What's supposedly the largest deep-sea remote-controlled robot ever built was rolled out this week: the SMD Ultra Trencher 1 (UT1), a 50 ton, £10m ($19.8m) ROV the size of a small domicile (25.5 x 25.5 x 18.3 feet). Capable of sucking up two megawatts of power while using its "jet swords" trench deep sea pipelines up to a meter wide and 2.5 meters deep into the sea floor (while operating at a depth of up to 1500m), the UT1 is clearly just in time. We hear the CIA errant anchors are due to snip another three or four deep-sea internet backbone cables, so the UT1's got its work cut out for it.
