The US Navy Will Replace Its Touchscreen Controls With Mechanical Ones On Its Destroyers

The US Navy will replace the touchscreen throttle and helm controls currently installed in its destroyers with mechanical ones starting in 2020. From a report: The move comes after the National Transportation Safety Board released an accident report from a 2017 collision, which cites the design of the ship's controls as a factor in the accident. On August 21st, 2017, the USS John S. McCain collided with the Alnic MC, a Liberian oil tanker, off the coast of Singapore. The report provides a detailed overview of the actions that led to the collision: when crew members tried to split throttle and steering control between consoles, they lost control of the ship, putting it into the path of the tanker. The crash killed 10 sailors and injured 48 aboard the McCain. The report says that while fatigue and lack of training played a role in the accident, the design of the ship's control console were also contributing factors. Located in the middle of the McCain's bridge, the Ship's Control Console (SCC) features a pair of touch-screens on both the Helm and Lee Helm stations, through which the crew could steer and propel the ship. Investigators found that the crew had placed it in "backup manual mode," which removed computer-assisted help, because it allowed for "more direct form of communication between steering and the SSC."
