Every Starship Enterprise Saucer Separation In Star Trek & Why

Desperate times call for a saucer separation.
As seen in TNG, some versions of Star Trek's Enterprise can conduct a saucer separation to gain a tactical advantage or flee emergency situations.
Star Trek: The Next Generation is the third installment in the sci-fi franchise and follows the adventures of Captain Jean-Luc Picard and the crew members of the USS Enterprise. Set around one hundred years after the original series, Picard and his crew travel through the galaxy in largely self-contained episodes exploring the crew dynamics and their own political discourse. The series also had several overarching plots that would develop over the course of the isolated episodes, with four films released in tandem with the series to further some of these story elements.
