Headquartered in Westfield, Indiana, Ball Systems builds turnkey automated test systems, build-to-print assemblies, and ground support equipment for aerospace and defense primes, OEMs, and government programs. Trusted by Boeing, the U.S. Air Force, the U.S. Navy, Honeywell, L3Harris, Collins Aerospace, and Rolls-Royce (to name a few), our programs range from a single custom system to thousands of assemblies a year.
Our capabilities span the full range of aerospace and defense test requirements: automated test systems (ATS), build-to-print assemblies, custom test systems, National Instruments PXI-based platforms, ground support equipment (GSE), avionics test solutions, electrical load boxes, control panels, portable test systems, wire harnesses, and printed circuit assemblies (PCAs).
For example, Ball Systems is proud to support NASA's groundbreaking Artemis program through our aerospace and defense manufacturing partners.

We regularly support aerospace and defense primes, OEMs, and government programs on export-controlled work. Our compliance infrastructure, which includes ITAR registration, CMMC Level 1, and ISO 9001 certification, is designed to meet the documentation and audit requirements these programs demand.
We build a full range of electrical and electronic test systems for aerospace and defense applications, including automated test systems (ATS), build-to-print assemblies, National Instruments (NI) PXI-based platforms, ground support equipment (GSE), avionics test solutions, electrical load boxes, control panels, portable test systems, wire harnesses, and printed circuit assemblies (PCAs).
If it requires precision electrical or electronic test capability, we've likely built it. For example, our work is a part of the Artemis program at NASA, which is sending astronauts to explore and land on the moon again, alongside creating the first crewed mission to Mars.
It's one of the most common challenges we solve. Aging test equipment with obsolete components, discontinued parts, or outdated software creates real program risk. Ball Systems has extensive experience assessing legacy systems and delivering modern replacements that maintain functional continuity while meeting current compliance and performance standards.
There isn’t one. Ball Systems supports programs ranging from a single custom system to thousands of assemblies per year. Our build-to-print model is specifically designed for low-volume, high-complexity work — the kind of program where most contract manufacturers struggle to deliver consistent quality at low quantities.
When requirements shift, your dedicated engineer is already embedded in the project and can respond without losing ground. We're direct about what changes mean for scope, timeline, and cost before they become surprises.
Ball Systems is a small US-owned business. Headquartered in Westfield, Indiana, with a field office outside Detroit, we've operated in Central Indiana for over 60 years. All design, manufacturing, and test work is performed domestically.
