It says that the prototypes only were produced at the research plant on New Earth. The actual line production occurred on various worlds (probably Thermopolis for the FWL, Wernke-Talon for the FS, and ??? for LC) for the SLDF, since New Earth was obviously part of the Amaris Empire during the coup.
You know, I'm not sure that 20 prototypes &/or the 2770 intro date can be correct.
The intro date for the Wolvie is listed as 2770, but it was used in the Periphery along with the Atlas II in 2765.
1 of only 20 prototypes making it out to the periphery 5 years before the factory went full production?
That seems like a very long prototype testing phase as well as a really long way to go to test it.
Either way, as stated, its Operation Klondike that lists New Earth as the Original Factory.
