The Museum of Flight seems to have two examples of the air launched cruise missile.  This is the Boeing developed AGM-86 missile.  One of them is hanging from the roof in the main museum complex while the other is in the restoration facility up at Paine Field.  I don’t know which versions of the missile they are.  Some were nuclear armed (this version remains in service I believe) while others had a conventional warhead (and I read that these were retired recently).  The missiles were widely deployed on B-52s and B-1Bs but I understand that only one wing of the B-52 now has them.
