Editing Atlas XH-1 Alpha (section)

==Development==
It was developed from an [[Aérospatiale Alouette III]] airframe, retaining that helicopter's engine and dynamic components, but replacing the original [[cockpit]] with a stepped tandem one, adding a 20&nbsp;mm cannon under the chin and converting the [[Landing gear|undercarriage]] to [[Conventional landing gear|tail-dragger configuration]].

The XH-1 first flew on 3 February 1985,<ref name="AI June 86 p299">''Air International'' June 1986, p. 599.</ref> and soon embarked on a rigorous flight test program to examine the feasibility of a dedicated attack helicopter in southern African conditions. The results were ultimately good enough to convince Atlas and the [[South African Air Force]] to go ahead with the development of a dedicated attack helicopter, the [[Denel Rooivalk]].

The XH-1 and Rooivalk are completely different aircraft and share no components. The Rooivalk was developed from the later XH-2 prototype.

The sole XH-1 was retired sometime in the late 1980s and was handed over to the [[South African Air Force Museum]], where it remains to this day.{{citation needed|date=July 2018}}
