The Desert Storm portion of the 1990-1991 Gulf War lasted only 100 hours, not only because the combined land forces of the Coalition gathered against Saddam Hussein's Iraq was overwhelming and talented – it was – but it was also the contribution of two of the U.S. Navy's biggest floating guns that drew a significant portion of Saddam's army off the battlefield.
Shelling from the 16-inch guns of the USS Missouri and USS Wisconsin made it all possible, playing a crucial role in a conflict that would end up being their last hurrah.
Everyone knew a ground assault on Iraqi-occupied Kuwait was coming and had been for months. The only question for the Iraqis was where it would come from. Iraqi forces had been on the receiving end of a Noah's Ark-like deluge of bombs and missiles for the past 40 days and 40 nights. Iraq believed the Coalition would make an amphibious landing near Kuwait's Faylaka Island, when in reality the invasion was actually going into both Iraq and Kuwait, coming from Saudi Arabia.
If the Coalition could make the Iraqis believe an amphibious invasion was coming, however, it would pull essential Iraqi fighting units away from the actual invasion and toward the Persian Gulf. It was the ultimate military rope-a-dope.
The best way to make Saddam believe the Marines were landing was to soften up the supposed landing zone with a naval barrage that would make D-Day look like the 4th of July. The USS Missouri and USS Wisconsin were called up to continuously bombard the alleged landing beaches – and they sure made a spectacle of it. The Iraqi troops were supposedly shocked and demoralized, surrendering to the battleships' reconnaissance drones as they buzzed overhead, looking for more targets.
It was the first time anyone surrendered to a drone. No one wanted to be on the receiving end of another Iowa-class barrage. But the Marine landing never came. Instead, the Iraqis got a massive left hook that knocked them out of the war.
