The Grayson class repair tenders were designed to fill the need for
full-time navigational beacon repair. The first assignments were well within
Federation territory, and therefore the first models were unarmed. However,
after several unpleasant encounters with pirates and marauders, it was
decided to give them a weapon for defensive purposes. This light armament in
no way makes the Grayson class ships combat vessels, but it allows for their
use as patrol ships in their duty areas.
