No information on this beyond this piece of artwork, and speculation. UTTAS stood for “Utility Tactical Transport Aircraft System,” the US Army program to develop a successor to the Huey… which led to the successful Sikorsky UH-60 Black Hawk. Boeing Vertol delivered three prototypes of their YUH-61 UTTAS competitors after a contract awarded in 1972, so clearly this artwork has to precede that.
