How the SM.79 generated usable air strength

The SM.79 turns aircraft design into a force-generation problem. It supplied much of Italy's bomber and strike strength, and its airframe was sound and reliable, although engine selection constrained performance. By June 1940, 612 had been delivered across fourteen wings, some of which mixed SM.79s with other aircraft. A typical squadron held ten assigned airframes but expected seven or eight to operate, while a wing might turn roughly thirty of forty assigned aircraft into usable strength. The remainder covered maintenance and second-line machines instead of assuming every airframe could fly. A rugged, adaptable type gave Italy a practical way to assemble air power for sustained Mediterranean operations.
