Do modern subs ever come to rest on the sea floor?
As subs try to remain stealthy and quiet do they ever just settle and wait on the sea floor?
Thanks! |

That and they don't truly know whats down there below the keel, it may be muddy or rocky either way you don't want to sit a $1bn worth of kit on that. On the rocks it would rip an already stressed and compressed hull apart, and on mud it would act like a suction cup holding the boat on the bottom. Quote:
If a boat was on the bottom you would likely hear the metallic scraping of metal against rock (worrying) or the disturbance caused by a large stationary object against a current flow. However this is one for the sonar bouys here (see what i did there) they will be able to clear that up ET3R is a good chap and good source for that its his field. Quote:

In almost every case, there is tug support to bring the boat to the pier or, worst case the Skipper and Manuv. Watch OOD have enough experience to drive to the pier without the SPM. The only time an SPM is useful is if you're trying to dock in a harbor that has strong currents. As far as hovering, the 637's were really good at it and most 688's either have some type of negative tank that could be used to hover or else it was added later. If you look at a picture of a COW at work in control and there's something that looks like a joy stick on the side of the BCP desk, that's the control for hovering. :up: My last Chief had a knack for hovering 688's. All 688 COWs have to know how to do it, but some are better than others. |

Yes Seawolf (SSN 575) could, but that's a one off class and not representative of all. Halibut (SSGN 587) could as well, along with Parche (SSN 683), NR-1, and possibly Jimmy Carter (SSN-23). But these were all purpose built with the exception of Parche. MSW and ASW intakes on these boats would have to be on the upper portion of the hull to avoid sucking in unwanted material.
