Star Trek: Every Starfleet Starship Class Ranked Worst To Best
58. Helios
The Helios class Federation tug ship of the 23rd century was reminscent of the Malachowski and Hoover class vessels, while existing as a ship in its own right. Two of them were dispatched to tow the Enterprise back to Spacedock when the latter ship was severely damaged, attempting to scan the red bursts.
The ship was an enduring design, though had been consigned to museum duty by the 2380s. Two such ships, along with a Magee class vessel, were docked in orbit of Mars during the First Contact day celebrations. However, it can be assumed that these vessels were also destroyed in the synth attack that laid waste to the rest of the planet.
