The US Navy will replace the touchscreen throttle and helm controls currently installed in its destroyers with mechanical ones starting in 2020, says USNI News. 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.” That setting meant that any crew member at another station could take over steering operations, and when the crew tried to regain control of the ship from multiple stations, control “shifted from the lee helm, to aft steering, to the helm, and back to aft steering.”

The NTSB report calls out the configuration of the bridge’s systems, pointing out that the decision to transfer controls while in the strait helped lead to the accident, and that the procedures for transferring the controls from one station to another were complicated, further contributing to the confusion. Specifically, the board points to the touchscreens on the bridge, noting that mechanical throttles are generally preferred because “they provide both immediate and tactile feedback to the operator.” The report notes that had mechanical controls been present, the helmsmen would have likely been alerted that there was an issue early on, and recommends that the Navy better adhere to better design standards.

[...] Touchscreens weren’t the only issue in the collision: the report calls out that several crew members on the bridge at the time weren’t familiar with the systems that they were overseeing and were inexperienced in their roles, and that many were fatigued, with an average of 4.9 hours of sleep between the 14 crew members present. The report recommended that the Navy conduct better training for the bridge systems, update the controls and associated documentation, and ensure that Navy personnel aren’t tired when they’re on the job.

    but but ... you need MORE buttons to replace one touchscreen (maybe)?

      If you need that many more buttons, you probably need to re-think what you are trying to do with the system in the first place, especially on a critical system.

      The bigger issue is too often requirements are along the line of "we want a fancy gadget, but we don't know what we want to do with it". Which means everything has to be software oriented. So controls wind up being generic mouse/keyboard/touch/whatever input.

        Tell this to jet liner manufacturer, the bloody bastards clearly didn't get to the wisdom of replacing all those buttons and throttles and whatnot with a single scroll wheel [theonion.com] (grin).

        Good from a marketing angle but it would need to have a shorter name to be called internally to the military. Any more than four words is pushing it. Like I could totally see "human-septic interface toggle" as the name for a military toilet flush lever. Short, technically accurate, and bloody stupid are the three characteristics you're going for in naming. Bonus points for short, letter/number combo model names, like the "OPENER, CAN, HAND, FOLDING, TYPE I", which is also known as the P38 can opener [wikipedia.org].

        Side note, that last is one sweet piece of equipment. It's smaller than your thumb, folds flat, can fit on a keychain, and can open most any can in ten seconds or less in experienced hands.

          This is the thing that most people who make fun of, "lol, a $5000 hammer" don't understand. Military stuff has weird requirements, being meant to be used in extreme circumstances, sometimes with literally life-and-death consequences. Sure having an extra 3 ounces doesn't sound like a big deal, and if it breaks just get a new one... until you are carrying it all day every day, and if it breaks from being run over by a truck and there is literally no replacement within 50 miles.

          I'd rather have a $5000 hammer guaranteed (and tested) to never produce a spark if I need to work around jet fuel. Sure that $5 one I can get from my local Home Depot might work 99.9% of the time, but would you want to use it?

            Odds are good the military is paying $50 for the hammer, and $4950 for the spy satellite.

          Hah! We even got that P38 in Sweden! The short lever action made it a bit of a pain on the more solid cans, but overall it's a very elegant tool. Damn near unbreakable too.

            P51 is larger and stronger, with two crimped-in “backbone” stiffeners instead of one. Much easier to use without breaking your fingers on heavy or large cans. Highly recommended over the original P38 can opener.
