I'm quite interested in this topic. However, there are some concerns I have.
First of all, the UUV is indeed powerful. But even with the crippled torpedo passive sensors, do people here remember what happened when the torpedoes got the feedback flag set?
It may be that the immense range is... a bug.
Secondly, keep in mind the purposes of the UUV when making changes.
Do we want to tune down its passive detection capabilities?
Do we want to increase its minefield mapping capabilities?
Etc.
I'd say yes to both, but with moderation; how often do you run into a minefield?
Third, there are some areas of the UUV that are definitely on the weak side. If you want to have a viable tool for minefield navigation, the speed (and with it, the range) needs to move up, and the active sonar which is not much better than a torpedo could do with some improvement. Given that it has much less propulsion and warhead, a better sensor than torpedoes doesn't sound like asking for much.
Perhaps an idea is to tone down the passive side, and up the active side? If the UUV goes active, its presense is known to the enemy (presuming the enemy has subs or AI... but that's a gripe for another time)
I haven't used the UUV in active mode since... well... I sorta just know I have at some time, but by what I can tell that may as well have been with SC...
Current minefield mapping and navigation performance is quite lacking.
As to the "5ft sensor stuck to the end of a torpedo body" I always imagined the UUV as having sensor packages sandwiching the elec/propulsion "core".
In the seawolf, at least, I wish one could see what the uuv sees by it appearing as a last sensor, along with sphere, hull, and towed. Interface-wise it would be a small difference, and game engine-wise it shouldn't be so much different from sonobuoys. But the other platforms might not have that easy a time with it.
