► WB GROUP and Optix sign teaming agreement

28 September 2026 – WB GROUP and Bulgarian company Optix have signed a teaming agreement covering the transfer of technology for the FONET communications platform, the TOPAZ system and the COMP@N radios. Cooperation between the Polish and Bulgarian companies will support the development of local industrial capabilities, enhance security of supply and strengthen the technological capabilities of countries on NATO’s eastern flank.

WB GROUP and Bulgarian company Optix signed the teaming agreement at the Embassy of the Republic of Bulgaria in Warsaw. The document was signed by Piotr Wojciechowski, President of WB GROUP, and Petar Cholakov, Chairman of the Board of Directors of Optix, in the presence of Michaela Karadimova, Deputy Minister of Economy, Investment and Industry of the Republic of Bulgaria.

The agreement sets out the framework for WB GROUP and Optix to prepare a technology-transfer plan covering the production, integration and in-service support of FONET and TOPAZ systems, as well as COMP@N tactical radios, in Bulgaria for use with artillery systems.

The agreement was signed during the official visit of Bulgarian Prime Minister Rumen Radev to Poland. The Bulgarian delegation included, among others, Defence Minister Dimitar Stoyanov and Deputy Prime Minister and Minister of Economy, Investment and Industry Aleksandar Pulev. The visit was also accompanied by a delegation of representatives from the Bulgarian business community.

Under the agreement, Optix is expected to become the Bulgarian centre for the assembly, installation, configuration and after-sales support of systems offered by WB GROUP. The Bulgarian partner will receive the required technical documentation and equipment, as well as specialist training.

FONET is an advanced communications platform developed by WB GROUP for use in military vehicles. The system is in service with the armed forces of dozens of countries and is manufactured in Poland as well as under licence in several other countries, including the United States.

It is integrated with, among others, Krab and K9 self-propelled howitzers, M120K Rak self-propelled mortars, and Langusta and Homar-K rocket launchers. In addition to Poland, the interoperable TOPAZ command-and-control system is also used by customers in other countries, including NATO allies.
