As you can see, despite being designed a good decade after the destroyer and cruiser, each LAC is an inferior unit. However, if eight Faiths can be deployed instead of one Austin, the opening missile salvo in a fleet engagement would be roughly 20 times heavier for the same amount of tonnage, at the expense of not being able to contribute to a subsequent missile salvoes.
