The ZGMF-X20A Strike Freedom Gundam (aka Strike Freedom, Freedom) is the successor of the ZGMF-X10A Freedom Gundam introduced in the anime Mobile Suit Gundam SEED Destiny. It is piloted by Kira Yamato.
A mobile suit tuned to meet Kira Yamato's needs, the Strike Freedom has Variable Phase Shift armor, and like its predecessor, ZGMF-X10A Freedom Gundam, is primarily armed with powerful ranged weapons. Its armaments include head-mounted CIWS, an abdomen-mounted multi-phase beam cannon, hip-mounted railguns, combine-able beam sabers and beam rifles, DRAGOON pods controlled by the new Super DRAGOON system and beam shields. It is powered by the new Hyper-Deuterion Engine, and is also equipped with the Neutron Jammer Canceller and the Voiture Lumiere propulsion system.
Due to Kira's stellar piloting, his mobile suit is rarely hit during combat and thus Strike Freedom's design emphasizes maneuverability over its armor's defensive capabilities, though beam shields were installed as a compensatory defensive measure. As a result, its armor is split into smaller pieces to improve the movement range of the joints (a similar armor-splitting system was also implemented in ZGMF-X42S Destiny Gundam). To compensate for exposing more of its internal parts, the suit's internal skeleton and joints adopted PS armor materials. When these parts phase-shift, they gain strength and near human flexibility. Additionally, excess residual energy within the body can be discharged through the joints' glowing effects.
The internal PS armor materials also help to withstand the massive output and Gs caused by the Hyper Deuterion engine and the new propulsion system, playing a role in increasing Strike Freedom's mobility. However, the main contributor to the MS's superior mobility are the mobile weapon wings, which can be deployed in the "High Mobility Aerial Tactics (HiMAT)" Mode to enhance the suit's mobility in the atmosphere or in space. The wings also features a variant of the "Voiture Lumiere" propulsion system, which can generate a visual effect called the "Wings of the Skies" similar to ZGMF-X42S Destiny's Wings of Light and is used as a means of high speed movement.
The Strike Freedom's Super DRAGOONs are based on ZAFT's second generation DRAGOON system, with additional unique modifications. Designed for Kira's use, they allow him to hit more targets at once using the Multi Lock-On System and Full Burst Mode as compared to when he was piloting the original Freedom. They also grant Kira the ability to hit the enemy from multiple directions remotely. Like the Freedom, Strike Freedom is designed to operate alongside another mobile suit, in this case, the ZGMF-X19A ∞ Justice Gundam and is stationed on board the warship Eternal. It also has full flight capabilities in the atmosphere and can dock with the METEOR unit to further augment its firepower.
