The A-6G Intruder was to have been a less expensive alternative to the A-6F, which
had been cancelled in 1988. It had most of the A-6Fs improvements but not the General Electric F404-GE-400D turbofans.
The third A-6F (BuNo 162185) was kept flying to in support of the A-6G, but no production was undertaken.
