The Fac L-83 Model, a Delvin Constructs design, represented the Alliance to Restore the Republic's adaptation of the Model Fac L-113 light vehicle factory, which was originally utilized by the Galactic Empire. The Rebel Alliance commissioned and acquired these factories specifically to produce repulsorlift vehicles such as the T2-B repulsor tank and the T-47 airspeeder. These modified factories were deployed across the galaxy at existing hidden bases.
