This article refers to the entire Unryu-class; it is not about an individual vessel.

ww2dbaseThe Unryu-class aircraft carriers were based on the Hiryu-class design, meant to be used fleet carriers capable of embarking about 60 to 70 aircraft. Improved from the Hiryu-class design were the number of lifts (three lifts instead of only two), larger island structure, and the placement of the island structure on the starboard side (Hiryu-class ships had islands on the port side). Construction was approved in the War Construction Program of 1941 to 1942. Originally, a total of 15 carriers were planned, but by the end of the Pacific War only three were built and another three were incomplete.

Hayataka actually did not exist it came into the written record when the carrier Junyo's name was misread:

If you've identified it as a Shokaku-class carrier and you're choosing between the two, then I'd say "syukaku" sounds closer to "Zuikaku".
