Gothaer Waggonfabrik was the company selected to mass-produce the Horten Ho 229 as the Go 229. They began work on an improved version of the aircraft after discovering flaws with the Horton flying wing design. Gotha proposed three versionsof the P-60 with the P-60C as the night-fighter version. This is a full scale mock-up of how it would have looked and is on display at the Luftfahrttechnisches Museum Rechlin.
