yes, we do need boats, an alternitave to the PT
maybe the LCT boat could depart from the when cv is within 10-20 mile radius, then go directly near shore, the LCT could have a few auto guns and a few manned acks to defend it.
or its all one TG until 10-20 mile radius, then you are free of what to do, you can steer it just like a TG
