Midnight on a Navy Destroyer: People involved in preventing collisions
Posted on 8/20/17 at 8:59 pm
Posted on 8/20/17 at 8:59 pm
Bridge team:
-Helmsmen: usually 18-22yrs old, E1-E3. Makes course and speed changes as ordered by the conning officer
-Boatswains mate: in charge of announcements and oversees helmsman. Usually E3-E5, 21-25 years old.
-Quartermaster: in charge of charts and geographical obstacles. Qualified to do a movement board (calculates closest point of approach) using a surface watch radar station on bridge
-Conning officer: younger officer, 22-25 yrs old, maybe 01-O2. In charge of ships movement/course.
-Officer of the Deck: officer in charge of the ship and the captains orders. Oversees Conning officer. Usually 24-30, O2-O3.
CIC team (Combat Information Center)
- surface watch team: 3 OSs (operation specialists), 2 rotate between sitting on the radar tracking all contacts and standing by to preform manual moboards to determine CPAs (closest point of approach). Usually E2-E3, 18-22 yrs old. 3rd is a senior OS overseeing the other 2, usually E5-E6, 25-30 years old.
- Surface warfare coordinator: sits at radar next to surface watch team. Uses cameras to identify all contacts marked by surface watch team, in communication with people on watch at gun stations. Usually E6-E7, 30-40 years old.
How they work together:
Every ship that shows up on radar usually shows up 12-15 miles out, it is immediately marked by surface watch team and auto tracked by radar. When contact is initially identified it is reported to bridge team including course, speed, and closest point of approach. Bridge team acknowledges. CPAs are auto tracked by radar and if a future CPA projects within 2000 yds a manual moboard is performed and results are again communicated with the bridge team.
Basically every ship on the horizon is tracked, identified, and the bridge and CIC are aware of it along with aware of all changes. Reasons for collisions involve decisions of these watchstanders.
This is all based on personal experience not research so if duties or ages are not official or do not match others experience feel free to comment. Just trying to give anyone interested an idea of how things work on the ship.

That's exactly how it still works and those ages are pretty spot on. I don't understand how it happened, there are so many point of failures to occur to make this possible.

Unreal that this has happened twice within, what, 6 months?

Interesting information. Thank you.
If cars have anti-collision technology, why don't ships? Seems like an automated early collision warning system might be useful.

I don't know. Usually stuff like this results from massive breakdowns in unit cohesion/discipline.
Posted on 8/20/17 at 9:05 pm to JuiceTerry
Isn't this the 4th or 5th time this year?
Posted on 8/20/17 at 9:06 pm to Lsuchs
Maybe instead of self driving cars we should let computers drive the ships.

And when the machine breaks down, weeeee break down

I can see the first as aberration but this second one is giving me a great deal of pause. Something is seriously wrong. Whether the proper training or displine hasn't been implemented or a lack of vessels causing overworked crews, it needs to found and solved.

3rd time this year. All 3 ships involved have been from the 7th fleet stationed in Japan.

It just makes me wonder what they would do if these were hostile vessels
Posted on 8/20/17 at 9:10 pm to Devil_doge
Something in the water?

Someone on Twitter threw out the possibility of someone or some entity hacking the destroyer's navigation systems. This is way too coincidental...

It is unsettling.

Only thing I can think of is sometimes close approaches are required and intentional, the system taking over could lead to problems. I guess it's something you could turn on and off though
Also usually a last minute course change is made anyway when they realize danger, a computer wouldn't be able to communicate with another random vessel and both ships could turn into rather than away from each other. Even though that is likely what happened here anyway

If y'all want to get technical, this is the 4th major incident involving a US Navy ship this year.
The fourth incident also involved a ship from the 7th fleet that ran aground while trying to anchor in Tokyo Bay.

I'm not saying it's impossible...but this is highly, HIGHLY unlikely. Even for a Russian or Chinese APT.

I didn't mean an anti-collision system that would take control of the ship. I was thinking more along the lines of what commercial aircraft have in ground and other aircraft proximity warning technology.

Only thing I find strange about hacking is that the navigation system is GPS, and even if hacked wouldn't affect the local radar which is what is used to avoid collisions and track contacts on the horizon
Radar goes straight to the console and is not part of a computer network

Not only that, it's not like their network is connected back to shore via Comcast.
Ockhams's Razor here to be honest. The simplest answer is a breakdown in the chain of command/discipline of the ship.
The fact it has happened to multiple ships in a short period of time points to larger issues within the Navy, or at least 7th Fleet.
