I actually mean something more like "plausible" here. If primary means of protection for these subs is stealth, and that stealth is no longer in effect, then it's logical to assume that they're vulnerable. The fact that the US Navy is trying to replace them with stealthier Columbia class submarines is good evidence that this is true. Do you any useful information or ideas to add?
