Sometime in the 2250s or early 2260s, Captain Lynne Lucero assumed command of the Cabot. Her first mission brought her and the Cabot to Pragine 63, a planet on the edge of Klingon space which was facing starvation.
Shortly after, scientist Edward Larkin brought to Lucero's attention that he could modify the DNA of tribbles in order to increase their reproductive rate for use as a food source. Captain Lucero denied his request. Larkin went against these orders, and used his own DNA to modify the tribbles' reproductive rate, much to the disgust of the crew. The tribbles quickly started breeding, now being born pregnant, and easily escaped containment infecting the ship's systems. Efforts to contain the tribbles proved ineffective, forcing the crew to abandon ship.
Eventually, the sheer force of the tribbles pressed against the bulkheads caused the ship to break apart, or suffering a "total and complete structural failure" in the words of Admiral Quinn, the Starfleet board-of-inquiry chairman, resulting in its destruction and the death of Larkin.
