The Starfleet science ship given to Captain Lynne Lucero, lost when the tribbles engineered aboard by the scientist Edward Larkin multiplied out of control.
The USS Cabot is a Starfleet science vessel in the Short Treks episode The Trouble with Edward. Lynne Lucero leaves Christopher Pike's Enterprise to take it as her first command.
The Cabot is sent to help a starving planet. One of its scientists, Edward Larkin, proposes breeding tribbles as food. Lucero rejects the idea and moves to transfer him, and he carries on in secret, altering the animals with his own DNA. The result is a tribble that is born pregnant and breeds at a frightening rate.
The creatures fill the ship from deck to deck. Lucero orders the crew to abandon it, Larkin is buried under his creations, and the Cabot breaks apart. At the inquiry Lucero sums up the cause in very few words.
