The Virginia spacecraft supplier spent 13 years turning radiation-tolerant power, batteries and computers into configurable products. Its March 2026 sale to Trident shows what happens when a small engineering shop makes the least glamorous parts of a satellite easier to buy.

Zero-Error Systems (ZES) is a Singapore deeptech semiconductor company and Nanyang Technological University spin-off that builds radiation-hardened integrated circuits, radiation-tolerant system-on-modules, and irradiation testing services. Its patented radiation-hardened-by-design technology protects low-cost commercial-off-the-shelf (COTS) electronics from radiation effects such as single-event latchup, letting satellite and space-system makers achieve space-grade power reliability and data integrity at a fraction of traditional rad-hard cost.
VORAGO Technologies is an Austin, Texas fabless semiconductor company that designs radiation-hardened and extreme-temperature microcontrollers and microprocessors for aerospace, defense and industrial systems. Its patented HARDSIL process hardens standard commercial silicon against radiation and heat using conventional high-volume manufacturing, letting spacecraft, satellites and downhole tools run Arm Cortex-based compute in environments that would destroy ordinary chips.
