North American NAC-60
The North American NAC-60 was the first American supersonic transport project. The development took place in the 1960s as part of a government-funded design competition to build an American SST as the joint Anglo-French Concorde and the short-serviced Soviet Tupolev Tu-144 was underway. The design, however, was rejected in favor of the Lockheed and Boeing designs, allowing them to get further study.Design
The North American NAC-60 had a set of canards at the nose, but this was essentially a scaled-up B-70 Valkyrie. These would provide extra stability or control, replacing the tail. As the NAC-60 was an SST, no horizontal stabilizer was needed, while the Concorde it was meant to compete with had a wing specially designed for both subsonic and supersonic flight, which, as a result, did not need a canard.
