The YouTube channel TheOperationRoom has a very well animated play by play (almost to the minute) of the air and ground war in gulf war 1 in Iraq/kuwait. In one of the videos he mentions tomahawks having to take a long route into Baghdad because it was the only one with enough terrain for the missile to follow to the target. This was 1991 so maybe older inventory.
