The next installment of the exclusive CS collection of the 777 airframe/engine variants is a digital replica of the Boeing KC-777 Tanker Transport.
In September 2006, Boeing announced that it would produce the KC-777 if the USAF required a larger tanker than the KC-767, and proffered that the KC-777 would be based on the 777-200LR. The KC-777 would be the largest tanker ever built and provide global strategic refueling and transport capability.
