The "Wedgetail" is an airborne early warning & control ( AEW & C ) aircraft derived from the Boeing 737 airliner. It is in use by the Royal Australian Air Force and the air force of South Korea. Turkey has also ordered the aircraft.
Wikipedia has more information about the original.
This model is basically an upscaled version of my 1/1200 scale model of the aircraft. Some sectoins have been thinned down and the hull has been hollowed out, but no extra detail has been added.
