Defense Contracting Fraud: Mischarging, Substitution and Testing
Defense contracting fraud includes labor mischarging across contracts, defective pricing, substituting counterfeit or noncompliant parts, falsifying required testing, and misrepresenting cybersecurity compliance. Department of Defense contracts are large, so recoveries and whistleblower awards in this category are substantial.
Labor mischarging is the classic case
On cost-reimbursable contracts the government pays for hours worked. Booking hours to a funded contract when the work was performed on a different program, on an overrun, or on internal research is straightforward fraud and it is documented in the timekeeping system.
The pattern is usually directed rather than individual. Employees are told which charge number to use, and the instruction is the evidence.
Parts, materials and testing
Defense specifications exist for reasons that show up later, which is why the government treats substitution and testing fraud seriously.
- Counterfeit electronic parts entering the supply chain
- Materials that do not meet specification substituted for qualified ones
- Country of origin misrepresentation under the Berry Amendment or Buy American requirements
- Required qualification or acceptance testing skipped
- Test results altered to show passing values
- Certificates of conformance issued without the underlying testing
Defective pricing
Under the Truth in Negotiations Act, contractors must provide cost or pricing data that is current, accurate, and complete when negotiating certain contracts. Withholding data that would have reduced the negotiated price is defective pricing.
Estimators, pricing analysts, and contracts staff are the people who know what was in the file and what was disclosed.
Cybersecurity compliance is now part of this
Since the Department of Justice created the Civil Cyber-Fraud Initiative in 2021, misrepresenting DFARS, CMMC, or NIST 800-171 compliance has become one of the most active theories against defense contractors.
The mechanism is the same as any other false certification. The contract required a security posture, the contractor certified it had one, and it did not.
Frequently asked questions
I was told which charge number to use. Does that make me complicit?
Following a timekeeping instruction while raising concerns is a common relator profile. Your own role affects your share rather than your eligibility, and documentation of the instruction is valuable evidence.
Can subcontractor employees file?
Yes. Subcontractors submit claims that flow to the government through the prime, and their employees are eligible relators.
What if the parts worked fine?
Delivering something that functions does not cure a false certification that it met specification. Where the specification exists for safety or reliability, the government treats substitution as material regardless of field performance.
