Here's an interesting study from Sept of 64, entitled "Orbital Launch Potential: Saturn IB Earth Launch Vehicle Using Solid Propellant Motors".

This study not only covers the use of large monolithic SRMs for first stage replacements, but also the clustering of smaller 120 inch Titan III SRMs for first stages, and also the possibility of clustering 156 inch SRMs for first stages, as well as investigates the possibilities and performance available from adding a pair of 120 inch Titan III SRMs or 156 inch segmented SRMs to the side of the existing Saturn IB first stage as SRBs, either dropped in-flight or bolted to the stage and carried through the liquid S-IB first stage burnout. Performance gains of up to 170% over the standard Saturn IB payload to orbit were possible, with an upgraded S-IVB stage on top.

Enjoy. Pics to follow... OL JR
