The four 1980s Iowa-class warships fired 1,083 sixteen-inch shells in the Gulf War — 759 from Missouri, 324 from Wisconsin. Against $1.7 billion in reactivation cost, that is $1,570,000 for every round the class fired. The 16 Harpoons per ship never left their canisters. Iraq had nothing afloat worth one. And there were of course those Tomahawks.
