In 1990, I was in a conference in St. Louis, Missouri and I saw a museum ship was nearby. I didn’t have the money to visit and thought I would go back one day and visit it. But the 1993 flood destroyed any future opportunity to visit it. The ship was USS Inaugural (AM-242): https://en.wikipedia.org/wiki/USS_Inaugural_(AM-242), one of only two ships of its class that were still around in 1990. You can also learn more about it and its fate at http://ussinaugural.org/. You can see it on Google Maps at https://www.google.com/maps/place/USS+Inauguralemail@example.com,-90.1902946,547m/data=!3m1!1e3!4m5!3m4!1s0x87d8b3000d4f5b93:0x29201eb9805c7011!8m2!3d38.6114738!4d-90.1881006.
The other surviving member of its class is the USS Hazard – https://en.wikipedia.org/wiki/USS_Hazard_(AM-240) and it’s probably safe from flood issues as it’s on dryland. You can learn more about it at https://parks.cityofomaha.org/parks/freedom-park. It’s closed for the season and the park includes USS Marlin (SST-2) and a few other items:
Admission is free.
Tours are available most Saturdays from 10 a.m. to 3 p.m., April through November. Please check the Freedom Park Facebook page (link below) for more information. View map and directions HERE.
