Operational fitness explains the Swordfish's success without pretending it was fastest, strongest, or most advanced in every measure. Fitness comes from the combination of traits that best matches the environment. For the Swordfish, reliability, maintainability, and forgiving handling worked together within carrier routines. A rival advantage such as speed mattered less if it did not produce as many useful sorties or fit naval operations as well. The system an aircraft serves provides a better measure of its value than one headline specification.
