SD command satellite.

The Orbital Defense Network was a cheap, large scale operation designed to protect Vekta against the Helghast's growing military power, while at the same time saving money by not requiring a large fleet of cruisers.


The system would have an orbital command post that would also be the largest of all the defensive satellites. By the start of the Second Extrasolar War only the SD Platforms were completed, and shut down as the Helghast fleet deployed its troops onto the planet.
