<prompt> Kwenzekani kumodeli wokuqala owaba i-Saturn IB? Ingabe kwakunjalo? Njengoba kunikezwe umbuzo odlule, bhala umongo onempendulo yawo. Kungaba imisho engu-1 kuya kwengu-20. Umongo:  <response>: I-Saturn IB kwakuyinguqulo ethuthukisiwe ye-Saturn I. Isigaba sokuqala se-S-IB sandise umfutho we-1,600,000 pounds-force 7,120 kN, kanti isigaba sesibili sathatha indawo ye-S-IV nge-S-IVB-200, enikwe amandla yinjini eyodwa ye-J-2 evutha uphethiloli we-hydrogen onamanzi nge-LOX, ukukhiqiza i-200,000 lbf 890 kN yokugqugquzela. Inguqulo ye-S-IVB eyayingaqalwa kabusha yasetshenziswa njengesiteji sesithathu seSaturn V. I-Saturn IB ingathumela ngaphezu kwamakhilogremu angu-40,000 18,100 kg emzileni omncane womhlaba, okwanele i-CSM noma i-LM enophethiloli. Izindiza ze-Saturn IB zaqanjwa ngenombolo yochungechunge lwe-AS-200, AS ekhombisa i- Apollo Saturn kanye ne- 2 ekhombisa ilungu lesibili lomndeni wama-rocket Saturn.
