RGM-109 Heavygun

The Heavygun is a mobile suit which appears in the movie Mobile Suit Gundam F91.

History
The Heavygun was the first successful mass produced next generation mobile suit created by Anaheim Electronics and then sold to the Earth Federation Forces. The suit was intended to replace the aging RGM-89J Jegan Normal Type and quickly proved to be a popular model among the pilots. This caused the Heavygun to remain in service for several decades.
