Costs (Kosten)
It was rumoured that a SSBJ will sell at around 500 million Francs (83 million US-Dollars).
Dassault had spent about 5 million US-Dollars when the studies were terminated in the spring of 1999.

Remarks (Bemerkungen)
After revealing plans to study a supersonic business jet at the NBAA convention in 1997, Dassault went on to give more technical details of its design on 19. May 1998 at the Maintenance & Operations Seminar in Nice.
On the technical side, Dassault has choosen an ovoid fuselage cross section to combine comfort and low drag. The wing has a double-delta planform, coupled with canards. Construction will be mainly in conventional aluminium alloys, thus necessitating the speed limitation of Mach 1.8, which the manufacturer deems fast enough. Typical travel times (including one hour fuel stops) should be eight hours from Los Angeles to Hong Kong or 8.5 hours from Sydney to Los Angeles.
The realisation of a supersonic business jet depends heavily on factors like environmental concerns and thus overflight rights. Dassault claims that the sonic boom, for example, will be much less than with Concorde (less than half, it is claimed). Also, noise levels at take-off and landing should be less, as there are no afterburners needed. A US partner seems to be mandatory for market access there and to share development costs.
After technical studies, which included work on different engine concepts, Dassault said that it could not find a suitable powerplant. Military engine derivatives were rejected because they were not designed for extended supersonic periods, and all-new as well as modified civil engines were much too expensive to develop. On the other hand, Dassault claimed that many other technical questions were resolved. Nevertheless, work on the SSBJ was terminated in March 1999.
