Aerion SBJ

The Aerion SBJ was a supersonic business jet concept proposed by the American firm Aerion Corporation. It was unveiled at the 2004 NBAA convention, and the company looked for a joint venture with an established business aircraft maker to carry a development cost put at 1.2 to 1.4 billion dollars. The design called for a conventional aluminium fuselage, a composite supersonic natural laminar flow wing and two existing Pratt and Whitney JT8D-200 series turbofans, carrying eight to twelve passengers at up to Mach 1.6 over about 4,000 nautical miles. Aerion reported about 50 letters of intent by 2010 but never built the aircraft. In 2014 the design was enlarged and renamed the Aerion AS2, and the company shut down in May 2021 for lack of funding.
