The YO-3A is a low altitude SILENT STEALTH night reconnaissance airplane that was developed for the U.S. Army for use in the Vietnam War. NASA acquired this YO-3A in the mid 70's and converted it to a flying microphone.
This prototype F-14 was delivered to the US Navy in 1972 as number 11 of 12 test aircraft. It participated in carrier use suitability on the USS Independence. It was retired in 1982 after 1,264 flight hours.
