The Delta Plus is based on the MSN-001 δ Gundam, a transformable MS designed during the Gryps Conflict that, because of problems with insufficient frame strength, was completed as the non-transforming MSN-00100 Hyaku Shiki. CG models of the Delta Gundam exist on the net, though a variant, the MSN-001X Gundam Delta Kai was built for demonstration purposes. While Anaheim Electronics was trying various approaches to develop a production model of the Zeta series as a transformable MS, it also simultaneously conducted a reinvestigation of the shelved Delta plan and the Delta Kai, creating the MSN-001A1 Delta Plus as a result. It is said that a few units of the Delta Plus were produced as a limited mass production prototype. As the Delta Plus is a non-standard prototype that is hard to incorporate into a normal team formation, the Delta Plus was assigned to the Nahel Argama in UC 0096, which is likewise a non-standard ship that often operates on its own.
