IAI1125 Astra, Gulfstream G100 & G150

Based on the Westwind, hence the old name Westwind Astra, Israel Aircraft Industries (IAI) developed the model 1125 Astra, with the wings under the fuselage instead of straight through it. Possibly as a result of that there is a long part of the fuselage without cabin windows, like on the Westwind. For the rest the Westwind and Astra are quite similar in appearance.

A remarkable feature of the Astra is long part of the fuselage without cabin windows.

Different versions

To differentiate between the different subtypes you have to look at

  • the shape of the cockpit windows
  • the presence of winglets 

IAI1125 Astra & Astra SP

The original version is the IAI1125 Astra. The Astra SP is a slightly improved version, but without external changes.

IAI1125 Astra SPX & Gulfstream G100

Apart from new engines the Astra SPX also received small winglets, so you can identify the subtype from the Astra/Astra SP. Since the acquisition by Gulfstream the type was/is marketed as the G100.

Remark: IAI built two Astra SPXs as C-38A for the USAF.

Gulfstream G150

Gulfstream significantly redesign the Astra SPX to create the G150. This is a G100 with a 12-inch wider fuselage, round cabin windows and different cockpit windows, more like the G200.

Gulfstream G150, essentially a Gulfstream G100 mated with a new, wider fuselage.

Confusion possible with

IAI1124 Westwind


Because the Astra is derived from the Westwind, you might mistake one for the other. Especially the tail and cockpit windows are very similar. However, the mid-wing configuration of the Westwind makes it clearly different from the low wing Astra.

North American Sabreliner


Given the triangular cabin windows on most Sabreliner versions and its low mounted horizontal stabiliser confusion is not likely. You might mistake a large cabin Sabre 75A or 80A for an Astra though, especially as the nose is comparable. But there are probably enough characteristics to keep them apart easily.

Cessna Citation

Another recognition error is possible with the cruciform tail Cessna Citations, in particular Citation V or Citation Excel series. While the general appearance may be the same, the Citations have straight wings, while the Astra has swept wings.
