Saturn-Apollo 5 Spacecraft: (no serial number) Launch Vehicle: Saturn I Blk II SA-5 Launched: 29 Jan 1964

⇑ Mission List ⇑ Designation: Apollo S1 P LV2(N)-1 Description: 1st Saturn I Blk II suborbital

This was the first flight of the Saturn I Block II configuration (i.e., lengthened fuel tanks in the S-1 and stabilizing tail fins), as well as the first flight of a live (powered) S-IV upper stage. The S-1, powered by eight H-1 engines, reached a full thrust of over 680,400 kilograms (1.5 million pounds) the first time in flight. The S-IV's 41,000 kilogram (90,000-pound-thrust cluster of six liquid-hydrogen RL-10 engines performed as expected. The Block II SA-5 was also the first flight test of the Saturn I guidance system.
