Boeing Small Launch Vehicle


The Boeing Small Launch Vehicle, or SLV, is an air-launched three-stage-to-orbit launch vehicle concept aimed to launch small payloads of into low-Earth orbit. The program is proposed to drive down launch costs for small satellites as low as per launch and could be fielded by 2020.

History

In July 2012, DARPA awarded Boeing a US$4.5 million contract to further refine the system concept as a part of the DARPA ALASA program.

Description

The first stage of the three-stage launcher would be an air-launched supersonic aircraft accelerating to a speed of at, while the second stage would be a hypersonic waverider aircraft which would accelerate the vehicle to at an altitude of. Both of the first two stages would be reusable to reduce launch cost, and both stages would carry only fuel, and obtain their oxygen for combustion from the Earth's atmosphere.
The third stage would be powered by a rocket, roughly long, to complete the acceleration of the payload to orbital velocity.
The carrier aircraft is projected to be a Scaled Composites White Knight Two.
