The contracting authority selected the offer following negotiations, and on June 23 this year awarded a contract worth 5,000,000 PLN gross to WB Electronics, part of WB Group, with completion scheduled by November 30, 2026. The contractor offered the following prices:
- one labor-hour of fault diagnosis at the user’s site:585.00 PLN net (719.55 PLN gross);
- one labor-hour of fault diagnosis at the contractor’s site: 585.00 PLN net (719.55 PLN gross);
- one labor-hour of repair at the user’s site: 585.00 PLN net (719.55 PLN gross);
- one labor-hour of repair at the contractor’s site: 585.00 PLN net (719.55 PLN gross);
- travel, per-kilometer rate: 1.15 PLN net (1.41 PLN gross);
- per diem cost: 780 PLN net (959.40 PLN gross).
The justification states that WB Electronics declared that it is the creator and sole owner of the copyright to both the mechanical and electronic design and the software related to the Fonet Onboard Internal Communications Equipment Suite, and that it holds a registered trademark for the Topaz Automated Fire Control Suite. It also declared that it has not made, and does not intend to make, the rights to the technical documentation available to other business entities.
Fonet
The Fonet digital vehicular communications platform is a suite of devices and software that creates a unified data-exchange base between vehicles on the battlefield. It was developed by WB Group and delivered to the Polish Armed Forces in more than 10,000 sets. It has been installed, among others, in Rosomak wheeled armored personnel carriers (KTO) of all versions, including M120K Rak 120-mm self-propelled mortars and command vehicles; AHS Krab and K9A1 Thunder 155-mm self-propelled howitzers, and in the future also K9PL howitzers; older wz. 1977 Dana and 2S1T Goździk howitzers; T-72M1R and PT-91 Twardy tanks; and the latest M1A2FEP/SEPv3 Abrams and K2GF Black Panther tanks, and in the future K2PL tanks (WB Group systems for new tanks).
WB Group has also developed a naval variant, Fonet-Navy.
One of its basic functions is to provide digital voice communications using available communications assets. The Fonet Digital Communications Platform is compatible with any radio available on the market. In addition, the system integrates a vehicle’s electronic equipment and controls wired and radio networks. Vehicles equipped with Fonet can operate within automated command or fire-control systems. The modular concept of the system makes it possible to select the appropriate configuration for each vehicle while ensuring full compatibility for voice communications and data exchange.
The Fonet system has been further developed through a range of software solutions that enable the execution of tasks required by the modern battlefield. Thanks to full support for IP-based solutions and the integration of all available communications assets, the system allows vehicles equipped with it to be incorporated into a wide-area IT network for data exchange and VoIP voice communications. A vehicle fitted with the Fonet system becomes an effective element of current and future command-and-control and battlefield management systems.
In 2018, the Fonet digital communications platform was used to build command vehicles based on the Rosomak 8×8 wheeled armored personnel carrier platform, intended for the headquarters of the Multinational Division North East in Elbląg. The ICT system based on Fonet-family devices is an example of a modern solution and provides, among other capabilities, full control as well as voice and data exchange in both unclassified and encrypted modes via Harris radios such as the AN/PRC-150C and AN/PRC-117G. The architecture of the ICT system meets the requirements for processing information classified as NATO SECRET. Each FONET system device was tested for resistance to cyber threats and underwent testing at the Military Counterintelligence Service laboratory. All devices received certification allowing them to operate in NATO SECRET-classified systems.
The Fonet digital communications platform has for many years been produced under license from WB Electronics by Harris Co., a global leader in the radio market and now L3Harris Technologies, as part of the FALCON III family under the RF-7800I designation. It is installed in thousands of vehicles and command systems worldwide.
Fonet is a solution that provides the communications backbone for a variety of battlefield management systems, including the Topaz Integrated Combat Management System.

Topaz
The origins of the Topaz system date back to the 1990s, when the Rocket Forces and Artillery (WRiA) received the modern Topaz Automated Fire Control Suite, based on the Fonet digital communications platform. It was a complete system used not only for fire control, but also to support tactical operations on the battlefield.
Technological advances and the changing conditions of the battlefield prompted the system’s continuous development by WB Group engineers. Integration with new types of reconnaissance and strike assets, such as unmanned systems and loitering munitions, made it possible to significantly expand the system’s functionality. Domestic and international experience from the operation of the Topaz Integrated Combat Management System, including combat experience from contemporary armed conflicts, led to the system being expanded with functions related to command, logistics support, loitering-munition strike control, and radar, electro-optical, and acoustic reconnaissance. Requirements for operation in a coalition environment enabled practical validation of the interoperable solutions and protocols of the Topaz Integrated Combat Management System, such as MIP, NFFI, NVG, and JCHAT, as well as visualization on digital map backgrounds compliant with Polish Armed Forces and NATO standards.
One of the basic features of the Topaz system is its modularity and scalability. Topaz can be easily configured for battlefield management at various tactical levels. Its catalog of integration packages covers all products offered by WB Group and key sensors from major global manufacturers, such as inertial navigation systems, battlefield radars, and electro-optical reconnaissance assets. Topaz modules enable the use of various radio communications systems from global manufacturers, including HF, VHF, UHF, and SATCOM, as well as wired and wireless broadband communications to support planning at higher command levels.
The Topaz system consists of the following modules:
- Topaz Tactics – providing BMS functionality, including digital map handling, visualization and exchange of tactical situation information, blue-force tracking (BFT), and interoperability in a coalition environment;
- Topaz Fires – a module for controlling various tube and rocket artillery assets;
- Topaz Recon – a reconnaissance module covering electro-optical systems, radars, UAVs, and other reconnaissance sensors;
- Topaz Strike – control of unmanned strike assets, such as Warmate unmanned combat vehicles;
- Topaz Logistics – management of supply processes, such as ammunition delivery, and service support.
The Topaz Integrated Combat Management System is a solution that enables effective use of current and future military assets. Continuous improvement and expansion of the system by a leading Polish supplier of communications and command systems ensures that the user maintains a lasting information advantage over the adversary. Today, the Topaz Integrated Combat Management System is a comprehensive and modular system solution that provides commanders at every command level with full control over the battlefield situation.
Previously, Topaz had been integrated with 122-mm 2S1 Goździk self-propelled howitzers, 155-mm wz. 1977 Dana wheeled howitzers, 155-mm Krab self-propelled howitzers, 120-mm M120 Rak self-propelled mortars, 122-mm WR-40 Langusta multiple rocket launchers, and 98-mm M-98 towed mortars. It was subsequently integrated with K9A1 Thunder howitzers and Homar-K multiple rocket launchers.
On July 7, 2023, the Armament Agency signed an implementing agreement with WB Group covering the modification of the Topaz system to the Topaz+ Automated Command-and-Control System for Effectors standard within joint fire support, together with the implementation of the ASCA (Artillery Systems Cooperation Activities) interface.
