Spectra Aerospace & Defense is a trusted and growing platform of C5ISR companies – CALCULEX, Galleon Embedded Computing, and ArgonFDS - bringing over a half-century of rugged, mission-ready, battle-tested experience to bear in aerospace and defense applications. Spectra companies are all leading designers and producers of highly-engineered avionics and electronics products. They have the proven experience, long-standing relationships, and engineering resources needed for leading-edge platforms and complex, long-term military programs in support of national security requirements around the world. Spectra Aerospace & Defense was formed in 2021 to bring customers a more diversified product offering for the C5ISR sector, broader and deeper product and technology knowledge, and an integrated, open-architecture systems capability, all from a group of companies with decades of proven performance. In conjunction with the formation of Spectra, the well-established brands, Argon and FDS Avionics, were combined into a single operating company, “Argon FDS.” Galleon Embedded Computing joined the Spectra family in August 2021. Spectra Aerospace & Defense is a portfolio company of Vance Street Capital.
