F91 Gundam 

The F91 Gundam is a high-performance mobile suit developed by Earth Federation's Strategic Naval Research Institute. Considered a late member of the famous Gundam series, it was made almost fifty years (cartoon time) after the first Gundam, during a period of the Federation's decline.

Although smaller at 15.2 meters tall and 19.9 tons compared to 18.5 m and 60 t for the RX-78 the F91 was immensely more powerful, with an array of advanced weaponry, as well as the revolutionary beam shield, which is much more effective than the solid material shields.[citation needed] F91 inherited the versatile design of its predecessor F90 Gundam, able to adapt to 20+ different mission roles simply by changing gear packs.
