  • Cost was estimated at $42 billion for 450 Navy and $31-$36 billion for 300-350 Air Force aircraft.
  • Supposed to be night/all-weather high-performance strike aircraft.
  • Also known as the Advanced Tactical Aircraft (ATA) to replace Navy and Marine Corps A-6 Intruder/EA-6B Prowler series.
  • The two General Electric engines were derived from the F/A-18 Hornet's F404s.
  • The ATA design featured "stealth" technology so that it would be difficult to detect on radar.
  • The ATA's avionics were to be controlled by an IBM computer using Very High Speed Integrated Circuits (VHSIC) technology and Central Processing Units (CPU) with 1.4 million words of memory and capable of 3 million instructions per second.
  • Westinghouse, with Texas Instruments, was to develop the AN/APQ-183 electronically scanned, phased-array multimode radar. Harris Corp. developed the multifunction antennas, to have been located in the wing's leading edges. Magnavox was supplying the A-RPX-5 Global Positioning System (GPS) receiver while Westinghouse was developing the A-12's combined-functions Forward-Looking Infrared (FLIR) system.
  • The maximum payload was 40% higher than that of the A-6, or 25,200 Ib (11,431 kg) vs. 18,000 Ib (8,165 kg), and 80% greater range.
