Reverse Engineering & Source Development
Discuss an NSNWhen an NSN has no current approved source, or the original manufacturer is gone, Bernada reverse engineers the part from available drawings, samples, or technical data, and works to establish a new approved source.
Legacy systems don't stop needing parts just because the original supply chain disappeared—and neither do we.
We rebuild manufacturable definition from what remains, qualify a viable path to production, and improve parts where performance, reliability, or sustainment can be made better.

Part Improvement
From No Source to Approved Source
A disciplined path to recover the part, qualify production, and improve it where the mission benefits.
01
NSN Source Gap Assessment
Identify NSNs with no current approved source, obsolete OEMs, or broken supply chains that still support active legacy systems.
02
Technical Data Recovery
Collect and interpret available drawings, samples, specs, and residual technical data to reconstruct form, fit, and function.
03
Reverse Engineering
Reverse engineer the part into a manufacturable definition suitable for qualification, production, and sustainment.
04
New Approved Source
Work the approval path to establish Bernada—or a qualified manufacturing partner—as a new approved source for the NSN.
05
Prototype & Validation
Build and validate prototypes against dimensional, material, and performance requirements before production commitment.
06
Part Improvement
Where it strengthens the mission, improve materials, tolerances, coatings, or design details for better reliability and longevity.
Where We Focus
01
Obsolete OEM Recovery
Parts whose original manufacturers no longer exist or no longer support the NSN—rebuilt from drawings, samples, or remaining data.
02
No-Source NSNs
National Stock Numbers with no current approved source that still appear on active requisitions and legacy platforms.
03
Drawing & Sample Reconstruction
Reconstructing manufacturable definition when documentation is incomplete, outdated, or only a physical sample remains.
04
Source Approval Pathways
Establishing a new approved source through qualification, documentation, and production readiness aligned to customer requirements.
05
Sustainment-Critical Hardware
Mechanical parts that keep legacy systems operational when the original supply chain has collapsed.
06
Improved Replacement Parts
Upgraded materials, finishes, and design refinements that improve durability without breaking form, fit, or function.
Approach
Sustainment Through Engineering
“Legacy systems don't stop needing parts just because the original supply chain disappeared—and neither do we.”
Bernada treats reverse engineering as mission sustainment work: recover the definition, qualify a source, and improve the part when better performance or reliability serves the warfighter.
01
Start From What Remains
Drawings, samples, and technical data—however incomplete—are enough to begin reconstructing a viable manufacturing path.
02
Approve a Real Source
Reverse engineering only matters if it ends in an approved, producible source that programs can actually buy against.
03
Improve When It Helps
We don't stop at replication. Where materials, coatings, or design details can make the part better, we improve it.
Engagement
How We Work an NSN Gap
Bring us the NSN and whatever technical artifacts remain. Bernada assesses feasibility, reverse engineers the part, and drives toward a new approved source—while identifying opportunities to improve the design.
Who We Support
- Defense contractors & prime integrators
- Program offices & sustainment teams
- Depot & logistics organizations
- Manufacturing & qualification partners
Commitment
Parts When the Supply Chain Is Gone
Bernada exists for the NSNs that still matter after the OEM is gone. We reverse engineer, qualify, improve, and keep legacy systems supported.
