Technology & Combat Characteristics
As Zeon worked to upgrade its aging MS-06 Zaku II series during the One Year War, they intended to replace the space-use mobile suit MS-06F Zaku II with a new high-performance model the MS-11 Action Zaku. But it was still under development, a MS-06R-1A Zaku II High Mobility Type was heavily modified to serve as a testbed unit for the Action Zaku's development team. Incorporating the Action Zaku's powerful reactor and cooling system, the testbed Zaku II High Mobility Test Type could use beam weapons. The Zaku II High Mobility Test Type unit was so heavily and continually modified over its service life that it earned the nickname "MS-06R-3 Zaku III."

When the RX-78-2 Gundam with its hand-held beam weapons appears, Zeon engineers were forced to redesign the mobile suit. The MS-11 project was scrapped and Zeonic Company started on a new mobile suit called MS-14 Gelgoog. The plans for the MS-11 Action Zaku was later assigned to the Pezun Asteroid Base.
