The Vosun-Voth Star Empire, rather misnamed these days seeing as the Voth have split to gain freedom and the rest is a virtual vassal state of the Bolitic Confederacy, have bought 4 Shark SK-E frigates as part of their fleet rebuilding efforts.
As well as indigenous warships the VVSE has also a collection of old Bolitic and Tarbot ships but the Sharks will be their most modern. They will be integrated into the joint VVSE-Bolitic Military Command by the Bolitic who will also perform some upgrades including info-weapons. It is understood that the VVSE (and Bolitic) are part paying for the ships with a transfer of info-warfare technology to the Clones.
