British unmanned surface vehicle (USV) builder Kraken unveiled the K7 Sabre at the Euronaval 2026 exhibition, held in Paris from 3-6 November. It is the largest vessel in the company's portfolio disclosed to date.
Kraken presented the K7 Sabre in a soft launch at Euronaval, displaying a model of the USV behind a full-scale K3 Scout that dominated its stand.
The K7 had previously been mentioned publicly in a 21 April press release detailing Kraken's co-operation with Anduril, which will build the K5 and K7 USVs at its US facilities. Kraken referred to the K7 again in written evidence submitted to the UK House of Lords Industry and Regulators Committee on 21 July.
Euronaval was the first occasion on which Kraken disclosed K7 specifications.

Kraken expects to deliver a prototype in early 2027, although the representative would not confirm whether delivery was expected in the first quarter.
The K7 is intended to meet what Kraken sees as an emerging role for USVs carrying standard-sized maritime containers. Its stated payload capacity is 24 tonnes, and it is 26.5 m long. It will be able to carry one 40 ft container or, as the model indicates, three closely packed 20 ft containers.
