Who needs sailors anyway?

[Kirkhill]

That more or less defeats the purpose, no?

I don't think so. One "frigate" becomes its own task force.

4 to 6 LUSV at 80 to 100 m
A couple of XLUUV.
A field self propelled sailing and gliding (underwater) sensors.

Risk is not eliminated but it is radically reduced.

Could be wrong. But that it is what I am taking from the info available.
