Ukraine’s Defence Intelligence (DIU) has identified 37 foreign-made electronic components used in Russia’s Kometa anti-jamming navigation modules, along with 28 companies involved in their production and supply chains.
The findings, published on the War&Sanctions portal, also identify 13 pieces of foreign technological equipment used to manufacture the systems.
Kometa modules are widely installed in Russian missiles, attack drones and guided aerial bombs to protect satellite navigation signals from electronic warfare interference.
The systems use Controlled Reception Pattern Antenna (CRPA) technology, which enables antennas to distinguish satellite signals from electronic interference by adjusting their reception patterns and processing incoming signals.
A standard Kometa module consists of an antenna array and a signal-processing unit built around Altera Cyclone field-programmable gate arrays (FPGAs), developed by a subsidiary of US technology company Intel.
According to Ukrainian intelligence, Russia is already deploying Kometa modules equipped with 16 antenna elements on a large scale and is preparing serial production of 20-element versions. Ukrainian intelligence has also identified a 32-element CRPA system manufactured through Chinese-Russian cooperation in Alabuga.
The principal developer and manufacturer is Russia’s VNIIR-Progress, part of the ABS Electro group, which Ukrainian intelligence links to sanctioned Serbian politician Nenad Popović.
VNIIR-Progress holds patents covering key technologies used in Kometa modules. Another group company, VNIIR, handles component procurement through Chinese electronics distributors and Russian intermediaries.
Ukrainian intelligence reports that Russian defence industry orders for Kometa modules have already substantially exceeded 100,000 units in 2026, covering various configurations.
To meet demand, VNIIR-Progress uses its own facilities, other ABS Electro companies and external manufacturers, including Pantes, Aviv, PSB Technologies, Erikon and Vector Group.
The newly disclosed component list includes products from nearly 20 manufacturers based in the United States, China, Switzerland, Japan and Taiwan.
Among the most critical components are Altera Cyclone programmable logic devices, analogue-to-digital and digital-to-analogue converters, and radio-frequency chips produced by US manufacturer Analog Devices and its Linear Technology brand.
According to DIU, VNIIR-Progress is actively seeking alternative suppliers and replacements for Altera and Analog Devices products because sanctions and tighter export controls have disrupted access to these technologies.
The agency argues that these procurement difficulties demonstrate the impact of international restrictions on Russia’s defence industry and the importance of further tightening controls on sensitive electronics.
The full lists of components, companies and manufacturing equipment have been published on Ukraine’s War&Sanctions portal.
