No.. actually the Missouri is an Iowa Class battleship in the same class as the NewJersey... both of which were built and launched in the interwar period... the Minnesota was a much earlier design laid down in 1906 or 09.... pre dreadnaught/super-dreadnaught ships such as the Missouri... super battleships didn't come into planning till several years after ww1 ended and most didn't enter active service until just before ww2.... by the end of WW1 the Minnesota was a second class battleship at best and was sold for scrap before the Missouri's keel was even laid... eventually the term "super-dreadnaught" battleship was simply reduced to battleship... giving us what we know as battleships today...
