The USS Franklin is one of Starfleet’s most decorated ships, despite having disappeared over 100 years ago. It was the first ever Earth ship capable of reaching warp 4. After many successful missions, the Franklin mysteriously vanished after travelling through the Gagarin Radiation Belt. It was found in the year 2263 by the crew of the Enterprise. They were able to utilize the ship’s antiquated technology to defeat Krall and his Swarm.
