Rheinmetall Kraken K3 Scout USV Enters Series Production at Blohm+Voss; ~200 / Year Scalable to 1,000
Hamburg, 20 April 2026
Key points
- Rheinmetall on 20 April launched series production of the Kraken K3 Scout unmanned surface vessel at Blohm+Voss in Hamburg; the JV with UK firm Kraken Technology Group is renamed Rheinmetall Kraken GmbH
- Initial production capacity: approximately 200 units per year, scalable up to 1,000 units annually depending on order volume
- Platform: 8.4 m hull, up to 55 knots, 2,500 kg maximum displacement, 600 kg payload; configurable for surveillance, critical-infrastructure protection or as a weapons carrier; first NATO orders already placed
Rheinmetall on 20 April launched series production of the Kraken K3 Scout unmanned surface vessel at Blohm+Voss in Hamburg, with the joint venture between Rheinmetall Naval Systems and the UK firm Kraken Technology Group renamed Rheinmetall Kraken GmbH — initial cadence approximately 200 units per year, scalable up to 1,000 units annually depending on order volume.
The K3 Scout platform is an 8.4-metre hull capable of up to 55 knots with a maximum displacement of 2,500 kilograms and a payload capacity of 600 kilograms. Configurations cover maritime surveillance, protection of critical infrastructure, and use as a weapons carrier in military operations. First NATO orders are already placed; further export traction is expected through the Hamburg shipyard's distribution network.
The line opens at Blohm+Voss, which Rheinmetall acquired through the March 2026 takeover of Naval Vessels Lürssen. Blohm+Voss now becomes Germany's principal test and series-production hub for unmanned maritime systems, sitting alongside the F126 frigate programme management contest Rheinmetall is pursuing in parallel through Rheinmetall Naval Systems.
Two hundred units a year is a production floor, not a ceiling. At 1,000 units, Blohm+Voss would produce more unmanned surface vessels annually than several European navies field manned combatants. The binding constraint is not throughput but order commitment — the line can scale faster than allied procurement cycles can generate demand signals — and the test variable through 2027 is whether NATO maritime users beyond Germany move from evaluation to framework-procurement scale. The trajectory was first surfaced in Signal No. 43.
