Dassault Mirage 4000 Model 3D

Derived from the Mirage 2000, the Mirage 4000 was larger and heavier than its single-engine forebearer. Built around two SNECMA M53-2 turbofan engines, the Mirage 4000 was further distinguishable from the Mirage 2000 by the small canards above its engine intakes and the addition of a true bubble canopy. Of course, despite the differences, the two Mirages were quite alike. Both aircraft featured a delta wing and semi-conical Oswatitsch-type air intakes. The Mirage 4000 measured 61 feet long with a 39-foot wingspan, 19-foot height, and a wing area of 790 square feet. Only one Mirage 4000 was ever built. It flew in the 1980s before the project was canceled and mostly forgotten, leaving aviation enthusiasts to wonder what might have been.
