RSI Europe, a Lithuanian drone manufacturer in Vilnius, signed a memorandum of understanding with Ukraine's The Fourth Law at Eurosatory on 18 June 2026 to build drones in Lithuania under the Build with Ukraine framework1. The Fourth Law supplies the artificial-intelligence, computer-vision and manufacturing know-how; Ukrainian citizens are given priority for the production jobs. RSI is already delivering 9,500 Shpak FPV first-person-view drones to an undisclosed NATO buyer.
The deal advances a corridor that opened when Fire Point broke ground on a Danish plant and Kyiv announced ten EU export offices. Ukraine's Fire Point is scaling FP-1 output to more than 100 a day at Denmark's Skrydstrup airbase, set against the roughly 4 million drones Ukraine builds at home each year. The volume travelling abroad is small by that measure, which is not the point of the move.
What travels with the production matters more than the throughput. Design know-how and combat-iterated software, refined over three years against Russian drones, now flow into NATO states alongside the airframes. Kyiv's wartime export ban still blocks the hardware, so it sells the harder asset instead, while host states absorb the manufacturing and the political risk of weapons plants on their territory. The export ban has been converted into an industrial-transfer business: Lithuania for assembly, Denmark for propellant and airframes, with Ukraine retaining the intellectual property.
