Technology & Combat Characteristics
The GD Cannon was the second mobile suit of the GD (pronounced "Jeed") "Gun Defender" series. It was developed from the RGD-X1 GD Striker as prototype for the next mass production artillery mobile suit of the Earth Federation Forces.
History
Only a small number of prototypes were produced for testing before development was discontinued. In fact, the design of GD series lost the competition against the RGM-89 Jegan and its variants to be the EFF's next mainstay MS.
