The MSZ-006A3 Zeta Plus A3 is a variant of the MSZ-006A1 Zeta Plus A1. The unit is featured in the photo-novel Gundam Sentinel.
Technology & Combat Characteristics
The Zeta Plus A3 has a higher performance over its predecessor the MSZ-006A1 Zeta Plus A1 with improved control fins.
Due to the adoption of the superior MSZ-006D Zeta Plus D unit, the A3 type is never placed in service, and only one prototype unit is constructed.
