Missileer carriers not on deployment have now completed Missileer Update 2109 A which includes Ferret-G support. The two ships on deployment will receive their updates when they complete their deployments so it should be within the next couple of months.
The DDS have also been talking about how they plan to improve the Missileer in future to further cement it's role as a mothership and centre of DDS deployments. Accommodation will be greatly enhanced next year and the docking bay will be totally redesigned and extended. There will also be further improvements to the communication systems.
