The Boeing 767 was the first twin-engine widebody airliner from Boeing and debuted in 1982. Initial 767-200s were followed by stretched -300s and then further stretched -400s. The 767 featured a supercritical wing and an all-glass cockpit that eliminated old-fashioned round instruments.
As production continued, freight versions were introduced. The replacement for the 767 has already made its entrance -- the Boeing 787 Dreamliner. While the 767 continues in production, most orders are for cargo versions or military aircraft.
The military aircraft include a few E-767 AWACS radar planes for Japan and a few KC-767 tanker/transports for Italy and Japan. The U.S. Air Force selected the 767 as a new tanker/transport aircraft and introduced the type in service in 2019, but the program to buy 179 examples has been plagued by difficulties: delays and problems with a new refueling boom that uses video in place of the previous direct viewing by a boom operator. As of the end of September 2022, 48 had been delivered. The Air Force does not intend to replace all existing older tankers with the KC-46A but plans to hold future competitions for further tanker purchases, including a stealthy tanker.
