Next patch that will be coming out here soon will deal with units taking damage and radioing for assistance (when they have no contact). This is needed for harbor raiding as currently you may torpedo a unit and all the escorts and warships around the unit do nothing
This upcoming patch will make them react and come over to the unit that took damage and investigate. The patch will be very experimental and I will be releasing test versions of it for testing before final release. Expect a test version tomorrow
