Rank 58 is the rank following Rank 57. No new researchers unlock at this rank. One must complete at least 14 of the 17 missions available to move on to Rank 59.

The next rank, Rank 59, will require you to upgrade 4 researchers, so make sure you save some cheap researchers to upgrade then. Also, the next rank has the first Battleships mission, so if you cannot get bullets to YY or ZZ, upgrade Johnny O. Rambo or Ann Munition.
