Rheinmetall-Kraken joint venture building the K3 SCOUT uncrewed surface vessel in Hamburg
Last refreshed: 24 July 2026
Background
Rheinmetall Kraken GmbH is a joint venture between German defence group Rheinmetall and British uncrewed-surface-vessel maker Kraken Technology Group, running series production of the K3 SCOUT vessel at a Hamburg shipyard. The venture began life as NVL Kraken, formed around August 2025 with Naval Vessels Lürssen, part of the Lürssen Group, which then owned the Blohm+Voss yard. After Rheinmetall acquired Blohm+Voss in February 2026, the joint venture was rebranded Rheinmetall Kraken GmbH. Series production of the K3 SCOUT launched at the Hamburg site on 20 April 2026, with initial capacity of roughly 200 units a year, scalable towards 1,000 a year. The venture anchors Kraken's uncrewed-vessel manufacturing within Germany's naval-industrial base and sits alongside Rheinmetall's own investment in Kraken's $175m Series B round .
