STS Systems Defense LLC also reported 9 subawards of its own worth $13M. These are the subawards under prime contracts for the agencies and codes RFPFinder tracks.
How do I find STS Systems Defense LLC's UEI or CAGE code?
STS Systems Defense LLC's UEI on its federal awards is E851ND24QMX9. Award records do not carry CAGE codes; search the UEI in SAM.gov's entity search to see the CAGE code and registration status.
Vendor totals add up the award records RFPFinder holds: federal contract awards from USAspending.gov for the agencies and codes behind open notices, and state and local awards from open-data contract registers and purchase-order files. They are not a vendor's complete government revenue, and a register that lists a contract ceiling or repeats a contract can overstate spend. Names are grouped across spellings ("Corp" and "Corporation"); each award links to its source record. Subcontracts are prime contractors' subaward reports on USAspending.gov for the prime awards behind the same agencies and codes, and GSA Schedule contracts come from GSA eLibrary's MAS contractor list; both are matched to vendors by name.
