@ CrazyIvan,
I've read the email, and I agree with your proposal to use the UUV exclusively in ASW mode.
As for the detection curves, yeah I'm a little sad that we can't have a continuos (linear or mostly linear) detection range. But if the game is coded is such a way that the modders can't do anything around it we have to keep it as it is discontinuos jump and all.
Anyway your proposed changes make the UUV more "viable" as I see it. It has the right amount of sonar extension without competing with the towed arrays performance.
