Cubic Corporation

Cubic Corporation was founded in San Diego in 1949 by Walter Zable and began operations in the early 1950s, and it has spent most of its history straddling two businesses that have almost nothing to do with each other on the surface: defense and public transit. That split is still how the company is organized today, into Cubic Transportation Systems and Cubic Defense, now formally called Cubic Mission and Performance Solutions. The transit side runs automated fare collection for major cities worldwide, including London's Oyster Card, New York's OMNY, Chicago's Ventra, and Sydney's Opal Card, and by the company's own account handles a large share of the global smart transit card market, processing billions of transactions a year through its Umo mobility platform. The defense side, which is what matters most to a directory like this one, centers on live training instrumentation, secure tactical communications, and C4ISR systems.

Cubic's best-known defense product is the P5 Combat Training System, an air combat training instrumentation suite that tracks aircraft position and timing with enough precision to replicate realistic air-to-air and air-to-ground engagements during live training exercises, used by the U.S. Air Force and allied air forces under a program that runs through 2032. On the communications side, the company's GATR TRAC terminal is a tactical, direct-downlink system built to talk to multiple satellite constellations across different orbits, moving data from space to the tactical edge without routing through a fixed ground station. Its DTECH line of rugged computing and networking hardware, including edge compute systems, supports forward-deployed units that need processing power and network connectivity without the benefit of a data center. Cubic's Nuvotronics subsidiary works at a different scale entirely, building advanced RF and millimeter-wave microelectronics using a proprietary PolyStrata manufacturing process, components that end up inside the satellite communications terminals and radar systems built by Cubic and its customers alike.

The company also runs a digital intelligence business handling full-motion video and geospatial data processing, and describes its overall defense strategy around what it calls assured multi-domain access, connecting air, maritime, and ground platforms even in contested or denied conditions. Cubic was a publicly traded company on the New York Stock Exchange for more than six decades before Veritas Capital and Elliott Management's private equity arm took it private in a 2021 acquisition, and it has operated as a privately held, PE-backed company since. It employs roughly 6,000 people worldwide across its two very different business lines. In March 2025, China imposed sanctions on Cubic over its defense work related to Taiwan, a reminder that even a company known partly for subway fare gates has real geopolitical exposure through its defense arm.
