Star Trek: Every Starfleet Starship Class Ranked Worst To Best
40. Freedom Class (22nd Century)
The USS Franklin was the first Starfleet ship capable of reaching Warp 4. It was a precursor to the NX class, armed with pulse phasers and spatial torpedoes. The Freedom class was a deep space ship, though it was not invulnerable by any means.
Once the USS Franklin came into contact with the Gagarin radiation belt, it vanished from Starfleet's scanners. It had crash landed on Altamid, though no rescue mission ever discovered the vessel in more than 90 years. The captain - Balthazar Edison - believed that Starfleet had abandoned them and was driven mad.
In the alternate reality created by the Romulan Nero, the Franklin was discovered by Captain Kirk and Lt. Commander Scott. They, with Jaylah, managed to get the ship operational again, getting them off the planet and back to Federation space in time to save Starbase Yorktown from Edison's mad plans to destroy them all.
