I-a2b solar ionization reactor

The I-a2b solar ionization reactor was a stardrive system developed and produced by Sienar Fleet Systems.Star Wars Technical Journal
==Characteristics==
Often described as a "miniature sun", and incorporating one of the largest single hyperspace field generators ever designed, the massive reactor system occupied more than half of the Imperial-class Star Destroyer's interior. Unlike the reactor system on the older Venator-class,Star Wars: Revenge of the Sith Incredible Cross-Sections the reactor on board Imperial-class vessels was large enough relative to the rest of the ship to protrude with a ventral bulb. It also forced the troop and crew compartments to be located on the upper half of the superstructure.Star Wars: Incredible Cross-Sections
Like other heavy warships, it was the size of the power-plant which in turn dictated the size of the Imperator-class.HoloNet News — A Galaxy Divided Lira Wessex and her team at Kuat Drive Yards designed the rest of the Star Destroyer around the Sienar drive systems.
A version of the I-a2b was later adapted for use in the Bakura-class destroyer.Cracken's Threat Dossier
==Behind the scenes==
In some sources such as The Farlander Papers and Star Wars: Complete Cross-Sections, the Sienar Fleet Systems I-a2b solar ionization reactor is listed as the power system of small fighters such as the TIE Fighter and the TIE Bomber, despite both Complete Cross-Sections itself and other sources describing it as this article does; a massive power plant that occupied more than half of an Imperial Star Destroyer's interior. There is no known official explanation for this, and while it is possible that SFS produced multiple sizes of the reactor model, this is a considerable stretch of logic as the designation string would have different letters.
