The planned deal was announced on Saturday by Polish Deputy Prime Minister and Defence Minister Władysław Kosiniak-Kamysz, who described it as part of efforts to strengthen the country's defence industry.
Kosiniak-Kamysz said the agreement would help establish a production facility in Poland for missiles used by the HOMAR-K rocket system.
The HOMAR-K is the Polish version of South Korea's K239 Chunmoo multiple-launch rocket system and is a cornerstone of Poland's artillery modernisation programme.
The launchers are mounted on Polish-made Jelcz trucks.
The system is comparable to the US-made HIMARS platforms that have been used effectively by Ukrainian forces against Russia.
Like HIMARS, the HOMAR-K can fire a range of munitions, including ballistic missiles capable of striking targets up to 300 kilometres away, officials said.
WB Group is one of Poland’s largest privately owned defence contractors. It supplies communications and combat management systems for the Polish army, including Krab self-propelled howitzers and Rak wheeled mortars.
The company also provides communications equipment for Poland's land forces, installed on Rosomak armoured vehicles, as well as unmanned systems such as the FlyEye reconnaissance drone and Warmate loitering munitions, according to state news agency PAP.
Hanwha Aerospace has supplied military equipment to Poland for several years.
The South Korean firm produces the K9 self-propelled howitzer, hundreds of which have been ordered by the Polish military, as well as the K239 rocket system.
