PROGRAMME: Tentative plan introduced for all-environ variable combat system for use against giants February 2002. UN Forces' basic requirement for system to incorporate aerospace fighting capability equal to the level of contemporary fighters and ground comabt capability comparable to Destroid series. Development began with United Nation Forces contract to Stonewell and Bellcom; Stonewell and Bellcom solicited the powerplant producer Shinnakasu Heavy Industry (co-developer of reaction engines) and ground weaponry maker Centinental (co-developer of Destroid series) as partners; development team completed basic design 2005; one non-transformable VF-X flight test machine and one transformable VF-X-1 produced; first flight February 2007; space-worthiness tests begin in June 2007. Decision made to formally introduce the VF-X1 November 2007.

Development and mass production of operational VF-1A started November 2007. Deployment begins on CVS-101 Prometheus carrier August 2008 (However, usage is limited to Fighter mode only). Total initial strength on SDF-1 Macross at space launch ceremony 1 February 2009: 212 VF-1 Valkyries. First operational deployment in Space War I's Battle of South Ataria Island the same day. First operational deployment of Protect-Weapon-system-equipped Valkyrie in space combat October 2009. First operational deployment of FAST-Pack-equipped Valkyrie in combat January 2010. Production resumed after Space War I at surviving parts plants in the space colonies and on the Lunar surface's Apollo Base August 2011. At the end of the 2015, production of the VF-1 series ended with the rollout of the final VF-1 in a commemorative ceremony. Scheduled to be replaced as main variable fighter by VF-4 Lightning III in 2020.
