It could well be that the Russian submarine Krusk was sunk by U. S. subs. In the first place, this huge monsterous Russian nuclear sub, calld "Mongo" because of its huge size, was not on a training mission, it was on war patrol. It's mission was to take out U. S. carriers or other major U. S. naval targets if ordered to do so.
Every Russian sub of this type was always trailed by U.S. subs as a defensive measure, just as Russian subs trailed our boomers when they could.
In the world of underwater warfare it is universally understood that the opening of torpedo or missile doors was the signal to trailing subs that a tarpedo or missile was about to be launched.
If the Krusk opened its tarpedo tube doors or missle silo doors it was asking for trouble.
Wrong. It was on a several day "weapons exercise".
I suggest that you read "Cry from the deep", by Ramsey Flynn. The Kursk was a disaster waiting to happen.
The book gives some insight into the "short shrift" that the Russian submarine fleet was given in Russian military spending.
For instance, very few of the cranes used to load torpedos into the subs were functional. They had been built by the Ukrainians and Russia was reluctant to give the Ukrainians money to keep them maintained. In fact, while loading the Kursk, one of the torpedos was dropped onto the dock.
The HTP torpedos were a disaster. They leaked and were subsequently subject to "cooking off". The warehouses which kept the torpedos typically released the worst ones, to get them the hell out of the building.
It was one such HTP torpedo that eventually "cooked off" while in the tube, awaiting firing. The resulting fire set off another four or so non-HTP torpedos.
"Candygram for Mongo"? LOL!
Absolute non-sense. It was on exercise with other vessels including Peter the Great. Closure areas for the scheduled missile launches were broadcast to all maritime users in the region.
You've been reading too many Tom Clancy novels. Russian and American subs routinely open their torpedo tube doors. It is not an open invitation to being destroyed.
If that is, in and of itself, a justification for an attack, then you could say the same thing about the Pentagon and justify the attack on it on 9/11.
