Soon after the end of the Bloody Valentine War, ZAFT began developing its next generation of mass production mobile suits. The ZGMF-X999A ZAKU Mass Production Trial Type was an early design in the New Millennium series. The trial ZAKU was equipped with a Neutron Jammer Canceler, which was first used during the war by the ZGMF-X09A Justice Gundam and the ZGMF-X10A Freedom Gundam. In addition, the trial ZAKU was equipped with Phase Shift armor. Its armaments included a pair of hip-mounted railguns and a pair of high frequency blade tomahawks. In December C.E. 71, a trial ZAKU undergoing testing in South America by civilian test pilot Courtney Hieronymus was attacked by the Earth Alliance’s new GAT-02L2 Dagger L mobile suits. In C.E. 72, ZAFT and the Alliance signed the Junius Treaty, which formally ended the war and prohibited the use of N-Jammer Cancelers and Mirage Colloid. To comply with the treaty, the trial ZAKU was redesigned to exclude the N-Jammer Canceler. The Phase Shift armor was also dropped, and the new treaty-compliant design was mass produced as the ZGMF-1000 ZAKU Warrior and ZGMF-1001 ZAKU Phantom.
