but your big fat attack sub would have to be indeep enough water to be submerged, and les than 25 miles from the target.

limited oportunities methinks

 

maybe a unmanned remote controlled submergeable nlos launcher?

that would be ok in about 10' of water

Thats what I was getting at - a UUV NLOS launcher. It would be carried by a mother sub, released some 50 miles from its "parking" position, guide itself to that position, sit on the bottom until the appropriate time, then surface and launch. The vehicle would be of minimum size for propulsion, NLOS, and sensors. It could  perhaps have various sensors and/or retractable antenna for communication to decide when to attack.

 

Perhaps for dealing with surface threats in the area, its sensors could detect ships in an area and surface to attack them - much like a mine except covering an extremely large area. The NLOS-LS LAM's would have been good for this. If you hear a ship, send up a few LAMS in the general direction.  A system like this could provide a type of area denial on the sea without having to lay mines all over the place.

Problem with the NLOS-LS as a "mine" of course is that they're probably not big enought to do major damage to anything but smaller vessels. 

 

Might be interesting if this UUV carried some 2 to 4 torpedos instead. But autonomous underwater targeting might be more of a problem.

Simple in concept, difficult in design, but what is the mission?

 

30 to 45 PAM's is prrobably too much firepower for a raid, and for anything else you could just unload the NLOS-LS containers on the beach and fire them from there.

 

10' of water depth will not hide the launcher, even in the dirtiest estuary.

 

Wave action will be a major problem during firing if the waves break over the top of the launcher.

 

But is suspect that the biggest problem will be the suceptability of the launcher to a mission kill from the common fishnet.

 

Use stand-off missiles from aircraft or arial drones.  They are more flexible an easier to retrieve if not used.
