The FXA-00 Flying Armor was a custom sub-flight system created by Anaheim Electronics for the AEUG’s RX-178 Gundam Mk-II. Its distinctive shape was directly based on the waverider mode created by Mk-II pilot Kamille Bidan in his conceptual design for the MSZ-006 Zeta Gundam, making it both a practical support system and a proof of concept for transformable mobile suit technology.

History

The FXA-00 Flying Armor was developed in response to specific operational requirements faced by the AEUG during the Gryps Conflict. The organisation’s strategy relied heavily on conducting lightning-fast attacks against Earth Federation Forces installations, particularly major bases like Jaburo, launched from space-based positions.

However, the AEUG faced significant logistical challenges in conducting such operations. Whilst atmospheric re-entry was possible using traditional ballute systems, this method rendered mobile suits completely defenceless during the descent process. Additionally, the AEUG lacked the financial resources to employ large Heavy Lift Vehicles (HLVs) for deploying mobile suit forces to Earth’s surface.

Operation Jaburo

The Flying Armor’s first major operational deployment occurred in May UC 0087, when Kamille Bidan used it as part of the AEUG’s large-scale assault on the Titans’ Jaburo base on Earth. This operation marked a crucial test of both the Flying Armor’s capabilities and the broader tactical concepts it represented.

The successful use of the Flying Armor during the Jaburo operation demonstrated the viability of rapid atmospheric entry systems for mobile suits, proving that properly designed equipment could overcome the traditional vulnerabilities associated with orbital-to-surface operations.

The Flying Armor remained in active service when Elle Vianno took over as the primary Gundam Mk-II pilot, indicating its continued operational value beyond its initial proof-of-concept role.

Design

The FXA-00 Flying Armor represented a revolutionary approach to mobile suit atmospheric operations, combining the functions of a sub-flight system and an atmospheric re-entry vehicle in a single platform. Its design was directly inspired by Kamille Bidan’s conceptual work on what would become the Zeta Gundam’s waverider mode.

Configuration and mounting

The Flying Armor was designed to accommodate the RX-178 Gundam Mk-II in a secure mounting configuration. The mobile suit’s feet locked into designated positions at the top of the rear section of the craft, providing a stable mounting point during flight operations.

For situations requiring additional security or when carrying two mobile suits, the Flying Armor featured two additional sections at the front containing grips. This allowed the Gundam Mk-II to lock into the Flying Armor with all four limbs if necessary, ensuring maximum stability during high-stress manoeuvres or emergency situations.

Dual functionality

The Flying Armor served two primary operational roles. As a sub-flight system, it provided enhanced mobility for mobile suits operating in Earth’s atmosphere, allowing for high-speed flight over long distances whilst conserving the mobile suit’s own energy reserves.

More critically, the Flying Armor functioned as an atmospheric re-entry system, solving one of the AEUG’s most pressing tactical problems. Unlike traditional ballute systems that left mobile suits vulnerable during descent, the Flying Armor maintained the mobile suit’s operational capability throughout the re-entry process.

Technological foundation

Beyond its immediate practical applications, the Flying Armor served as a crucial proof of concept for Project Zeta. The aerodynamic principles and transformation concepts tested in the Flying Armor’s design directly informed the development of the MSZ-006 Zeta Gundam’s Variable Mobile Suit and WaveRider System (VMSAWRS).

The success of the Flying Armor demonstrated that mobile suits could indeed be effectively integrated with atmospheric flight systems, validating the theoretical foundation for the more advanced transformation systems that would characterise the Zeta Gundam and subsequent transformable mobile suits.

Operational capabilities

The Flying Armor excelled in providing rapid deployment capability for AEUG mobile suit forces, enabling the kind of fast-strike operations that became the organisation’s tactical signature. Its atmospheric entry capability was particularly valuable for surprise attacks, as it allowed mobile suits to appear over Earth-based targets with minimal warning.

The system’s effectiveness in Earth-based operations made it an essential component of AEUG strategy during the middle phases of the Gryps Conflict, when control of Earth’s surface installations became increasingly important to overall campaign success.

Behind the scenes

The FXA-00 Flying Armor was designed to serve multiple narrative purposes in Mobile Suit Zeta Gundam. Beyond its immediate tactical role in the series, it functioned as a visual and conceptual bridge between the static mobile suits of the original Mobile Suit Gundam and the transformable mobile suits that would define Zeta Gundam.

The direct connection between Kamille Bidan’s conceptual design work and the Flying Armor’s shape emphasised the character’s role as both a pilot and an engineer, whilst foreshadowing the eventual development of the Zeta Gundam itself.

The Flying Armor’s design also reflected the series’ emphasis on practical military logistics, addressing the real operational challenges faced by the AEUG whilst introducing concepts that would become central to later mobile suit development.
