The Quickstrike was to fill the role of the A-6 Intruder after it was retired. This was not considered enough of an improvement by Congress, so the company shifted to the "Super Tomcat 21" proposed design. The Super Tomcat 21 was a proposed lower cost alternative to the Navy Advanced Tactical Fighter (NATF). The Grumman design would have the same shape and body as the Tomcat, and an upgraded AN/APG-71 radar. New GE F110-129 engines were to provide a supercruise speed of Mach 1.3 and featured thrust vectoring nozzles. The version would have increased fuel capacity and modified control surfaces for improved takeoffs and lower landing approach speed. The "Attack Super Tomcat 21" version was the last Super Tomcat proposed design. It added even more fuel capacity, more improvements to control surfaces, and possibly an active electronically scanned array (AESA) radar from the canceled A-12 attack aircraft. The last "Tomcat" variant was the "ASF-14" (Advanced Strike Fighter-14), Grumman's replacement for the NATF concept. By all accounts, it would not be even remotely related to the previous Tomcats save in appearance, incorporating the new technology and design know-how from the Advanced Tactical Fighter (ATF) and Advanced Tactical Aircraft (ATA) programs. The ASF-14 would have been a new-build aircraft; however, its projected capabilities were not that much better than that of the (A)ST-21 variants. In the end, the Attack Super Tomcat was considered to be too costly. The Navy decided to pursue the cheaper F/A-18E/F Super Hornet to fill the fighter-attack role. Notable F-14s preserved at museums and military installations include:  The Tomcat logo design came when Grumman's Director of Presentation Services, Dick Milligan, and one of his artists, Grumman employee Jim Rodriguez, were asked for a logo by Grumman's Director of Business Development and former Blue Angels No. 5 pilot, Norm Gandia. Per Rodriguez, "He asked me to draw a lifelike Tomcat wearing boxing gloves and trunks sporting a six-shooter on his left side; where the guns are located on the F-14, along with two tails." The Cat was drawn up after a tabby cat was sourced and used for photographs, and named "Tom". The logo has gone through many variations, including one for the then–Imperial Iranian Air Force F-14, called "Ali-cat".
