I believe that the Titans had mmhydrazine...or something like that.

The Titan II (ICBM and Gemini booster) used Aerozine 50. That was 50% Hydrazine and 50% Unsymetrical DiMethyl Hydrazine, UDMH.

The Titan III and IV systems used the same fuel

Mono Methyl Hydrazine, MMH, was used in the Post Boost Control System for the Minuteman III ICBM.

Thanks - everybody for answering this.

I remember back in the 60’s one drag racer’s engine blew the block apart - they were experimenting with doses of MMH.
