Last year the DDS opened a new nuclear weapons production facility on Solaris and planned to open a second facility, with a research & development centre, on Remedia Prime in 2112. The Orchid has ordered plans be accelerated to reduce the dependancy on one facility though it is unlikely anything can come on-line before 2111.
The old facility on Proxima 7 was due to be decommissioned later this year but will now be kept active until it can be replaced by the Remedian facility. It's equipment is old but it can see produce warheads at a limited rate.
