Currently, 10/250 NLV-class test vehicles are already providing suborbital reusable launch services for NASA. The next generation of such pathfinder test vehicles developed under this program will extend the test envelope for enabling launch technologies and operations needed to effectively implement orbital NMSLV-based operations. Longer term, the NMSLV configuration that emerges from this effort will be able to support such NASA programs like LSP's ELaNA and the Edison small satellite research initiative. These can then be followed by launch and maintenance of global monitoring systems that feature low-cost CubeSat-class spacecraft. Current NLV-class test vehicles are now being used to manifest and evaluate a variety of new launch vehicle technologies, including composite cryo propellant tanks, alternative hydrocarbon fuels (methane, propane and propylene), wireless data networking, and advanced vortex engines under TRL-6 and 7 environments. The next generation of NMSLV-based test vehicles will expand these to TRL 8 and 9 conditions, while still providing secondary payload opportunities for small developers and STEM initiatives. Longer term, the resulting operational NMSLV can support the implementation of CubeSat-based commercial earth monitoring constellations, global space weather monitoring constellations for the Air Force, and rapid response for such organizations as the Army's SMDC and DOD Special Operations Command, as well as providing dedicated launch services for the DOD Space Test Program, Operationally Responsive Launch Office and the NRO's Colony II initiative.
