The Jet Commander was designed and built in the United States initially by Aero Commander. When the company became Rockwell the US Government decreed that a single manufacturer could not build two models of executive jets concurrently (as Rockwell also built the Sabreliner) and so production rights were sold to Israeli Aircraft Industries with the aircraft being re-named the 'Westwind'.  Many of the early aircraft have now been withdrawn from use and scrapped due to their age.  The Astra aircraft is currently built in Israel.
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 

First flown on 27th January 1963, the 1121 6-8 passenger aircraft  has General Electric CJ610-1 engines giving it a range of 1867 miles.  The basic model has four starboard and three port windows. < N525AW was an RC1121A

This model has four windows each side of the fuselage and around 24 were built.

This was the stretched and upgraded version of the Jet Commander built by IAI, beginning at c/n 151. It has six starboard and five port windows plus tip tanks
.

IAI 1124 Westwind I

This model is powered by the larger, more powerful TFE731 turbofan engine but retains the tip tanks of the 1123.  The Westwind I superseded the 1124 giving increases in fuel and cabin capacity and production began at c/n 187.  Around 160 of this version were produced.

.

IAI 1124A Westwind II

Most easily identified from the winglets on the end of a new wing, almost ninety of this version were built, concurrent with the Westwind I of which it is a longer range version with other additions. Powered by two Garrett TFE731-1G turbofans, range is 3345 miles with four passengers although up to ten can be accommodated.  It first flew on 24th April 1979.

.

IAI 1125 Astra

Powered by two Garrett TFE731-3B turbofans, the Astra followed on when the Westwind production ceased.  It can accommodate up to nine passengers and was first flown on 19th March 1984. It consists of the fuselage, engines and tail of the Westwind but with a new, low mounted wing. About 34 of the original model were built before being superseded by the SP.  Aircraft are built in Israel and flown to the USA for fitting out.

.

IAI 1125 Astra SP

This version has a new interior, wing and upgraded avionics compared to the basic model, but is externally identical.  It first flew in August 1994 and about sixty had been built up to late 1997, including two specially converted versions for the US Air Force, designated the C-38.  It is powered by two Allied Signal TFE731-40 turbofans.  Production fell into the hands of Galaxy Aerospace in 1996 and up to eighteen aircraft are intended to be built each year.

IAI 1125A Astra SPX / Gulfstream 100

The first model SPX was c/n 073. It is powered by the uprated TFE731-40R engines and features a revised interior and winglets. Aircraft from c/n 079 onwards have been built to this specification.  Gulfstream Aircraft Corp purchased the range in mid 2001, redesignating it as the 'Gulfstream 100'.  Around 150 had been built by mid 2004

C-38A Astra SPX

Two Astra SPX have so far been acquired by the US Air National Guard for transport operations out of Andrews AFB. An order for at least two more is envisaged.

Galaxy Aerospace IAI 1126 Galaxy

The latest offering from IAI, the Galaxy is built in Israel and initially flown 'green' to Alliance, Texas  where they were fitted out for delivery. However, on the purchase by GAC the fitting out was moved to Dallas Love Field.  Galaxy Aerospace was formed as a joint venture between IAI and the wealthy Pritzker family.  The Galaxy can accommodate up to nineteen passengers over transatlantic ranges.  Powered by P&WC PW306A turbofans, the aircraft was originally to be built in co-operation with Yakovlev, but this was abandoned when Yakovlev was unable to keep the original schedule.  The aircraft was rolled out on 4th September 1997 and first flew on 25th December 1997. Gulfstream Aerospace purchased the model in mid 2001 and redesignated it as the 'Gulfstream 200', to fill a gap in GAC's aircraft range enabling it to more effectively compete with Bombardier .
