The scenario uses an interwar aircraft development cycle of roughly three years. A first flight in 1933-34 could lead to an operational generation in 1936-37 and another in 1939-40. Designers would gain experience from building and operating the first aircraft while further testing continued. Those accumulated changes make the second generation harder to predict than a simple early copy of a historical aircraft.

Two aircraft generations before the war
A first flight in 1933-34 could lead to service aircraft in 1936-37 and successors in 1939-40, each drawing on accumulated experience.
