Excellent bit of kit LJ, the concept is only spoiled by the fact that the sonobuoys need to be in the RF horizon of the ship in order to pass the information back. The effective range of a modern heavyweight torp is? I think you'll know there is a sub out there by the bang before the buoys get contact.
Just done the calcs and T23 rf horizon for a sonobuoy is 10nm.
