A subclass of the C-class cruiser more suited for patrol duties in systems lacking in orbital infrastructure, the Grainger class traded 6 of its railguns for laser clusters along with smaller (and more basic) missile banks. Other less obvious changes include a reduction of the number of whipple shields [less overall armor], the less powerful (but also less maintenance intensive) sensor suite. As expected though there were a number of subtle upgrades in terms of habitability. As with their parent class, these ships were simple, sturdy vessels, with reasonable maintenance needs. Handling and performance was similar though greater due to various weight reductions. All completed ships give solid, though undistinguished, service in the Federation Star Corp until their decommission in the early 2480s. The Londonderry served further on in the star navy of the Directory as the depot ship DH-004 until its hurried reactivation during the First Contact War, in which it was destroyed with all hands along with the rest of the Directory's Home fleet at the Battle of Daka. The second batch of 4 ships were cancelled in 2432 as the beginning of the massive cuts that characterized the decline of the Terran Federation during this era.
