Wow--the american fleet is being pounded. How many BBs and CA's have you sunk?
Also--what is with the German fleet-where di they go? Australia?
FInally-I think regarding transports-you only loose troops if they begin to exceed the fleet's transport capacity. I invaded Greece with the USSR and lost some transport boats to the Italian Navy. I was already at max capacity. One of the Marin divs lost 2 of it's brigades (I had three transports and three marine divs+HQ).
Those fuel levels are alarmingly low although you probably have quite a few barrels lurking in some remote island supply depot.
