.gov.

Open contracts in Tandem Defense LLC's NAICS codes
338 open federal opportunities on SAM.gov use one of Tandem Defense LLC's NAICS codes and may be open to it: no set-aside, or, in the codes it is registered small under, a small business set-aside or one for a status it reports about itself on SAM.gov (service-disabled veteran-owned). Here are a few, those in its primary code first, then those in North Carolina, then the soonest due.
Confirm eligibility first. Tandem Defense LLC's service-disabled veteran-owned status is self-reported on SAM.gov, and this page can't confirm an SBA certification for it, so set-asides for it may be relevant but may not be open to it: SDVOSB and VOSB set-asides need SBA VetCert certification. SBA's Small Business Search shows a firm's current certifications.
