Interestingly enough the US is considered to be in a rather bad spot with anti-submarine warfare, especially non-nuclear submarines. Carrier groups have limited ability to counter advanced diesel-electric and air independent propulsion submarines. It's especially bad in littoral areas. The US Navy has the majority of their ships used up in BMD, drug enforcement, etc. etc.. There is very little ASW training done. There are no S-3 Viking ASW resources, carrier/ship based helicopters are now "multi-purpose", P-3 Orion patrols are well... land surveillance & communication relays, T-AGOS is heavily reduced, and SONUS is a bust. The US Navy is severely weakened against submarines and sea mines since the end of the cold war.
