Investigators from Slidstvo.Info analysed leaked documents from Alabuga plant, where Russian drones are manufactured and learned how much material is needed to make each drone.

The authors found that Russian companies purchase epoxy resin needed for production of drones from two German companies, R&G Faserverbundwerkstoffe and Goettle Advanced Products GmbH & Co.Kg.

Business & Human Rights Resource Centre invited both companies to respond. R&G Faserverbundwerkstoffe sent a response which can be found below.
