The WB Group Agreement with Hanwha Aerospace: On 22 February 2023 at the Warsaw office of WB WB, WB Electronics S.A. and Hanwha Aerospace concluded an agreement on the integration of Polish information systems, field management and communication with Chunmoo rocket launcher modules.
The contract was signed by Piotr Wojciechowski, president of the WB Group and boy Jae-il, president of the confederate Korean company Hanwha Aerospace.
The agreement concerns digital integration vehicle communication platform FONET, TOPAZ combat management system and 2 radio communication systems (delivered by RADMOR, subsidiary of the WB Group) on 218 self-propelled rocket launchers ordered by the Armed Forces of Poland in November 2022.

The fresh rocket launchers to scope the Rocket Army and Artillery will be vehicles on the wheel chassis of Jelcz 8×8, on which the Chunmoo launcher modules developed by Hanwha Aerospace were built.
That's another 1 of those self-propelled cannons. K9 contract for the integration of command, communications and control of the WB GROUP battlefield signed with the South Korean arms group.
TOPAZ has been the primary strategy of combat management and exchange of tactical information for nearly a 4th of a century in the sub-units of rocket and Artillery and Land Forces. This is simply a modular set of BMS-class applications designed to give the commanders full control of the situation in the battlefield.

TOPAZ was introduced into all artillery sets of the Polish Army – from the 122 mm Haubic 2S1T Worźk track tracks, through the 152 mm Dan-T cannonhaubice, the WR-40 Langusta rocket launchers, to the Regina Divisional Fire Modules (with 155 mm Self-propelled Crab Cannoneers) and the Company Fire Modules Cancer (with 120 mm M120K self-propelled mortars).
TOPAZ defined the applicable standards in the Armed Forces of Poland. This solution is constantly developed, adapted to the needs of users, integrated with circular and caterpillar artillery and rocket systems in the Polish Army and the armed forces of another states.
South Korean company Hanwha Aerospace is 1 of the most crucial abroad partners of the WB Group. Signing the contract is simply a success of the leading Polish maker of advanced electronic and IT systems from Ożarow Mazowiecki and proof of trust in solutions from the Ministry of National Defence.
The contract is another confirmation of the ability of the WB Group to integrate solutions created by Polish engineers and designers with abroad military equipment. As a result, the Polish Army will have a coherent strategy of communication, field management and communication for rocket artillery divisions.
Chunmoo is simply a self-propelled rocket launcher, with ammunition loaded into the launcher module in transport containers. This importantly accelerates the replacement of a fire unit and allows the usage of rocket missiles of various calibers, including 239 mm guided and 600 mm tactical.
The set under the name K239 entered service in the armed forces of South Korea in 2015. Allows indirect fire to be conducted in all weather conditions.
