Why a Fletcher-class destroyer was too small for useful aircraft launches

Could a Fletcher-class destroyer launch useful aircraft?

He regards the destroyer as too small: even an excellent hull cannot provide the clear length and deck area needed for practical aircraft operations without sacrificing its main functions.

The Fletcher class was an effective destroyer, but that does not make it a useful aviation platform. Launching an aircraft demands a minimum clear run, handling space, and freedom from the ship's weapons and superstructure. A destroyer hull has little reserve deck area once guns, torpedoes, machinery, boats, and sensors are accommodated. Adding meaningful aviation facilities would therefore displace capabilities central to the ship's actual mission. The brief answer supplies a lower boundary for hybrid-warship thinking: some hulls are simply too small to combine the roles coherently.
