The Treaty, however, allowed two of the unfinished ships to be converted to carriers. They were the first operational aircraft carriers in the USN and were used to develop carrier aviation tactics and procedures before World War II in a series of annual exercises.

The fact they were not approved by Congress at the time of their initial request was due to political, not military considerations.
