Hōshō and Hermes show how the first purpose-built carriers began turning experiments into mission-led ships. Hōshō's folding funnels solved smoke interference with elaborate machinery where taller funnels would have been simpler and lighter. Hermes receives more credit because her island, cruiser-derived hull, and 25-knot speed supported a deliberate role accompanying cruisers around the world. Her slow construction alongside Eagle delayed the lessons, but the finished ship offered a coherent cruiser-carrier concept rather than aviation equipment added without a clear purpose.

The first purpose-built carriers expose the importance of tall funnels, clean airflow, island structures, and designing a small carrier around a coherent cruiser-support mission.
