USS Wisconsin 1988-1991

The 16″/50 caliber Mark 7 guns aboard the USS Wisconsin were the last ones fired from a US battleship in support of American troops ashore.

And they are big — really big.

The guns are 16 inches in diameter, 800 feet long, and weigh about 292,000 pounds with the breech and yoke assembly, the curator of the USS Iowa Museum, Dave Way, told Business Insider.

They fired two basic rounds: 2,700 pound armor piecing rounds and 1,900 pound high capacity shore bombardment projectiles.

We recently had the chance to see these guns aboard the USS Wisconsin in Norfolk, VA.

Iowa-Class battleships served from World War II until the Gulf War and were equipped with nine 16″ guns.

We saw these massive guns on the USS Wisconsin.

Even without firing, they look pretty powerful.
