SCAT-15F SST

From a 1965 Boeing report to the FAA. Boeing took the general aircraft configuration produced by NASA as the “SCAT-15F-220” and fleshed it out as a proper aircraft design. The SCAT-15F-B2 was the same design as the SCAT-15F-220 except that the fuselage was stretched to permit 215 passengers (the original seated 198). Gross weight was 430,000 pounds. The SCAT-15F-B7 was the final iteration, adding retractable canards for low speed control – the same thing was done with the Soviet Tu-144 SST, but in the Boeing design, the canard was a single-pivot wing. Cruise speed would be Mach 2.7, typical misison range 3476 nautical miles, and gross weight bumped up to 500,000 pounds, of which 226,500 pounds was fuel and 43,000 pounds was payload.
