For defensive purposes the Strike Freedom is equipped with beam shields which are mounted on its forearms. These rifles can be stored on the hips by having the rail cannons swivel to the rear of the suit. It also carries two high energy beam rifles that can combine into a longer, more powerful weapon similar to the GAT-X103 Buster's ability to combine its main armaments into a more powerful weapon. Apart from the head-mounted CIWS and 'Super Lacerta' beam sabers, the Strike Freedom is equipped with a pair of 'Xiphias 3' rail cannons on its hips, a smaller and more refined version of its predecessor, and a chest-mounted 'Callidus' multi-phase beam cannon.
The Strike Freedom is armed with new advanced weaponry, giving it several times the combat ability of the original Freedom thanks to advancement in technology which takes place in the roughly two year gap that separates their construction. It is based on the earlier ZGMF-X10A Freedom and is powered by the new Ultracompact Hyper Deuterion Nuclear Fission Reactor. The ZGMF-X20A Strike Freedom is a mobile suit built in secret by Terminal under the guidance of one of its components, the Clyne Faction.
