German company Eurobotics displayed a section of its Speartooth large unmanned underwater vehicle (LUUV) with a new optronic mast and MBDA air-launched effectors (ALE) at the Euronaval 2026 exhibition, held in Paris from 3-6 November 2026.

Eurobotics proposed the configuration, which combines intelligence, surveillance, and reconnaissance (ISR) equipment and strike capability in the same 2.6 × 1.6 m payload bay, Markus Sellmer, Intec's head of naval systems, told Janes on 5 November 2026. Fellow German company Intec is a separate business within the wider Aegiron group, which also owns Eurobotics, and has its own strategic partnership with C2 Robotics focused on Speartooth.

The configuration shown at Euronaval differs from the one used during NATO's Bold Machina 2026 exercise. Janes reported on 16 September that Speartooth used two separate payload modules during an ISR mission at the Lisbon Naval Base in Alfeite, Portugal.

Navies are prioritising ISR and the protection of undersea infrastructure amid concern about increased Russian submarine activity in north-west European waters, which the UK Ministry of Defence has publicised. Eurobotics expects demand for persistent surveillance to be accompanied by interest in strike capability. “For us, it was a specific target market,” Sellmer said.

Strike capabilities are not new to UUVs. The Royal Australian Navy has used Anduril's Altius loitering munition from its Ghost Shark XLUUV, according to a 19 October government statement. For Speartooth, despite its ISR focus during the Bold Machina exercise, a Eurobotics representative discussed the future potential for deploying one-way effectors.
