Built for the Supply Chain Behind the C-130J and F-35 Center Wing
Lockheed Martin's Marietta plant on Dobbins Air Reserve Base builds the C-130J Super Hercules and the F-35 Lightning II center wing. That facility anchors a dense tier of defense subcontractors spread across Cobb County. If your shop or engineering team feeds that supply chain, your parts demand the same precision Lockheed holds its own production line to. RivCut is an pursuing ITAR registration CNC machine shop. We machine weapon system components, structural brackets, optical housings, and mil-spec hardware to tolerances as tight as ±0.0005 inches. We ship with full documentation your program office can use the day parts land on your dock.

Precision CNC Machining for Defense Teams
Defense companies in Marietta need parts that are exact, traceable, and compliant. A weapon mount that's out of spec affects reliability in the field. We machine aluminum 7075, 4340 steel, and titanium 6Al-4V to tolerances as tight as ±0.0005 inches. We are pursuing ITAR registration and handle controlled technology with proper export controls.
Shop Pursuing ITAR Registration
We are registered with the DDTC under ITAR. Defense and controlled-technology projects are handled by US persons only with proper export procedures.
Mil-Spec Materials
We machine aluminum 7075, 4340 steel, titanium 6Al-4V, and mil-spec alloys with full material certs and heat lot traceability.
Full Traceability
Every part gets a job number with records of material, programs, and operator sign-offs. Your program office can request records at any time.
What We Machine for Marietta Defense Teams
Marietta defense programs demand precision, traceability, and speed. We deliver all three with every order.
Satellite & Space Structural Parts
We machine aluminum 7075-T651 and 7050 plate to produce brackets, intercostals, and rib segments. These parts carry real load. We hold flatness and parallelism tolerances your receiving inspection will verify on a CMM.
±0.0005" toleranceOptical & Sensor Housings
Receiver components, trigger group parts, firing mechanism housings, and rail interfaces. We machine 4340 steel and 17-4 PH stainless with full heat lot traceability and material certs on every job.
±0.001" bore toleranceTactical & Electronic Enclosures
Tight bore tolerances for targeting pods and sensor packages. We machine titanium 6Al-4V and 6061 aluminum with surface finishes down to 32 Ra or better where your sealing surfaces require it.
±0.002" EMI channelsWeapon System Components
Milled pockets, precision-threaded inserts, and tight lid-to-body fits for avionics enclosures. We machine these in aluminum 6061 and 7075 with anodize-ready surface prep.
Heat lot certifiedDefense Robotics & Actuators
Jig tooling, fixture plates, and GSE adapter components for the Marietta plant floor or your own depot. We machine these from tooling plate and 6061 bar stock with same-day quoting available.
Surgical-grade precisionDefense R&D Prototypes
We hold ±0.0005 inches on critical features. Every defense job gets CMM inspection with a full dimensional report. First article inspection reports are available on request and formatted for your quality management system.

Why Marietta Defense Teams Work with RivCut
You are in Cobb County. We are in Union City, California. That distance sounds like a problem. Here is why it is not.
Pursuing ITAR Registration
Lockheed Martin's Marietta facility runs a disciplined production schedule tied to Air Force delivery windows. Your subcontract parts need to arrive on time with paperwork, not just in a box. RivCut ships with full material certs, CMM reports, and job traceability records every time. Your receiving dock gets what your program office needs to close out the line item.
Mil-Spec Documentation
We are pursuing ITAR registration with the Directorate of Defense Trade Controls. All defense work is handled by US persons only. Controlled technical data stays inside our facility under proper export procedures. You do not need to walk us through compliance basics.
CMM Inspection Included
Timezone difference works in your favor. You upload a CAD file at the end of your Atlanta-area business day. Our team in California reviews it that same afternoon Pacific time. You wake up with a quote waiting before your first meeting on Marietta Square.
Fast Prototype Turnaround
We do not require large minimum orders. Cobb County defense subcontractors often need five to fifty pieces to support a prototype build or a depot-level repair. We quote those jobs the same day and turn them in one to two weeks for most materials.
