Production of the venerable 707 airframe ended in May 1991. Following studies of the most suitable follow-on aircraft for the AWACS mission, Boeing announced in December 1991 that it would offer a modified 767 commercial jetliner as the platform for the system. The 767-200 provides several advantages over the 707. Because of its wide-body configuration, the 767 offers 50 percent more floor space and nearly twice the volume of the 707. The 767 can carry a heavier payload, has a greater range and flies higher than the 707. 767 AWACS will have mission capability comparable to the 707 AWACS and will be interoperable with the AWACS aircraft currently in service.
