Saturn IB Fin

The Cosmosphere displays a Saturn IB S-IB (first) stage fin; at least for a time, it also served as a projection screen for a movie.

The curator tells me that this is a test fin assembly, designed and built to aid in determining the best configuration for the fins on the S-IB first stages. Recall that the Block I Saturn I had no fins at all, the Block II Saturn II added alternating large and small stubby fins, and the Saturn IB had eight matching swept-back fins.

See my Saturn IB fin page for additional information.
