About This Collision.

As RT reports the US Navy came to the conclusions re: USS Connecticut (SSN-22, Seawolf-class) with what amounts to the running ship (sub) into the ground in a classic navigation mishap.   

The US Navy has relieved the captain, executive officer and chief sonar technician of USS Connecticut, the nuclear-powered attack submarine that struck an undersea mountain in the South China Sea last month. Commander Cameron Aljilani, Lieutenant Commander Patrick Cashin and Master Chief Sonar Technician Cory Rodgers were relieved of command “due to loss of confidence,” the Navy said on Thursday.Vice Admiral Karl Thomas, commander of the 7th Fleet, has determined that “sound judgement, prudent decision-making and adherence to required procedures in navigation planning, watch team execution and risk management could have prevented the incident.”
In terms of disciplinary action it is totally expected, as Soviet/Russian Ships Manual (soon to be replaced with a new one) states--Commanding Officer is responsible for the ship and everything what happens there. I am sure the same approach exists in the US Navy. You broke the ship--you lose your command in most cases. There are some (rare) exceptions, of course, to this rule.

The Seawolf-class SSN-22 fast-attack submarine was in the South China Sea on October 2 when it struck an “object” and had to return to Guam for damage assessment. The object was later revealed to have been an “undersea mountain,” according to the US Naval Institute. Several members of the Connecticut’s crew were injured in the collision, though none of the injuries were life-threatening. The submarine’s nuclear reactor was not affected. The boat will remain in Guam until the damage assessment is completed, at which point it will sail to Bremerton, Washington shipyards for repairs, the Navy said.

Connecticut is a 22 years old sub (she was commissioned in 1998), which means that she has a state of the art navigational complex and Combat Informational Control System designed to provide a high level of situational awareness. Unless one doubts (I don't see much reasons to doubt it) that Connecticut indeed ran into the uncharted feature (seamount) as 7th Fleet press-release states, the fault inevitably lies with: 

1.  Naval Oceanographic Service, aka NAVOCEANO, which either didn't chart that seamount (why--is a separate story) or didn't issue an appropriate navigational warning about the area; 

2. Obviously, organization of the watch and tactical and navigational proficiency of the team responsible for safety of the ship (sub) underway. 

I do not know all the facts, but considering capabilities of modern navigational complexes (be that US or Russian, British, I assume too) to provide an extremely accurate dead-reckoning (its very high reliability) over very long periods of time, including active maneuvering at different speeds, it does come across, from what I know (which is nowhere near to all the facts), that navigational service onboard Connecticut was not the best-organized, to put it mildly. Plus, do not discount CO's decisions. But Connecticut is not the first US sub or ship which ran into the ground (seamount) in the last few years. There is an established fact of the US Navy effectively putting navigational training of the crews on the back-burner. This whole thing is on record. 

In other words, navigational problems in the US Navy are not new. Every serious navy in the world has its share of navigational mishaps, but the US Navy's problem with seamanship and navigational safety seems to persist. I know how one feels when having an advanced technology at own disposal (I know the feeling really well) but basic, time-tested skills of navigators and interaction of the watch officer with both CO and navigator are of crucial importance, especially when being underway submerged. And especially in the area where any mishap may lead to conflagration. The technology is only as good as people who operate it. Could the Connecticut affair be the case of the fatigue, as was one of the factors with USS Fitzgerald as NTSB concluded? Possible. Swedish Komsomolets, certainly was. I'll give you a hint--only experienced navigation officers should be next to navigation complex when submarine is underway submerged. Was this rule followed by Connecticut's CO? We may never know, but in the end--CO is always the guy who takes the fall.

What Can I Say.

The first rule, a golden one, of the watch (officer) and, in case of ships of such rank, combat informational center, is this: BE CONSTANTLY AWARE OF THE SITUATION AND ACT ACCORDINGLY. The rest, COLREGS, maneuvering boards, collision avoidance means and protocols, professional knowledge of maneuvering characteristics of own ship, navigation--all that comes after constant maintenance of situational awareness by all: electronic, optronic and other means at the disposal. But all this, becomes irrelevant when you are, well, let the press talk:
COPENHAGEN, Denmark — A Norwegian Navy frigate was rammed by a tanker while it was docked in a harbor on the country's west coast Thursday, the military said. The crew of 127 was evacuated amid fears the ship will sink. Eight people on the KNM Helge Instad were slightly injured when the accident occurred at 4 a.m. local time in Sture, north of Bergen, the Joint Rescue Coordination Center for southern Norway said. The military said the ship, which had recently taken part in the vast NATO drill Trident Juncture, is taking on water. Eirik Walle, with the rescue center, told Norwegian news agency NTB that the collision caused an opening in the frigate's hull and "it is taking in more water than they can pump out. There is no control over the leak and the stern is heavily in the sea."The Maltese-flagged tanker, Sola TS, was not damaged and its 23-man crew remained on board.


You can see the damage which immediately brings up the issue of: what were they thinking at the bridge of a tanker? Tankers are big, stupid and barely maneuverable. 



At least nobody died in this 5,300 tons of displacement against 120,000. You know, Geo Metro against 18-wheeler semi fully loaded. Here is this Sola TS. She is big.


We'll have to wait for more details coming out soon.    

UPDATE: In related (naval) news. 

Officials: Ronald Reagan LSD probe bigger than you think, 14 nuke sailors snagged

Holy shit!
