At a minimum, to be taken very seriously, SH5 should include:
1. Baffles for all ship classes and types
2. Dynamic thermal layers that will vary not only mission to mission, but day to day as well
3. Depth Charge blinding for a reasonable period of time not only for the AI escorts but the players boat as well (and any other sonar equipped vehicle)
4. Detectable Echolot, and Sonar pings emitted from the player boat.
5. Surface clutter which would mask shallow running boats in very rough seas to some degree.
6. Other ship sounds should camouflage the sub's sound signature to some extent or another.
