Reaction Frame (Stardust Century)

Reaction Frame is a type of inner frame build created in 0092-SC by the Earth Union. It first appeared in Mobile Suit Stargazer Gundam.

Function
The purpose of the Reaction Frame is to protect the internal parts of a mobile weapon from getting damaged from a reaction to a blow to the outer armor. It adds a type of insulation in between the inner frame and the outer armor so that it absorbs the G-forces of the blow and keeps the internal wiring or mechanical parts from cracking or even breaking.
