Neptune-1 Medium Launch Vehicle 2.51 2012-09-29

The Neptune-1 is a low-cost medium launcher conceived to lift payloads in range of 10/13 t in Low Earth Orbit, as commercial and military satellites or resupply modules for the International Space Station. His overall configuration is a derivation of the Uranus rocket, realized for the Poderosa I capsule, another well known add-on of the Orbiter Italia Forum. Neptune-1 is a two-stage rocket; an optional Fregat third stage / space tug (included in the package) can be added for GTO and GEO launches.
The Neptune-1B is a version with a more powerful, cryogenic second stage powered by a single J-2S engine and a payload capacity of about 17 t to Low Earth Orbit.New features of the version 2.51:
