Mach Industries demonstrates autonomous Viper strike platform to Lithuanian and Estonian forces

Mach Industries demonstrated its Viper autonomous strike platform to Lithuanian and Estonian Armed Forces during the VANGUARD 2026 exercise at Lithuania's Rūdininkai military training area. The vertical-takeoff system combines long-range strike capability with precision targeting. The exercise brought together 15 defence companies from seven countries to evaluate emerging technologies under realistic operational conditions. Lithuanian Minister of National Defence Robert Kaunas emphasised the importance of testing advanced systems capable of meeting the country's defence requirements and reinforcing NATO's eastern flank. Mach Industries CEO Ethan Thornton said the company develops systems based on insights from Russia's war against Ukraine. The demonstration results were later presented at a networking event hosted by the US Embassy in Lithuania, attended by defence representatives from multiple countries. The California-based company manufactures advanced unmanned systems and supporting industrial capacity.
