How far off the US Coast for a Russian sub to achive totoal surprise?

[miker42]

Greetings all. I'm new to the subsim community. I've been doing reserach for an "analog" game I'm designing and I have a couple of questions:

1. By today's standards, how close the US coast would a Russian Sub driver try to get to launch nukes and achive maximum surprise with as little reaction time as possible from the US. In other words, total surprise.

2. How would the US react and deal with such a threat?

3. What kinds of systems does the US have in place to fight off such an attack?

4. How would it be dealt with if the US had, say 30-60 minutes before any kind of MIRV seperation or impact?

Thanks,
Mike
