Yeah, I don't have the book in front of me right now to remember what the book read exactly, but iirc, the americans launch their missiles, and a previously silently sitting ASW ship is sittting undetected nearby that causes trouble for the subs.
I was presently surpised the first time I saw the replay of the mission. Nice improv to achieve the plot.
I do remember something in the book about the cargo ship in the mission too. Something about it being a electronic ship disguised as a civillian ship, but I can't remember what the importance was... anyone have the book onhand?
