T O P I C R E V I E WGACspaceguyThe title calls this item an "APOLLO SERVICE PROPULSION" engine but it is not. I thought it was an engine for a Titan but does not look like the pictures I have of those engines. Any help in knowing what this really is?Greggy_DScott in 3... 2... 1.SpaceAholicIt's an LR-87...mikejI'd say that it is an LR-87 (Titan first stage) nozzle (e.g., compare to this one).Usually it has the white covering over the combustion chamber, but it has the same shape of the nozzle, throat, and combustion chamber, and also has the propellant manifold a the top.GACspaceguyThanks for the info. There must be two configurations as it does not like this one at Udvar-Hazy.SpaceAholicThe chamber available in the ebay listing is from the -AJ7 or later variant.
