I am sailing the incredible TypeXXI, in July'44, using GWX1.03.
However, the allied aircoverage is providing us many problems (as they should lol).
I want to do more travelling at schnorkel-depth...but at this stage - allthough already late-war - it can't have a RWR (Radar Warning Receiver) mounted on top of the schnorkel.
As far as I can tell, the FuMB37 Leros, which was especially designed for the XXI, only comes available in Jan.'45, which is rather late.
How can I make it available in July'44?
I already asked this question several times on SubSim.com, but no-one cared to answer.
