Secondary hull

The secondary hull (also known as the engineering hull, the engineering section or the stardrive section) was a major component of the overall hull structure on Federation starships. In most Federation starship designs the secondary hull was located below and behind the primary hull, sometimes separated by an interconnecting neck.
The secondary hull was usually the location for the vessel main power generating unit, such as a warp core, and the ship's main engineering. This also meant that it was common for the ship's warp nacelles to be connected to the secondary hull. Due to the dangers of a mishap with the warp core many Starfleet designs were able separate their primary hull from the secondary hull.
