The original assessment plan expected it to fly between 1,200 and 1,700 flight hours during 77 fly days. At the end of the one-year MUA period, the aircraft had only flown 54 sorties to accumulate approximately 673.2 flight hours. Of these sorties and hours, 22 sorties and 389.6 flight hours occurred during the course of a scheduledexercise. The small number of flight hours affected both the level of integration in joint and combined exercises (full integration was never achieved) and reduced the confidencein the observed suitability parameters.
