Rheinmetall will present its Kraken K3 uncrewed surface vessel, a self-contained Millennium gun system and the new MASS Nova decoy launcher at Euronaval 2026. The German company’s offering spans autonomous platforms and shipboard weapons intended to support fleets combining crewed and uncrewed vessels.

Kraken K3 is already in series production at Rheinmetall’s Hamburg site and will be presented to a wider audience for the first time at the exhibition. The company also identified its newly developed GMF 140 guided-missile frigate as part of its approach to future naval requirements.

The Millennium configuration is designed to operate independently of a host ship’s onboard data infrastructure, providing an option for modernisation programmes. It combines an Oerlikon AMMR active electronically scanned array surveillance radar, fire-control radar, an electro-optical tracker and a compact command-and-weapon-control system.

The S-band radar supports short-range air defence, while the integrated mini combat management system combines sensor data in real time. Rheinmetall said the configuration allows an operator to control the full engagement chain against air and surface threats.

MASS Nova, making its debut at Euronaval, introduces a redesigned launcher with variable firing angles and capacity for 40+4 rounds of 81mm Omni-Trap decoy ammunition. It can fire more rapidly than the previous system, allowing a faster response to incoming threats, according to Rheinmetall.

The company will also display FV-014, a loitering munition designed to combine reconnaissance, target identification and precision engagement at operational ranges of up to 100 kilometres. Rheinmetall said its sensors, network connectivity and autonomy support operations against armoured and unarmoured targets, including under satellite-navigation interference.

Asteria multi-effect sea mines complete the announced exhibition portfolio. They can be deployed from surface vessels, transport aircraft and submarines, with a bidirectional acoustic link allowing remote control for missions around harbours, straits, port facilities and other critical areas.
