Overview
Program history
The new-build JetStar II entered operational service in 1977 with four TFE731-3 engines. Lockheed demonstrated extended nonstop missions and emphasized lower fuel consumption and cabin noise. Earlier aircraft could also receive a separate 731 conversion; those modified aircraft share the engine concept but should not be described automatically as factory-built JetStar IIs.
