Wet Navy Laser and Sensor Floats

[pzmcgwire]

Just found the 3rd part of Wet Navy in Challenge #60 and see that at TL12, submarines use laser floats and sensors that are detached from the sub. With detached floats assuming cables that aren't excessively long (2 km or less), what's to stop an orbital force from just dropping a nuke on a firing laser float's location, setting it for an underwater explosion to catch the firing sub?

If tech can be advanced enough, could the cables be extremely thing and then allow for multi-km lengths so as to avoid having a nuke dropped on the firing location, but that would risk entanglement with other objects. What would be the maximum feasible length of a cable to connect sensor and weapons floats to a submarine?

Also it seems that there was no other weapons proposed beyond TL12. After that point, submarines become the equivalent of SDBs, and since SDBs don't seem to have any mention of detachable laser and sensor floats, are those remote floats just a limited technology implementation replaced by RPVs with meson communicators?

You don't want to be caught in an explosion underwater.

I would guess the submarines themselves are drones, if they're exposing themselves to possible counter battery fire.

You could have a towed array, and launch wires, sensors, and weapon platforms from there.
