- Production164 turbojet powered JetStars built by mid 1973. Lockheed built 40 new build turbofan powered JetStar IIs from 1976, while Garrett converted an additional 61 to JetStar 731 configuration. Approx 29 JT12 powered JetStars, 39 JetStar IIs and 48 Garrett converted JetStars in service at late 1998.
The four engined Jetstar was at first outlined as a private wander yet was additionally chosen to satisfy a US Air Force necessity for a multi engined light transport and team mentor.
The principal Jetstar model first flew on September 4 1957. Two models were manufactured fueled by two Bristol Siddeley Orpheus turbojets, one of these was reengined with four Pratt & Whitney Jt12s in 1959 when a consent to permit gather the Orpheus in the United States couldn't be arranged. The Jt12 was chosen for generation flying machine, and the first of these flew in mid 1960.
The principal common arranged Jetstar was conveyed in right on time 1961 thus the Jetstar was the first business plane to enter administration. In the interim the Jetstar entered administration with the USAF in 1962 as the C140 navaid alignment air ship and the Vc140 VIP transport in late 1961.
The turbojet controlled Jetstar stayed in generation until mid 1973, by which time advancement of the turbofan fueled Jetstar II had been published. The Jetstar II contrasts from the prior air ship basically in its four Garrett (long ago Airesearch and now Alliedsignal) Tfe731 turbofans with their altogether enhanced fuel utilization, bringing about significant upgrades in working expenses, run and lower commotion levels, while more power permits a higher most extreme takeoff weight.
The main Jetstar II flew on August 18 1976, with affirmation following in December that year. The II stayed in generation until 1979.
Airesearch then had as of now flown its own particular Tfe731 fueled change of the Jetstar in July 1974. The principal generation Airesearch 731 Jetstar transformation flew in March 1976.
