does anyone know if NASA uses the same classification system for their motors? like, S,T,U,V like the alphabetical way, the same way that us amateur rocketeers do?
thats what i was trying to figure out. what the classes of the saturn V were. i figured that it would be close to a full V motor, but i didnt compensate for the burn time.
If I remember correctly (which is doubtful, no doubt... ), the 2nd stage had 5 J-2 motors and the 3rd stage had a single J-2 motor so Stage 3 should be "AB" (or 1/5 of the stage 2 which is listed as "5XAB")
