Not sure if anyone is interested, but there were three US aircraft carriers at the Battle of Midway (June, 1942): the Enterprise (CV-6), the Hornet (CV-8) and the Yorktown (CV-5). The Cape Esperance (CVE-88) did have hull number 88, but did not enter the war until 1944 and was an "escort carrier," a type of bargain basement aircraft carrier which could be built quickly in greater number, but which were slower and much smaller than the larger fleet carriers.
I'm guessing that the carrier in the original game was hull number 88?
This bit of pedantry brought to you by random access memory of US carrier operations in WWII, and wikipedia.
