Ukraine's GUR claims Polyus breach exposes Chinese optics in Iskander and Tianjin laser gyroscopes

Published 8 July 2026

Ukraine’s military intelligence directorate (GUR) claims to have exfiltrated dozens of gigabytes of classified files from NII Polyus, a Rostec institute specialising in laser technology, inertial systems, and quantum electronics. The material reportedly covers advanced defence-industry projects, missile and UAV modernisation programmes, and documentation of ongoing foreign-component sourcing. Two dependencies are specifically named: Chinese-manufactured optical parts embedded in the navigation and targeting systems of Iskander operational-tactical missiles, and laser gyroscopes sourced from the Tianjin Navigation Institute used in missile stabilisation systems. GUR characterises the haul as evidence of structural and growing Russian dependence on Chinese precision optics across guided-weapons programmes.
