Complete L-1011 Family:
-300, -400, and -600 were never built.
The -300 was an increased gross weight version with a 9 meter stretch for high density routes. Proposed for Japanese service, it lost out to the 747-100SR, and was not proceeded with. Most notable on this was the lower deck passenger seating. This cabin used the area in the stretch as well as the galley space, and what was the lounge space on the PSA Tristars.
The -400 was to take the fuselage of the -500 combined with the wings and landing gear of the -1. The resulting aircraft would have supported shorter, thinner routes.
The -600 'Bistar' took the -500, and removed the tail engine to provide a twin engine widebody with maximum commonality with the -500. The 1985 entry into service date would put it in direct competition with the A300/310 and the 767.
The Callieverse nose is an AU for Voyager's
Isle of California and represents the addition of the navigator's bay to the avionics compartment.
