Lockheed JetStar II
Lockheed Corporation · United States · first flew 1976 · transport aircraft
The Lockheed JetStar II was a re-engined development of the original Lockheed JetStar business jet, replacing the four Pratt & Whitney JT12 turbojets with quieter and more efficient Garrett TFE731 turbofan engines. It retained the original aircraft's distinctive four-engine rear-fuselage configuration and wingtip tanks.
Recognition (WEFT)
| W — Wings | Low-mounted, swept |
|---|---|
| E — Engines | 4 × turbofan, fuselage-mounted |
| F — Fuselage | Business jet with four engines mounted in pairs on rear fuselage |
| T — Tail | T-tail |
WEFT is AircraftIQ's four-point recognition method — how it works.
Spot it by:
- Business jet with four engines mounted in pairs on rear fuselage
- Distinctive tip tanks on low swept wings
- Re-engined JetStar with Garrett TFE731 turbofans replacing original P&W JT12s
Unmistakable with four engines clustered in pairs at the rear fuselage, large underwing tip tanks, low swept wings, and a T-tail — a configuration unique among business jets.

History
The original JetStar first flew in 1957 and became a successful executive transport, also serving with the USAF as the C-140. The JetStar II was introduced in 1976 with the TFE731 engines, significantly reducing noise and fuel consumption while improving range. Existing JetStars could also be converted to JetStar II standard. The type served US government and military customers as well as corporate operators.
Variants
The JetStar II was itself a re-engine of the JetStar 8 and JetStar 731; conversion kits allowed older airframes to be upgraded. The USAF C-140A/B were military variants.
Where you'll see it
Used by corporate operators and the US government; the USAF operated examples as VIP transports and calibration aircraft.
