Our company was founded in 1964 as Racal Communications, Inc. Back then, we focused on the production and fielding of HF receivers for the US defense market. Today, we operate as Thales Defense & Security, Inc. (TDSI), and our business has since grown to include four unique business divisions and three subsidiaries. Our vast, expanding technology portfolio spans air, land and sea operations, while our in-house, full lifecycle engineering to production capabilities specialize in delivering rugged, mission critical defense technologies that enhance the Warfighter’s operational advantage in combat. TDSI is proud of our first-to-market legacy, and we continue to build upon our rich heritage of delivering world class products and services to government and commercial customers across the globe.
