Solar Dynamics

Solar Dynamics was an interplanetary civilian company that was the premier manufacturer of nuclear reactors in the late 25th and early 26th centuries. The company manufactured nuclear reactors for civilian and military applications, and maintained their dominance of the market through the Human-Covenant war. Only the total destruction of their facilities on Reach and competition from the Strewn Shore knocked them out of first place.

Product Lines

 * Starship Reactors:
 * SP860: A second-generation cold fusion reactor that was released onto the market in 2512, the SP860 was a high-performance powerplant intended for military applications and in particular competed with Naoto Technologies' V4-series reactors. Although it was excellent by itself, with great metrics in terms of startup times, ruggedness, and overall output, Solar Dynamics made the unwise decision to pair it with their own in-house fusion drive despite having no prior experience with building propulsion systems. As a result, the exceedingly-poor performance of the drive destroyed whatever positive reception the SP860 might have gotten, and plans for using it as a basis for a family of related systems were scrapped. Despite this, the SP860 did see some success; the majority of production was bought at a discount by the CMA and subsequently used in their.
 * XSU-940: Experimental reactor incorporating many advances that were gleaned from or inspired by captured Covenant technology. Three manufactured, the first of which was installed as the primary reactor on the UNSC Pillar of Autumn.


 * Aerospace craft powerplants:
 * AP550:
 * AP630: Compact fusion reactor with a maximum output of 80 megawatts. Notably one of the most cost-effective compact nuclear reactors ever manufactured by Solar Dynamics, so much so that the design was spun off into a line of emergency power plants for civilian energy grids. Used in the UV-34 Rook.
