Cochrane (2372)
Cochrane was a Class 2 shuttle used aboard the  during its journey through the Delta Quadrant during the late 24th century. It was numbered "04" in order to register it as Voyagers fourth shuttlecraft, and was the shuttle used for Voyagers transwarp tests.

History 

In 2372, the Cochrane became the first Starfleet vessel to break the transwarp threshold after it was outfitted with a transwarp drive by the crew of the Voyager. During the experiment, the shuttle exceeded its original limitation of warp 4, eventually breaking the warp 10 barrier, and traveled at infinite velocity across the universe. The shuttle was later used by the experiment's pilot, Tom Paris in order to cause Kathryn Janeway to experience the same transformation that he had made. After this, the technology was not used to break the warp 10 barrier by the crew of Voyager ever again, while the shuttle itself remained in service. ()

The shuttle was briefly lost in an interfold layer, a region between space and subspace in 2373. ()

In 2374, the Cochrane was used by B'Elanna Torres and Tom Paris during an attempt to recover Voyagers warp core after it had been ejected from the ship. The shuttle was destroyed by the Caatati during the attempt over a dispute on the ownership of the core. The occupants at the time, Torres and Paris, managed to dress into environmental suits and escape the shuttle's destruction, albeit being left adrift in open space. ()
