The ZGMF-X20A Strike Freedom Gundam, often referred to as Strike Freedom or simply Freedom, emerges as the evolutionary successor to the ZGMF-X10A Freedom Gundam, captivating the screens in the anime Mobile Suit Gundam SEED Destiny with the skilled piloting of Kira Yamato. Customized to meet Kira's combat demands, the Strike Freedom boasts Variable Phase Shift armor, aligning with its predecessor's reputation for dominating long-range confrontations through its formidable arsenal.

Strategically armed, the Strike Freedom features head-mounted CIWS, an abdomen-mounted multi-phase beam cannon, hip-mounted railguns, and an innovative array of weapons such as combine-able beam sabers and beam rifles. The pinnacle of its firepower lies in the DRAGOON pods, governed by an upgraded DRAGOON system, and the protective beam shields. Propelled by the cutting-edge Hyper-Deuterion Engine and complemented by the Neutron Jammer Canceller and Voiture Lumiere propulsion system, the Strike Freedom stands as a pinnacle of technological prowess.

Incorporating Variable Phase Shift armor, the mobile suit prioritizes maneuverability over defensive capabilities, featuring armor split into smaller segments to enhance joint movement. This unique design choice, akin to the ZGMF-X42S Destiny Gundam, allows for increased flexibility, strength, and phase-shifting of internal skeleton components. Residual energy discharge through glowing joints further emphasizes its technical sophistication.

The Hyper Deuterion engine and advanced propulsion system place immense demands on the Strike Freedom's structure. Internal PS armor materials play a crucial role in withstanding the strain, contributing to the mobile suit's exceptional mobility. The crowning feature enhancing its agility is the deployment of mobile weapon wings, executed in the "High Mobility Aerial Tactics (HiMAT)" Mode. This mode, usable in various environments, coupled with the "Wings of the Skies" visual effect, akin to ZGMF-X42S Destiny's Wings of Light, underscores the mobile suit's unparalleled speed.

The Super DRAGOONs, a customized evolution of ZAFT's second-generation DRAGOON system, equip Strike Freedom with enhanced targeting capabilities. Tailored to Kira's combat finesse, they introduce the Multi Lock-on System and Full Burst Mode, enabling precise and widespread attacks from multiple directions. Operating in tandem with the ZGMF-X19A ∞ Justice Gundam and stationed aboard the warship Eternal, the Strike Freedom further displays its versatility with full flight capabilities and the capacity to dock with the METEOR unit, amplifying its already formidable firepower.
