DIU: UMPKs Contain Electronic Components from USA and Switzerland, and Some Manufacturers Are Not Yet Subject to Sanctions

The Defence Intelligence of Ukraine, as part of the War & Sanctions project, has published an investigation into the production of Russian UMPK (Universal Planning and Correction Module) modules.

The website features an interactive 3D model of the device, a detailed component database, and information about 31 companies in the aggressor state involved in this process.

Thanks to these devices, the enemy converts conventional unguided high-explosive bombs, such as FAB-250 or FAB-500, into guided munitions — so-called KABs, which are capable of hitting targets at long ranges.

Design and foreign manufacturers

The design of a typical module consists of a power frame, nose fairing, folding wings, elevons, and stabilizers. This entire mechanism is securely attached to the air bomb body using special steel clamps.

Guidance accuracy is ensured by the integrated SMART control system, which uses a Swiss signal relay from Axicom (TE Connectivity), a Chinese inertial module from MT Microsystems, a DC converter from XLSEMI, and an American transceiver from Sipex Corporation. The control system works in conjunction with a platform-free inertial navigation system and a noise-protected Kometa satellite antenna, which can have 4 to 8 elements.

In 2024, the enemy began to use FAB-500T aerial bombs equipped with UMPK-PD extended range modules. These devices have a significantly larger wing area and an extended power frame. The upgraded UMPK-PD modules are equipped with a 12-element Kometa-M12 antenna, which uses a Swiss GNSS module from U-blox, an American programmable gate array from Altera Corporation (Intel), and a digital-to-analog converter from Analog Devices.

In addition, the antenna uses an American DC converter from Linear Technology Corporation (Analog Devices).

Russian companies not subject to sanctions

The main developer and contractor for the state order for these modules is Tactical Missiles Corporation. This structure coordinates the work of dozens of factories that supply parts ranging from microchips to aluminum profiles for wings.

Six companies from the published list are still not subject to international sanctions. This allows the aggressor to freely purchase foreign components and equipment necessary to maintain production rates. The list of manufacturing countries includes Switzerland, the United States, and China.

Among these companies is JSC NPO Kurganpribor, which performs the final assembly of the UMPK-250 and UMPK-500 modules. The absence of sanctions pressure on this company facilitates the enemy’s access to Western machine tools and dual-use technologies.

Another critically important facility is ZAT Gefest and T. It develops and installs specialized SVP-24 “Gefest” computing subsystems on the main aircraft carriers of guided aerial bombs, in particular on Su-24M bombers and Su-34 and Su-35S fighters.

This list also includes Arzamas Foundry and Mechanical Plant Start LLC (aluminum and brass parts for SMART control units), PSB Technologies LLC (printed circuit boards and modules for Kometa-M antennas), Pantes LLC (electronic components and base modules for navigation systems), and Rikor Electronics LLC (power supply units and specialized circuit boards).
