People walking along the Thames by Tower Bridge one day in September 2016 might have been surprised to see a fair-sized battleship making its way up river, and ahead of it a futuristic looking speedboat chugging along performing manouevres. The speedboat can actually do over 60mph if opened up fully, and versions of it are operated by navies all around the world, including Iran’s. But this version is a little different. Called MAST (Maritime Autonomy Surface Testbed), it is the British Navy’s first experiment in autonomous boats.
