I do not know whether it was ever adopted, but it was tested.
Nope - may have been tested but the TLAM comes in a submunition dispenser (area denial) - A solid warhead (conventional) and of course the crowd pleasing portable sun variant with the W-80 warhead. I know of at least one other special payload it has carried but I see no reference to it on the web so I won't discuss it but it wasn't DU.
