Frankenburg Technologies is a European defence technology company developing affordable, mass-manufacturable guided interceptor missile systems and the industrial capacity to produce them at scale. Founded in January 2024 and headquartered in Tallinn, Estonia, the company operates manufacturing and development sites across the United Kingdom, Latvia, Germany, Lithuania, Poland and Denmark. Its flagship product, the Mark I, is the smallest and lowest-cost guided interceptor missile ever live-fired, engineered for mass production using commercially available components and developed from concept to successful live-fire intercept in just 13 months.

Frankenburg's core value proposition is reducing the unit cost of interception by more than tenfold compared to legacy systems, addressing what it characterises as a fundamental cost, scale and replenishment crisis in Western air and missile defence. The company designs its missiles for integration across land, air and maritime platforms and supports sovereign production closer to operational need. In June 2026 it opened its Riga missile assembly site — billed as the first affordable mass-production missile factory in the world — targeting up to 100 missiles per day by end of 2026.

Key customers and partners include Airbus Defence & Space (whose uncrewed Bird of Prey interceptor autonomously engaged a drone using the Mark I in a live demo), BAE Systems, Roxel UK, Babcock International, ACUA Ocean, Milrem Robotics and Polska Grupa Zbrojeniowa (PGZ). The company has also received a UK Ministry of Defence contract under the LCADE programme. As of mid-2026 Frankenburg was reported to be finalising a Series B round of approximately €100 million at a potential unicorn valuation exceeding €1 billion.
