In a parallel universe, the USS Mattingly was a small Starfleet vessel which evacuated the Deltan Prime Minister from Delta IV when it was invaded by the Borg and the Cybermen in 2368. (COMIC: Assimilation²)
Behind the scenes
Star Trek fans would probably argue that Mattingly is a runabout, as was featured most prominently in the first three seasons of Star Trek: Deep Space Nine. Danube-class runabouts were typically named after rivers on Earth, such as the Rio Grande, Mekong, Rubicon, Yukon, and Volga.
