The second-generation RocketMotorTwo engine was a variant of the earlier SNC basic design, but was fueled by polyamide plastic fuel, while continuing to use the same nitrous oxide oxidizer. The second-generation engine was made in-house by Virgin Galactic rather than by SNC. By December 2012, 15 full-scale tests had been successfully conducted,<ref name="TestFires09-12">[http://www.scaled.com/projects/rocketmotortwo_hot-fire_test_summaries RocketMotorTwo Hot-Fire Test Summaries] {{Webarchive|url=https://web.archive.org/web/20120426095422/http://www.scaled.com/projects/rocketmotortwo_hot-fire_test_summaries |date=26 April 2012 }} Scaled.com Updated 9 August 2012 Retrieved 16 December 2012</ref><ref name=June2012Tests/> and additional ground tests continued into March 2013.<ref>{{cite web|url=https://www.virgin.com/richard-branson/blog/this-isnt-sci-fi|title=This isn't sci-fi|publisher=Virgin.com|date=5 March 2013|access-date=5 March 2013|url-status=dead|archive-url=https://web.archive.org/web/20130307153321/http://www.virgin.com/richard-branson/blog/this-isnt-sci-fi|archive-date=7 March 2013}}</ref> In June 2012, the [[Federal Aviation Administration]] (FAA) issued a rocket testing permit to Scaled Composites, allowing it to begin SS2 test flights powered by RocketMotorTwo;<ref name=FAAPermit2012>{{cite web |url=http://www.flyingmag.com/news/spaceshiptwo-gets-thumbs-rocket-powered-flights|title=SpaceShipTwo Gets Thumbs Up for Rocket-Powered Flights|publisher=Flying Magazine|date=1 June 2012}}</ref> the first such powered flight took place on 29 April 2013.<ref name=scaledsum130429/> The engine produced {{cvt|270|kN}} of thrust.
