If you want ASW then C-130J can do it...

They'll even throw a MAD on the back for those that want/need it!
No, I don't work for LM, before anyone asks. I just want value for money and the C-130J would likely provide that and also keep Marshalls ticking along for a few years (and I don't work them either!).
