Wallenberg class

The Wallenberg class was a Federation starship type, a transport class in Starfleet service in the 2380s decade. 

History and specifications
Following the revelation of an impending supernova of the Romulan star Eisn in 2381, Starfleet mounted a relocation operation for affected worlds. The USS Nightingale (Wallenberg class) was a Wallenberg-class transport refitted for people mass transport while a dedicated rescue armada was under construction at the Utopia Planitia Fleet Yards. 

The Nightingale was involved with relocating Romulan citizens from the Eisn system. 

Background
The class may be named for the Human Raoul Wallenberg, who used his position as Swedish diplomats to save tens of thousands of Hungarian Jews from the Holocaust on Earth in the 20th century.
