The MSZ-006A1 Zeta Plus is the Mass-Production version of the MSZ-006 Zeta Gundam originally built by Anaheim Electronics for Karaba’s Air Force. Since Karaba only operated on Earth, the MSZ-006A1 Zeta Plus removes any aspects of the Zeta Gundam intended for space use. This streamlining helps the MSZ-006A1 Zeta Plus outperform the Zeta Gundam in atmospheric combat scenarios. These units would remain in Federation service well into the 0090’s, as this HGUC rendition builds into the MSZ-006A1 Zeta Plus as seen in the Mobile Suit Gundam Unicorn animated series.
