The YF-14A 'Tomcat' at the March Field Museum is a preproduction A model, serial number BUNO 157990, and it is on loan from the U.S. Navy. It was number 11 of 12 test aircraft built. One of the many important tasks that #11 participated in was on the USS Independence, testing it's suitability for carrier use. It was transferred from General Dynamics - Pomona, along with the ground support equipment seen inside the museum, where it was used to mount missiles for test evaluation. It was towed on its landing gear in the middle of the night along Highway 60 from Pomona to March Field in September of 1992. (An F-4E, serial number 68-0382 in the foreground)
