UFO 1 is the debut album by British rockbandUFO. It was first released in the UK by Beacon Records in October 1970. The first US release was on Rare Earth Records in April 1971. Neither of these releases charted; however, the album did become a success in Germany and Japan.
The album was reissued under the name Unidentified Flying Object with 4 of the 5 tracks from the band's second album. This reissue incorrectly shows a photo of the band from the 1980s on the cover.
The album was also reissued on the Flying, The Early Years compilation, along with all of the band's other pre-Schenker work. It was also given a straight reissue under the name All The Hits & More - The Early Days (XXX Media, Germany, 2011), with no additional tracks.
