Pleased with the favorable results exhibited by the SC type, the Space Forces Headquarters hoped to introduce an improved unit for the assault on the Zeon home territories.
However, the timeframe given to the development department was a completely nonsensical deadline of merely a single month to bring a design from plans to an completed, actual machine. In order to clear these unreasonable demands, the technical team diverted a GS frame that had progressed to the prototype stage as a means to shorten development time.
Three MS teams of the test type of this SP model would be deployed in combat at Solomon, and were also deployed with the G4 unit's Scarlet team. However, all of these units were lost in combat at Side 6.
