The Type 25 is one of the most well known and widely used Frigates of Known space, mostly due to Ceres Dockyard Corporation GmbH deciding license out the basic design out to other nations and producers.

Originally intended to operate as a fast and independently operated scout vessel by the Federated Districts of Ceres Self Defense Force, the vessel quickly morphed into a 'Jack of All Trades' type of vessel capable of operating as a larger patrol craft for independent control.

The Type 25 is produced in large number by the Ceres Dockyard Corporation for other nations and are usually seen as a decent low cost alternative to other companies Frigates. Especially the Block II variant of the Type 25 was seen as a solid space craft and remained unchanged, aside from slight upgrades, for more then 40 years.

While Ceres Dockyard Corporation designed the hull for 100 years, with the appropriate maintenance, it appears that the design was rugged enough that many of the Block I vessels of the Type 25 still in service will remain in service for the 23rd century and into the 24th century.
