Primary road is doing a spot of drug interdiction and helping out after a hurricane.
A Bay class LSD is a better option for that role. It's not as if they are contemplating actually fighting a naval action.
It's not a secondary mine countermeasures role. You self sweep your own path in a transit or a landing operation where you will have to stand inshore. It's an organic capability.
And who's conducting ASW for you whilst you do this?. It makes more sense to leave the Frigate doing its job and bring along a river or 2 with the MCM stuff.
