How Much Will SLS Actually Cost?

NASA Solicitation: Space Launch System RS-25 Core Engine

"In developing the SLS, the Act directed the Administrator to utilize, to the extent practicable, existing contracts, investments, workforce, industrial base, and capabilities from the Space Shuttle Program (SSP), Orion, and Ares I projects. This includes SSP-derived components and Ares I components that draw extensively on SSP heritage propulsion systems, including liquid fuel engines, external tank or tank-related capability, and solid rocket motors. To achieve this mandate, NASA initiated the development of the SLS with SSP and Ares I derived assets. Specific to the Core Stage Engine, the system will utilize modified RS-25 Space Shuttle Main Engine (SSME) hardware and Ares I components to provide the required lift capabilities. This procurement action is to acquire six additional RS-25 Core Stage Engines. These six flight engines in combination with the available RS-25 residual inventory will support the SLS flight manifest through the first five flights."

NASA Solicitation: Space Launch System Exploration Upper Stage Engine

"The National Aeronautics and Space Administration (NASA) invites Industry to submit a response to this Request for Information (RFI) to assist NASA in the planning for a new Exploration Upper Stage Engine (EUSE) acquisition development."

Keith's note: Funny how NASA makes these overt statements about using Ares stuff - stuff that cost billions - and yet when you ask how much SLS costs they never seem to include the cost of all the Ares stuff.
