Delta Lite rocket 3D model

Delta Lite was a proposed Delta variant in the mid 1990s. The Delta-K upper stage and fairing would have been common with the standard version, but the Extra-Extended Long Tank Thor core and GEM boosters would be replaced by 2 Castor 120s. Castor IVB strapons were available as well, boosting performance nearly to Delta Med-Lite levels. At least 2 missions were actually contracted, but McDonnell Douglas shifted them back to the standard Delta due to low demand
