Measuring technological trends: A comparison between U.S. and U.S.S.R./Russian jet fighter aircraft

Abstract

Measuring and forecasting technological change is a crucial issue from various points of view. This is particularly important in the case of weapon systems as this would enable technological performance and operational capabilities to be assessed in relation to potential threats. This paper measures and compares technological trends in U.S. and Soviet Union/Russian jet fighter aircraft by estimating the relationship between the first flight date and a set of performance and technical characteristics of these aircraft. From the point of view of technological advantage, we find that U.S. jet fighters were, on average, approximately 2 years ahead of the former Soviet Union/Russian jet fighters during the entire jet fighter era. Nevertheless, the technological advantage has swung from one side to the other during specific periods as particular models have been introduced. Finally, the development of 5th-generation jet fighters, in particular the development of the F-22 Raptor, has placed American technology about 20 years ahead of Russian technology, a difference that has never occurred before. This finding casts doubt on the ability of Russia, as the inheritor of the former Soviet Union aircraft industry, to match American technological progress in jet fighter aircraft.
