The F71B type S.D. G-Cannon Magna Super Destroid was featured on the Mobile Suit Gundam Silhouette Formula Official Handbook included in the Bandai 1/100 scale RX-99 Neo Gundam model kit and designed by Kunio Okawara.
The F71B type S.D. G-Cannon Magna Super Destroid combines some experimental systems (e.g. the prototype firearms devices, the leg booster packs, the right shoulder camera scope unit) tested by SNRI on F71 G-Cannon Full Equipment Type and F90D Gundam F90 Destroid Type with those installed on Anaheim Electronics's F71B G-Cannon Magna. It is deployed during January UC 0121 by EFF 301st MS Company to attack an Oldsmobile remnant base in the shoal zone near Side 4.
