Federal contract history
| Fiscal year | Obligated, prime contracts |
|---|---|
| FY2024 | $532,133 |
| FY2025 | -$450 |
| FY2026 (incomplete) | $72,845 |
FY2026 is still incomplete and will rise until about early January 2027 as Defense data arrives: USAspending.gov publishes Defense contracts 90 days after they're signed.
These are every prime contract USAspending.gov records under UEI YF63PTPJVXA3, from its award search. For a company that is part of a parent company, USAspending's recipient page can show a different figure for a year, because it counts the company's own record and its parent's record separately.
A negative year means cuts to older contracts (de-obligations, often when work finishes under budget or is descoped) took off more than new awards added.
Its biggest federal customers since fiscal year 2024: Department of the Navy ($487,813), National Institute of Standards and Technology ($68,425), Department of the Air Force ($36,500) and National Oceanic and Atmospheric Administration ($11,790).

Subcontract work reported by primes
Prime contractors reported 2 subcontracts to it worth about $254,075 in the last five years, according to USAspending.gov. Primes only have to report subcontracts of $40,000 or more (since October 1, 2025; $30,000 before that), so smaller jobs are missing. Amounts are net of any cuts primes reported. None of this is in the prime contract figures.

Certifications and business types
No SBA certification (8(a), HUBZone or WOSB) in SAM.gov's public file (Nov 1, 2026).
- Veteran-owned (self-reported in SAM.gov)
SBA certifications let a business compete for set-aside contracts (set-asides explained). Check the current record on its SAM.gov entry.
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 YF63PTPJVXA3 () 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.
NAICS codes RH Systems LLC is small under
On its SAM.gov registration, RH Systems LLC meets the SBA size standard for these industries, so it can bid on small business set-asides that use them.
Open contracts in RH Systems LLC's NAICS codes
76 open federal opportunities on SAM.gov use one of RH Systems 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 (veteran-owned). Here are a few, those in its primary code first (none of these are in Arizona right now), then the soonest due.
Confirm eligibility first. RH Systems LLC's 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.
