The HCS Space Navy have announced 2 new unmanned space vehicles and have given October 1st as the entry into service date of Sprite-NG, their Ferret equivalent. The first new vehicle is called Horizon HZ and is said to be an unmanned medium sized transport. This ship will be used for standard transport missions between planets and bases deep in the CSE. No entry into service has yet been given.
The other USV is the Vokoran VK, the HCS are being much less open about what the Vokoran actually is. It is rumoured it could be an upgrade to the Nybble NL that can conduct counter-space missions though other sources indicate it is science drone.
