It tells you there must be finite areas where the missles reach intended tarets and you can hide.

Generally, Boomers hide in deployment "boxes" - but those should be large enough to make this kind of a collision a high-odds proposition. More likely the SSBNs for the French and Royal Navies use the same underwater locations for fixing their positions based on geographic landmarks. So in this case the boomers went to those locations to get their fixes ... at the same time.

It's hard to navigate by landmarks when you're under water. Subs navigate through inertial navigation systems.

“Generally, Boomers hide in deployment “boxes”...”

I am amused you think everyone should understand your military jargon. I am especially amused at your references to “boomers”. You are of course referring to old hippies I presume?
