Talk:List of light aircraft carriers by upgraded maximum stats/@comment-26399913-20150910163707/@comment-25459687-20150910174348

to add on to Spartan-055's post, several of the CVLs were converted from merchant ships, and therefore did not have engines adequate for military duty. The smaller carriers spent a lot of time being used as plane ferries because of this. Houshou, of course, was just an older ship that had been built before the need for 30+ knot speed for launching aircraft was apparent.
