The dimensions, weights, engines, and speeds of successive Fairey III variants show why raw horsepower never tells the whole story. Power-to-weight ratio mattered because a larger engine could add enough mass to reduce the benefit of its extra output. The III F's advantage at 10,000 feet is more revealing than its lower sea-level speed, since useful speed aloft supported endurance, scouting, and spotting. An aircraft optimized for bombing or strafing would place greater value on low-altitude performance. Reading the figures this way connects the specifications to the aircraft's intended naval role.

How Fairey III performance choices reveal its reconnaissance mission
Engine power, weight, and speed at altitude show why the Fairey III evolved toward spotting and reconnaissance rather than low-level attack.
