M-III Launch Vehicle v0.1.1 2016-07-08


M-III is a medium/heavy launch vehicle featuring first-stage reuse capability through propulsive vertical landing on a pad near the launch site or a downrange landing platform (barge). All stages of the M-III launch vehicle have a 5.39-m diameter and use liquid methane/liquid oxygen rocket engines. The single-core M-III has a payload capacity of 14 to 21 tonnes to Low Earth Orbit (LEO) and 4 to 8 tonnes to Geostationary Transfer Orbit (GTO) depending on whether it is reused or not, while the three-core M-III Heavy (available in a future release) will be capable of launching approximately 60 tonnes to LEO when expended. The primary contractor of the M-III launch vehicle is Mikubishi Heavy Industries. Commercial launch services are marketed by Hatsunespace.
This launcher uses a modified version of BrianJ's Falcon9R source code:

Hatsunia is an alternate-universe version of Japan inspired by the virtual singingcharacter “Hatsune Miku.” There has been a successful fan petition to place images of her on JAXA’s Venus Climate Orbiter “Akatsuki,” as well as amateur space hardware and rocketry projects associated with Miku. For more information, please see this thread:
The M-III launch vehicle is mostly inspired by SpaceX’s Falcon 9.
Special thanks to Martin Schweiger for creating Orbiter, BrianJ for letting others use the Falcon9R source code, and many others in the Orbiter community for their support.
