We’ve written about it before, but DARPA has finally confirmed the christening of its brand new autonomous submarine-hunting ship, agency directory Arati Prabhakar revealed. The Anti-Submarine Warfare Continuous Trail Unmanned Vessel (ACTUV) weighs 140 tons and is over 40 metres long.
The ACTUV is completely autonomous, and will be aided by sonar buoys that the US Navy will soon deploy. These will help the ship get its bearings to begin with, but it will take over shortly after and will use sonar to detect diesel electric submarines. Unmanned, the ACTUV can follow these submarines for months with no need to dock or resupply. It can also be used for reconnaissance missions, as well as deliver supplies to other vessels and counter undersea mines.
The ACTUV will be unveiled in Portland, Oregon. DARPA will then begin an 18-month demonstration of its long-range capabilities.
According to DARPA, the ACTUV will solve one of the major issues plaguing modern navies: budgetary shortcomings. Conventional ships take years to develop, and are incredibly costly to both build and operate. They require large contingents of sailors and constant resupplies.
The idea behind the ACTUV is that it and similar autonomous ships will reduce the strain on navies while allowing them to perform increasingly complex missions, or simply bolster the abilities of navies and free up limited human resources for those missions where human intervention is still required.
The current ACTUV design is a trimaran that is designed to test new sensors and advanced autonomous and propulsion systems, the latter are designed to outrun the fastest of diesel electric submarines.
