For clarification, ASPECT has a much greater affect on active sonar returns than anything else. Think of the ship as a piece of paper - if it's flat towards the ship going active, that's a lot of surface area for the sound to reflect from. End on, however, greatly reduces the return.

Also, US SSN's do not carry MOSS..

Not anymore - but I think they were a new wonderful thing in the 80's when this is set. If that's the case (haven't looked it up, CBA to do it right now...) then it's still a valid question...
... that I don't have an answer to.

Yes and no. I worked at SOSUS in the PAC side of the house, and we used airborne assets to track boats fairly often. The trick is that they have to know WHERE to look. Basically, we'd pick them up on LF PNB, determine a position to within XXX nm circles, and sick the airdales on them. When they know where to look, they are VERY good at their jobs.
Of course, in this game, they ARE way better than they should be... who's sending them position data? Of course, if you launched a TLAM/TASM/HARPOON then that's a dead give away, but otherwise, they suffer as Shipkiller noted.
