Lucky LaRue: Gotta hate it for that sub commander..


An attack submarine commander whose passive sonar is so poorly manned that it doesn't detect an undoubtedly very loud trawler/merchant driving right over it should be beached. That's like a US AFB that hosts a B-2 bomber wing and a couple squadrons of F-22s not noticing the Russian IL-76 until it's making a low pass down the runway.

Damage to the submarine was limited to one of its two periscopes while the vessel's nuclear reactor "remains in a safe condition"

So ... somebody out in the world thinks that a nuclear sub that bumps its periscope would affect the nuclear reactor that it needed to be clarified.

You shouldn't touch the ordnance at all.
But more specifically, you should never pull this hand-operating lever to the rear.
Do not push a clip of ammunition down into the feed rollers here.
You never restore this lever to firing position. Do not make sure that this cover is completely closed.
Never depress operator's foot triggers here, here and at the rear here.

I've actually been on a submarine when it collided with another vessel on approach to PD. I was not on watch, ironically because the OOD that did crash requested to swap the watch with me so that he wouldn't have to go to a long, boring ops briefing. The ops briefing itself was found to be a contributing factor, in fact.

Radioactive Ass and others have hit a number of good points. The PG is a pain in the ass to navigate because there just isn't that much good water (i.e. deep) that isn't also part of the shipping lanes or popular with fishing and dhow fleets. I'm not saying that cursed boat (this makes four for JAX) did nothing wrong; there aren't enough details. It could have been a merchant ship with a monster bow null (quiet spot when they're pointed at you), there could have been 30 contacts and they forgot to look at S/NR and multiple D/Es for additional range estimates, or perhaps it was a sailing vessel or DIW and not making any noise. I don't think it was a wooden vessel, though, because the #2 scope on a 688 will cut right through the outer hull of a 90kT LNG tanker, unless the scope just bumped the vessel aside because it was so light.

While I'll never get to see the collision report, unfortunately because I'm no longer in that area of the Navy, I'm sure they didn't use all the tools at their disposal unless JAX doesn't have the retro-fits that other non-i-boat 88s have gotten. The sub fleet trains like crazy on safe approaches to PD; every time there's a collision like Hartford getting run over by New Orleans, Newport News getting sucked up by that supertanker, or, long ago Oklahoma City bonking into a LNG tanker the whole fleet goes into "pound their brains" mode for all wardrooms, sonar shacks, and fire control parties.

I would be shocked if the CO keeps his job. Hell, I might know the guy.

1. The thermocline frustrates sonar, particularly passive mode.
2. They probably heard the ship and were using the periscope to pinpoint it's position.


Or it was a sailing vessel, or perhaps a motor vessel that was stopped, but when it got hit subsequently started up and moved off (perhaps thinking they drifted into an uncharted rock).

If the captain did everything right, and the crew did everything right, it could be written up as "unavoidable", and they captain won't suffer any consequences. So long as he didn't piss anyone off previously, that is.

I don't see in the artice where it states that the vessel was a trawler or a merchantman. You know what there are a lot of in the gulf?

BostonEMT: SO.... is there a radar "blind spot" directly above the sub?

/At least they didn't hit a boat full of school kids this time.


No radar under water.
They either can make an active search (pinging, which everyone can hear) or a passive one (which only hears things making noise).
It was just their bad luck a boat was drifting overhead.

The Persian Gulf is really to shallow and constricted for our large nuke subs. We some smaller diesel/AIP subs for operations in waters like these.

Unfortunately our ability to build such subs is about zero thanks to Admiral Rickover so we would have to pruchase some foreign designs.

I'm pretty sure striking another boat is a career ender. There's certain procedure for surfacing a sub and it would involve easily detecting a loud arse surface vessel within collision distance. Unless it's doing an emergecy ballast blow in a real emergency situation some people are going to get canned or lose rank because of this.

Yes, it needs to be explained.

The USS Jacksonville, a Los Angeles-class sub, "struck a vessel while operating in the Persian Gulf" at about 5:00 am local time (0200 GMT), the statement said.

"Jacksonville then surfaced from periscope depth to ascertain if there was any damage to the unidentified vessel," it said.


If I was a captain of some trawler in the Gulf and saw a Los Angeles-class attack sub surface next to me I'd probably just soil myself.

And hard to imagine a Los Angeles class periscope being damaged by another moving ship without repairs costing $10m or so. "Major damage" probably starts at around $100m.


Yeah, it will cost a lot of dough. Anything on a sub costs a shiatload to fix. It is sort of like how everything in an airport is 6x more expensive.

/my dad occasionally fixes periscopes on site. It will be interesting to see if I get an email saying "off to Dubai"

Maybe I'm an idiot, but I'd think protocol in that situation would be to put your periscope back in your pocket and cruise away whistling.
