Passive Mk48 problems?

Make sure the torp speed is no greater than 45 knots.

Even at a reduced speed, passive torps might not acquire subs in LW/Ami. Passive torps are primarily ASUW weapons, and will only perform well against the very loudest of submerged contacts.

Yup.. that's it. I guess I over-estimated the seeker on the Mk48 (or under-estimated the noise generated by its propeller at 55kts) as I thought that at point blank range the Oscar would have been loud enough to detect.

The axial-piston engine on the Mk48 is very loud, but also the flow noise of the water over the nose of the torpedo when it is moving above a certain speed washes out the passive (and eventually active) sensor.
