UAP

abbreviation or noun

ˌyü-ˌā-ˈpē 

plural UAP or UAPs

… UFO has been replaced by UAP. Scientists and government officials are using the new acronym in an attempt to get away from the stigma and assumptions of little green men that persist when people think of UFOs. Until recently, UAP stood for "unidentified aerial phenomena," but last year's National Defense Authorization Act tweaked the term to stand for "unidentified anomalous phenomena," a broader catch-all category.
