About the Company

Zone 5 Technologies

Aerospace engineering and high-volume munitions production

Zone 5 designs and builds unmanned aircraft systems and low-cost missiles for defense, serving as a prime DoD contractor with vertical integration from concept to production. Its products, like the Rusty Dagger cruise missile, Paladin UAS for autonomous counter-drone missions, and White Spike for counter-UAS and precision strikes, are engineered for high-volume, low-cost production with modular avionics for fast fielding. It differentiates itself by a production-first approach that aims to cut unit costs and shorten development timelines, delivering a flight-ready system within about four months, and by controlling design and manufacturing in-house as a vertically integrated contractor; in 2026 it became a mostly-owned subsidiary of Kongsberg Defence & Aerospace. Its goal is to provide affordable, scalable munition and counter-UAS solutions for the DoD and allied forces.
