The MH-60R is the only afloat ASW asset.Interestingly enough, the primary submarine detection, tracking, localization and classification device on the Romeo, the AN/AQS-22 Airborne Low Frequency Sonar (ALFS) was built by... You guessed it! The French!
What I cannot understand is the deliberate destruction of the battle group's ASW assets with no replacement. It is as if the Navy's brass has elected to put all their best and most expensive surface ships on the chopping block for the growing Chicom Navy threat in Asia.
