Development Examples

Just to assist in keeping some of the development histories straight:
  1. CH-53A. First flight October 1964. First USMC production aircraft deliveries in fall of 1966.
  2. UH-60A. First flight in October 1974. First production deliveries to US Army in October 1978. And that history includes a full fly-off competition with Boeing, with an evaluation period following the fly-off and then getting production going.
  3. S-76A. First flight in March 1977 and following FAA certification, the first delivery to Air Logistics took place in February 1979.
  4. S-92A. First flight in December 1998, with FAA Certification in December 2002 and first delivery in September 2004. This longer development history was controlled by available corporate finance, with the program coming to a stop about four times as I recall.
Just one more note re the CH-53K. Its a whole new aircraft. It looks like the "E", but the similarity ends there.

Thanks,
John Dixson
