4iG SDT and CSG Expand Defense Partnership with Hirtenberger Stake Acquisition
Hungarian IT and defense group 4iG and Czech-based CSG are deepening their cooperation through a joint move into Austria’s defense industry. The partners have acquired a stake in Hirtenberger Defence Europe, marking a step toward broader regional industrial integration.
Hungarian company 4iG and Czech defense-industrial group Czechoslovak Group (CSG) are expanding their strategic cooperation through a joint investment in Hirtenberger Defence Europe.
According to the companies, the transaction involves the acquisition of a stake in the Austrian-based manufacturer, which specializes in mortar systems and ammunition. The move reflects a broader effort by both groups to strengthen their presence in the European defense market and enhance industrial capabilities within NATO-aligned supply chains.
The partnership builds on an existing alliance between 4iG’s defense subsidiary and CSG, aimed at developing joint projects and leveraging complementary portfolios. Officials indicated that the Hirtenberger investment is intended to support production capacity expansion and facilitate access to additional markets.
Hirtenberger Defence Europe operates as a long-established supplier of indirect fire systems, with products used by multiple armed forces. By integrating the company into a wider regional framework, the partners are seeking to reinforce supply resilience and reduce dependency on external providers.
The development comes amid increased defense spending across Europe and a growing emphasis on domestic and regional industrial capacity. Central and Eastern European companies have been pursuing consolidation and cross-border partnerships to position themselves within evolving NATO procurement structures.
While financial details of the transaction were not disclosed, the companies signaled that further joint initiatives may follow as part of a long-term cooperation strategy focused on defense manufacturing and technology integration.
