Unlike other rocket companies like ULA, SpaceX, or Rocket Labs, Rainier Aerospace will be betting with re-usable space planes to compete in the private sector of the space industry, and bring affordable satellite launches, as well as be a good candidate for space-station re-supply missions.

Rainier Aerospace also intends on establishing orbital "solar farms" that can transmit wireless electricity to Earth and future interplanetary space ships via lasers.

Below includes our current projects and designs, which includes our newest "Endeavor" rocket-plane launch system.


Rainier "Endeavor" Rocketplane; A low-cost, re-usable rocket-plane launch system that is capable of launching cubesats & small satellites into orbit for around $3-$4 million. The rocket-plane launches a 2nd stage "Orbital Maneuvering Vehicle" at it's apoapsis, and from there the OMV continues to the desired orbit to release its commercial payload. Endeavor is Rainier's first step into the space industry, and while not an SSTO, it is capable of further revolutionizing space access by drastically reducing costs per launch. The Endeavor will be capable of launching from a conventional runway, mobile launch pad, 747-400 air-launcher, and a sea-launch ship. Although for runway launches, the Endeavor is more than likely going to be limited to either Vandenberg AFB, Cape Canaveral SLF, or Patrick AFB, due to the heavily populated areas surrounding land-locked Moses Lake, WA in all directions. But by default, 747-400 air launch operations will be based out of Moses Lake/Grant County International Airport, where the 747-400 will carry the Endeavor off the coast of Washington state in the open Pacific for a safe air-launch away from the heavily populated Seattle and Portland areas. 747-400 air-launches will also be available on the Space Coast in Florida at the customer's request. The mobile launch pad launches will allow launches almost anywhere, but again, due to population areas, will be restricted to Vandenberg AFB & Cape Canaveral launching facilities. The sea-ship floating launch pads will be based in the Port of Everett, WA, and will carry the Endeavor launch system out to the pacific off the coast of Washington just like the 747-400, and it too will be able to launch off the coast of Florida in the Atlantic depending on the customer's demands. The 747-400 and sea-launch pad ships will be the most flexible forms of launching the Endeavor rocket-plane launch system.

First conceptual rendering of Rainier's rocket-plane concept in SimplePlanes. The craft was originally termed "Ermine", and Rainier's rocket-plane launch systems series was to be named after members of the mustiladae family, but that has since been changed.
