Spacex is transforming its rocket factory. It is going from building six or eight rockets cores a year to about 18 cores a year. By the end of 2016 Spacex should be at over 30 cores per year.
Beyond ramping up production of its Falcon 9 at the company’s factory, SpaceX is increasingly focused on preparing its Falcon Heavy. The more powerful rocket is slated for its first launch during 2016.
