CMMC COMPLIANCE FOR ASSEMBLY OPERATIONS

CMMC Compliance for Assembly Operations

Defense assembly operations run on work instructions, test procedures, and serialized build records that are almost all CUI. We bring your assembly floor to CMMC Level 2 without breaking takt time.

Why Assembly Operations Companies Need CMMC Compliance

Assembly suppliers take kits of parts and turn them into finished defense assemblies — electronics modules, mechanical subsystems, weapons accessories, soldier-worn equipment, and more. The work instructions, assembly drawings, ATPs, and serialized build records that drive the line are almost all CUI.

The cybersecurity challenge in assembly is process integrity. A manipulated work instruction or tampered test result can produce defective product that ships undetected. CMMC Level 2 controls for configuration management, audit and accountability, and media protection directly address that risk.

Your customers — primes like RTX, Northrop Grumman, and L3Harris, and OEMs of tactical gear and electronic warfare systems — are pushing CMMC Level 2 flow-down onto new awards. Assembly suppliers that cannot demonstrate readiness will lose qualification.

We build CMMC programs tailored to assembly environments. We protect the MES and the ERP, segment the production network, and implement access controls that do not get in the way of a 10-second takt.

Which CMMC Level Do You Need?

The CMMC level you need is dictated by the information you handle under your DoD contracts. Here is how CMMC 2.0 breaks down for assembly operations.

Level 1

Foundational

  • 17 basic safeguarding practices from FAR 52.204-21
  • For contractors that handle Federal Contract Information (FCI) only
  • Annual self-assessment with senior-official affirmation in SPRS
  • No CUI in scope
Level 2 — Most Common for Assembly Operations

Advanced

  • All 110 controls from NIST SP 800-171 Rev. 2
  • Required for any contractor that stores, processes, or transmits CUI
  • Third-party C3PAO assessment every three years
  • The level most assembly operations will need
Level 3

Expert

  • All Level 2 controls plus selected NIST SP 800-172 enhanced requirements
  • Required for contractors on the DoD's highest-priority programs
  • Government-led DIBCAC assessment every three years
  • Applies to a narrow set of contractors

Most assembly suppliers handling CUI work instructions and ATPs will need Level 2. We will review your contracts and DFARS clauses with you at no cost to confirm.

Controlled Unclassified Information We Protect in Assembly Operations

Under NIST SP 800-171 and DFARS 252.204-7012, every one of these artifacts is typically CUI when tied to a DoD contract. Each one is in scope for CMMC Level 2.

Work Instructions & Build Procedures

Step-by-step assembly instructions, torque specs, and process controls tied to defense products.

Acceptance Test Procedures

ATPs and test result records for CUI products.

Serialized Build Records

As-built records and serial-number traceability for DoD end items.

Drawings & BOMs

Assembly drawings, BOMs, and AVLs received from the prime or OEM.

Calibration & Tool Records

Calibration data for torque drivers, test equipment, and gauges used on CUI products.

Non-Conformance Reports

NCRs, MRBs, and RCA documents tied to CUI assemblies.

Assembly Operations CMMC FAQ

When do assembly operations need CMMC?
Primes are flowing Level 2 down on new awards now. Start a readiness program if you plan to bid in the next 12-24 months.
What CUI do we handle?
Work instructions, ATPs, BOMs, AVLs, serialized build records, and NCRs tied to defense products are almost always CUI.
Can our operators access CUI?
Yes, with need-to-know access controls, training, and audit logging in place.
How long does it take?
Five to nine months for most mid-size assemblers.
Cost?
$60,000-$150,000 for readiness plus managed compliance and the C3PAO fee.
Will CMMC slow down the line?
Not when scoped correctly. Controls live on engineering and management workflows rather than the takt-time operations.
