Visão geral
Australian low-cost large uncrewed undersea vehicle with a 2,000 km range, built for mass production and exported to the United States.
Speartooth is a large uncrewed underwater vehicle from Brisbane-based C2 Robotics, designed around a 'small, smart, many' philosophy of affordable vehicles that can be built in volume. The composite-hulled vehicle is about 8 m long and 1 m wide in its base configuration and can be stretched to roughly 12 m with additional payload sections. It dives to about 2,000 m and has a published range of about 2,000 km on lithium-ion batteries. Two payload-agnostic bays accept ISR sensors, seabed payloads, or strike effectors, while a communications sail, inertial navigation, and collision-avoidance sensors support long autonomous transits. Speartooth emerged from Royal Australian Navy experimentation in 2022, and in May 2026 C2 Robotics commissioned the first unit exported to the United States.
