The so-called "Quickstrike" was a proposed long-range strike fighter version of the F-14D Tomcat, designed to fill in the gap created by the cancellation of the A-12 as a possible A-6 Intruder replacement. It was envisaged as a sort of naval equivalent of the Air Force's McDonnell Douglas F-15E Strike Eagle.
The Quickstrike was basically a minimum-change F-14D Tomcat equipped with FLIR capability and provided with more modes for its APG-71 radar. These additional modes included synthetic aperture and Doppler Beam Sharpening for ground mapping, making the radar more similar to the APG-70 of the F-15E. There would be four hardpoints under the central fuselage which would each carry five munitions substations, whereas the two wing glove pylons would have two munitions substations each. Navigation and targeting pods would be provided that would be similar to those already carried by the F-15E. The cockpit would have FLIR, HUD, and moving-map displays for the crew. The aircraft would be capable of carrying and delivering laser-guided bombs, stand-off SLAM missiles, and Maverick air-to-surface missiles. HARM antiradiation missiles and Harpoon antiship missiles could also be carried.
However, the McDonnell Douglas F/A-18E/F was selected as the successor to the A-6, so the "Quickstrike" derivative of the Tomcat was not proceeded with.
