By 1968, 10 pre-production units (serial numbers 66-8826 / 8835) were delivered and others 375 units were approved, but meanwhile the Army acquired AH-1G Huey Cobras, a private - venture design of Bell.

Finally, by the end of 1969, with Cobras already in Vietnam, the US Army cancelled the AH-56s request.
