It had a 550-foot flight deck, about a long as modern-day guided missile cruiser.
Twelve coal-fired Scotch boilers propelled its two side-wheels to a top speed of less than 23 mph.
During WWII, the Wolverine, along with its sister trainer, the USS Sable, conducted more than 120,000 landings and qualified more than 35,000 pilots.
But the trainer carriers had a problem with what is called "wind over the deck."
When there was little or no wind on Lake Michigan, training had to stop because the carriers couldn't generate enough speed to support landings.
