Star Trek: Every Starfleet Starship Class Ranked Worst To Best
62. Wallenberg
The Wallenberg class ship was a large ferry, constructed in orbit around Utopia Planitia, with the sole purpose of evacuating nine hundred million Romulans to safety in advance of the impending supernova. They had been used with success during the 2380s to get many Romulans to safety, including those who settled on Vashti.
However, on April 5, 2385, the synth workforce on Mars launched a devastating attack which destroyed the surface of the planet - along with many thousands of lives - ensuring that the Wallenberg fleet was wrecked in the process.
This class was named for the Swedish diplomat Raoul Wallenberg, who was responsible for saving thousands of Jews in Budapest, during the Second World War.
