A liberal crappola news report I read yesterday claimed that the Tomahawk uses a depleted uranium warhead, as do many of the bombs being used. Complete and utter BS.
Rocky - I have been out of the loop in this area for a number of years, so I do not know what the current situation is, but depleted uranium was at one time tested in the nose of a Tomahawk to aid penetration of hard targets before the explosive warhead exploded.
I do not know whether it was ever adopted, but it was tested.
