Assigned to 10th Flotilla in Lorient (Gwx3), with a IX-C to patrol CA76! Thats around Norfolk and New York
Currently heading straight west at engine 2/3s. Efficiency is important, my navigator gives me 34000km of range with this speed. Good enough..
Emergency dive drills were around 50 seconds for a 17m depth, that's when the stern is almost in the water. Still very vulnerable IMHO, so I say a minute at least.
We got the biscay cross so relatively aware of approaching planes. Stayed surfaced at our first warning, battled it out with a Wellington, managing to down it, but I got the message, never will push my luck again.. Certainly dive if I have the time..
