The Royal Navy ordered its first unmanned submarine to Marlin Submarines (MSubs). The company has two years to produce Cetus. The submarine will move stealthily and monitor hostile activity by listening for ships or submarines.


The £15.4m Cetus will be the largest and most complex unmanned submersible operated by European navies. The Anti-Submarine Warfare Spearhead programme funds the project.

The submarine will be 12 metres long and 2.2 metres in diameter. The submersible will be unarmed and can dive deeper than any vessel in the current submarine fleet. The battery-powered craft will have 1000 miles range.

Cetus will work side-by-side with traditional crewed submarines.
