Submarine collision...odds?
A couple of years ago one of our nuclear submarines had a collision with its French opposite number in the Atlantic. We were assured at the time this was simply an unfortunate coincidence. Now I'm not into conspiracy theories. On the contrary since, mostly, honest cock-up beats conspiracy every time. But, really, what are the odds of a coming together, at the same depth, in hundreds of thousands of square miles of ocean?
Of course anyone who actually knows isn't likely to be posting here but as usual we can settle for the usual lightly-informed speculation...before I pop out for a beer with Elvis!

most likely they were hundreds of miles apart from one or the other and picked up a contact on sonar, classified it as a submarine and went to investigate (most likely using it as a training exercise). the ensuing drama would have involved both subs trying to stay hidden while keeping the other contact under surveillance. so know we are talking of subs only hundreds of meters apart that are both changing depth and headings continuously, and it is not that hard to see why they collided. it's not the first time either. it has happened a few times before. during the Cold War a US and Russian sub collided doing just what I described above. I think the conning tower on the Russian sub was almost torn off from tht collision.
I don't own this space under my name. I should have leased it while I still could
highflyer, hard to beat that description.
All I might add is that each probably had a discrete patrol area free from 'friendly' submarines.
Equally submariners may sneak out of their patrol area for reasons you describe.
We once dinged a 'blue' sub who was 90 miles outside his designated patrol area and thus a fair play 'orange' target.

The boats in question would absolutely not have behaved as described above - although some other types may well have.
Probability is another term for "odds" and what people tend to forget about probability is that although an event may have a very low probability, that does not preclude the event from occurring.

Highflyer, as I recall both of the submarines were strategic missile submarines, I always thought that their job was to keep out of the way of everything else to give themselves time and space to launch on order. Yes in the days of the Cold War there were collisions between NATO attack submarines and Russians, a very different set of circumstances.
The fact that they did collide in my view says either that the passive sonar that is meant to be the ears of the sub was not as good as it was thought to be or that both subs had better sound deadening etc than was normally expected.
I have a feeling that most Naval commanders who's vessels hit something normally get relieved of their command for risking their command, I never heard of anything happening?
The collision was reported to have been with a container that had been washed off a cargo boat to begin with until it became apparent that two submarines one French and one British had been damaged on the same day.

Seems most unlikely to me since, certainly in the normal course, the primary aim of submarines on deterrent patrol is surely to remain undetected, and not to go looking for trouble. VANGUARD was on such a patrol, whilst LE TRIOMPHANT was on passage.
Maybe if they put windows in the front of them then the sub drivers could see where they are going
Curiously enough, a well known submarine cartoon shows such a window, albeit in the side of submarine, marked "In case of fire break glass"!

IIRC, the USS Seaview had lovely large windows at the bow...

When this happened in 2009, the French were not fully integrated into the NATO command structure so didnt de-conflict their submarine movements. Also if Vanguard was on station she would have been doing her best to hide using any hydrographic anomolies such as ocean fronts that she could find. In some circumstances this can very much reduce sonar detection range. The French SSBN although in transit would have been looking for the same anomolies .... two semi blind submarines in the same bit of water ... BANG.

So, how do you get two missile boats, which normally try to stay away from everyone and everything, to bump into each other?
Well, try sending some assets to hunt for them - couple of attack boats, a few good MPA assets: its amazing how an attack trace and a couple of strings of sonobouys can cause confusion and herd normally solitary species into a confined space!

I wonder what their depth was in relation to the bathythermal conditions.
They may both have been traveling at the same depth that made sonar detection harder - sort of drastically reduces the odds of a collision if in one plane as opposed to 3D.
Perhaps (in peacetime at least) such submarines should adapt a separation scheme like aircraft - east at odd or even levels and vice versa for west, whatever suits.

Or even sail on the surface
"A Royal Navy officer who was skippering a racing yacht that hit an oil tanker in the Solent has been found guilty of contravening maritime regulations."
"Mr Wilson, who was a serving Royal Navy officer at the time but is now a lieutenant in the reserves, had seen the tanker from five miles (8km) away, Southampton Crown Court heard."

Its not that uncommon. Below is a link to a book that many fought to ban several years ago. Whilst it talks mainly about the USN it tells severall stories of "Allied" mishaps !
"Among the more remarkable stories detailed here are the Navy's successful attempts to locate a lost Soviet nuclear sub (which the CIA later attempted - embarrassingly unsuccessfully - to salvage from the bottom of the ocean), the mysterious loss of the US sub Scorpion (along with new information that would seem to finally explain the cause of the tragedy), and the collision of an American sub with one of its Soviet counterparts (just one of a surprising number of such collisions)"
