RSI Europe

What RSI Europe does

RSI Europe (UAB RSI Europe) is a privately held Lithuanian defense technology company founded in April 2022 in direct response to Russia's full-scale invasion of Ukraine. Headquartered in Vilnius, the company designs and manufactures remote strike and electronic warfare-resistant systems for NATO member state armed forces and the Ukrainian Armed Forces. Its core products are the Shpak 10-inch FPV drone family (with fiber-optic control and terminal guidance variants), the RISE-1 remote initiation system for military engineering applications, the Drone Repeater Kit (DRK) for extended-range FPV operations, and NDAA-compliant electronic components (ESC and FCU). The company is also developing integration with ATAK and SitAware battle management systems and Picatinny-rail payload mounting to embed its hardware into allied C2 ecosystems.

The underlying technology platform centers on multi-band Frequency-Hopping Spread Spectrum control, fiber-optic control for total jamming immunity, AI-assisted terminal guidance for autonomous strike phases, and non-standard frequency modulation for the RISE-1 initiation system. RSI Europe operates a dual-track development model: a fast-iteration track for Ukrainian battlefield feedback and a slower NATO-certified track for allied procurement. The company has obtained AQAP 2110:2016 NATO quality certification (surveillance audit passed April 2026), ISO 9001:2015/14001:2015/45001:2018 certifications, and holds official supplier status with the NATO Support and Procurement Agency (NSPA), with NSN codes assigned across the product line and STANAG compliance.

RSI Europe generates revenue primarily through direct hardware sales (FPV drones, remote initiation systems, repeater kits, electronic components) to defense ministries, NATO procurement agencies, and via a distributor network in France, Greece, Latvia, Sweden, Belgium, and Israel. Secondary revenue comes from professional services: a five-module FPV loitering munition operator training course, FPV OPFOR simulation services for military exercises, and custom Military IoT integration and customization. Pricing is quote-based under multi-year contracts; in 2025 the company recorded EUR 15.5 million in revenue with more than 99% exported and expanded into 12 new NATO member state markets.
