Ukrainian defence company Vyrii Industries has unveiled the lean flow model it has implemented in its factories to scale up and optimise drone assembly processes. The presentation took place at DOU Day 2026, a Ukrainian tech and defence industry conference.

Quote from Demydenko: "Previously, it would take one person a whole day to assemble 4-6 drones, and we needed to optimise that somehow. Gradually we started breaking the process up into stages across departments, so that each department was performing one step. Now we've moved to a flow assembly system, where all operations are divided up within a line of nine people. The first assembles the frame, the second mounts the motors, the third fixes the wiring, and so on. The result is that every three minutes we get a fully assembled drone."
