Built for the South Bay Defense Cluster — From NASA Ames to Lockheed Martin Space
San Jose sits at the center of one of the densest aerospace and defense clusters in California. Lockheed Martin Space operates just miles from your facility. NASA Ames Research Center runs active programs in Moffett Field, right in your backyard. Your supply chain demands pursuing ITAR registration vendors who understand controlled hardware, tight schedules, and zero-defect delivery. RivCut is that shop. We machine mil-spec components for defense teams across the South Bay, with full traceability, DDTC-compliant handling, and tolerances down to ±0.0005 inches. No learning curve. No compliance surprises.

Precision CNC Machining for Defense Teams
Defense companies in San Jose 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 San Jose Defense Teams
San Jose defense programs demand precision, traceability, and speed. We deliver all three with every order.
Satellite & Space Structural Parts
We machine weapon mounts, trigger group components, and rail interface sections in aluminum 7075-T651 and 4340 steel. Every part ships with a material cert and heat lot traceability tied to your job number.
±0.0005" toleranceOptical & Sensor Housings
Defense optics programs in San Jose — including those tied to Lockheed Martin Space payloads — require housings with tight bore tolerances and precise surface finishes. We hold ±0.0005 inch tolerances on critical diameters and deliver Ra 32 or better on sealing surfaces.
±0.001" bore toleranceTactical & Electronic Enclosures
NASA Ames contractors and satellite integration teams need lightweight structural parts in titanium 6Al-4V and aluminum 2024. We 5-axis mill complex geometries with full CMM inspection reports included.
±0.002" EMI channelsWeapon System Components
Electronic warfare and signal processing hardware runs hot. We machine heat sink assemblies and cold plates in 6061 aluminum with internal channel geometries held to ±0.002 inches.
Heat lot certifiedDefense Robotics & Actuators
Many South Bay defense programs move from DARPA-funded prototype to LRIP fast. We scale from one part to 500 without changing your documentation package. One shop, one supplier code, continuous traceability.

Beyond those two anchors, San Jose hosts a dense layer of defense electronics and EW firms. Companies working in signal intelligence, radar, and directed energy have grown in the South Bay corridor.
Lockheed Martin — Largest Defense Prime
F-35 Lightning II, C-130J, and advanced missile systems programs drive massive demand for precision-machined structural and electronic components.
Raytheon Technologies — Missiles & Radar
Raytheon's Stinger, Tomahawk, and Patriot programs require thousands of precision-machined parts per unit from a wide supply chain.
Northrop Grumman — Advanced Systems
B-21 Raider, Global Hawk, and space systems programs. Northrop's supply chain spans hundreds of precision machining suppliers.
L3Harris, BAE Systems & Others
Defense electronics and comms primes rely on agile machining suppliers for housings, brackets, and assemblies across all program phases.
Why San Jose Defense Teams Work With RivCut
Union City is 30 miles north of San Jose on I-880. You can drop off hardware in the morning and pick up first articles the same afternoon if your schedule demands it. No freight broker. No cross-country shipping risk on controlled parts.
Pursuing ITAR Registration
We sit in the same Pacific time zone as your program office, your contracting officer, and your system integrator. When you send a DFM question at 8 a.m., you get a response before your stand-up meeting — not after lunch on the East Coast.
Mil-Spec Documentation
RivCut is registered with the Directorate of Defense Trade Controls under ITAR. All defense and controlled-technology work is handled exclusively by U.S. persons. We maintain export control procedures that hold up to audit. If your prime contractor requires supplier qualification documentation, we have it ready.
CMM Inspection Included
San Jose defense programs often run on compressed schedules tied to government fiscal calendars. We offer expedited lead times on standard geometries and keep common mil-spec materials — 7075, 4340, Ti 6Al-4V — in stock so we are not waiting on a distributor when your delivery date is firm.
Fast Prototype Turnaround
We also understand the semiconductor-defense crossover that makes San Jose unique. Applied Materials and KLA build equipment that feeds into defense sensor fabrication. When your program touches that supply chain, you need a machine shop that can handle both the defense compliance side and the semiconductor-grade surface finish requirements. We do both.
