    Audition au Sénat É.-U., le commandant des forces de surface reconnait des éléments qui ont été soulevés très tôt :
    • horaires délirants, plus de 100 heures par semaine
    • aggravés par une organisation du quart perturbant les rythmes biologiques
    Il va jusqu’à envisager d’accroître la visibilité des navires de la flotte en laissant actif leur AIS !

    On the personnel readiness side, Commander of Naval Surface Forces Vice Adm. Tom Rowden recently mandated that ship crews move to a 24-hour circadian rhythm watchstanding rotation, to allow sailors to get regularly scheduled sleep that their bodies can adjust to, Richardson explained during the hearing. This schedule had been recommended previously and implemented on some ships, but now all surface ships will develop this type of schedule for at-sea operations. Richardson said the change has not yet been mandated for ships in port, but that in-port workload and watchstanding rotation is being studied now. Additionally, to combat the 100-plus hours a week sailors sometimes work – which contributes to lack of sleep – “we’re starting to respond to that by supplementing the crews,” he said.

    “There are measurable degradations in decision-making and in performance” when sailors do not get proper sleep, CNO noted.

    On the ship side, Richardson said that simple steps such as turning on warships’ automatic identification system (AIS), which shows the location of commercial and military ships in the water, would increase warships’ visibility in congested waterways and potentially prevent future mishaps. The material readiness of the forward-deployed surface ships will also become more of a priority, with problems involving ship control systems being given an increased priority for repairs going forward, Richardson added.

      CNO : U.S. Navy Ships Told to Turn #AIS Transmitting ’ON’ in High-Traffic Areas – gCaptain

      You may recall that following the Fitzgerald and McCain collisions, AIS animations of the incidents only included information for the merchant vessels, leaving the tracks of the warships a mystery in both cases. 

      When asked by committee member Senator Angus King of Maine about the technology available to Navy sailors and other ships to help with collision avoidance, Admiral Richardson responded that the Navy has taken action to turn the AIS systems on its vessels back on, particularly in high-traffic areas.

      The other question is about these ships that ran into us,” said Senator King, referring to the merchant vessels involved in the collisions. “Is there some technology that they couldn’t see us? Are we using a stealth technology?

      Sir, it wouldn’t surprise anybody that we design our warships to have a low radar cross-section, some even designed to be very low, so that degree of stealth makes us more effective from a war-fighting standpoint,” said Admiral Richardson. “But that also imposes a burden, if you will, on the crew of that ship to understand that they are low-observable, to understand that they might not be seen as something that is as large as a destroyer. It will have a radar cross-section of a ship that is much smaller.

      Or they are not in a conflict situation, that they emit some kind of signal,” said Senator King.

      Admiral Richardson continued:
      That’s been an immediate action. There is this Automatic Identification System, AIS. We had, I think, a distorted perception of operational security that we kept that system secure – off – on our warships. One of the immediate actions following these incidents is that, particularly in heavily trafficked areas, we’re just going to turn it on.
